摘要

Weed intrusion significantly impacts lentil productivity, necessitating effective management strategies. Imazethapyr (IM), a selective herbicide, controls weeds by inhibiting acetolactate synthase, a key enzyme in branched-chain amino acid biosynthesis. This study investigated the impact of IM application and weed infestation on proline metabolism in tolerant (LL1397 and LL1612) and susceptible (FLIP2004-7L and PL 07) lentil genotypes. The findings revealed tolerant genotypes exhibited higher ∆1-pyrroline-5-carboxylate synthetase (P5CS) activity along with enhanced ornithine aminotransferase (OAT) activity as compared to susceptible genotypes Additionally, a reduction in proline dehydrogenase (ProDH) activity contributed to proline homeostasis, facilitating stress recovery and supporting growth, grain filling, and seed development in tolerant genotypes under herbicide stress. This study provides the first comprehensive insight into the role of proline metabolism in herbicide tolerance, offering a potential target for enhancing stress tolerance in lentil breeding programs.
