Do Plants Have Hormones? You Betcha! Mary Williams
General Summary of video content: I'm writing a series of articles for Teaching Tools in Plant Biology, a new feature of the journal The Plant Cell. Our goal is to encourage students of all ages to get interested in studying plants. Just for fun I'm creating a series of short YouTube videos that use the images I've been creating for the teaching articles. I hope this video helps people see the connection between the hormones that convey information in our bodies and the hormones that have similar functions in plants. Additional Information: I particularly like this video because the growing boys at the beginning are my own children, cartoon version.
Landing Lights for Bumblebees Andrew Chapple
General Summary of video content: Gardeners could help maintain bumblebee populations by growing plants with red flowers or flowers with stripes along the veins, according to field observations of the common snapdragon, Antirrhinum majus, at the John Innes Centre in the UK. Students spent successive summers observing the foraging patterns of bumblebees on snapdragon plants. The students compared the number of visits by bumblebees to various snapdragon cultivars and the number of flowers visited per plant. Red flowers and those with venation patterning were visited significantly more frequently than white or pink. Bumblebees are the main pollinators for snapdragon because the weight of the bee is needed to open the closed flower. Pollinators learn and memorize floral signals, such as flower shape, scent, colour and patterns of pigmentation. They return to flowers from which they have previously found food. Simple changes due to single gene changes can have dramatic effects on which pollinators visit and how often. Collaborators from New Zealand also analysed how the stripy patterns are formed along the veins of the common snapdragon. They showed that two signals interact to create the stripes.
FAMILIA PINACEAE BRENDA YESENIA VELASCO MARTINEZ
General Summary of video content: amily Pinaceae in Chiapas, Mexico Pinaceae, the Pinaceae, are a family of Order Pinales. It is the largest family in species diversity, between 220-250, distributed in 11 genera and second largest (after Cupressaceae). Are trees can grow between 2 to 60 m, usually evergreen (Except larix and Pseudolarix), resin canals, monoecious, of monopodial branching. Mexico is one of the richest countries in Pinaceae, have now reported about 60 species, with a considerable number of varieties. In Chiapas, two genera are represented in this family: pine and abies, both with very specific characteristics, in the state, about 13.8% of its territory is covered by forests of pine and pine-oak. To chiapas, Farjon and Styles in 1997 reported 11 species of pine with two varieties of these species. This genus is characterized by often whorled branching and more or less regular.The cup may be pyramidal or rounded, and mature trees, broad and depressed.

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.

All Things Algae Terry Woodford-Thomas
Technica Summary of video content: The video discusses the diversity among algae in the world and their importance to life on Earth. 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

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? Have a look at the next installment of Fields of Study with Xingping Zhang, a commercial plant breeder who works on watermelons and other cucurbits. This video takes you to Khon Kaen, Thailand to a Syngenta breeding station where Xingping talks about how he became a plant breeder, and what you might want to know if you think this kind of career sounds exciting. Additional Information: Fields of Study What does that delicious sweet corn in the summertime, your front lawn, and the ethanol in your gas tank all have in common? They all come from plants. But perhaps more importantly, they come from plants that have been bred and selected from among thousands of others to become that one perfect produce in the supermarket aisle. In this series, accomplished plant breeders talk about what they do, and what makes it an exciting career for them.
Vermicompost and Pythium Suppression Allison Jack
General Summary of video content: Curious about biologically based suppression of plant diseases? Excess livestock manure can be recycled into a material farmers can use to prevent seedling damping off through the process of earthworm composting, or vermicomposting. This video explains how microbes present in vermicompost protect cucumber seeds from infection by the plant pathogen Pythium aphanidermatum. Animations and microscopy footage show seed colonizing bacteria from vermicompost interrupting the chemical signaling between the germinating seed and the pathogen's motile zoospores. This video is part of an ongoing disease suppressive vermicompost research project at Cornell University. Additional Information: Check out the full length video (10 min) at Cornell's vermicompost research outreach page: www.css.cornell.edu/cwmi/vermicompost.htm Grand prize winner of the 2010 American Phytopathological Society Office of Public Relations and Outreach video contest. www.youtube.com/user/plantdisease#p/u/34/60hmY4GLicU And a recent TV spot featuring project collaborators: www.innovationtrail.org/post/worm-power-high-tech-composting

Charlie Chaplin and The Mysterious Microscope Andrew Harrison
General Summary of video content: In this video we used a Charlie Chaplin "spoof" This video will demonstrate that differential centrifuge, microscopy and staining are three important tools for study of plant cells. 1. under low speed of differential centrifuge, we can separate whole cells from the cell homogenate; 2. microscopy can reveal details of the cellular structures. 3. different staining methods can help us identify different organelles present in the plant cells. We made pea cell homogenate by using a blender, and then we did low speed centrifuge to pellet the whole cells out. After re-suspending the pellet, we made three slides, one control (without any staining), one stained with methylene blue, and one stained with Lugol's iodine. Methylene blue will stain nuclei deep blue. Thus, under light microscope, we will find that the nuclei and amyloplasts will be revealed by different staining.
Seed Imbibition Robert Lewis Gerten
General Summary of video content: This movie shows the phenomenon of seed imbibition. This movie was produced in the Saint John's University/ College of Saint Benedict Biology Department
Self-Incompatibility John Leonard & Kevin Hart & Ning AJ Wang & Chris Natale
General Summary of video content: Self-Incompatibility (SI) is a self/non-self recognition mechanism that allows the pistil of flowering plants to distinguish between self (genetically related) and non-self (genetically unrelated) pollen to prevent inbreeding and promote out-crossing. We use Petunia inflata (a relative of garden petunia) as a model to study the SI mechanism possessed by three families of flowering plants.
Breathing Krystle Padilla
General Summary of video content: A dance parallel is used to show the concept that while guard cells are open, the plant is breathing, it is daytime and it is dry; while guard cells are closed, the plant is not breathing, it is nighttime and it has dew. The process from plant to microscope is shown so that viewers may know the origin of the microscope visuals.
