Summary: The study found that (E)-2-hexenal can enhance the assimilation of sulfate byBotrytis cinerea at low concentrations, leading to increased infection severity in tomato and strawberry fruits. The results suggest that sulfate assimilation is a key factor affecting B. cinerea infection, and it is proportional to the sulfur content in the fruits.

Summary: The study elucidated the molecular and metabolic regulation mechanisms of Lilium's defense response to Botrytis elliptica infection, highlighting the importance of the phenylpropanoid and flavonoid pathways. Network analysis identified key hub genes involved in the response to fungal infection, indicating the crucial roles of jasmonic acid, salicylic acid, brassinolide, and calcium ions in the defense response of Lilium.

Summary: Fusarium proliferatum is a common hemi-biotrophic pathogen that infects a wide range of host plants, leading to significant crop losses. In this study, the effects of selected plant metabolites on the metabolism of F. proliferatum were analyzed. The results showed that some metabolites promoted fungal growth while others inhibited it.

Summary: WRKY75 positively regulates plant defense responses against necrotrophic fungal pathogens by directly binding to the promoter of ORA59 and interacting with JASMONATE ZIM-domain proteins. This gene functions as a critical component of the JA-mediated signaling pathway in Arabidopsis.

Summary: In this study, researchers established an efficient regeneration system for Longya lily, a flower and vegetable plant in China with poor tolerance to Botrytis fungal disease. They optimized the induction of embryogenic callus, adventitious shoot, and rooting induction, and examined the factors influencing transformation. The results showed high rates of callus induction, shooting induction, and rooting, and a transformation rate of 65.56%, with the BjCHI1 promoter being expressed in transgenic calli. These findings can contribute to the development of transgenic Longya lily plants with improved resistance to B. cinerea.

Summary: Plant height in rice is an important trait, and this study identified multiple genes and genetic interactions involved in regulating this trait. The discovery of a structural variant in the SD1 gene and the identification of additional genes provide valuable resources for breeding semi-dwarf rice. These findings also contribute to our understanding of the genetic mechanisms underlying plant height regulation in rice.

Summary: Antimicrobial protein LsGRP1 protects Lilium from gray mold caused by Botrytis elliptica, but its nonantimicrobial region LsGRP1(N) promotes spore germination of the fungus. By testing the effects of LsGRP1(N), LsGRP1, and the combination of LsGRP1(N) and the antimicrobial region LsGRP1(C), it was found that LsGRP1(N) enhances the sensitivity of B. elliptica to LsGRP1(C) and suppresses disease development. LsGRP1(N) also reduces gene expression related to B. elliptica infection and increases host defense activity.

Summary: This study analyzed the transcriptomic changes in Lilium leaves after treatment with exogenous melatonin and infection with B. elliptica. The results showed that melatonin treatment caused differential expression of a large number of genes, mainly enriched in defense-related pathways such as plant-pathogen interactions, plant hormone signal transduction, and MAPK signaling pathways. The expression of genes related to the MAPK pathway was significantly different between melatonin-treated and control groups, suggesting the potential role of melatonin in Lilium disease resistance to B. elliptica.

Summary: Fusarium species are widespread fungi with both saprotrophic and pathogenic properties. They are also known for their ability to produce mycotoxins, which makes them highly damaging to plants. Molecular tools have been valuable in species identification and phylogeny studies of the Fusarium genus.

Summary: Proteases are important in plant defense systems, playing crucial roles in establishing hypersensitive responses, priming, signaling, and recognition events through complex proteolytic cascades. However, the contribution of proteases to pathogen defense in grapevine remains poorly understood.
