Background: Colletotrichum sublineola is the pathogenic fungus that causes sorghum anthracnose, which seriously threatens sorghum yield. Benzovindiflupyr is a succinate dehydrogenase inhibitor with good control effects on various crop diseases. However, the control of sorghum anthracnose by benzovindiflupyr and the risk of resistance to benzovindiflupyr in this pathogen are not well studied.

Fludioxonil is widely used to prevent and control gray mold due to its low toxicity and high efficiency; however, resistance caused by long-term use has become increasingly prominent. Therefore, exploring the resistance mechanism of fungicides provides a theoretical basis for delaying the occurrence of diseases and controlling gray mold.

Over- or constitutive activation of defences would negatively affect plant growth and development. Hence, the plant immune system is under tight positive and negative regulation.

Yet, the molecular basis of schizotrophic fungal responses to different plant hosts remains unexplored. Here, we observed a general increase in the gene expression of associated with pathogenicity in symptomatic rapeseed, including small protein secretion, appressorial formation, and oxalic acid toxin production.

Prochloraz and azoxystrobin belong to the groups of demethylation inhibitors and quinone outside inhibitors, respectively, and are commonly used for controlling this disease. In this study, we analyzed the sensitivities of 100 isolates from Yunnan, Sichuan, Chongqing, and Zhejiang in Southern China to prochloraz and azoxystrobin.

GPI-anchored proteins are widely distributed in fungal plant pathogens, but the specific roles of the GPI-anchored proteins in the pathogenicity of Sclerotinia sclerotiorum, a devastating necrotrophic plant pathogen with a worldwide distribution, remain largely unknown. This research addresses , which encodes an glycine- and serine-rich protein named SsGsr1 with an N-terminal secretory signal and a C-terminal GPI-anchor signal.

Understanding the genetic diversity of is essential for efficient disease control and breeding for disease resistance. However, little is known about the genetic variation of from different rice cultivars.

Studies of the genetic diversity, evolution, and pathogenicity of can provide more information for disease control and cultivar breeding. Contrary to previous studies on the genetic diversity of different geographical populations of , this study analyzed the genetic variation of from different panicles of the same rice cultivar in a field in Yunnan Province using single nucleotide polymorphism molecular markers.
