“…Anthracnose refers to widespread plant diseases caused by the Colletotrichum species. These fungi can severely damage various vegetables, flowers, crops, and fruit trees (e.g., plant blight, fruit decay, and leaf spot disease), resulting in serious economic losses [ 1 , 2 ]. Pepper ( Capsicum annuum L.) is a popular solanaceous vegetable that is rich in ascorbic acid, zeaxanthin, capsaicin, lutein, and β-carotene, which has beneficial effects on humans [ 3 ].…”

Pepper (Capsicum annuum L.) is a herbaceous plant species in the family Solanaceae. Capsicum anthracnose is caused by the genus Colletotrichum. spp., which decreases pepper production by about 50% each year due to anthracnose. In this study, we evaluated the resistance of red ripe fruits from 17 pepper varieties against anthracnose fungus Colletotrichum capsici. We assessed the size of the lesion diameter and conducted significance analysis to identify the resistant variety of B158 and susceptible variety of B161. We selected a resistant cultivar B158 and a susceptible cultivar B161 of pepper and used a transcription to investigate the molecular mechanisms underlying the plant’s resistance to C. capsici, of which little is known. The inoculated fruit from these two varieties were used for the comparative transcription analysis, which revealed the anthracnose-induced differential transcription in the resistant and susceptible pepper samples. In the environment of an anthrax infection, we found that there were more differentially expressed genes in resistant varieties compared to susceptible varieties. Moreover, the response to stimulus and stress ability was stronger in the KANG. The transcription analysis revealed the activation of plant hormone signaling pathways, phenylpropanoid synthesis, and metabolic processes in the defense response of peppers against anthracnose. In addition, ARR-B, AP2-EREBP, bHLH, WRKY, and NAC are associated with disease resistance to anthracnose. Notably, WRKY and NAC were found to have a potentially positive regulatory role in the defense response against anthracnose. These findings contribute to a more comprehensive understanding of the resistance mechanisms of red pepper fruit to anthracnose infection, providing valuable molecular insights for further research on the resistance mechanisms and genetic regulations during this developmental stage of pepper.

“…Ginseng, Panax ginseng , is one of the most important medicinal herbs in Northeast China with high values in nutrition and medicine ( Kim et al., 2010 ; Liu et al., 2020 ). Ginseng is a perennial plant with a long cultivation period and is widely planted in China, Korea, and Japan ( Sun et al., 2018 ; Wang et al., 2018 ).…”

“…Because of its long life, P. ginseng now suffers from various biotic stresses with fungal diseases as one of the main sources ( Kim et al., 2019 ). There are many fungal diseases in ginseng fields including anthracnose, gray mold, Alternaria blight, damping-off, and root rot ( Kim et al., 2010 ; Choi et al., 2011 ; Gao et al., 2014 ; Guan et al., 2014 ; Liu et al., 2020 ; Chen et al., 2022 ; Lu et al., 2019 ). Among these, anthracnose is one of the most destructive diseases, causing ginseng seedling blight in nurseries and promoting ginseng leaf spots in permanent beds ( Choi et al., 2011 ; Chung and Bae, 1979 ).…”

“…Colletotrichum panacicola was reported as a major fungal pathogen causing ginseng anthracnose disease in Korea ( Choi et al., 2011 ). Recently, C. panacicola was confirmed in all provinces in Northeast China such as Jilin, Liaoning, and Heilongjiang ( Liu et al., 2020 ). The C. panacicola was able to infect both ginseng leaves and stems more aggressively than other species ( Liu et al., 2020 ).…”

Transcriptome and metabolite analyses indicated the underlying molecular responses of Asian ginseng (Panax ginseng) toward Colletotrichum panacicola infection

Panax ginseng Meyer is one of the most valuable plants and is widely used in China, while ginseng anthracnose is one of the most destructive diseases. Colletotrichum panacicola could infect ginseng leaves and stems and causes serious anthracnose disease, but its mechanism is still unknown. Here, transcriptome and metabolism analyses of the host leaves were conducted to investigate the ginseng defense response affected by C. panacicola. Upon C. panacicola infection, ginseng transcripts altered from 14 to 24 h, and the expression of many defense-related genes switched from induction to repression. Consequently, ginseng metabolites in the flavonoid pathway were changed. Particularly, C. panacicola repressed plant biosynthesis of the epicatechin and naringin while inducing plant biosynthesis of glycitin, vitexin/isovitexin, and luteolin-7-O-glucoside. This work indicates C. panacicola successful infection of P. ginseng by intervening in the transcripts of defense-related genes and manipulating the biosynthesis of secondary metabolites, which might have antifungal activities.

“…For different species, the growth rate of Colletotrichum differed on various media and pH (Liu et al, 2018). Liu et al (2020) found that both C. lineola and C. panacicola , which caused ginseng ( Panax ginseng ) anthracnose, had varying growth rate and colony characteristics on eight different types of media (PDA, SNA, Czea, Mea, PCA, V8, OA and AEA) and pH from 4 to 11. For C. gloeosporioides isolated from yam ( Dioscorea batatas Decne), and its optimal growth pH was 5 (Fu et al, 2014).…”

Zhi mu (Anemarrhena asphodeloides Bunge.) is an important medicinal plant in China, and its growth is greatly threatened by the fungal disease anthracnose, which can be caused by a number of species of Colletotrichum. Studying the phytopathogen and its sensitivities to fungicides will help to control anthracnose on zhi mu. Ten isolates of Colletotrichum were collected from zhi mu in Hebei, Anhui and Shanxi Provinces in China for this study. The isolates were identified as C. gloeosporioides, C. liriopes and C. spaethianum based on multi‐locus phylogenetic analyses, including ACT, CHS‐1, GADPH, HIS3 and ITS, micromorphological characteristics and the characteristics of colonies. Koch's postulates were confirmed by inoculating the leaves of zhi mu in vitro. The levels of virulence of 10 isolates varied significantly. Isolate YC‐1 was the most virulent, while BZ‐2 was the least virulent. The sensitivity of isolates YC‐1, BY‐1 and BY‐2 (C. spaethianum, C. gloeosporioides and C. liriopes respectively) to fungicides were examined. The EC50 values of BY‐1, BY‐2, and YC‐1 to tebuconazole, difenoconazole, prochloraz, fludioxonil, pyraclostrobin, carbendazim and azoxystrobin confirm that all of the isolates were markedly sensitive to the seven fungicides tested, strongly suggesting that these fungicides could be used to control anthracnose on zhi mu in the field.
