Welcome to ChloroFilms plant videos for CONTEST #4. Could be a BIG payday coming... Thank you for the entries! Damping-off Kurt Reinhart Technical Summary of video content: Damping-off is a movie short on the widespread but mostly unnoticed disease of plants. I say unnoticed because the plants appear to wilt away and most would conclude the cause was limitation of plant available moisture. The movie short exposes the secretive predation of plants, especially seedlings, by several types of pathogenic microbes commonly lurking in the soil. All content is of native plants and plant communities. Our heroine, black cherry, is one of the most valuable timber species in the USA and is the source of cherry wood used in fine woodworking. Many other plant species are affected by Pythium, however, the movie focuses on black cherry because it was the focus of Kurt’s research for several years. All time-lapse videos and still photographs are the copyright of Kurt Reinhart. Related content is also on Kurt’s educational website (http://www.iecology.net/). Warning: Plants were deliberately harmed in the filming of this movie. Music Confugium corvorum by Axis Mundi Actum found on Jamendo.com (part of the Creative Commons- http://creativecommons.org/licenses/by-sa/3.0/). Another good version of the movie can be viewed on Vimeo (http://vimeo.com/14715739). Damping-off will be entered in the (4th) Chlorofilms’ film contest (http://www.chlorofilms.org/).   Summary of video content:

Welcome to ChloroFilms plant videos for CONTEST #3. Could be a BIG payday coming... Thank you for the entries! Arabidopsis Flower in 3D David Livingston Technical Summary of video content: Pixel-based images (JPEG) were digitally cleared using color-keying. This allowed visualization of internal structures in 3 dimensions. The technique is ideally suited for in situ hybridization analysis to detect mRNA in an anatomical context. To illustrate the technique, we used 248 sections of an Arabidopsis flower that was paraffin-embedded and sectioned at 20 microns. Sections were stained with Safranin and Fast Green and photographed with a consumer-grade camera mounted on a Nikon Eclipse 50i at 20X. JPEG images were imported into Adobe After Effects, manually aligned and built into a 3D volume. The last part of the video assigns a number to each section providing a catalog of the sections. This allows the researcher to quickly find a specific section(s) used in the reconstruction. Additional Information: Flower provided by Prof. Robert Franks, North Carolina State University, Dept of Genetics. Distortion-free sections prepared by Research Associate Tan Tuong. Graphic consulting provided by Randy Gelman, BeltlineMedia, www.beltlinemedia.com For more information see: Livingston et al 2010. 3D volumes constructed from pixel-based images by digitally clearing plant and animal tissue.

The Nitrogen Fixation Cycle: Presented by Dr. Undergrad. Thomas Miller General Summary of video content: Dr. Undergrad presents a basic introduction to the Nitrogen Fixation Cycle. In this cycle nitrogen is fixated to become more biologically available to the organisms of the world. Nitrogen from the atmosphere will be fixated into a nitrate or the ammonium ion. Once fixated there are a number of processes that the fixated nitrogen can undergo to pass through the cycle until it returns back to the atmosphere. This video was made for a contest hosted by www.chlorofilms.org. Special thanks to Dr. Adán Colón-Carmona for suggesting the nitrogen cycle as a topic for a new video.   Forests Kurt Reinhart General Summary of video content: A movie short showing the lives of plants in natural forests. This short illustrates the dynamics of forests, their environmental variability, and the reproductive structures (flowers) of trees and forbs. All content is of native plants and plant communities. Additional Information: All time-lapse videos and still photographs are the copyright of Kurt Reinhart. Most time-lapse videos shown can be found, along with ecological narratives, on Kurt’s educational website (www.iecology.net/). Music was generously provided and licensed by Moby for noncommercial film use (http://mobygratis.com/film-music.html). Although this movie has been uploaded to YouTube, I prefer the HD rendering available on Vimeo (http://vimeo.com/10858272). This movie will be entered in the 2010 Chlorofilms’ film contest (http://www.chlorofilms.org/). dioon merolae (espadaña) Cecilia Guadalupe hernandez tondopo General Summary of video content: es un video que describe aspectos importantes de dioon merolae una especie conocida en chiapas como espadaña..... en el se muestran aspectos como morfologia, distribucion y su uso, asi como la importancia que tiene en una celebracion religiosa para algunos fieles catolicos.   Chloroplasts and programmed cell death Arunika Gunawardena Technical Summary of video content: Chloroplasts and programmed cell death This is a lace plant leaf undergoing developmentally regulated programmed cell death (PCD) to form perforations. This short video clip illustrates streaming in lace plant leaf cells over a gradient of PCD stages: left (early stage), right (late stage). Note chloroplasts number declined steadily as stages of developmental PCD advance. So where are these chloroplasts going? Wright, et al., (2009).

