The present work aimed to study the culturable diversity of psychrotolerant bacteria persistent in soil under overwintering conditions, evaluate their ability sustain plant growth and alleviate chilling stress tomato. Psychrotolerant were isolated from agricultural field samples colleced during winter then used alleviation tomato plants (Solanum lycopersicum cv Mill). Selective isolation after enrichment at 5°C yielded 40 bacterial isolates. Phylogenetic studies indicated distribution genera...
Arbuscular Mycorrhizal Fungi (AMF) play major roles in ecosystem functioning such as carbon sequestration, nutrient cycling, and plant growth promotion. It is important to know how this ecologically soil microbial player affected by abiotic factors particularly heavy metal metalloid (HMM). The objective of study was understand the impact HMM concentration on AMF abundance community structure contaminated sites South Korea. Soil samples were collected from vicinity an abandoned smelter...
A wide range of C3 and C4 plant species could acclimatize grow under the impact salinity stress. Symbiotic relationship between roots arbuscular mycorrhizal fungi (AMF) are widespread well known to ameliorate influence stress on agro-ecosystem. In present study, we sought understand phenomenon variability AMF symbiotic saline amelioration in plants. Thus, objective was compare varied plants conditions. To accomplish above mentioned objective, conducted a random effects models meta-analysis...
The rapid increase in soil salinization has impacted agricultural output and poses a threat to food security. There is an urgent need focus on improving fertility yield, both of which are severely influenced by abiotic variables such as salinity sodicity. Abiotic forces have rendered one-third the overall land unproductive. Microbes primary answer majority production’s above- below-ground problems. In stressful conditions, proper communication between plants beneficial microbes critical for...
The present study was aimed at using cellulolytic bacterium Enhydrobacter and fungi Aspergillus sp. for preparing compost from rice husk (RH). Further, the prepared tested their effect on blackgram growth promotion along with different levels of recommended dose fertilizer (RDF) in black soil (typic Haplustalf) red Rhodustalf) soil. results revealed that, inoculation lignocellulolytic fungus (LCF) @ 2% considered as most efficient method composting within a short period. Characterization...
Association between arbuscular mycorrhizal fungi (AMF) and bacteria has long been studied. However, the factors influencing their association in natural environment is still unknown. This study aimed to isolate associated with spore walls of AMF identify potential characters for association. Spores collected from coastal reclamation land were differentiated based on morphology identified by 18S rDNA sequencing as Funneliformis caledonium, Racocetra alborosea mosseae. Bacteria isolated after...
Soil microorganisms play a major role in improving soil fertility and plant health. Symbiotic arbuscular mycorrhizal fungi (AMF) form key component of the microbial populations. AMF mutualistic association with host exert positive influence on its growth nutrient uptake. The establishment symbioses can positively be influenced by promoting rhizobacteria through various mechanisms such as increased spore germination hyphal permeability roots. Though there are evidences that combined...
The occurrence and role of endophytic bacterial communities in banana under different field-grown conditions have not yet been explored. Hence, a survey was conducted five cultivars – Rasthali, Hill banana, Co1, Nattu Poovan Red for the assessment endophytes grown Tamil Nadu, Southern India. From 352 isolated, 17 were selected based on distinct morpho-physiological characters. isolates grouped into eight genera, which belong to phyla Actinobacteria, Firmicutes Proteobacteria, with remarkable...
Salinity is one of the major factors contributing to loss crop productivity and thereby impacting livelihood people in more than 100 countries world area land affected by salinity increasing day day. This will worsen due various such as drought that might result high soil salinity. Use plant growth promoting rhizobacteria promising eco-friendly strategies for stress management part sustainable agricultural practices. However, it requires selecting with good survivability adaptation salt...
The studies on the biocontrol potential of pink pigmented facultative methylotrophic (PPFM) bacteria other than genus Methylobacterium are scarce. In present study, we report three isolates; PPO-1, PPT-1, and PPB-1, respectively, identified as Delftia lacustris, Bacillus subtilis, cereus by 16S rRNA gene sequence analysis. Hemolytic activity was tested to investigate pathogenicity isolates plants humans, results indicates that PPB-1 not pathogenic strains. Under in vitro conditions, D....
This study aims to increase Bacillus and Streptomyces antagonistic activity against the root rot wilt diseases of pulses caused by Macrophomina phaseolina Fusarium oxysporum f. sp. udum, respectively. To action, subtilis BRBac4, siamensis BRBac21, cavourensis BRAcB10 were subjected random mutagenesis using varying doses gamma irradiation (0.5-3.0 kGy). Following irradiation, 250 bacterial colonies chosen at for each strain their effects pathogens evaluated in a plate assay. The ERIC, BOX,...
Phyllosphere methylotrophic bacteria from tomato leaves were isolated using selective Ammonia Mineral Salt (AMS) medium. Totally thirty two epiphytic bacterial isolates selected based on their colony morphology and distinct pigmentation. All the tested Gram negative, rod shaped positive for urease, catalase oxidase activities. The preliminary screening of five randomly strains under in vitro plant growth promoting characteristics evaluated beneficial effects early showed nitrogen fixation,...
