摘要

粒重是小麦产量构成三要素之一,而籽粒大小与粒重高度相关。因此,开展籽粒大小相关的研究对小麦高产育种具有重要意义。小麦TaGS2基因正调控籽粒大小和粒重。为进一步探索该基因等位变异情况,本研究利用黄淮海麦区268个小麦品种,根据TaGS2三个同源基因的基因组DNA序列设计特异引物,利用PCR扩增技术对其进行了鉴定。结果发现在部分品种中TaGS2-2B基因组序列第四个外显子3002 bp位有“CTT”3个碱基的缺失,导致其编码蛋白第306位苯丙氨酸(F)缺失。分别将 TaGS2-2B基因无和有 “CTT”缺失的变异类型命名为TaGS2-2B-a 和TaGS2-2B-b。不同基因型小麦品种的籽粒性状比较分析发现,TaGS2-2B-a基因型品种的千粒重、粒长、粒宽、籽粒面积和籽粒周长均显著高于TaGS2-2B-b基因型品种。本研究结果为小麦品种千粒重的提高提供了一种优良基因型TaGS2-2B-a。

Abstract

Kernel weight is one of the three elements contributing to the wheat yield, and kernel size is highly correlated with kernel weight. Therefore, the study of kernel size has a great significance to improve the wheat yield. The TaGS2 gene positively regulates kernel size and kernel weight in wheat. In order to further explore allelic variation of TaGS2 gene in wheat, specific primers were designed to amplify the genomic DNA sequence of three TaGS2 homoeologues and identify the polymorphisms in 12 samples of 268 wheat cultivars from the Yellow and Huai wheat regions. A deletion of three nucleotides (CTT) at position 3,002 bp in the fourth exon of TaGS2-2B genomic DNA sequence was detected in some cultivars, resulting in a deletion of one phenylalanine (F) at the 306 position. Both alleles without and with the 3 bp deletion was designated as TaGS2-2B-a and TaGS2-2B-b, respectively. In wheat cultivars carrying TaGS2-2B-a allele, thousand-kernel weight, kernel length, kernel width, kernel area, and kernel circumference were significantly higher than those of wheat cultivars harboring TaGS2-2B-b allele. Collectively, this study provided a relatively superior allele (TaGS2-2B-a) with positive effects in increasing kernel weight in wheat cultivars.
