Insights into transcriptional characteristics and homoeolog expression bias of embryo and endosperm in developing grain through mRNA-Seq and Iso-Seq


ABSTRACT: To analyse the regulation of transcripts in grain embryo and endosperm during development, we performed RNA-Seq for wheat from 14 and 25 day post anthesis (DPA). And long-read sequencing for mixed whole grains from 14 and 25 DPA was employed to obtain full-length transcripts. A series of differentially expressed genes and tissues-specific genes of embryo and endosperm were identified. Moreover, 4351, 4641, 4516 and 4453 genes with A, B and D homoeoloci were detected in the four tissues. These provide specific gene pools of embryo and endosperm and homoeolog expression bias model in a large scale, which provides new insights into the molecular physiology of wheat.
