My Favourite Plant - Nicotiana benthamiana w/ Joe McKenna

Nicotiana benthamiana, often called known as benth or benthi, is a close relative of tobacco indigenous to Australia. The plant was used by Australiians as a stimulant as it contains nicotine and other alkaloids. It's indigenous names are tjuntiwari and muntju. It was first collected by Benjamin Bynoe on a voyage of HMS Beagle in 1837. N. benthamiana has been used as a model organism in plant research - as the leaves are frail, they can be injured in experiments to study ethylene synthesis. Ethylene is a plant hormone which is secreted, among other situations, after injuries. Using gas chromatography, the quantity of ethylene emitted can be measured. Due to the large number of plant pathogens able to infect it, N. benthamiana is widely used in the field of plant virology. Speaker profile: Joe describes himself as a "cell biologist trying to figure out how plant cells organise themselves using a lot of photons and a few electrons". "I am a cell biologist and use microscopy to determine how plant cells organize themselves. In order to harness the potential of plants to tackle the grand challenge of food security, we must first understand how they function at the cellular level. The plant vacuole is a phenomenal organelle. It takes up most of the space in the plant cell and provides a resource efficient method of generating the morphological diversity we see between plant species. Moreover, seed plants contain a specialized vacuole, the protein storage vacuole (PSV). This vacuole is the main repository of protein in seed plants." Having completed his degree in Biological Sciences from the University of Birmingham in 2008, Joe went on to complete a Masters in Plant Molecular Biology & Biotechnology at Imperial College London where he went on to complete his PhD. He is a Fellow of the Royal Microscopical Society (FRMS) and a Member of the British Society of Cell Biology (BSCB).
