Plant roots aid the growth and functions of several kinds microorganisms such as plant growth-promoting rhizobacteria, mycorrhizal fungi, endophytic bacteria, actinomycetes, nematodes, protozoans which may impart significant impacts on health growth. soil–microbe interaction is an intricate, continuous, dynamic process that occurs in a distinct zone known rhizosphere. Plants interact with these soil microbes variety ways, including competitive, exploitative, neutral, commensal, symbiotic relationships. Both types were found to have impact community diversity structure rhizosphere, or vice versa.

Heat Stress and Plant–Biotic Interactions: Advances and Perspectives

Plants, Journal Year: 2024, Volume and Issue: 13(15), P. 2022 - 2022

Published: July 23, 2024

Climate change presents numerous challenges for agriculture, including frequent events of plant abiotic stresses such as elevated temperatures that lead to heat stress (HS). As the primary driving factor climate change, HS threatens global food security and biodiversity. In recent years, have negatively impacted physiology, reducing plant's ability maintain disease resistance resulting in lower crop yields. Plants must adapt their priorities toward defense mechanisms tolerate challenging environments. Furthermore, selective breeding long-term domestication higher yields made varieties vulnerable multiple stressors, making them more susceptible events. Studies on predict concurrent biotic will become severe future, potentially occurring simultaneously or sequentially. While most studies focused singular effects systems examine how plants respond specific stresses, simultaneous occurrence pose a growing threat agricultural productivity. Few explored interactions between plant-biotic interactions. Here, we aim shed light physiological molecular (bacteria, fungi, oomycetes, nematodes, insect pests, pollinators, weedy species, parasitic plants), well combined impact growth We also advances designing developing various strategies address multi-stress scenarios related factors.

Regenerative agriculture aims to boost native biodiversity and ensure sustainable production. Plant Growth Promoting Bacteria (PGPB) enhance crop yield through improved nutrient use efficiency or stress tolerance. Utilizing synthetic bacterial communities (SynCom) tailored specific challenges holds promise for enhancing plant resilience. However, include designing microbial consortia selecting SynCom application techniques. This study tested four PGPB methods on tomato plants evaluate their effectiveness in promoting resistance recovery from short extreme heat waves. Non-invasive phenotyping techniques were used assess responses three delivery (watering, foliar spray, alginate spheres immobilization) under stress. Plants treated with the marine like leaf spraying encapsulation exhibited resilience terms of Kautsky curve intensity shape, indicating better photochemical apparatus function. These also facilitated post-stress recovery. Deep analysis revealed SynCom-induced improvements plant's apparatus, particularly PS II donor side. Moreover, it was possible observe that upon relief these two techniques, alongside inoculated throughout watering able recover profiles. Analysing Fv/Fm values, watering, beads spray can be considered heat-tolerant, a characteristic conserved sampling moments. Heat-wave exposure led an increase energy absorbed by non-inoculated as counteractive measure overcome low observed (low trapping transported fluxes). The reduction impact attributed SynCom's ACC-deaminase production, which lowered ethylene accumulation, growth photosynthetic efficiency. noted reduced dissipation relief, efficient mechanisms due application.
