Bacillus altitudinis HNH7 and Bacillus velezensis HNH9 promote plant growth through upregulation of growth-promoting genes in upland cotton.

Aims: The potential of endophytic Bacillus strains to improve plant growth and yield was evaluated.

Methods And Results: Endophytic Bacillus altitudinis HNH7 and Bacillus velezensis HNH9 were evaluated for their growth-promoting traits. In an in vitro plate assay, HNH7 and HNH9 exhibited proteolytic, amylolytic, lipolytic and cellulolytic activity.

Novel Genetic Dysregulations and Oxidative Damage in Induced by Plant Defense Eliciting Psychrophilic TS1.

This study elaborates inter-kingdom signaling mechanisms, presenting a sustainable and eco-friendly approach to combat biotic as well as abiotic stress in wheat. is a devastating pathogen causing head and seedling blight in wheat, leading to huge yield and economic losses. Psychrophilic strain TS1 was found as a potential biocontrol agent for suppression of under low temperature by carrying out extensive biochemical and molecular studies in comparison with a temperate biocontrol model strain FZB42 at 15 and 25 °C.

Genomic Features and Molecular Function of a Novel Stress-Tolerant Strain Isolated from an Extreme Environment.

Due to its topographical position and climatic conditions, the Qinghai-Tibet Plateau possesses abundant microorganism resources. The extremophilic strain KKD1 isolated from Hoh Xil possesses strong stress tolerance, enabling it to propagate under high salinity (13%) and alkalinity (pH 10.0) conditions.

Nematicidal Volatiles from GBSC56 Promote Growth and Stimulate Induced Systemic Resistance in Tomato against .

volatiles to control plant nematodes is a topic of great interest among researchers due to its safe and environmentally friendly nature. strain GBSC56 isolated from the Tibet region of China showed high nematicidal activity against , with 90% mortality as compared with control in a partition plate experiment. Pure volatiles produced by GBSC56 were identified through gas chromatography and mass spectrometry (GC-MS).

First report of post-harvest Fusarium rot of mandarin Citrus reticulata cv. 'Kinnow' caused by Fusarium equiseti in Pakistan.

Citrus reticulata cv. 'Kinnow' mandarin is the most popular and widely grown fruit crop in Pakistan. During 2017, a survey was conducted to the local citrus fruit markets of Faisalabad, Pakistan.

Antagonistic Potential of Novel Endophytic Strains and Mediation of Plant Defense against Verticillium Wilt in Upland Cotton.

Verticillium wilt caused by is a threatening disease of cotton, causing economic loss worldwide. In this study, nine endophytic strains isolated from cotton roots exhibited inhibitory activity against strain VD-080 in a dual culture assay. HNH7 and HNH9 were chosen for further experiments based on their high antagonistic activity.

The Type III Accessory Protein HrpE of pv. Surpasses the Secretion Role, and Enhances Plant Resistance and Photosynthesis.

Many species of plant-pathogenic gram-negative bacteria deploy the type III (T3) secretion system to secrete virulence components, which are mostly characteristic of protein effectors targeting the cytosol of the plant cell following secretion. pv. (), a rice pathogen causing bacterial blight disease, uses the T3 accessory protein HrpE to assemble the pilus pathway, which in turn secretes transcription activator-like (TAL) effectors.

Suppression of by the Induction of Systemic Resistance and Regulation of Antioxidant Pathways in Tomato Using Fengycin Produced by FZB42.

Lipopeptides from species exhibit promising biological control activity against plant pathogens. This study aimed to explore the potential of purified fengycin to induce systemic resistance in tomato against . FZB42, its mutant AK1S, and their corresponding metabolites showed in vitro inhibition of mycelium.

Genetic Screening and Expression Analysis of Psychrophilic spp. Reveal Their Potential to Alleviate Cold Stress and Modulate Phytohormones in Wheat.

Abiotic stress in plants pose a major threat to cereal crop production worldwide and cold stress is also notorious for causing a decrease in plant growth and yield in wheat. The present study was designed to alleviate cold stress on plants by inoculating psychrophilic PGPR bacteria belonging to Bacillus genera isolated from extreme rhizospheric environments of Qinghai-Tibetan plateau. The genetic screening of psychrophilic spp.

Transcriptional Profiling of Diffusible Lipopeptides and Fungal Virulence Genes During EZ1509-Mediated Suppression of .

is a devastating necrotrophic pathogen that infects multiple crops, and its control is an unremitting challenge. In this work, we attempted to gain insights into the pivotal role of lipopeptides (LPs) in the antifungal activity of EZ1509. In a comparative study involving five strains, EZ1509 harboring four LPs biosynthetic genes (viz.

Fengycin Produced by FZB42 Inhibits Growth and Mycotoxins Biosynthesis.

is a notorious pathogen that causes Fusarium head blight (FHB) in cereal crops. It produces secondary metabolites, such as deoxynivalenol, diminishing grain quality and leading to lesser crop yield. Many strategies have been developed to combat this pathogenic fungus; however, considering the lack of resistant cultivars and likelihood of environmental hazards upon using chemical pesticides, efforts have shifted toward the biocontrol of plant diseases, which is a sustainable and eco-friendly approach.

Volatile Compounds of Endophytic Bacillus spp. have Biocontrol Activity Against Sclerotinia sclerotiorum.

To develop an effective biological agent to control Sclerotinia sclerotiorum, three endophytic Bacillus spp. strains with high antagonistic activity were isolated from maize seed and characterized. In vitro assays revealed that the Bacillus endophytes could produce volatile organic compounds (VOC) that reduced sclerotial production and inhibited mycelial growth of S.
