TL;DR: In this article, the MADS-box gene family, a gene family which plays a crucial role in vegetative and flower development, was identified using Bayesian analysis to detect selection signatures.

TL;DR: The data suggest some introgression from the wild to the weedy population but nevertheless that the gene flow between the parapatric wild and domesticated populations is very low, which challenges the traditional view that regular hybridization between domesticated and wild pearl millets explains the abundance of these weedy plants despite farmers’ seed selection.

TL;DR: Results suggest that farmers’ management has globally preserved sorghum genetic diversity in Niger, which was submitted to recurrent drought period and to major social changes during these last decades.

TL;DR: Data suggest that the seed flow is preferentially from south to north, i.e. from an area with more favorable rainfall conditions, and the potential consequences for the genetic diversity and adaptation of northern pearl millet landraces are discussed.

TL;DR: Recurrent formation of tetraploids from different diploid progenitors across the distribution range of A. senegal in the Sudano-Sahelian zone is discussed.
