Plant Growth Promoting Rhizobacteria in Plant Health: A Perspective Study of the Underground Interaction

Abstract

Plants are affected by various environmental stresses such as high or low temperatures, drought, and high salt levels, which can disrupt their normal cellular functioning and impact their growth and productivity. These stressors offer a major constraint to the morphological, physiological, and biochemical parameters; thereby attributing serious complications in the growth of crops such as rice, wheat, and corn. Considering the strategic and intricate association of soil microbiota, known as plant growth-promoting rhizobacteria (PGPR), with the plant roots, PGPR helps plants to adapt and survive under changing environmental conditions and become more resilient to stress. They aid in nutrient acquisition and regulation of water content in the soil and also play a role in regulating osmotic balance and ion homeostasis. Boosting key physiological processes, they contribute significantly to the alleviation of stress and promoting the growth and development of plants. This review examines the use of PGPR in increasing plant tolerance to different stresses, focusing on their impact on water uptake, nutrient acquisition, ion homeostasis, and osmotic balance, as well as their effects on crop yield and food security.

Synthesis of the First Representatives of new 3,3a‐Dihydro‐1H‐Imidazo[4′,5′:4,5]Imidazo[2,1‐b]thia(selena)zole Heterocyclic Systems with Fungicidal Activity

“…Plant infectious diseases severely decrease the yield of crops as well as their quality, leading to more than $220 billion losses annually in the global economy [1–6] . Worldwide analysis has shown that pathogenic fungi are one of the most common causes of these diseases, accounting for approximately 30 % of all cases [6,7] .…”

“…Plant infectious diseases severely decrease the yield of crops as well as their quality, leading to more than $220 billion losses annually in the global economy. [1][2][3][4][5][6] Worldwide analysis has shown that pathogenic fungi are one of the most common causes of these diseases, accounting for approximately 30 % of all cases. [6,7] The use of fungicides is an effective method for combating fungal diseases, but the widespread use of known chemical fungicides can lead to drug resistance in fungi, highlighting the need for the development of new scaffolds.…”

Impact of two Erwinia sp. on the response of diverse Pisum sativum genotypes under salt stress

“…Although P. sativum is recognized to be moderately tolerant to soil salinity (Shahid et al 2022 ), elevated salt levels in soil were reported to significantly affect its productivity (Noreen and Ashraf 2009 ). In previous few years, inoculation of plants with beneficial soil microbes, including plant growth-promoting bacteria (PGPB), has proven to be a useful approach to enhance sustainable agriculture in soils subjected to several abiotic stresses, including salinity (Bhat et al 2023 , 2020 ; Peng et al 2023 ; Mishra et al 2021 ). They can increment the germination of seeds as well as the leaf size, improve chlorophyll and protein amount, increase crop growth and yield, in addition to nutrient accessibility, and delay the senescence of leaves (Saghafi et al 2019 ).…”

Whole-Genome Sequence Insight into the Plant-Growth-Promoting Bacterium Priestia filamentosa Strain AZC66 Obtained from Zygophyllum coccineum Rhizosphere

“…A variety of microbial groups grow and interact with roots in the rhizosphere due to the presence of nutrients secreted by plant roots. Root exudates are a group of soluble organic substances synthesized and released by roots, including amino acids, sugars, growth factors, and enzymes [ 1 , 2 , 3 ]. These nutrients shape the abundance and composition of microbes around plant roots.…”
