Morocco as a possible domestication center for barley: biochemical and agromorphological evidence

Abstract: Summary. The disiribution of geneüc variants of a group of low molecular weight, chloroform-methanol soluble proteins (CM proteins), among Moroccan and non-Moroccan accessions of Hordeum sponianeum and among selections from several Moroccan landraces of H. vulgare and cultivars of the same species with widespread European origin, suggests that domestication of barley might have taken place in Morocco. An agromorphological characterization of the H. sponianeum accessions further supports this hypothesis. The po… Show more

“…Recently, the discovery of wild barley in Morocco has been reported (Molina-Cano and Conde, 1980;MolinaCano et al, 1982). This finding suggest that the area of North Africa may be possible center of origin for cultivated barley and that barley may be a multicentric crop, domesticated along the Mediterranean basin (Molina-Cano et al, 1987, 1999Moralejo et al, 1994). Taking this into account, barley landraces collected from Morocco may be rich source of new genes for resistance to powdery mildew due to their high degree of diversification resulting from the long coevolution with populations of pathogen.…”

“…Quite a number of researchers, among them Willcox (2005) Willcox (2005) for example, suggests that each cereal species was domesticated in a different place by virtue of its varying ecological preferences. Additional arguments are building on studies of individual crop species -for example, multiple, independent domestication events proposed for einkorn in the Karacada region, Turkey (Kilian et al, 2007); and for barley in the Near East (Ladizinsky, 1998b;Morrell and Clegg, 2007), Central Asia (Takahashi, 1955;Morrell and Clegg, 2007), Ethiopia (Bekele, 1983;Orabi et al, 2007), and Morocco (Molina-Cano et al, 1987;2005).…”

“…A wellstudied case of intra-chromosomal duplication is that affecting the Itrl locus in Hordeum vulgare and H. spontaneum. A single active Itrl gene is present in most H. vulgare cultivars, whereas a duplication of this locus exists in some H. vulgare cultivars and in most H. spontaneum accessions, and the duplication shows divergent phenotypes within the latter species leading both to active trypsin inhibitors or to pseudogenes (Molina-Cano et al, 1987;Royo et al, submitted;Salcedo et al, 1984;). As to the possible interchromosomal dispersal mechanism, it is to be noted that the Itrl gene has been shown to be located next to the long terminal repeat of the "copia-like" retro-transposon Bare-1, which suggests that transposition may have played a role in the dispersal of the members of this multigene family (Royo et ai, 1996) ii) The possible coevolution of the plant inhibitors and the insect enzymes is suggested indirectly by the available evidence.…”
