Anthracnose caused by Colletotrichum spp. is an important disease of pepper (Capsicum annuum), affecting fruits and the overall yield worldwide. The disease was recently observed for the first time in Israel in the summer of 2020. In this study, morphology, phylogenetic analysis using glutamine synthase (gs) and the intergenic region between apn2 and Mat1-2 genes (ApMat) sequences, and pathogenicity assays were conducted to characterize and identify the Colletotrichum isolates retrieved from symptomatic pepper fruits. This is the first report of Colletotrichum aenigma and C. perseae as pathogens of pepper anthracnose in Israel.

炭疽菌引起的炭疽病。是辣椒 ( Capsicum annuum )的重要病害，影响全球果实和整体产量。该疾病是最近首次观察到在以色列的2020年夏季在这项研究中，形态，系统发育分析使用谷氨酰胺合成酶（GS）和之间的基因间区域APN2和MAT1 - 2个基因（ApMat）序列，和致病性测定进行了表征和鉴定从有症状的辣椒果实中提取的炭疽菌分离物。这是Colletotrichum aenigma和C. perseae的第一份报告 作为以色列辣椒炭疽病的病原体。
