Plant Growth Promoting Rhizobacteria (PGPR) Regulated Phyto and Microbial Beneficial Protein Interactions

Abstract

<jats:title>Abstract</jats:title><jats:p>Plant Growth Promoting Rhizobacteria (PGPR) influence plants’ physiological characteristics, metabolites, pathways and proteins via alteration of corresponding gene expression. In the current study, a total of 42 upregulated uncharacterized sorghum bicolor root proteins influenced by PGPR were subjected to different analyses: phylogenetic tree, protein functional network, sequences similarity network (SSN), Genome Neighborhood Network (GNN) and motif analysis. The screen for homologous bacterial proteins to uncover associated protein families and similar proteins in non-PGPRs was identified. The sorghum roots’ uncharacterized protein sequences analysis indicated the existence of two protein categories, the first being related to phytobeneficial protein family associated with DNA regulation such as Sulfatase, FGGY_C, Phosphodiesterase or stress tolerance such as HSP70. The second is associated with bacterial transcriptional regulators such as FtsZ, MreB_Mbl and DNA-binding transcriptional regulators, as well as the AcrR family, which existed in PGPR and non PGPR. Therefore, Plant Growth-Promoting Rhizobacteria (PGPR) regulated phytobeneficial traits through reciprocal protein stimulation via microbe plant interactions, both during and post colonization.</jats:p>

Plant Root Enhancement by Plant Growth Promoting Rhizobacteria

“…Phytobeneficial characteristics were modulated by reciprocal protein activation via microbe-plant interactions during and after colonization by PGPR. Furthermore, bacterial gene regulators linked to bacterial signaling, DNA binding transcriptional regulators, and cell proliferation were induced by plant root exudates [93]. Climate change has a significant impact on the efficiency of PGPR, yet unfavorable growing circumstances in the field are to be expected as part of the routine operation of agriculture [94].…”

Impact of Plant Growth Promoting Rhizobacteria in Restoring Soil and Crop Attributes

“…Pseudomonas sp. is also reported to regulate protein synthesis, seed germination, siderophore production and phyto-beneficial traits (Zhang et al, 2019, Dhawi, 2020. Previous studies have also revealed that combined inoculation of A. Brailense with Pseudomonas sp.…”

Plant growth promoting rhizobacteria (PGPR) and their eco-friendly strategies for plant growth regulation: a review

“…Some important traits sustain plants under biotic and abiotic types of stress (140). Advanced bioinformatic studies indicate reciprocal gene regulation between bacteria and their host plants during colonization and post colonization also (141). Phyto-beneficial proteins have been reported to induce in sorghum roots after PGPR inoculation (141).…”

Phyto-beneficial proteins have been reported to induce in sorghum roots after PGPR inoculation (141). Some phyto-beneficial proteins deal with DNA regulation including Phosphodiesterase, sulfatase, Carbohydrate kinases (FGGY_C) whereas some of these are stress relieving in nature such as HSP70 (141).…”
