DESCRIPTION:Change notice: hybrid\n B-vitamins are organic micronutrients t
 hat play a vital role in cellular metabolism by providing enzyme cofactors
 . Most animals have lost the ability to synthesise these cofactors and obt
 ain them in their diet\, whereas plants can produce all their own compound
 s\, and indeed are the major source of them for human nutrition. The situa
 tion is more complex for microbes with both producers and requirers are fo
 und in different species. Intriguingly this is also the case for microalga
 e\, which despite their photosynthetic lifestyle are often auxotrophic for
  one or more B-vitamin. In particular more than 50% of microalgal species 
 require vitamin B12 (cobalamin)\, the cofactor for methionine synthase\, t
 he central enzyme of C1 metabolism\, essential for both DNA synthesis and 
 production of S-adenosyl-methionine (SAM) the universal methyl donor\, whi
 ch in turn is required for methylation marks in DNA and histones. Here I w
 ill describe our work on elucidating the molecular basis for B12-auxotroph
 y in microalgae\, how this impacts metabolism and gene expression\, and th
 e possible role of vitamin exchange in initiating and maintaining microbia
 l communities.\nSpeaker: Alison Smith
