Título em inglês: Characterization of the genetic diversity of common beans by RAPD markers. |
Conteúdo: |
Marcadores RAPD (Random Amplified Polymorphic DNA) foram usados para avaliar a diversidade genética entre 19 cultivares de feijão (Phaseolus vulgaris L.). Dos cento e oito locos de RAPD obtidos de 15 primers decâmeros, 70 foram polimórficos. Para estimar a distância genética foi usado o coeficiente de similaridade de Jaccard e as análises de agrupamento foram feitas pelos métodos UPGMA e Tocher. As análises de agrupamento confirmaram a ampla diversidade genética existente entre germoplasmas tropicais de feijão, separando as cultivares em dois grupos principais, correspondendo aos centros de domesticação Andino (genótipos de sementes médias e grandes) e Mesoamericano (genótipos de sementes pequenas). No grupo Andino, a diversidade genética relativa foi maior do que no Mesoamericano. |

Maize anthracnose, caused by the ascomycete fungus Colletotrichum graminicola, is an important crop disease worldwide. Understanding the genetic diversity and mechanisms underlying genetic variation in pathogen populations is crucial to the development of effective control strategies. The genus Colletotrichum is largely recognized as asexual, but several species have been reported to have a sexual cycle. We employed a population genomics approach to investigate the genetic diversity and reproductive biology of C. graminicola isolates infecting maize. We sequenced 108 isolates of C. graminicola collected in 14 countries using restriction site-associated DNA sequencing (RAD-Seq) and whole-genome sequencing (WGS). Clustering analyses based on single-nucleotide polymorphisms showed populational differentiation at a global scale, with three genetic groups delimited by continental origin, corresponding to the isolates from South America, Europe, and North America, compatible with short-dispersal of the pathogen, and geographic subdivision. Intra and inter-continental migration was predicted between Europe and South America, likely associated with the movement of contaminated germplasm. Low clonality and evidence of genetic recombination were detected from the analysis of linkage disequilibrium and the pairwise homoplasy index (PHI) test for clonality. Although the sexual state of C. graminicola has only been reported in lab conditions, we showed strong evidence that genetic recombination have a great impact on C. graminicola population structure, in contrast to the traditional view of C. graminicola being mainly clonal.
