Roles of Arbuscular Mycorrhizal Fungi on Plant Growth and Performance: Importance in Biotic and Abiotic Stressed Regulation

Diversity, Journal Year: 2020, Volume and Issue: 12(10), P. 370 - 370

Published: Sept. 25, 2020

Arbuscular mycorrhizal fungi (AMF) establish symbiotic associations with most terrestrial plants. These soil microorganisms enhance the plant’s nutrient uptake by extending root absorbing area. In return, symbiont receives plant carbohydrates for completion of its life cycle. AMF also helps plants to cope biotic and abiotic stresses such as salinity, drought, extreme temperature, heavy metal, diseases, pathogens. For stresses, mechanisms adaptation these are generally linked increased hydromineral nutrition, ion selectivity, gene regulation, production osmolytes, synthesis phytohormones antioxidants. Regarding involved in pathogen resistance including competition colonization sites improvement defense system. Furthermore, have a positive impact on ecosystems. They improve quality aggregation, drive structure bacteria communities, ecosystem stability. Thus, colonized will use more compared without mycorrhizae. this review, we present contribution growth performance stressed environments.

Arbuscular mycorrhizal fungi (AMF) is among the most ubiquitous plant mutualists that enhance growth and yield by facilitating uptake of phosphorus water. The countless interactions occur in rhizosphere between plants its AMF symbionts are mediated through fungal metabolites ensure partner recognition, colonization, establishment symbiotic association. colonization reprogram metabolic pathways plants, resulting changes primary secondary metabolites, which focus this review. During initial plant–AMF interaction facilitated regulation signaling carotenoid pathways. After establishment, association influences metabolism plant, thus sharing photosynthates with AMF. carbon supply to leads transport a significant amount sugars roots, also alters tricarboxylic acid cycle. Apart from nutrient exchange, imparts abiotic stress tolerance host increasing abundance several metabolites. Although initially suppresses defense response host, it later primes for better against biotic stresses reprogramming biosynthesis Additionally, influence on translates enhanced phytochemical content upregulation phenylpropanoid pathway, improves quality products. These phytometabolome induced depends identity both species, could contribute differential outcome A understanding landscape shaped would enable us harness performance, particularly under non-optimal growing conditions.

The Plant Genome, Journal Year: 2022, Volume and Issue: 16(1)

Published: Nov. 10, 2022

Breeding crop plants with increased yield potential and improved tolerance to stressful environments is critical for global food security. Drought stress (DS) adversely affects agricultural productivity worldwide expected rise in the coming years. Therefore, it vital understand physiological, biochemical, molecular, ecological mechanisms associated DS. This review examines recent advances plant responses DS expand our understanding of DS-associated mechanisms. Suboptimal water sources affect growth yields through physical impairments, physiological disturbances, biochemical modifications, molecular adjustments. To control devastating effect plants, important its consequences, mechanisms, agronomic genetic basis sustainable production. In addition responses, we highlight several mitigation options such as omics approaches, transgenics breeding, genome editing, mechanical methods (foliar treatments, seed priming, conventional practices). Further, have also presented scope speed breeding platforms helping develop drought-smart future crops. short, recommend incorporating multi-omics, traditional strategies, cultivars achieve 'zero hunger' goal.
