How did the domestication of Fertile Crescent grain crops increase their yields?
The origins of agriculture, 10 000 years ago, led to profound changes in the biology of plants exploited as grain crops, through the process of domestication. This special case of evolution under cultivation led to domesticated cereals and pulses requiring humans for their dispersal, but the accompanying mechanisms causing higher productivity in these plants remain unknown. The classical view o...
متن کاملThe complex origins of domesticated crops in the Fertile Crescent.
A combination of genetics and archaeology is revealing the complexity of the relationships between crop plants and their wild ancestors. Archaeobotanical studies are showing that acquisition of the full set of traits observed in domesticated cereals was a protracted process, intermediate stages being seen at early farming sites throughout the Fertile Crescent. New genetic data are confirming th...
متن کاملGenetic evidence for a second domestication of barley (Hordeum vulgare) east of the Fertile Crescent.
Cereal agriculture originated with the domestication of barley and early forms of wheat in the Fertile Crescent. There has long been speculation that barley was domesticated more than once. We use differences in haplotype frequency among geographic regions at multiple loci to infer at least two domestications of barley; one within the Fertile Crescent and a second 1,500-3,000 km farther east. T...
متن کاملForestry's fertile crescent: the application of biotechnology to forest trees.
Relative to crop plants, the domestication of forest trees is still in its infancy. For example, the domestication of many crop plants was initiated some 10,000 years ago in the so-called 'Fertile Crescent' of the Middle East. By contrast, the domestication of forest trees for the purposes of producing more fibre began in earnest in the last half century. The application of biotechnology to for...
متن کاملBiodiversity and Sustainable Agriculture in the Fertile Crescent
The Fertile Crescent is a high biodiversity region where most temperate-zone agricultural species originated and were first domesticated. A favorable environment, a special plant community, and an adaptive population combined to initiate the Neolithic—the New Stone Age—in the Fertile Crescent. However, over time, valuable plant genetic resources of the region are being eroded through degradatio...
