Role of plant secondary metabolites in defence and transcriptional regulation in response to biotic stress

Secondary metabolites in plants have been recognized as a novel basis of potential bio-pesticides, paving the way for their use in sustainable agriculture. Plant secondary metabolites have pivotal roles in plant-pathogen interactions. Some important secondary metabolites of plants are terpenoids, flavanols, flavones, etc., are stress-inducible phytochemicals playing an important role in plant immune response development. Pathogen enters into host cell, multiply and utilise the biological mechanism of plants, causing a hazard to world food assembly. Under stressed circumstances, plants evolve a powerful and intricate system of growth and defensive action. On the other hand, transcription factors (TFs) assist…
