The anthracnose disease caused by Colletotrichum species is well-known as a major plant pathogen that primarily causes fruit rot in pepper and reduces its marketability. Thirty-five isolates representing species of Colletotrichum were obtained from chili fruits showing anthracnose disease symptoms in Chungcheongnam-do and Chungcheongbuk-do, South Korea. These 35 isolates were characterized according to morphological characteristics and nucleotide sequence data of internal transcribed spacer, glyceraldehyde-3-phosphate-dehydrogenase, and β-tubulin. The combined dataset shows that all of these 35 isolates were identified as C. scovillei and morphological characteristics were directly correlated with the nucleotide sequence data. Notably, these isolates were recorded for the first time as the causes of anthracnose caused by C. scovillei on pepper in Korea. Forty cultivars were used to investigate the pathogenicity and to identify the possible source of resistance. The result reveals that all of chili cultivars used in this study are susceptible to C. scovillei.

“…This is the first expression analysis of C. scovillei infected fruit ripening in pepper to provide valuable information on molecular mechanisms. C. scovillei was first described in Thailand in 2008 30 , and was also previously reported in Japan, Brazil, China, Korea, and Malaysia [31][32][33][34][35][36][37][38] . C. scovillei is considered one of the most widespread and commonly reported Colletotrichum species causing anthracnose in chili through-out Southeast Asia and South America 3 .…”

Capsicum annuum is one of the most important horticultural crops worldwide. Anthracnose disease (Colletotrichum spp.) is a major constraint for chili production, causing substantial losses. Capsidiol is a sesquiterpene phytoalexin present in pepper fruits that can enhance plant resistance. The genetic mechanisms involved in capisidiol biosynthesis are still poorly understood. In this study, a 3′ RNA sequencing approach was used to develop the transcriptional profile dataset of C. annuum genes in unripe (Uf) and ripe fruits (Rf) in response to C. scovillei infection. Results showed 4,845 upregulated and 4,720 downregulated genes in UF, and 2,560 upregulated and 1,762 downregulated genes in RF under fungus inoculation. Four capsidiol-related genes were selected for RT-qPCR analysis, two 5-epiaristolochene synthase (CA12g05030, CA02g09520) and two 5-epi-aristolochene-1,3-dihydroxylase genes (CA12g05070, CA01g05990). CA12g05030 and CA01g05990 genes showed an early response to fungus infection in RF (24 h post-inoculation-HPI), being 68-fold and 53-fold more expressed at 96 HPI, respectively. In UF, all genes showed a late response, especially CA12g05030, which was 700-fold more expressed at 96 HPI compared to control plants. We are proving here the first high-throughput expression dataset of pepper fruits in response to anthracnose disease in order to contribute for future pepper breeding programs. Chili peppers originate from the Americas and they are among the oldest cultivated plants, dating from before 3400 BC. Capsicum annuum L. is the most commercially important species, due to its usefulness in the human diet, medicines, beverages, and as ornamentals. Pepper fruits have several nutraceutical benefits for human health, due to a variety of antioxidant, anti-inflammatory, antimicrobial, anti-carcinogenic, and cardio-protective properties 1. Anthracnose is caused by Colletotrichum spp., and represents the major disease of chili fruit worldwide, leading to significant postharvest yield loss and reducing marketability 2. Twenty-four Colletotrichum species have been identified as pathogens of chili anthracnose, with the three main pathogenic species being C. scovillei (previously identified as C. acutatum), C. truncatum (syn. C. capsici), and C. siamense (previously identified as C. gloeosporioides) 3 .

“…In addition to C. acutatum isolation, which was previously identified in studies in Vietnam 7,8 , different Colletotrichum species causing anthracnose disease in chili pepper in Vietnam, C. scovillei, was firstly identified in this study. This Colletotrichum species was previously reported to cause chili anthracnose disease in Japan, Brazil, China, and Korea 6,[19][20][21] . Recently, it was shown that in South Asia and South-East Asia, except Sri Lanka, C. scovillei was the prevalent anthracnose-causing pathogen and showed very high aggressiveness when infecting non-wounded fruits 22 .…”

Introduction: Colletotrichum species is responsible for anthracnose, a worldwide serious disease, causing an important loss in chili pepper production. Therefore, screening disease resistant and sensitive chili pepper cultivars in Vietnam is important not only for in-depth studies of disease resistance-associated molecular mechanisms but also for chili production improvement via molecular marker-assisted breeding in Vietnam. Methods: To this end, in this study, two Colletotrichum isolates were obtained from the infected fruits collected from chili pepper (Capsicum annuum) fields in Tra Vinh province. According to the morphology analysis and the sequencing results of the internal transcribed spacer (ITS) regions, these isolates were identified as C. scovillei and C. acutatum. In order to identify the anthracnose-resistant chili pepper cultivars, the pathogenicity test was conducted by infecting fully developed green fruits of eleven chili pepper cultivars with the two isolated Colletotrichum strains. Results: CN404 and HNCS were the two strongest anthracnose-resistant cultivars. Two chili pepper cultivars, TV3 and PN400, showed different resistance tendencies to each Colletotrichum isolates. Four different SSR molecular markers were used in this study to identify the potential molecular markers associated with anthracnose resistance traits in chili pepper cultivars. Among the four examined markers, HpmsE126 was detected in two anthracnose-resistant chili pepper cultivars, suggesting its close relation to the anthracnose resistance trait in chili pepper. Conclusion: Given that two of the three most anthracnose-resistant cultivars, CN404 and TV3, possess HpmsE126 marker, this marker can be used to detect anthracnose-resistant lines in chili pepper breeding in Vietnam.
