Resumo: Anthracnose caused by Colletotrichum species is the most important disease of chayote in Brazil. In this study, Colletotrichum species associated with anthracnose on fruits and leaves of chayote, from various producing regions in Brazil, were collected and characterized by molecular, morphology and cultural methods. Neighbor-Joining analysis based on sequences of the β-tubulin genomic region (TUB2) of 75 Colletotrichum isolates were analyzed as a first measure of genetic diversity. A subset of 32 isolates were sequenced using the partial sequences of actin (ACT), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), calmodulin (CAL) genes and rDNA ITS (ITS) region. Maximum Likelihood (ML) was performed using the concatenated sequences. The multilocus sequence analysis, associated with phenotypic characteristics revealed four previously described species (Colletotrichum brevisporum, C. cliviae, C. fructicola and C. karstii) and two unidentified species, in eight morphotypes. All isolates selected to represent each haplotype, in pathogenicity test were able to induce typical symptoms of anthracnose in chayote but varied in their virulence . All these species are reported for the first time associated with chayote Brazil and worldwide. C. orbiculare is not the causal agent of anthracnose chayote in Brazil.

Neste estudo, espécies de Colletotrichum associadas à antracnose em frutos e folhas de chuchuzeiro, de algumas regiões produtoras no Brasil, foram coletados e caracterizados a partir de métodos moleculares, morfologia e características culturais. Análise de Neighbor-Joining baseadas em sequências da região genômica da β-tubulina (TUB2), de 75 isolados de Colletotrichum, foram analisadas como uma primeira medida de diversidade genética. Um subgrupo de 32 isolados foram sequenciados usando os genes parcial actina (ACT), gliceraldeído-3-fosfato-desidrogenase (GAPDH), parcial actina (ACT) calmodulina (CAL) e genes rDNA- região ITS (ITS). Máxima verossimilhança (ML) foi realizada utilizando as sequências concatenadas. A análise multilocus das sequências, juntamente com um exame dos caracteres fenotípicos, revelou quatro espécies descritas anteriormente (Colletotrichum brevisporum, C. cliviae, C. fructicola e C. karstii) e duas espécies desconhecidas em oito morfotipos. Todos os isolados selecionados para representar cada haplótipo, no teste de patogenicidade foram capazes de induzir sintomas típicos de antracnose em chuchuzeiro, entretanto com variação em sua virulência. Todas estas espécies são relatadas pela primeira vez em associação ao chuchuzeiro e no Brasil e no mundo. C. orbiculare não é o agente causal da antracnose em chuchuzeiro no Brasil.Submitted by Mario BC (mario@bc.ufrpe.br) on 2016-11-28T14:20:37Z No. of bitstreams: 1 Christiane Almeida da Costa.pdf: 1520147 bytes, checksum: 6d69c020c39cd94f4b4d123eff29fb58 (MD5)Made available in DSpace on 2016-11-28T14:20:37Z (GMT).
