Mechanism of oxalate decarboxylase Oxd_S12 from Bacillus velezensis BvZ45-1 in defence against cotton verticillium wilt.

Verticillium wilt, a soilborne vascular disease caused by Verticillium dahliae, strongly affects cotton yield and quality. In this study, an isolated rhizosphere bacterium, designated Bacillus velezensis BvZ45-1, exhibited >46% biocontrol efficacy against cotton verticillium wilt under greenhouse and field conditions. Moreover, through crude protein extraction and mass spectrometry analyses, we found many antifungal compounds present in the crude protein extract of BvZ45-1.

GhTLP1, a thaumatin-like protein 1, improves Verticillium wilt resistance in cotton via JA, ABA and MAPK signaling pathway-plant pathways.

Verticillium wilt of cotton is a very serious soil-borne disease and there is no effective control method. The mechanism of Gossypium hirsutum thaumatin-like protein 1(GhTLP1) in upland cotton regulating Verticillium wilt resistance has been an uncovered research approach. GhTLP1 is mainly localized in the cell wall.

Identification and characterization of the Bicupin domain family and functional analysis of GhBCD11 in response to verticillium wilt in cotton.

Bicupin domain protein (BCD) family, an important component of Cupin domain superfamily, plays important roles in oxalic acid (OA) degradation and stress responses in high plants. However, no studies have been reported on the Cupin domain family in cotton up till now. In our study, a total 110 proteins including Cupin domain were identified from the upland cotton (Gossypium hirsutum).

Flagellin C decreases the expression of the cation/proton exchanger 3 gene to promote calcium ion, hydrogen peroxide, and nitric oxide and synergistically regulate the resistance of cotton to Verticillium wilt.

To date, no ideal effective method for controlling Verticillium wilt in upland cotton () has been defined. The purpose of this study was to determine the effects and mechanism through which flagellin C () regulates the cation/proton exchanger 3 gene (), induces plant immunity, and increases resistance to Verticillium wilt. The FLiC gene was cloned from an endophytic bacterium () isolated from roots of the upland cotton cultivar Zhongmiansuo 41.

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.

Antifungal Activity of Chaetoviridin A from CEF-082 Metabolites Against in Cotton.

Cotton Verticillium wilt (CVW) is a severe soilborne disease caused by the pathogen , and it has a great impact on cotton production. Previous studies found that the biocontrol agent CEF-082 and its metabolic filtrate could reduce the incidence of CVW; however, the underlying mechanism remains unclear. The metabolic crude extract of CEF-082 increased the sensitivity of .

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.

Pectin lyase enhances cotton resistance to Verticillium wilt by inducing cell apoptosis of Verticillium dahliae.

Verticillium wilt caused by Verticillium dahliae Kleb. is a major disease in cotton. We found that pectin lyase can enhance cotton resistance to Verticillium wilt and induce cell apoptosis of V.

Transcriptome analysis reveals the defense mechanism of cotton against Verticillium dahliae in the presence of the biocontrol fungus Chaetomium globosum CEF-082.

Background: Verticillium wilt of cotton is a serious soil-borne disease that causes a substantial reduction in cotton yields. A previous study showed that the endophytic fungus Chaetomium globosum CEF-082 could control Verticillium wilt of cotton, and induce a defense response in cotton plants. However, the comprehensive molecular mechanism governing this response is not yet clear.

Anther response to high-temperature stress during development and pollen thermotolerance heterosis as revealed by pollen tube growth and in vitro pollen vigor analysis in upland cotton.

Pollen tube growth in styles was strongly inhibited by temperature above 35 °C, and the yield of cotton decreased because of the adverse effect of high temperatures during square development. High-temperature stress during flowering influences the square development of upland cotton (Gossypium hirsutum L.) and cotton yield.

The bacterial lipopeptide iturins induce Verticillium dahliae cell death by affecting fungal signalling pathways and mediate plant defence responses involved in pathogen-associated molecular pattern-triggered immunity.

Verticillium wilt in cotton caused by Verticillium dahliae is one of the most serious plant diseases worldwide. Because no known fungicides or cotton cultivars provide sufficient protection against this pathogen, V. dahliae causes major crop yield losses.

[Population dynamics and antagonism toward Fusarium oxysporium f. sp. Vasinfectum. and Verticillium dahliae Kleb of endophytic bacteria from cotton].

Objective: To explore population dynamics of endophytic bacteria and obtain antagonistic endophytic bacteria toward Verticillium dahliae Kleb (Vd), Fusarium oxysporium f. sp. Vasinfectum (Fov) from cotton.

Population dynamics and identification of endophytic bacteria antagonistic toward plant-pathogenic fungi in cotton root.

The antagonistic potentials of endophytic bacteria isolated from the roots of six cotton cultivars at different developmental stages were determined in vitro toward three pathogens: Verticillium dahliae Kleb V107 and V396 and Fusarium oxysporum f.sp. vasinfectum (F108).
