Pulvinus and movement in Byblis Siegfried R.H. Hartmeyer Technical Summary of video content: 14 days time lapse of Byblis liniflora show clearly that the carnivorous genus Byblis moves its leaves by pulvinus (thickening at the leaf or flower stalk base, enabling movement). This has first been noticed and published in 2008 by Brian Barnes (USA). Interestingly enough this amazing feature has apparently not been recognized or mentioned by other authors who described the different species of the Rainbow Plant in the past. We could find no text mentioning this fact prior to Brians examinations. Brian Barnes (USA) is ICPS director of conservation and president of the Florida CPS. The intention of our time-lapse experiment was to proof that Byblis actually moves its leaves and flowerstalks by growing Pulvini, and the resulting film became a clear evidence for this phenomenon. Additional Information: Meanwhile we know that all different species of the carnivorous genus Byblis develop Pulvini and move their leaves and/or flowerstalks. But such a movement, what is it good for? Easy to observe with our time-lapse: a new trapping leaf and a flower stalk (wearing one flower bud on the tip) both emerge from the leaf axil and both grow up erect to catch flying prey until the flower bud opens. Now a pulvinus is developed in the common leaf axil and the sticky trapping leaf moves down, not to endanger approaching pollinators. The flower is still hold erect. After pollination took place, the pulvinus shows a new thickening and now the flower stalk with the ripening seed-pod on the tip moves down and soon after that movement is finished, the seed-pot facing down to the soil opens and seeds are released without sticking to the gluey plant. Due to the fact that the mainly annual plants (except Byblis aff. gigantea) are rapid growers, the time-lapse of some plants looks like a fascinating group of ballet dancers.   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.

The origin of hydrocarbon-based fossil fuel is presented, highlighting ancient algae as an important component of keragen and the making of petroleum fossil fuels through geochemical processes through the ages. This is a prelude to the current explosion of interest in generating biofuel from living algae. The growth requirements for algae, their natural abilities to make lipids in some cases and how scientists can further increase lipid biosynthesis in green algae are discussed to illustrate the types of scientific research that is ongoing in laboratories today. Viewers are invited to learn more about Backyard Biofuels, a citizen science project launched in 2010 and directed by the Saint Louis Science Center and the Danforth Plant Science Center in St. Louis, Missouri. A call is made to all algae hunters encouraging them to donate algae samples from their own backyards and communities for the project. Viewers are challenged support real time science by collecting microalgae that could be new candidates for future algae biofuel production. Additional Information: The film’s narrator is Noah Engel, a 14-year old bright and articulate student who loves science. Noah comes to the Danforth Plant Science Center often to shadow scientists, and observe and ask questions. Noah’s voice is used in the video to engage in particular one target audience for “All Things Algae”: middle school science students. The video is designed to be shown in 6th-12 grade science classrooms, at the Danforth Center for educational programs, in the Saint Louis Science Center galleries and learning laboratories and at the annual Missouri State Fair, the St. Louis LouFest and other public gatherings. For classroom use, the 10-minute video can be shown in its entirety or it can be shown in two parts. There is a natural split built into the video about midway at “Microalgae Biofuel: Lab Research”. The video contains real footage from laboratories, greenhouses and growth rooms at the Danforth Center as well as images generated in the Integrated Microscopy Center there. Terry Thomas, who directs the Center’s Science Education and Outreach programs, is learning the skills and art of video making by taking evening adult education classes at Washington University and Webster University in St. Louis. Induce asexual mutation without any chemical or mutagene Trilok Sundar Mohanty Technical Summary of video content: The genetic change is stable as noticed in F2 The mutated cowpea plant produce Quadrifoliate/pentafoliate leaf in same generation as you see in previous video. F1 generation with Quadrifoliate/pentafoliate leaf is also noticed. This character has been transferred toF2 generation as you see in the present video taken on 01.12.10. The mutation created morphological change in plant with stable genetic change as you see it. Plant hybridization or breeding is not new. This type of inducing asexual (without chemical) mutation is new to the plant science. In this method morphological changes occur. The method may open new line of research in future. Additional Information: Previously I had send three Videos which were seen in paticipating list. Since the Video was taken on 01.12.2010 could not be sent. However if possible this may be included as it confirms the stability of genetic change.This is F2 generation.As this mutation is stable it can be tried in many crops.This will lead to a new branch of genetic science   Amazing Plants Kristine Hill and Zoë Randell General Summary of video content: A fun film by Kris Hill and Zoë Randell, highlighting why plants are so important. This film is designed to encourage non-scientists to think about plants and appreciate how essential plants are. Host Plant Recognition Rupesh Ram Kariyat General Summary of video content: As we all know, host plant recognition is one of the most important concepts in Plant –insect interactions. Most of the insect herbivores have some level of specificity and they have different methods to recognize their hosts. This video is made to help us understand about host plant recognition by herbivore insects and the methods employed by them Insects are everywhere and a major food source for insects are plants. Although plants are everywhere we really don’t see the same insects on all the plants. Although there are generalist insects that can feed on a variety of plants, many of the herbivores are host-host family specific, like the one we are discussing in the video today As a herbivorous insect, they are always baffled by this question, what should I eat, and how can I choose between my host plant and thousands of other plants in this big green world? Unlike insects most vertebrates have a highly evolved food recognition system where they use vision, touch, smell and taste to locate and access their food source, but for insects most of these senses are very limited, especially vision and touch. So they have to rely upon smell and taste to locate their host. Let us see if they can do this. In this video we will use the herbivore Manduca sexta caterpillar, whose host plants are plants in the family solanaceae, which include tobacco, tomato, egg plant, peppers, horsenettle etc to find out if a Manduca caterpillar will be able to distinguish between a host plant and a non host plant and then specifically choose to feed on the host plant? We will do a simple choice assay to see this. To do this experiment, we will use this design. We will have a petriplate with a filter paper placed inside it. We will cut out 2 leaf disks, one from a host plant and one from a non host plant. Then we will place a second instar Manduca on either above the disks or below the disks towards the perimeter of the plate and then will record their movement As the host plant, we will use tobacco, which is an important plant species in the family solanaceae. As our non host we will use squah plant in the family cucurbitaceae which is also a very important plant species.In the embedded real time video where the caterpillar is placed above the disks and you can clearly see that it only takes the caterpillars less than a minute to locate the host and start feeding. If you look closely you can see that the caterpillar is moving its head to both sides sensing the smell and then deciding to go to its actual host. So, basically due to the specialized recognition methods and specificity, specialist insects are able to compete with other insects and evolve. Thank you.   Fields of Study Karl Haro von Mogel General, Part of a Series Summary of video content: Have you ever eaten one of those small PureHeart seedless watermelons, and wondered who made it?

