Persimmon (Diospyros kaki) anthracnose, predominantly caused by Colletotrichum horii, is a destructive disease of persimmon. Thus, the evaluation of resistance resources is imperative for persimmon breeding and resistant variety deployment. In this study, the isolate from persimmon branches was identified as C. horii by using molecular and morphological characteristics. A total of 142 varieties were tested for anthracnose disease response by inoculation with the conidial suspension of C. horii. A significant variability was observed among the studied accessions. Only two accessions, which had a hypersensitive reaction with a slight lesion at the infection site at 14 days post inoculation, were highly resistant to anthracnose. A total of 7 and 24 accessions exhibited resistant and susceptible responses, respectively, to anthracnose. A total of 109 varieties with the highest proportion (76.76%) of accessions showed high susceptibility to C. horii. A total of 43 persimmon main cultivars were selected for the re-evaluation of the resistance level by counting the natural disease incidence of branches and fruits that showed similar resistant response. Moreover, nine of highly resistant or resistant accessions possessed desirable agronomic characters, including high fruit weight and strong growth potential. These resistant accessions could be used in the breeding of anthracnose-resistant persimmon varieties.

“…The cultivation of chili pepper is frequently threatened by the attacks of various pathogens, especially the anthracnose pathogens of the Colletotrichum species. Colletotrichum contains a large number of species members that have been classified into several species complexes (Cannon et al, 2012;Talhinhas and Baroncelli, 2021) (Damm et al, 2012a(Damm et al, ,b, 2019Weir et al, 2012;De Silva et al, 2021;Talhinhas and Baroncelli, 2021). At least 28 species have been reported and most of them are from the acutatum, gloeosporioides, and truncatum complexes (Mongkolporn and Taylor, 2018;de Silva et al, 2019).…”

Comparative Genomics of Three Colletotrichum scovillei Strains and Genetic Analysis Revealed Genes Involved in Fungal Growth and Virulence on Chili Pepper

et al. 2022

Colletotrichum scovillei causes anthracnose of chili pepper in many countries. Three strains of this pathogen, Coll-524, Coll-153, and Coll-365, show varied virulence on chili pepper. Among the three strains, Coll-365 showed significant defects in growth and virulence. To decipher the genetic variations among these strains and identify genes contributing to growth and virulence, comparative genomic analysis and gene transformation to show gene function were applied in this study. Compared to Coll-524, Coll-153, and Coll-365 had numerous gene losses including 32 candidate effector genes that are mainly exist in acutatum species complex. A cluster of 14 genes in a 34-kb genomic fragment was lost in Coll-365. Through gene transformation, three genes in the 34-kb fragment were identified to have functions in growth and/or virulence of C. scovillei. CsPLAA encoding a phospholipase A2-activating protein enhanced the growth of Coll-365. A combination of CsPLAA with one transcription factor CsBZTF and one C6 zinc finger domain-containing protein CsCZCP was found to enhance the pathogenicity of Coll-365. Introduction of CsGIP, which encodes a hypothetical protein, into Coll-365 caused a reduction in the germination rate of Coll-365. In conclusion, the highest virulent strain Coll-524 had more genes and encoded more pathogenicity related proteins and transposable elements than the other two strains, which may contribute to the high virulence of Coll-524. In addition, the absence of the 34-kb fragment plays a critical role in the defects of growth and virulence of strain Coll-365.

“…However, recent taxonomic studies and the EPPO-Q-BANK database suggest that there are currently only about 257 accepted species. Colletotrichum species are distributed across 15 major monophyletic clades or species complexes: acutatum, agaves, boninense, caudatum, dematium, destructivum, dracaenophilum, gigasporum, gloeosporioides, graminicola, magnum, orbiculare, orchidearum, spaethianum and truncatum [7,8].…”

Colletotrichum Species Complexes Associated with Crops in Northern South America: A Review

et al. 2022

View full text Add to dashboard Cite

Colletotrichum genus comprises a high number of plant pathogens causing anthracnose disease in different tropical and non-tropical crops. We aimed to review northern South American studies in the online SCOPUS database to: create a taxonomically updated list of the species complexes found in the region, describe their most important phytopathological characteristics, revise the methods used in the region to control disease, and discuss the role of fungus as a plant endophyte. A total of 19 Colletotrichum species within five complexes—acutatum, boninense, gigasporum, gloeosporioides, and orbiculare—have been reported in northern South America. Few studies have been conducted, particularly in Peru and Ecuador, despite the diversity of Colletotrichum hosts cultivated in the region. Important information can be extracted from our review: species do not appear to show host specificity, although some isolates show host preferences, certain plant species can host several Colletotrichum species, some studies show the importance of using plant extracts to control the disease, but biological control using microorganisms is certainly an open area of research in the region. In northern South America, only a few hosts have been reported to harbor Colletotrichum as endophyte, and the potential of these endophytes as biological control agents has not yet been explored.
