Plants have evolved several adaptive strategies through physiological changes in response to herbivore attacks. Plant secondary metabolites (PSMs) are synthesized provide defensive functions and regulate defense signaling pathways safeguard plants against herbivores. Herbivore injury initiates complex reactions which ultimately lead synthesis accumulation of PSMs. The biosynthesis these is regulated by the interplay molecules comprising phytohormones. volatile released upon attack capable directly inducing or priming hormonal pathways. Secondary enable quickly detect attacks respond a timely way rapidly changing scenario pest environment. Several studies suggested that potential for adaptation and/or resistance insect herbivores limited. These cause direct toxicity pests, stimulate antixenosis mechanisms herbivores, and, recruiting natural enemies, indirectly protect plants. Herbivores adapt up/down regulation sensory genes, sequestration detoxification toxic metabolites. PSMs modulate multi-trophic interactions involving host plants, enemies pollinators. Although role plant-pollinator has been little explored, reports suggest both pollinators mutually benefited. Molecular insights into regulatory proteins genes involved will pave metabolic engineering biosynthetic pathway intermediates improving plant tolerance This review throws light on modulating interactions, contributing knowledge plant-herbivore their management an eco-friendly sustainable manner.

Secondary metabolites in plants have been recognized as a novel basis of potential bio-pesticides, paving the way for their use sustainable agriculture. Plant secondary pivotal roles plant-pathogen interactions. Some important are terpenoids, flavanols, flavones, etc., stress-inducible phytochemicals playing an role plant immune response development. Pathogen enters into host cell, multiply and utilise biological mechanism plants, causing hazard to world food assembly. Under stressed circumstances, evolve powerful intricate system growth defensive action. On other hand, transcription factors (TFs) assist counter adverse environments by acting mediators stress signal regulating stress-responsive gene expression. The transcriptional post-transcriptional manipulation is capable aid molecular breeding genetic modification meant improved metabolite synthesis. Although presence numerous has established life, very slight known about interaction with pathogens specific mechanisms involved leading immunity. Chemical pesticides wreaking havoc on our environment. As consequence, environmental-friendly alternatives disease management, like plant-based metabolites, should be explored.

Crops aimed at feeding an exponentially growing population are often exposed to a variety of harsh environmental factors. Although plants have evolved ways adjusting their metabolism and some also been engineered tolerate stressful environments, there is still shortage food supply. An alternative approach explore the possibility using rhizosphere microorganisms in mitigation abiotic stress hopefully improve production. Several studies shown that rhizobacteria mycorrhizae organisms can help tolerance by enhancing plant growth; stimulating production phytohormones, siderophores, solubilizing phosphates; lowering ethylene levels; upregulating expression dehydration response antioxidant genes. This article shows secretion secondary metabolites as additional mechanism employed against stress. The understanding these mechanisms will efficacy plant-growth-promoting microorganisms.

Abstract Climate change is predicted to increase the frequency and intensity of abiotic stress combinations that negatively impact plants pose a serious threat crop yield food supply. Plants respond episodes combination by activating specific physiological molecular responses, as well adjusting different metabolic pathways, mitigate negative effects on plant growth, development, reproduction. synthesize wide range metabolites regulate many aspects growth responses stress. Although individual stresses have been studied extensively in species, recent efforts directed at understanding occur when factors are combined. In this review we examine studies metabolomic changes under suggest new avenues for development combination-resilient crops based breeding targets.
