“…Bacillus vallismortis stain TU-Oraga21 produced surfactin and iturin A to inhibit spore germination of Magnaporthe oryzae , the causal agent of rice blast at the infection court and accumulated endogenous salicylic acid, phenolic compounds, and hydrogen peroxide (H 2 O 2 ) during the infection process to eliminates the pathogen [ 117 ]. Pseudomonas fluorescens SP007s enhanced immune of kale and soybean by accumulation of endogenous salicylic acid and phenolic compounds against Pectobacterium carotovorum , the causal agent of soft rot in kale [ 118 ] and Xanthomonas axonopodis pv. glycines , the causal agent of pustule disease in soybean [ 119 ].…”

Plant health is necessary for food security, which is a key determinant of secure and sustainable food production systems. Deficiency of soil nutrients and invasion of plant pathogens or insects are the main destroyers of the world’s food production. Synthetic fertilizers and chemical-based pesticides are frequently employed to combat the problems. However, these have negative impacts on microbial ecosystems and ecosystem functioning. Rhizosphere microorganisms have demonstrated their potency to improve or manage plant nutrients to encourage plant growth, resulting in increased yield and quality by converting organic and inorganic substances around the rhizosphere zone into available plant nutrients. Besides regulating nutrient availability and plant growth enhancement, rhizobacteria or fungi can restrict plant pathogens that cause disease by secreting inhibitory chemicals and boosting plant immunity to combat pests or pathogens. Thus, rhizosphere microorganisms are viewed as viable, alluring economic approaches for sustainable agriculture as biofertilizers and biopesticides. This review provides an overview of the role of rhizosphere microorganisms in soil nutrients and inducing of plant defenses. Moreover, a discussion is presented surrounding the recent consequences of employing these microorganisms and a sustainable strategy towards improving fertilization effectiveness, and encouraging stronger, more pest-resistant plants.

A bacterial pustule caused by Xanthomonas axonopodis pv. glycines (Xag) is one of the main diseases of soybeans in Thailand. Beneficial microbes crucial to sustainable plant production were examined in this study. Soybean plants were sprayed with Pseudomonas fluorescens SP007s strain three times before Xag infection. The results showed a significant reduction in bacterial pustule disease severity by up to 85%, increased leaf accumulation of salicylic acid with 134% during the infection process of Xag. Furthermore, the Xag population size in soybean leaves was reduced by priming with SP007s. The mechanism of SP007s in the chemical structure of mesophyll was characterized by using the synchrotron radiation-based Fourier transform infrared (SR-FTIR) analysis. The SR-FTIR spectral changes from the mesophyll showed higher integral area groups of polysaccharides (peak of 900–1,200 cm−1). These biochemical changes were involved with the primed resistance of the soybean plants against the bacterial pustule disease as well as the polysaccharide signals that were linked to hypersensitive responses leading to a rapid death of plant cells to effectively restrict the growth of pathogens at the infected site. Therefore, we consider that SP007s can be a promising biocontrol agent by activating immunity of soybean plants.

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