Molecular Regulation of Catechins Biosynthesis in Tea [Camellia Sinensis (L.) O. Kuntze]


Molecular Regulation of Catechins Biosynthesis in Tea [Camellia Sinensis (L.) O. Kuntze]

Arti Rani et al. Gene. .


Catechins are bioprospecting molecules present in tea and any effort towards metabolic engineering of this important moiety would require knowledge on gene regulation. These are synthesized through the activities of phenylpropanoid and flavonoid pathways. Expression regulation of various genes of these pathways namely phenylalanine ammonia-lyase (CsPAL), cinnamate 4-hydroxylase (CsC4H), p-coumarate:CoA ligase (Cs4CL), flavanone 3-hydroxylase (CsF3H), dihydroflavonol 4-reductase (CsDFR) and anthocyanidin reductase (CsANR) was accomplished previously. In depth analyses of the remaining genes namely, chalcone synthase (CsCHS), chalcone isomerase (CsCHI), flavonoid 3'5'-hydroxylase (CsF3'5'H) and anthocyanidin synthase (CsANS) were lacking. The objective of the work was to clone and analyze these genes so as to generate a comprehensive knowledge on the critical genes of catechins biosynthesis pathway. Gene expression analysis was carried out in response to leaf age and external cues (drought stress, abscisic acid, gibberellic acid treatments and wounding). A holistic analysis suggested that CsCHI, CsF3H, CsDFR, CsANS and CsANR were amongst the critical regulatory genes in regulating catechins content.
