Can Bacillus spp. Enhance K+ Uptake in Crop Species

Abstract

For all organisms potassium (K) acts as an essential cationic nutrient. In plants, K regulates growth and movement of various plant organs and plays a crucial role in biotic and abiotic stress tolerance mechanisms. The rhizospheric microorganisms play an important role in K biogeochemical cycling and may influence K + uptake in crop species by direct and indirect mechanisms. The present article's major emphasis is on the characterization of K-solubilizing bacteria (KSB) and their effect on K uptake, plant development, and growth. Moreover, under various environmental conditions, the importance of K in crop yield improvement and the concentration of K in various plant parts were also described, and the possible molecular mechanism behind this phenomenon will be elaborated.

“…The presence of microbial hubs in plant microbiome networks plays an important role between a plant and its microbial community [624] with key microbial metabolic processes related to plant nutrition in paper 1 [448]. The mechanism of action of Plant growth-promoting rhizobacteria (PGPR) in the biofertilizer applied to cassava cultivation (paper 1) can produce a complex blend of volatile substances, which are distinct between bacterial species and other closely related species [214,215,233] provides the cassava soil and microbiome engineering, Some of these bacterial volatiles can stimulate plant growth [464,516], suppress disease stimulating ISR [464] or antagonize phytopathogens [290,695], nematodes, or insects [84,87]. Soil resources can also be transferred by shared symbiotic fungi called common mycorrhizal networks (CMNs) affirmed by Simard et al, [555].…”
