Abstract
Abstract Barley, Hordeum vulgare L., was first domesticated at about 8000 BCE. Throughout the domestication process, selection in the wild species resulted in the loss of seed shattering, minimization of seed dormancy, and an increase in both seed size and number. Three critical domestication traits were a non-brittle rachis, a six-rowed spike, and a naked caryopsis. After primary domestication, some adaptive traits subsequently developed, such as shortened seed dormancy and early flowering time, which are probably associated with genetic mutations affecting protein structure and function. Multiple genetic pathways formed a complex regulatory network due to interactions between the pathways. Recent studies on barley domestication genes have provided a framework for understanding how these traits evolved and have revealed that drastic changes in gene function occurred during domestication. In this paper, we review the current molecular insights into H. vulgare domestication and discuss the domestication genes that underlie morphological trait changes in the evolutionary history of barley.
期刊介绍:
Critical Reviews in Plant Sciences focuses on presenting in-depth and up-to-date reviews of timely and/or cutting-edge subjects in the broad discipline of plant science, ranging from molecular biology/biochemistry through the areas of cell biology, plant pathology and physiology, genetics, classical botany, and ecology, to practical agricultural applications. Articles in the journal provide an up-to-date literature base for researchers and students, pointing the way towards future research needs. The journal is also a significant source of credible, objective information to aid decision makers at all levels.