Presentan ramillas y hojas persistentes o deciduas, sus hojas son escuamiformes o aciculares, algunas veces dimorfas, son plantas monoicas; con estróbilos masculinos estaminados, agrupados como ametos, ya sean axilares o terminales, las brácteas y las escamas están parcialmente fusionadas, estas son peltadas o planas, en la que cada escama produce de 2 a 9 semillas. The family is known as ahuehuetes taxodiace or Sequoias, trees are grown. They have twigs and evergreen or deciduous, its leaves are squamiform or acicular, sometimes dimorphic, are monoecious, with staminate male strobili, grouped as amet, whether axillary or terminal, bracts and scales are partially fused, they are peltate or flat, in which each scale produce from 2 to 9 seeds   Pinaceae Luis Roberto Perez Marcelin General Summary of video content: Description from Deedra McClearn's Fern Blog website: Why a Fern Blog from La Selva Biological Station in Costa Rica? I live in the middle of a magnificent rainforest in Costa Rica, surrounded by an amazing diversity of plants and animals. Although I am a biologist, most of my work these days is administrative. A couple of years ago, two fern biologist friends got me started on a fern collection to help keep me connected to the forest. This back-yard hobby now encompasses more than 30 genera of native La Selva ferns. I have also started a research project, monitoring the production and longevity of fronds of three different fern species in the forest. All of you fern experts and enthusiasts in other parts of the world may enjoy seeing these ferns, communicating with me about fern biology, and suggesting topics and video clips for inclusion on this blog. We have prepared a series of YouTube video segments on various fern-related subjects and we will post one every so often.

Each question delivers what is currently known about this biochemical attribute in plants. The acoustic guitar music mixed with resonator bars and tapping, provides a soothing blend to the intense details that are being described in the questions. The animation simply facilitates our current understanding of the very first rate-limiting step in fatty acid synthesis. The video clip was made to publicly broadcast the scientific contributions that plant biologists have made to the field of lipid biochemistry. It is intended to serve as a useful teaching tool in undergraduate plant physiology and biochemistry courses across the world.   video cycadas chlorofilms carolina Sanchez Olmedo General Summary of video content: Generalidades de cycadas,Distribucion y especies en Mexico y Chiapas, especies en peligro de extincion. Additional Information: video elaborado para la materia de botanica II, de la facultad de ciencias biologica de la Universidad de Ciencias Biologicas de Chiapas. In the Heat of the Night Sharon Robinson General Summary of video content: This video introduces the fascinating world of Hot Plants, flowers that generate heat (thermogenesis) to release scents and attract pollinators. We look at three thermogenic plant species, the monocots Philodendron bipinnatifidium and Colocasia esculenta and the eudicot, Nelumbo nucifera. Some plants such as Philodendron and Sacred lotus are also able to regulate their floral temperature, maintaining their flowers at up to 30 ?C above air temperatures over several days. Our research team is investigating how plants produce this heat and how they can regulate their temperature so precisely. We are also interested in why the plants produce heat. Is it to release particular scents to attract pollinators, to give a heat reward to the insects or does it also help the plant’s reproductive development?

