Sclerotinia sclerotiorum is a phytopathogenic fungus that causes wilting and white rot in several species such as strawberry. The overuse of agrochemicals has caused environmental pollution plant resistance to phytopathogens. Inoculation crops with beneficial microorganisms arbuscular mycorrhizae (AM), plant-growth-promoting rhizobacteria (PGPR), their metabolites considered an alternative agro...

Stem rot caused by Sclerotinia sclerotiorum in many important dicotyledonous crops, including oilseed rape (Brassica napus), is one of the most devastating fungal diseases and imposes huge yield loss each year worldwide. Currently, breeding for Sclerotinia resistance in B. napus, as in other crops, can only rely on germplasms with quantitative resistance genes. Thus, the identification of quant...

Fungal hyphae--and in some cases, spores--are multi-nucleate. During genetic transformation of these spores or mycelia, only one nucleus generally receives the transferred T-DNA generating heterokaryotic colonies. Characterization of genetic changes, such as the effects of gene disruption in the transformants, requires purified homokaryotic lines. Hyphal tip transfer has conventionally been use...

BACKGROUND Plants have evolved efficient mechanisms to combat pathogen attack. One of the earliest responses to attempted pathogen attack is the generation of oxidative burst that can trigger hypersensitive cell death. This is called the hypersensitive response (HR) and is considered to be a major element of plant disease resistance. The HR is thought to deprive the pathogens of a supply of foo...

Bacillus spp. are well known to protect plants from seed or soil-borne pathogens by the synthesis of various metabolites with antimicrobial activity, such as hy?drolytic enzymes and antibiotics. This study aimed select most effective a group ten antagonistic strains antifungal activity assay. were primarily isolated soil identified B. safensis, pumilus subtilis 16S rDNA sequencing. The four ana...

AIMS To evaluate the antagonistic activity of Fusarium oxysporum nonpathogenic fungal strain S6 against the phytopathogenic fungus Sclerotinia sclerotiorum and to identify the antifungal compounds involved. METHODS AND RESULTS The antagonistic activity of Fusarium oxysporum strain S6 was determined in vitro by dual cultures. The metabolite responsible for the activity was isolated by chromato...

Coniothyrium minitans is an important mycoparasite of Sclerotinia sclerotiorum. In addition, it also produces small amounts of antifungal substances. ZS-1TN1812, an abnormal mutant, was originally screened from a T-DNA insertional library. This mutant showed abnormal growth phenotype and could significantly inhibit the growth of S. sclerotiorum when dual-cultured on a PDA plate. When spraying t...

Abstract The article presents the research data on effect of Fusarium blight, Phoma rot, and Sclerotinia blight plant productivity winter spring rapeseed, brown mustard, white mustard. As a result studies, we found that (the pathogens are fungi genus Link) was most harmful for mustard – affection by it significantly decreased productivity. At 4 points degree plants, harmfulness disease reached ...
