Considering the expected genetic variability of elephant grass (Pennisetum purpureum), due to its cultivation in different continents, we characterized and estimated the genetic divergences between 46 accessions of elephant grass with different edaphoclimatic adaptations, using RAPD and ISSR markers. We evaluated, comparatively, the consistency of the information achieved with these markers. Twenty-six RAPD and 25 ISSR primers were employed. The RAPD markers produced 185 bands, 72% of which were polymorphic, with a mean of 5.11 polymorphic bands per primer. The 25 ISSR starters produced 216 bands; 76% were polymorphic, with a mean of 6.56 polymorphic bands per primer. The correlation between the genetic distances achieved by the RAPD and ISSR markers was 0.76, which is highly significant by the Mantel test. Based on UPGMA grouping, considering the point of sudden change, five and six groups were formed for the data from the RAPD and ISSR markers, respectively. These markers provided partially concordant groups, indicating that these techniques can provide consistent information and consequently could be used in studies of genetic diversity among accessions. |

A new pathogenic Colletotrichum species was isolated from chayote (Sicyos edulis) leaves and fruit presenting typical anthracnose symptoms from fields in Ibirité (Minas Gerais state) and Tijucas (Santa Catarina state), Brazil. The species Colletotrichum menezesiae sp. nov. is described and illustrated. Multilocus phylogenetic analyses based on combined ACT, GAPDH, nrITS and TUB2 partial sequences revealed that Colletotrichum isolates from chayote form a distinct clade within the C. orbiculare species complex. This clade does not contain the ex-type of any species previously described and is also recognized as an independent lineage according to the GCPSR criteria. |