Welcome to ChloroFilms plant videos for CONTEST #2. Could be a BIG payday coming... Thank you for the entries! Triphyophyllum peltatum the clandestine carnivorous plant Siegfried R.H. Hartmeyer Technical Summary of video content: The African liana Triphyophyllum peltatum is the largest of all carnivorous plants (CP) on earth, but strange enough the rarest in cultivation. Due to civil wars and difficult conditions the Western African rainforests are poorly explored and for a long time not very much was known about the hooked leaved lianas of the botanical family Dioncophyllaceae. Thanks to the generous donation of photos from a pioneering project at the University Wuerzburg (Germany) by Dr. Jan Schlauer and Dr. Heiko Rischer, and even first video shots from the habitat in Sierra Leone by Stewart McPherson, we are now able to show the complete live-cycle of the really clandestine carnivorous plant Triphyophyllum peltatum. This film has been edited as a lecture for the European CP Conference 2008 in Mira, Italy. Additional Information: I confirm that we (my wife Irmgard and I) own the copyright for this documentary and that we have the permission by Dr. Jan Schlauer, Dr. Heiko Rischer and Stewart McPherson to use their photos and video for our movie.   Sophisticated survival strategies of the annual Drosera Siegfried R.H. Hartmeyer Technical Summary of video content: This footage shows the sophisticated survival strategies of the annual sundews. Living a full life-cycle, from germination to flowering and seed-production, within one single season needs highly effective trapping strategies to get enough protein. The sundews in section Arachnopus, Coelophylla and Thelocalyx manage that with the most prominent and fast snap-tentacles, yellow light reflecting lens-headed tentacles and other adaptations to make as much prey as possible, and to produce seeds even under bad conditions. Our film shows several pictures of these species that have never been shown before. Additional Information: We (my wife Irmgard and I) own the copyright for this film and have permission to use the picture of Dr. Barry Rice, and the SEM images made by Dr. Regina Kettering, for our common project with Prof. Dr. Stephen Williams, to investigate the lens-tentacles of Drosera hartmeyerorum. Enjoy Your Meal Part 1: Mice eating Nepenthes truncata Siegfried R.H. Hartmeyer Technical Summary of video content: Part 1: A garden pond wich contains small peaty islands for Darlingtonia, Dionaea, Drosera and Sarracenia does not only look nicely in the early summer, as it is also soon attracting small animal carnivores as amphibes, reptiles and predatory insects like dragon flies and mantis. But there is even more to be seen when a large Roridula dentata at our balcony catches a big wasp which is immediately attacked by a hungry Pameridaea bug. And things become actually dramatically with the pictures of our multifold mice killing Nepenthes truncata. Additional Information: We (my wife Irmgard and I) own the copyright for this video series in 2 parts.   Enjoy Your Meal Part 2: Enzyme-testing with Byblis, Drosera and Roridula Siegfried R.H. Hartmeyer Technical Summary of video content: Part 2: Carnivorous plants digest their prey with proteolytic enzymes, or they profit from the enzymes in the stomache of mutualistic arthropodes living on the plant. But how is it possible to detect the enzymes. Fortunately there exists a simple and cheap adapted photo-film test for plants with sticky traps that is suitable for your own experiments or the use in schools. This film shows the procedure of the test with Byblis filifolia, Byblis liniflora, Drosera adelae, and Roridula dentata. Also possible problems with the evaluation of the test strips are discussed in detail. Well, you may understand the end of this part 2 only if you have seen part 1(smile!). Additional Information: We (my wife Irmgard and I) own the copyright for this video series in 2 parts. Time-Lapse Characterization of Arabidopsis Starch Metabolism Mutants Zach Jarou Technical, Part of a Series Summary of video content: During the early exponential growth phase of plants, the majority of photoassimilates are reinvested into new leaf material. Leaf area, one of many growth parameters, has been examined by time-lapse photography in Arabidopsis starch metabolism mutants. The irregular shape of leaves can make measurement by traditional means difficult, especially for large numbers of plants. By taking a digital picture of the leaves to be measured, along with an object of known size, the pixel area of the leaves can be can quantified into physical units. This is accomplished using the color range and histogram tools in Adobe Photoshop. A screen capture demonstration of this process is available on YouTube (http://www.youtube.com/watch?v=E3O-V6WLw0g). The accompanying song, “Claire de Lune,” was composed by Claude Debussy and performed by pianist Van Cliburn.   Reincarnation of Trudy, a Titan arum in Berkeley Seung Yon (Sue) Rhee General Summary of video content: This video shows shows the rapid growth and 'flowering' of the inflorescence of Titan arum (commonly known as the corpse plant) at the UC Botanical garden in Berkeley in June of 2009. Affectionately called 'Trudy' by the garden staff, this plant grew at an average of 2-3 inches per day for about a week until the spathe (the dark purple 'skirt' of the plant) started opening on June 23, 2009. During flowering, the plant makes rotting-flesh smell by producing stinky metabolites, putrescine and cadaverine, to attract flies and beetles to pollinate. Out of Thin Air Nancy Muleady-Mecham General Summary of video content: This is a audio/visual reading of the illustrated book, Out of Thin Air, A Story of Big Trees, by Nancy Muleady-Mecham, submitted for consideration by www.chlorofilms.org botany movie contest. It is a story about where trees com from and how important they are to the carbon cycle of our planet. Illustrated by Robert Muleady, Designed by Sandra Kim Muleady. Copyright 2009 by Nancy Muleady-Mecham. Additional Information: The fidelity of the You Tube video does not do the film justice. It looks grainy and colorless compared to the original wmv which is available. Thank you.   Kenaf Callus Hoedown Noah Flanigan General Summary of video content: Our video is intended to be a quirky and fun, yet informative demonstration on the early steps required to initiate a plant tissue culture. We employed stop motion techniques throughout the film to show seed sterilization and germination to provide axenic plant tissue for culture. This is followed by sterile dissection of cotyledon and hypocotyl regions which were placed on a complete culture medium containing MS salts, vitamins, sucrose, an auxin, and a cytokinin to generate callus. Callus growth was followed over the course of three weeks. The resulting undifferentiated tissue dances with joy at the growth potential it possesses. A Leaf is born-The Microscopical Initiation of a Leaf through the Lens of a Scanning Electron Microscope Md. Shafiullah Technical Summary of video content: Plants produce food for other living organisms through a process called photosynthesis and the factory of the produced food is the leaf. How the leaf is produced from a mass of cells is shown in this video through the lens of a scanning electron microscope. This work is the part of the research project of Md. Shafiullah who created the video in collaboration with his supervisor C. R. Lacroix, Professor of Biology at the University of Prince Edward Island, in Canada.

