“…Colletotrichum isolates causing GLS may be directly associated with species that cause BR and belong to diff erent complexes of species that are closely related to each other. Therefore, understanding the environmental condi� ons necessary for epidemic development and the species of isolates causing GLS and BR are essen� al to defi ne disease management strategies, which may depend on the species involved (De Silva et al 2017;Moreira et al 2020b).…”

“…The temporal progress of GLS usually follows an exponen� al or logis� c growth (Hamada et al 2019;Moreira et al 2020b). The model that best describes the temporal progress of the disease in Paraná is the logis� c model with random eff ects, as it considers the variability observed between leaves of the same twig and between trees and suggests that the way in which GLS manifests depends on local characteris� cs such as plant nutri� on, soil con-di� ons, sun exposure, physiological aspects, among others (Moreira et al 2020b). In this model, the es-� mates of maximum GLS asymptote and infec� on rate are higher, which indicates that the disease is more aggressive than that considered by other models.…”

“…Peach anthracnose occurs in fruit and is considered a secondary disease in peach crops as it occurs only sporadically, mainly in warmer and humid years. However, it has become a growing problem for many commercial growers and epidemics are worrying technicians, especially in Brazilian states with warmer climates such as São Paulo and also in other countries such as the United States and South Korea (Hu et al 2015b;Lee et al 2020;Moreira et al 2020a).…”

Colletotrichum species infect temperate fruit trees and symptoms can occurin various parts of the plant such as twigs, leaves, fl owers, and fruits. The damage caused by these diseases is severe in Brazilian subtropical conditi ons, where a high primary inoculum potential is present. This review addresses e ological and epidemiological studies of Colletotrichum spp. in persimmon, apple, peach, and grapevine crops. General aspects of the management of the diseases under subtropical conditi ons are also discussed. Regarding etiology, new taxonomic classifications of species, brief history of nomenclature, phylogenetic studies for species identification and survey of species reported as causal agents of diseases were reviewed. Regarding epidemiology, favorable conditions for the pathogen and the stages of the disease cycles were addressed. For persimmon and apple crops, a more in-depth discussion about the diseases was held. Two disease cycles, in the form of illustrative fi gures were proposed: Colletotrichum spp. x persimmon and Colletotrichum spp. x apple tree. The cycles were based on literature and on epidemiological studies developed by our research group. The etiological and epidemiological studies reported here provide support for integrated management strategies for the diseases that are causing damage to these fruit trees in Brazil and worldwide

“…Apple Glomerella leaf spot (GLS) and apple bitter rot (ABR) are two devastating foliar and fruit diseases of apple, which are a serious threat to apple production worldwide [ 1 – 3 ]. GLS is an epidemic disease leading to early defoliation and small sunken lesions (1 to 3 mm) that rarely develop into a rot on fruit [ 1 , 4 ].…”

“…GLS was first reported in the southwestern USA by Taylor in 1971 [ 7 ] when the disease was named “necrotic leaf blotch”. Later, GLS was found in Brazil but it was also given another name as “Gala leaf spot”, and finally in the 1990s, Sutton and coworkers changed the disease name to the current one as “Glomerella leaf spot” [ 3 , 8 ]. In China, GLS was first reported in 2011 at Fengxian in Jiangsu province and has become a widespread disease in apple-producing areas, such as Shangdong, Hebei, Liaoning, and Gansu Provinces [ 1 , 9 ].…”

Comparative transcriptome analysis reveals significant differences in gene expression between pathogens of apple Glomerella leaf spot and apple bitter rot

Background Apple Glomerella leaf spot (GLS) and apple bitter rot (ABR) are two devastating foliar and fruit diseases on apples. The different symptoms of GLS and ABR could be related to different transcriptome patterns. Thus, the objectives of this study were to compare the transcriptome profiles of Colletotrichum gloeosporioides species complex isolates GC20190701, FL180903, and FL180906, the pathogen of GLS and ABR, and to evaluate the involvement of the genes on pathogenicity. Results A relatively large difference was discovered between the GLS-isolate GC20190701 and ABR-isolates FL180903, FL180906, and quite many differential expression genes associated with pathogenicity were revealed. The DEGs between the GLS- and ABR-isolate were significantly enriched in GO terms of secondary metabolites, however, the categories of degradation of various cell wall components did not. Many genes associated with secondary metabolism were revealed. A total of 17 Cytochrome P450s (CYP), 11 of which were up-regulated while six were down-regulated, and five up-regulated methyltransferase genes were discovered. The genes associated with the secretion of extracellular enzymes and melanin accumulation were up-regulated. Four genes associated with the degradation of the host cell wall, three genes involved in the degradation of cellulose, and one gene involved in the degradation of xylan were revealed and all up-regulated. In addition, genes involved in melanin syntheses, such as tyrosinase and glucosyltransferase, were highly up-regulated. Conclusions The penetration ability, pathogenicity of GLS-isolate was greater than that of ABR-isolate, which might indicate that GLS-isolate originated from ABR-isolates by mutation. These results contributed to highlighting the importance to investigate such DEGs between GLS- and ABR-isolate in depth.
