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.

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.

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).

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. Deedra McClearn

Fatty Acid Synthesis in Plants Debbie Swarthout
Technical Summary of video content: The video clip uses a pedagogical style of multiple choice questioning to teach the basic steps about fatty acid synthesis in plants. 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.

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?