I selected this music because its spontaneous dynamic changes and comic, upbeat melody pair well with the abrupt movement of the snap traps. Many clips are time-lapsed, sped up, and even played backwards, and although they might not reflect the accurate, real-time movement of the traps, they clearly illustrate a few points that are often overlooked about these fantastic plants: they grow in wet, swampy conditions, their trap leaves include hairs that initiate closing once they are stimulated twice by movement, and that the traps eventually reopen after closing. These are some of the details that are to be noted, as they are not common knowledge to most people. However, given the simplicity of the video, it is intended for a general audience, and will hopefully invoke amusement and speculation into the detailed workings of this magnificent and unusual plant. Additional Information: I hope you enjoyed it. It was fun to make! Pollination Methods: Solanum Part 1 Karl Haro von Mogel Technical, Part of a Series Summary of video content: Pollination Methods: Solanum is part of a series of step-by-step, instructional videos on how to make controlled crosses with plants. The videos will cover a wide range of techniques applicable to open-pollinated, insect-pollinated, and self-pollinated crops, ranging from agronomic to horticultural species. The controlled pollination method videos are technically-oriented and are targeted to high school and college students with some background in plant biology. They will be useful for students learning about plant breeding methods, and may be of interest to backyard and commercial hybridizers of various crops. The Solanum video explains the biology and origin of tomato and potato species and how to make controlled crosses with those plants yourself. Some of the methods commercial seed producers use are mentioned, and finally, the concept of polyploidy is explained with potatoes, and how breeders take it into account when breeding new varieties.

Vitamin C and Water in Plants Debbie Swarthout General Summary of video content: This video provides a description of the role that vitamin C plays in preventing plants from molecular damage caused by excess sunlight. Light-induced damage is a major limitation on crop productivity. This animation makes use of computational tools to produce a musical rhythym that follows part of the genomic sequence of a crucial mitochondrial enzyme that is used in the final production of Vitamin C (ascorbate) in the widely investigated mustard relative, Arabidopsis thaliana. A special set of rules was written to assign musical notes to the four genomic bases, A,T, G,C. It was fun writing the music notation from the genomic sequence. The video was created with the intention of educational use in high schools and undergraduate plant biology classrooms across the globe.

Plants Get Sick Too! (crpVideo)

Since the beginning of agriculture, farmers have developed methods for managing weeds, insect pests and diseases. Due to the significant impact from pests and diseases, on both human and animal health, it is important for those interested in plants to develop a firm understanding of weed science, entomology (study of insects) and plant pathology (study of plant disease), and how to minimize losses caused by these important plant pests. This video will highlight plant diseases and give resources for more information on plant pathology. Also visit the Chlorofilms web site for more videos on plants: www.chlorofilms.org.
