POLYPLOIDY, DOMESTICATION, AND ABIOTIC STRESS IN WHEAT

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 现代面包小麦是一种六倍体，含有三个基因组：AA，BB和DD。 每个基因组有七个不同的染色体。 位于同一条染色体上但不同基因组的基因被称为直向同源基因。 我们感兴趣的是如何在非生物胁迫可能会影响选择的关键基因在人类利用小麦在驯化过程中。 我们正在研究的基因是ADP-葡萄糖焦磷酸化酶大亚基（AGP-L），淀粉合成酶II（SSII），颗粒结合淀粉合成酶（GBSS），它们参与淀粉生物合成途径，和高分子量麦谷蛋白，特别是Glu-1-1。 该项目的第一个目标是了解多倍体如何影响这些基因的表达和调节。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Modern bread wheat is a hexaploid that contains three genomes: AA, BB, and DD. Each genome has seven different chromosomes. Genes that are on the same chromosome but different genomes are known as orthologous genes. We are interested in how abiotic stress may have influenced selection on key genes in the human utilization of wheat during domestication. The genes we are studying are ADP-glucose pyrophosphorylase large subunit (AGP-L), starch synthase II (SSII), granule bound starch synthase (GBSS), which are involved in the starch biosynthesis pathway, and high molecular weight glutenins, specifically Glu-1-1. The first goal of this project is to understand how polyploidy may have influenced the expression and regulation of these genes.
