Multiple origins of the determinate growth habit in domesticated common bean (Phaseolus vulgaris).

ABSTRACT:

Background and aims

The actual number of domestications of a crop is one of the key questions in domestication studies. Answers to this question have generally been based on relationships between wild progenitors and domesticated descendants determined with anonymous molecular markers. In this study, this question was investigated by determining the number of instances a domestication phenotype had been selected in a crop species. One of the traits that appeared during domestication of common bean (Phaseolus vulgaris) is determinacy, in which stems end with a terminal inflorescence. It has been shown earlier that a homologue of the arabidopsis TFL1 gene - PvTFL1y - controls determinacy in a naturally occurring variation of common bean.
