is a fungal pathogen with a broad range of hosts, which can cause diseases and pose a great threat to many crops. Fungal-specific ZnCys transcription factors (TFs) constitute a large family prevalent among plant pathogens. However, the function of ZnCys TFs remains largely unknown. In this study, we identified and characterized SsZNC1, a ZnCys TF in , which is involved in virulence, sclerotial development, and osmotic stress response. The expression of was significantly up-regulated in the early stages of infection on leaves. The target deletion of resulted in reduced virulence on and oilseed rape. In addition, sclerotial development ability and growth ability under hyperosmotic conditions of knockout transformants were reduced. A transcriptomic analysis unveiled its regulatory role in key cellular functions, including cellulose catabolic process, methyltransferase activity, and virulence, etc. Together, our results indicated that SsZNC1, a core regulatory gene involved in virulence, sclerotial development and stress response, provides new insight into the transcription regulation and pathogenesis of .

Sclerotia serve as survival structures for many plant pathogens, including Sclerotinia sclerotiorum, which causes Sclerotinia stem rot (SSR) in soybeans and leads to significant yield losses. While partially resistant soybean varieties are effective in reducing SSR incidence, the relationship between resistance and sclerotial production remains unclear. This study investigated the sclerotial production of two soybean recombinant inbred lines (RILs) with differential levels of SSR resistance under both greenhouse and field conditions.

Article Synopsis
  • - Sclerotinia sclerotiorum is a harmful fungus affecting many crops, and controlling it is difficult due to the absence of resistant plant varieties and its long-lasting sclerotia.
  • - Research identified a gene (SsMNO1) crucial for the fungus's growth and virulence, and applying RNA interference (RNAi) strategies targeting this gene successfully inhibited its development and reduced its harmful effects on plants.
  • - RNAi agents aimed at SsMNO1 could be a promising method for managing Sclerotinia diseases, demonstrating both effects on preventing sclerotial formation and decreasing hyphal virulence in affected crops.

Ciboria shiraiana is a necrotrophic fungus that causes mulberry sclerotinia disease resulting in huge economic losses in agriculture. During infection, the fungus uses immunity elicitors to induce plant tissue necrosis that could facilitate its colonization on plants. However, the key elicitors and immune mechanisms remain unclear in C.

Article Synopsis
  • This study investigates the role of the heat shock protein gene Hsp70 in sclerotial formation and pathogenicity using techniques like RT-PCR and qRT-PCR to analyze gene expression at various growth stages and under stress conditions.
  • Results indicated that Hsp70 expression was highest in sclerotia compared to hyphae, significantly affected by cAMP stress and temperatures, showing the gene's importance in thermal stability.
  • Silencing Hsp70 resulted in a strain that could not form sclerotia, leading to decreased pathogenicity and resistance to fungicides, suggesting Hsp70 is crucial for stress resistance in the organism studied.
