malfunction | isozymes CsBCAT2 and CsBCAT3 restore the growth of a bat1DELTA/bat2DELTA double knockout Saccharomyces cerevisiae strain, and isozymes CsBCAT3 and CsBCAT7, that show different substrate preferences, act in a reverse reaction. The transgenic approach demonstrates that the overexpression of the three CsBCATs results in early flowering phenotypes, which are associated with the upregulation of FLOWERING LOCUS T (FT) and SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1) in a manner in which they are dependent on GIGANTEA (GI)/CONSTANS (CO) and SHORT VEGETATIVE PHASE (SVP)/FLOWERING LOCUS C (FLC) modules. The overexpressed CsBCAT isozymes with BCAT enzymatic activities affect the flowering time in transgenic Arabidopsis thaliana | Cucumis sativus var. sativus |
physiological function | the BCAT enzymes catalyze the interconversion of BCAAs to the branched-chain keto acids (BCKAs). There is an interconnection between branched-chain amino acid transferases (BCAT) genes, that function in branched-chain amino acid (BCAA) metabolism, and the flowering time in plants.
