Patterns of domestication in the Ethiopian oil-seed crop noug (Guizotia abyssinica)
Noug (Guizotia abyssinica) is a semidomesticated oil-seed crop, which is primarily cultivated in Ethiopia. Unlike its closest crop relative, sunflower, noug has small seeds, small flowering heads, many branches, many flowering heads, and indeterminate flowering, and it shatters in the field. Here, we conducted common garden studies and microsatellite analyses of genetic variation to test whethe...
متن کاملIdentifying genomic regions under selection during the domestication of noug (Guizotia abyssinica)
Certain traits are selected for during the course of domestication. Evidence of positive selection manifests itself as reduced variation between particular loci in the domesticate relative to its wild progenitor (Volis 2008). I propose to look for evidence of such selective sweeps in the Ethiopian composite crop Guizotia abyssinica relative to its progenitor Guizotia scabra ssp. schimperii usin...
متن کاملExploration of the reproductive barrier between noug (Guizotia abyssinica) and its progenitor Guizotia scabra ssp. schimperi
Domestication can be used to study the formation of barriers to reproduction because much is known about the selective forces at work during the process of domestication as well as the general timeline under which it occurs. Studying domestication may reveal how barriers to reproduction arise quickly and may give insight into speciation under natural conditions. Barriers to reproduction are ver...
متن کاملFactors Affecting Oilseed Quality during Storage with Special Reference to Soybean (Glycine max) and Niger (Guizotia abyssinica) Seeds
Oilseeds and edible oils are two of the most sensitive essential commodities. Oilseeds are important sources of edible oils of nutritional, industrial, and pharmaceutical importance. Groundnut, mustard/rapeseed, sesame, safflower, linseed, niger seed, castor are the major traditionally cultivated oilseeds. Soybean and sunflower have gained high importance in recent years, while coconut is most ...
متن کاملContrasting Patterns in Crop Domestication and Domestication Rates: Recent Archaeobotanical Insights from the Old World
BACKGROUND Archaeobotany, the study of plant remains from sites of ancient human activity, provides data for studying the initial evolution of domesticated plants. An important background to this is defining the domestication syndrome, those traits by which domesticated plants differ from wild relatives. These traits include features that have been selected under the conditions of cultivation. ...
