Uncovering the transcriptional regulatory network involved in boosting wheat regeneration and transformation
Xuemei Liu,Xiaomin Bie,Xuelei Lin,Menglu Li,Hongzhe Wang,Xiaoyu Zhang,Yiman Yang,Chunyan Zhang,Jian Zhang,Jun Xiao +9 more
TL;DR: It is demonstrated that the sequential expression of genes mediating cell fate transition during regeneration is induced by auxin, in coordination with changes in chromatin accessibility, H3K27me3 and H3k4me3 status, which contributes to regeneration in wheat.

Epigenetic perspectives on wheat speciation, adaptation, and development.
Abstract: Bread wheat (Triticum aestivum) has undergone a complex evolutionary history shaped by polyploidization, domestication, and adaptation. Recent advances in multiomics approaches have shed light on the role of epigenetic mechanisms, including DNA methylation, histone modification, chromatin accessibility, and noncoding RNAs, in regulating gene expression throughout these processes. Epigenomic reprogramming contributes to genome stability and subgenome differentiation and modulates key agronomic traits by influencing flowering time, environmental responses, and developmental programs. This review synthesizes current insights into epigenetic regulation of wheat speciation, adaptation, and development, highlighting their potential applications in crop improvement. A deeper understanding of these mechanisms will facilitate targeted breeding strategies leveraging epigenetic variations to enhance wheat resilience and productivity in the face of changing environments.
