Loose-Knit Family: Tracing the Evolution of Actin Depolymerizing Factors that Sever or Join the Actin Cytoskeleton

IN BRIEF by Jennifer Lockhart jlockhart@aspb.org The interior of a plant cell is supported by the actin cytoskeleton, a complex network of yarn-like fibers whose form changes as the cell develops, grows, and divides. Actin fibers readily come apart (sever) and join back together, depending on the needs of the cell. This process is carefully […]

Jay Keasling. Engineering Microbes to Solve Global Challenges

Filmed for iBiology 2016 Talk Overview Dr. Jay Keasling discusses the promise of biological systems to create carbon-neutral products for a range of applications, including fuels, chemicals and drugs. Keasling discusses the application of these principles to the development of a microbial platform for the synthesis of the anti-malarial drug, artemisinic acid. This platform has […]

Alistair Fritter. People, plants and planet

Filmed at Gatsby Summer School, 2011 Abstract: Population issues are receiving renewed attention from both scientists and policy-makers and well-founded predictions of likely global population growth have given new urgency to concerns about food security and loss of ecosystem services.  Plant science has a central role to play in making it possible to feed the […]

Steve Long: Food, Feed and Fuel from Crops under Global Atmospheric Change. Could we have it all in 2030?

Filmed at the Gatsby Summer School, Leeds University, 2014 Abstract Demand for our major crops is expected to rise 30% by 2030, while we look increasingly to croplands for energy as well as food and feed. This is at a time when the rate of increase in yield seen over the past 60 years is […]

Giles Oldroyd. Engineering the nitrogen symbiosis for smallholder farmers in Africa

Filmed at the Gatsby Summer School, University of Cambridge 2015 Western agricultural systems are reliant on the application of inorganic nitrogen fertilisers to greatly enhance yield. However, production and application of nitrogen fertilisers account for a significant proportion of fossil fuel usage in food production and the major source of pollution from agriculture. Prof Giles […]

Beverley Glover. Flowering plant diversity: development, function and evolution

Filmed at the Gatby Summer School, University of York, 2013 http://www.tree.leeds.ac.uk/tree.2.0/view_lecture.php?permalink=MTA2Nw Abstract: The enormous species diversity of the flowering plants has puzzled evolutionary biologists since Darwin’s day. The rapid radiation of the flowering plants can be attributed at least in part to their recruitment of insects as vectors for their pollen, and the subsequent reproductive […]
