Original multidisciplinary research hereby clarifies the complex geodomestication pathways that generated the vast range of banana cultivars (cvs). Genetic analyses identify the wild ancestors of modern-day cvs and elucidate several key stages of domestication for different cv groups. Archaeology and linguistics shed light on the historical roles of people(More)
BACKGROUND AND AIMS The production of triploid banana and plantain (Musa spp.) cultivars with improved characteristics (e.g. greater disease resistance or higher yield), while still preserving the main features of current popular cultivars (e.g. taste and cooking quality), remains a major challenge for Musa breeders. In this regard, breeders require a sound(More)
Azorhizobium caulinodans strain ORS571 induces nitrogen-fixing nodules on roots and stem-located root primordia of Sesbania rostrata. Two essential Nod loci have been previously identified in the bacterial genome, one of which (Nod locus 1) shows weak homology with the common nodC gene of Rhizobium meliloti. Here we present the nucleotide sequence of this(More)
Tetraploid individuals of orchardgrass (Dactylis glomerata L. subsp. hispanica Roth.) sampled from a natural population were used to evaluate the correlation between both single and multilocus heterozygosity at 7 enzyme loci, and several quantitative traits (plant size at time of collection, leaf weight, and panicle number in experimental trials). Four(More)
Many banana cultivars (including the Plantain type) are triploid interspecific hybrids between Musa acuminata (A genome) and Musa balbisiana (B genome). M. balbisiana contains endogeneous Banana streak virus sequences (eBSVs) that can, in interspecific genome context, spontaneously release infectious viral genomes. We analyzed, a triploid progeny of 184(More)
