DESCRIPTION:C4 photosynthesis has evolved independently in over sixty line
 ages and in so doing repurposed existing enzymes to drive a carbon pump th
 at limits the oxygenation reaction of RuBisCO. Compared with the ancestral
  C3 pathway it can increase photosynthetic efficiency by up to 50%. This i
 ncreased photosynthetic capacity allows higher rates of growth as well as 
 increased water and nitrogen use efficiencies. In all cases\, C4 proteins 
 accumulate to levels matching those of the photosynthetic apparatus and to
  allow this gene expression is modified. To better understand this rewirin
 g of gene expression we undertook RNA- and DNaseI-SEQ on de-etiolating see
 dlings of C4 Gynandropsis gynandra which is sister to C3 Arabidopsis. In t
 his talk the data will be discussed from two perspectives. First\, a more 
 exploratory approach to decipher the mechanisms that underpin the dynamic 
 induction of C4 photosynthesis gene expression. Second\, a more targeted f
 unctional validation approach using two core C4 pathway genes as examples\
 , hunting down cis-elements and then the identification of trans-factors.\
