Plant height and heading date are important agronomic traits in wheat (Triticum aestivum L.) that affect final grain yield. In wheat, knowledge of pseudo-response regulator (PRR) genes on agronomic traits is limited.

Despite wheat being one of the main staple food crops, until recently, comprehensive analysis of its gene family has been limited due to the lack of complete and high-quality reference genomes. Here, using the latest reference genome, we identified 17 genes in the wheat D-genome donor .

Genes that contribute to two or more favourable traits with no penalty on yield are rarely reported, especially in wheat. Here, we describe the editing of a wheat auxin response factor TaARF12 by using CRISPR/Cas9 that rendered shorter plant height with larger spikes.

- Diversity surveys of germplasm can reveal valuable insights into improving crops, focusing on InDels in hexaploid common wheat, which are not well understood.
- A comprehensive map of 89,923 InDels was created from the exome sequencing of 262 wheat varieties, providing a foundation for further genetic analysis like GWAS.
- The study successfully linked specific InDels to important traits such as spike and awn length, suggesting these markers could be useful in future wheat breeding efforts.
Article Synopsis
- The study focuses on understanding the genetic basis of wheat spike architecture, which is important for grain development and yield improvement.
- The research identified a wheat mutant with shortened spikes and grains induced by Cobalt treatment and utilized a multi-omics approach, including Exome Capture Sequencing, to uncover two significant genomic deletion regions linked to spike length.
- Genes within these regions, particularly those related to the Brassinosteroid pathway, were found to be associated with longer spike phenotypes, providing valuable insights and resources for future wheat breeding and genetics studies.
Background: DNA binding with one finger (Dof) transcription factors play important roles in plant growth and abiotic stress responses. Although genome-wide identification and analysis of the DOF transcription factor family has been reported in other species, no relevant studies have emerged in wheat. The aim of this study was to investigate the evolutionary and functional characteristics associated with plant growth and abiotic stress responses by genome-wide analysis of the wheat Dof transcription factor gene family.