Pressure bomb (crpVideo)

This video is a visual 10 step instruction manual how to use a pressure bomb for measuring water pressure in the xylem of transpiring leaves. It is an entry for the www.ChloroFilms.org video competition. Water in the xylem is under negative pressure. This tension can be measured by a “pressure bomb”. Tension pressure in a non-transpiring leaf is “equivalent” to water potential of cells surrounding the xylem (mesophyll cells), because the xylem’s osmotic potential is negligible. A single leaf is sealed in the pressure chamber with the cut surface protruding through a rubber stopper. Pressure is applied to the shoot from a tank of compressed air (or nitrogen) until xylem sap appears at the cut ends of the xylem. The hydrostatic pressure inside the xylem elements is then identical to the applied external pressure. The amount of pressure that must be applied to force water out of the leaf cells into the xylem is regarded as equal to the xylem tension when the leaf was cut from the plant. This video

plant and ecosystem levels. Think of the amazing things that plants do. They capture sunlight, using it to yank electrons out of water and add them to CO2, thereby making the sugars which feed virtually all life on Earth. They weave sugars into strong cellulose nano-fibers and use them to strengthen their cell walls. Cotton fibers, lumber, paper and many other useful materials are made from plant cell walls. The next generation of biofuels will come from them too. Plants function as chemical factories, making wonderful substances, from turpentine, rubber and lacquer to caffeine, aspirin and anti-cancer agents. Peas, beans and related plants partner with special bacteria to chemically 'fix' nitrogen gas, marrying this inert gas to hydrogen and carbon to make the essential building blocks of proteins and DNA. Plant roots mine the soil for phosphate, iron and other minerals essential for life, in the process helping to convert barren rocks into a thriving underground ecosystem. They can remove toxic substances from the soil and from water. Plants sense light, gravity, friendly and unfriendly microbes and insects, and respond appropriately. They have complex means
