Abstract excerpt

BACKGROUND: Dirigent (DIR) proteins mediate regioselectivity and stereoselectivity during lignan biosynthesis and are also involved in lignin, gossypol and pterocarpan biosynthesis. This gene family plays a vital role in enhancing stress resistance and in secondary cell-wall development, but systematical understanding is lacking in cotton. RESULTS: In this study, 107 GbDIRs and 107 GhDIRs were identified in...
