Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...
Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat (Triticum aestivum L.) production in the United States. Studies were conducted to determine the outcrossing rate, competitive ability, and effectiveness of certain control practices on jointed goatgrass. A field study was conducted over two years at four locations...
In mature Arabidopsis seeds, the testa (seed coat) is no longer a living tissue. Thus,
major sites of gene expression in imbibed seeds are the internal living tissues such
as the embryo and the endosperm. To elucidate the molecular mechanisms of seed
germination, the gene regulation in these two tissues...
