Rhizosphere microbes play critical roles for plant's growth and health. Among them, the beneficial rhizobacteria have potential to be developed as biofertilizer or bioinoculants sustaining agricultural development. The efficient rhizosphere colonization of these is a prerequisite exerting their plant functions, but colonizing process underlying mechanisms not been thoroughly reviewed, especially nonsymbiotic rhizobacteria. This review systematically analyzed root compared it with that symbiotic pathogenic bacteria. also highlighted approaches improve efficiency proposed study rhizobacterial from holistic perspective microbiome under more natural conditions.

The considerable loss of crop productivity each year due to plant disease or pathogen invasion during pre- post-harvest storage conditions is one the most severe challenges achieving goals food security for rising global population. Although chemical pesticides severally affect quality and health consumers, a large population relies on them management. But currently, endophytes have been considered suitable biocontrol agents better colonization acclimatization potential. However, very limited number used commercially as agents. Isolation their screening represent potential characteristics are challenging by different procedures. Through web search using keywords “endophytes agents” “biocontrol mechanism endophytes,” we succinctly summarised isolation strategies in vitro vivo methods endophytic present review. In this paper, mechanisms application management also discussed. Furthermore, registration regulatory covered.

Abstract The growth and productivity of maize are severely affected by soil salinity. crucial determinants for the future performance plants productive seed germination seedling establishment; however, both stages liable to For grain, is an economically significant crop sensitive abiotic stresses. However, little known about defense responses salinity-induced antioxidant oxidative stress in maize. In our work, commercially available variety Raka-Poshi was grown pots 30 days under greenhouse conditions. To evaluate salt-induced oxidative/antioxidant salt 0, 25, 50, 75, 100 150 mM concentrations, treatments were provided using sodium chloride (NaCl). All biochemical indices calculated all NaCl while drought induced up 50% irrigation water. After germination, leaves collected measurement lipid peroxidase or malondialdehyde (MDA), glutathione reductase (GR), guaiacol (GPOD), hydrogen peroxide (H 2 O ), superoxide dismutase (SOD), lipoxygenase (LOX), catalase (CAT), ascorbate (APOD) glutathione- S -transferase (GST). results revealed a 47% reduction have shown that successive increase concentrations caused production. With concentration stress, lower levels H , SOD, MDA detected leaves. regarding morphology seedlings indicated root length shoot applications root-to-shoot weights found be increased decreased conditions During gene expression analysis collectively indicate that, conditions, nine mentioned enzyme-related genes consistently downregulated.

In this study, 20-day-old soybean plants were watered with 100 mL of mM NaCl solution and sprayed silica nanoparticles (SiO2 NPs) or potassium silicate every 3 days over 15 days, a final dosage 12 mg SiO2 per plant. We assessed the alterations in plant's growth physiological traits, responses bacterial microbiome within leaf endosphere, rhizosphere, root endosphere. The result showed that type silicon did not significantly impact most plant parameters. However, communities endospheres had stronger response to NPs treatment, showing enrichment 24 13 microbial taxa, respectively, compared which led 9 8 taxonomic respectively. rhizosphere less sensitive NPs, enriching only 2 clades, clades enriched by treatment. Furthermore, treatment beneficial genera, such as Pseudomonas, Bacillus, Variovorax likely enhancing salinity stress resistance. These findings highlight potential for foliar application sustainable farming plant-microbe interactions improve tolerance.

The use of biological control agents is one the best strategies available to combat plant diseases in an ecofriendly manner. Biocontrol bacteria capable providing beneficial effect crop growth and health, have been developed for several decades. It highlights need a deeper understanding colonization mechanisms employed by biocontrol enhance their efficacy pathogen control. present review deals with in-depth steps involved host bacteria. process starts from root zone, where establish initial interactions plant’s system. Moving beyond roots, migrate colonize other organs, including stems, leaves, even flowers. Also, attempts explore facilitating bacterial movement within such as migrating through interconnected spaces vessels or apoplast, applying quorum sensing extracellular enzymes during what needed long-term association plant. impacts on microbial community dynamics, nutrient cycling, overall health are discussed, emphasizing intricate relationships between microbiome benefits above-ground parts, 40 confer. By unraveling these mechanisms, researchers can develop targeted enhancing efficiency effectiveness bacteria, leading more sustainability resilience.

Non-rhizobial endophytes (NREs) are active colonizers inhabiting the root nodules. Though their role in lentil agroecosystem is not well defined, here we observed that these NREs might promote growth of lentils, modulate rhizospheric community structure and could be used as promising organisms for optimal use rice fallow soil. from nodules lentils were isolated examined plant growth-promoting traits, exopolysaccharide (EPS) biofilm production, metabolites, presence nifH nifK elements. The greenhouse experiment with chosen NREs, i.e., Serratia plymuthica 33GS sp. R6 significantly increased germination rate, vigour index, development (in non-sterile soil) fresh weight (33GS 94%, 61% growth) length shoot 86%, 51.16%) chlorophyll levels when compared to uninoculated control. Scanning Electron Microscopy (SEM) revealed both isolates successfully colonize roots elicit hair growth. inoculation resulted specific changes exudation patterns. plants treatment stimulated triterpenes, fatty acids, methyl esters comparison plants, altering microbial structure. Proteobacteria dominated microbiota all treatments. Treatment or also enhanced relative abundance other favourable microbes, including Rhizobium, Mesorhizobium, Bradyrhizobium. correlation network analysis abundances numerous bacterial taxa, which cooperation each other, having a possible promotion. results indicate significant promoters, includes patterns, enhancement soil nutrient status modulation microbiota, suggesting prospects sustainable, bio-based agriculture.

Abstract YABBY gene family is a plant-specific transcription factor with DNA binding domain involved in various functions i.e. regulation of style, length flowers, and polarity development lateral organs flowering plants. Computational methods were utilized to identify members the family, Carrot ( Daucus carota ) ‘s genome as foundational reference. The structure genes, location chromosomes, protein motifs phylogenetic investigation, syntony transcriptomic analysis, miRNA targets analyzed unmask hidden structural functional characteristics Carrots . In following research, it has been concluded that 11 specific genes irregularly dispersed on all 9 chromosomes proteins assembled into five subgroups AtINO , AtCRC AtYAB5 AtAFO AtYAB2, which created well-known classification Arabidopsis wide ranges carrots due segmental duplication, was detected prevalent when equated tandem duplication. Transcriptomic analysis showed one DcYABBY highly expressed during anthocyanin pigmentation carrot taproots. cis-regulatory elements (CREs) unveiled particularly respond light, cell cycle regulation, drought induce ability, ABA hormone, seed, meristem expression. Furthermore, relative study among indicated 5 sub-families sharing common characteristics. comprehensive evaluation provides direction for cloning understanding their properties carrots.

The rhizosphere, as the "frontline" of plant life, connects roots, rhizosphere microorganisms, and surrounding soil, plays a crucial role in growth health, particularly sustainable agriculture. Despite well-established contribution plant-microbe interactions to specific molecular mechanisms remain insufficiently understood. This review aims summarize physiological adjustments signal modulation that both plants microorganisms undergo within this unique ecological niche ensure successful colonization. By analyzing key processes such chemotaxis, root attachment, immune evasion, biofilm formation, we uncover how precisely modulate exudates either recruit or repel thereby shaping their colonization patterns. These findings provide new insights into complexity suggest potential directions for future research
