DESCRIPTION:During C4 photosynthesis\, CO2 is concentrated around RuBisCO 
 to reduce photorespiration. The reactions in this pathway are distributed 
 between mesophyll (M) and bundle sheath cells (BS). In C. gynandra\, the e
 xpression of a family of decarboxylases (NAD-ME 1 & 2 is regulated by a 24
 0 nucleotide sequence within the coding region. A deletion series was gene
 rated to search for regulatory elements. Two elements within the CDS are r
 equired for BS preferential expression. Equivalent fragments in CgNAD-ME2\
 , AtNAD-ME1 & 2 convey the same pattern of expression. By looking for this
  elements in other gene families we found that malate dehidrogenase (MDH) 
 is regulated by the same elements. We conclude that during evolution genes
  involved in the oxidoreductase activity sub-network were co-recruited to 
 the BS in C.gynandra.
