Peppers are widely cultivated around the world, yet they suffer from infections caused by Phytophthora capsici fungi throughout year, which severely impacts their yield. The β-1,3-glucanase gene has been shown in previous studies to significantly enhance plants’ ability cope with both biotic and abiotic stresses, including fungal infections. However, its function peppers not reported. In this study, 80 CaBG genes were initially identified, before being filtered down 54 CaBGs peppers, analyses conducted on physicochemical properties, chromosomal localization, phylogenetic tree relationships, synteny, promoters, expression levels of BG family. results indicated that these located 12 chromosomes. Phylogenetic analysis classified into three subfamilies, α, β, γ, each own specific functions, γ subfamily associated disease resistance peppers. Synteny showed relatively conserved have undergone extensive whole-genome duplication events. Promoter induced plant hormones various external stressors. Transcriptomic RT-qPCR revealed CaBG7 CaBG12 activated following infection P. capsici, two markedly higher resistant plants compared susceptible ones. Based analysis, we propose may be key for chili This study provides a theoretical basis breeding capsici-resistant molecular methods.

Chili wilt is a significant challenge in producing jalapeño peppers, which has led to the implementation of strategies help counteract or combat microorganisms responsible for it. One these use biological control microorganisms, such as Trichoderma, fungus recognized natural enemy that cause chili wilt. Therefore, this study aimed isolate and identify Trichoderma species from soils roots different plants, evaluate their antagonism against Rhizoctonia solani, Phytophthora capsici, Fusarium sp. Due complexity identifying at level, performing multilocus phylogenetic analysis was necessary, using ITS, RPB2, TEF1 regions. The isolated were T. afroharzianum, lentiforme, rifaii, brevicompactum, arundinaceum, longibrachiatum. Subsequently, they used three tests (dual culture, non-volatile organic compounds, volatile compounds) phytopathogenic microorganisms. demonstrated isolates could inhibit mycelial growth all tested pathogens, obtaining best results with strains brevicompactum (19RCS), lentiforme (63DPS), longibrachiatum (71JES), rifaii (77JCR), afroharzianum (24RQS, 87CCS, 88CCS 17RCS). strain 17RCS.
