油菜(Brassica napus L.)是中国食用植物油的主要来源,提高种子含油量是增加菜籽油供应最为有效的方法.本研究利用 4 个油菜自交系授粉后 25 d、35 d、45 d的种子转录组数据分析,筛选出 43 个与油脂合成相关基因,其中 33 个基因持续上调表达,10 个基因持续下调表达,主要基因包括BnLEC1、BnABI5、BnOLEO4 和BnOBAP1a等.同时,结合 50 份半冬性甘蓝型油菜重测序数据,检测到与含油量显著相关 3 个 SNP、9 个 SNP 分别定位到BnOBAP1a-A10 和BnABI5-A05,其中BnOBAP1a-A10_Hap1 对应材料含油量显著高于Hap2,BnABI5-A05_Hap1 对应材料含油量显著高于Hap3.此外,利用WGCNA构建基因共表达网络发现,BnOBAP1a...

Rapeseed(Brassica napus L.)is the main source of edible vegetable oil in China,and increasing seed oil content is the most effective way to increase the supply of rapeseed oil.In this study,43 genes related to lipid synthesis were selected by ana-lyzing the seed transcriptome data of 4 rapeseed inbred lines 25,35,and 45 days after pollination.Among them,33 genes were continuously up-expressed and 10 genes were continuously down-expressed from 25 to 45 days of seed development.The main genes included BnLEC1,BnABI5,BnOLEO4,and BnOBAP1a.At the same time,combined with the resequencing data of 50 s...
