Maize was domesticated from its wild ancestor, teosinte, in southern Mexico between ~6,250 and ~10,000 years ago. The domestication of maize resulted in an extensive phenotypic change in female inflorescence (ear) structures from teosinte. MADS-box genes encode transcription factors which are key regulators of plant inflorescence and flower development. We examined DNA sequence variation in 32 ...
domestication of animals has had some important effects on physiology, morphology, behavior and well-being of domesticated animals. conscious or goal directed selections on animals for increasing their productions has accelerated the rate of the changes, leading to some well-being defections. this paper notes some aspects of animal domestication in context of genetic science. then explains how ...
Many SNPs are predicted to encode deleterious amino acid variants. These slightly deleterious mutations can provide unique insights into population history, the dynamics of selection, and the genetic bases of phenotypes. This is especially true for domesticated species, where a history of bottlenecks and selection may affect the frequency of deleterious variants and signal a "cost of domesticat...
Using a whole-genome-sequencing approach to explore germplasm resources can serve as an important strategy for crop improvement, especially in investigating wild accessions that may contain useful genetic resources that have been lost during the domestication process. Here we sequence and assemble a draft genome of wild soybean and construct a recombinant inbred population for genotyping-by-seq...
Despite decades of research across multiple disciplines, the early history of horse domestication remains poorly understood. On the basis of current evidence from archaeology, mitochondrial DNA, and Y-chromosomal sequencing, a number of different domestication scenarios have been proposed, ranging from the spread of domestic horses out of a restricted primary area of domestication to the domest...
Domestication of cereal crops has provided a stable source of food for thousands of years. The extent to which lignocellulosic crops will contribute to the world's renewable energy depends largely on how the new crops will be domesticated. Growing miscanthus as biofuel feedstocks on marginal and degraded land in northern and northwestern China offers an example for developing theoretical framew...
