(Submitter supplied) 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. more...

(Submitter supplied) Centromeres typically contain repeat sequences, but centromere function does not necessarily depend on these sequences. In aneuploid wheat (Triticum aestivum) and wheat distant hybridization offspring, we found functional centromeres with dramatic changes to centromeric retrotransposon of wheat (CRW) sequences. CRW sequences were greatly reduced in the ditelosomic lines 1BS, 5DS, 5DL, and a wheat-Thinopyrum elongatum addition line. more...

(Submitter supplied) Common wheat (T. aestivum) converged three subgenomes adapted to different environments. The combinatorial interaction between transcription factors (TFs) and regulatory elements (REs) defines a regulatory circuit that underlies subgenome convergence and divergence. Compared to the relatively conserved gene composition across subgenomes, the intergenic regions with abundant REs is drastically diversified by almost complete TE turnovers, raising major questions regarding how subgenome convergent and divergent regulation is encoded in the highly diversified intergenic regions, and the impact of TE evolution on regulatory conservation and innovation. more...

(Submitter supplied) In wheat, the main staple crop in many regions of the word, one major challenge is to improve the yield potential while maintaining the grain quality, which is mainly defined by its protein concentration and composition. To achieve this goal, it is essential to considerate the nitrogen (N) and sulfur (S) nutrition, which strongly influences the grain storage protein (GSP) composition. Nowadays, the limitation of nitrogen inputs and the sulfur deficiency recently observed in soils represent major difficulties to control the grain quality. more...
