OverviewAI-generated summary
Gulab Rangani's research focuses on understanding herbicide resistance mechanisms in weeds, particularly in crops such as amaranth and junglerice. His work investigates the genetic and molecular basis of resistance, with a specific emphasis on mutations within the protoporphyrinogen oxidase (PPO) enzyme. Rangani has published research detailing novel single-site mutations in PPO that confer resistance to PPO-inhibiting herbicides and has explored the co-occurrence of functional PPO2 mutations in resistant Palmer amaranth populations.
His research also examines resistance to other herbicides, like S-metolachlor in Palmer amaranth, and addresses high resistance to quinclorac in multiple-resistant Echinochloa colona, linking it to elevated stress tolerance gene expression and xenobiotic detoxification pathways. Rangani has investigated the rapid reduction of herbicide sensitivity in junglerice through recurrent selection with sublethal herbicide doses combined with drought or heat stress. His work contributes to the understanding of weed biology and the development of effective weed management strategies.
