“…Sequencing the loci of CAL, ApMat and GS is necessary to be able to confirm certainly the identity of these isolates, as shown in Liu et al (2015). By standardizing genes used in this type of studies, a similar degree of discrimination and delineation can be achieved in each species complex, a principle proposed by Everett (2014).…”

“…This could be an evidence that it is difficult to exactly assign a correct specific species name to different isolates, compared to assigning it only to a species complex. The question can rise whether it isn't just the population variability that is described in a species complex (and not single species), making it possible to refute the super speciation of the Colletotrichum complexes that exists today (Everett 2014;Børve and Stensvand 2017).…”

Worldwide Colletotrichum spp. have been identified as a problem in the apple production. This is the first study executed and confirming the presence of Colletotrichum spp. causing the postharvest disease bitter rot on apple fruits in Belgium. The identification, genetic diversity of Colletotrichum isolates (present in Belgian apple orchards) their morphological traits and pathogenicity on two apple cultivars (cvs. Pinova and Nicoter) with a different level of susceptibility were studied. Based on sequence analysis of six different gene regions beta-tubuline (TUB2), histone H3 (HIS3), glyceraldehyde-3phosphate dehydrogenase (GAPDH), chitin synthase 1 gene (CHS-1), actin (ACT) and the Internal Transcriber Spacer (ITS) gene region, six different Colletotrichum spp., belonging to either the C. acutatum or C. gloeosporioides complexes, were isolated from twenty-one apple cultivars in three Belgian orchards: C. fioriniae, probably C. kahawae, C. salicis, C. rhombiforme, C. acutatum and C. godetiae. Colletotrichum godetiae was found to be the most present and pathogenic species in Belgian orchards. The species C. rhombiforme was found and identified on apple fruit for the first time. Reliable morphological discrimination between species, based on features such as in vitro growth rate, colony colour and spore measurements, is not possible. As such, molecular identification appears to outperform morphological analysis and was in this study the most ideal tool for identifying unknown isolates of Colletotrichum species. Inoculation assays on two apple cultivars revealed a significant difference in pathogenicity among isolates and among Colletotrichum species. The pathogenicity tests also showed that isolates coming from another host species, e.g. strawberry, are also pathogenic on apple fruits. Cultivar Pinova appeared to be more susceptible to bitter rot than cv. Nicoter. Given the difficulties with managing Colletotrichum infections, additional knowledge on the pathogen and the plant-pathogen interaction is essential for effective disease control.

“…настоящее время существует огромное количество научных трудов и материалов, посвященных грибным болезням сельско-хозяйственных и цветочно-декоративных растений, выращиваемых в про мышленных масштабах [17,20], в то время как проблеме грибных болезней субтропических и тропических растений в условиях закрытого грунта не уделяется должного внимания [13]. Особенно это проблема актуальна для ботанических садов, где содержится большое количество видов и сортов растений [10], многие из которых сильно страдают от разных фитопатогенных микроорганизмов, в частности, микромицетов [11][12]18].…”

Аннотация. В данной статье приведен видовой состав патогенных микромицетов рода Colletotrichum Corda тропических растений-интродуцентов закрытого грунта ЦБС НАН Азербайджана. В ходе проведенного исследования выявлено 8 патогенных анаморфных видов (Colletotrichum crassipes (Speg.) Arx, C. gloeosporioides (Penz.) Penz.&Sacc., C.destructivum O'Gara, C. cliviae Yan L. Yang, C. musae (Berk.&M.A. Curtis) Arx, C. orchidearum Allesch., C. roseolum Henn., C. orthianum Kostlan) рода Colletotrichum, относящихся к отделу Ascomycota, классу Sordariomycetes, подклассу Hypocreomycetidae, порядку Glomerellales и семейству Glomerellaceae. Установлено 25 таксонов питающих растений, на которых проходит рост и развитие выявленных фитопатогенных видов. Установлено, что обнаруженные патогенные микромицеты рода Colletotrichum являются возбудителями болезни-антракноза на вегетативных и генеративных органах тропических растений в закрытом грунте. Описаны морфология и особенности биологии микромицетов.
