“…C. gloeosporioides is found on a wide variety of fruit crops such as almond, avocado, apple, coffee, banana, guava, mango, and strawberry (Freeman et al, 2000;Sanders and Korsten, 2003;Xiao et al, 2004;Photita et al, 2005;Prihastuti et al, 2009). On the other hand, C. musae appears to be specific to Musa spp (Su et al., 2011). Although C. musae was not prevalent in the present study, several studies have shown that C. musae is the most common species associated with anthracnose of banana.…”

“…Generally, the six C. musae isolates fall within the description of morphological characteristics by Su et al (2011), except the colony color of several isolates in the present study was white to orangish with floccose aerial mycelium. However, according to the sequences of ITS regions and β-tubulin, only three isolates (BB9, BN27 and BN29) were identified as C. musae with 99-100% similarity.…”

“…Morphological identification of Colletotrichum isolates was performed using the species descriptions by Sutton and Waterston (1970), Mordue (1971), Cannon et al (2008), Prihastuti et al (2009), andSu et al (2011). The shapes and sizes of conidia were determined by measuring 40 random conidia under a light microscope (Olympus BX41 with Soft Imaging System).…”

ABSTRACT. Anthracnose caused by Colletotrichum species is a common postharvest disease of banana fruit. We investigated and identified Colletotrichum species associated with anthracnose in several local banana cultivars based on morphological characteristics and sequencing of ITS regions and of the β-tubulin gene. Thirty-eight Colletotrichum isolates were encountered in anthracnose lesions of five local banana cultivars, 'berangan', 'mas', 'awak', 'rastali', and 'nangka'. Based on morphological characteristics, 32 isolates were identified as Colletotrichum gloeosporioides and 6 isolates as C. musae. C. gloeosporioides isolates were divided into two morphotypes, with differences in colony color, shape of the conidia and growth rate. Based on ITS regions and β-tubulin sequences, 35 of the isolates were identified as C. gloeosporioides and only 3 isolates as C. musae; the percentage of similarity from BLAST ranged from 95-100% for ITS regions and 97-100% for β-tubulin. C. gloeosporioides isolates were more prevalent compared to C. musae. This is the first record of C. gloeosporioides associated with banana anthracnose in Malaysia. In a phylogenetic analysis of the combined dataset of ITS regions and β-tubulin using a maximum likelihood method, C. gloeosporioides and C. musae isolates were clearly separated into two groups. We concluded that C. gloeosporioides and C. musae isolates are associated with anthracnose in the local banana cultivars and that C. gloeosporioides is more prevalent than C. musae.

“…Os parâmetros das variáveis fisiológicas avaliadas neste trabalho estão de acordo com as observações já descritas por diversos autores para a espécie C. musae (PHOTITA et al, 2005;ZAKARIA et al, 2009;ABD-ELSALAM et al, 2010;SU et al, 2011). As médias obtidas com a taxa de crescimento micelial, além das características culturais que foram analisadas e agrupadas, estão apresentadas na Tabela 1.…”

“…No entanto, trabalhos recentes desenvolvidos com isolados de banana determinaram as características fenotípicas e moleculares classificando essa espécie como um grupo monofilético dentro do complexo "C. gloeosporioides" (PHOTITA et al, 2005;ZAKARIA et al, 2009;ABD-ELSALAM et al, 2010). Como o isolado da espécie-tipo descrita para C. musae foi perdido durante o processo de conservação no pericarpo de banana, um neótipo foi designado por Su et al (2011). Essa espécie apresenta alto grau de especificidade em relação ao gênero Musa (UDAYANGA et al, 2013).…”

RESUMO -Sessenta isolados de Colletotrichum oriundos de campos de produção de banana dos Municípios de Vicência, São Vicente Férrer e Machados, no Estado de Pernambuco, foram avaliados quanto a características morfológicas, moleculares, culturais, de virulência e de diversidade genética. Os isolados foram identificados como C. musae, tendo a maioria conídios retos, oblongos, com ápices arredondados. A taxa de crescimento micelial variou de 1,36 a 1,91 cm/dia. Foram encontrados três grupos de coloração para as colônias: branca, creme e salmão, enquanto a presença de setores variou de 0 a 8 por isolado e, na maioria dos isolados (73,3%), houve a presença de microescleródios. A diferença em virulência foi significativa para a área abaixo da curva de progresso da doença, indicando variabilidade entre os isolados. O dendrograma gerado pela análise UPGMA dos marcadores ISSR-PCR revelou a formação de três grupos pelo coeficiente de similaridade de Dice, os quais correspondem, na sua maioria, às três áreas amostradas. Termos para indexação: Musa sp., antracnose, doença pós-colheita, morfologia, ISSR-PCR. DIVERSITY GENOTYPIC AND PATHOGENIC OF Colletotrichum musae IN PERNAMBUCOABSTRACT -Sixty Colletotrichum isolates originating from fields producing banana in the municipalities of Vicência, São Vicente Férrer and Machados in the State of Pernambuco were evaluated for physiological, morphological, molecular, cultural, virulence and genetic diversity characteristics. The isolates were identified as C. musae, with most conidia, straight, oblong with rounded summits. The mycelial growth rate ranged from 1.36 to 1.91 cm / day. Three groups of staining for colonies were found: white, cream and salmon, while the presence of sectors ranged from 0 to 8 per isolate, and in most isolates (73.3%) there were the presence of microsclerotia. The difference in virulence was significant for the area under the disease progress curve, indicating variability among isolates. The dendrogram generated by UPGMA analysis of ISSR-PCR markers revealed the formation of three groups by Dice similarity coefficient which correspond mostly to the three sampled areas.
