The transition from R6 (big seed) to R7 (mature seed) associated with significant down regulation of processes such as cyclin- dependent protein serine/threonine kinase activity, polysaccharide transport, unsaturated FA biosynthesis, translation elongation factor activity, very long-chain fatty acid-CoA ligase activity and protein polymerization.
In addition to those, in genotype 53, some additional processes like flavonoid biosynthesis, photorespiration, porins, and PEP transport were down regulated as well.
The processes that were up regulated in R7 included nutrient reservoir activity, galactose metabolic process, serine type endopeptidase inhibitor activity, and hormone mediated signaling pathways.
