Genome-edited powdery mildew resistance in wheat without growth penalties

Shengnan Li et al.

Summary: Disruption of susceptibility genes in crops can confer disease resistance, but often leads to undesired effects. This study identifies a mutant wheat variety with a targeted deletion in a specific gene that retains crop growth and yields while conferring robust resistance to powdery mildew.

Rht24b, an ancient variation of TaGA2ox-A9, reduces plant height without yield penalty in wheat

Xiuling Tian et al.

Summary: The study identified the causal gene of Rht24 in wheat, revealing that the dwarfing allele Rht24b not only reduced plant height but also increased nitrogen use efficiency and photosynthetic rate without yield penalty. Originating in wild emmer, Rht24b has undergone both natural and artificial selection, being detected in over half of wild emmer and wheat accessions.

N-terminal truncatedRHT-1 proteins generated by translational reinitiation cause semi-dwarfing of wheat Green Revolution alleles

Karel Van de Velde et al.

Summary: The Green Revolution's unprecedented wheat yield increases were achieved through the introduction of Rht-B1b and Rht-D1b semi-dwarfing alleles, encoding N-terminal truncated proteins that cause dwarfism without affecting dormancy, through translational reinitiation. The study also demonstrated the degradation process of wild-type RHT-1 proteins in response to gibberellin in wheat organs, providing insights into the molecular mechanisms underlying the agronomic traits.

Optical maps refine the bread wheat Triticum aestivum cv. Chinese Spring genome assembly

Tingting Zhu et al.

Summary: This research successfully refined the genome sequence of bread wheat cv. Chinese Spring (CS), improving the v1.0 assembly by filling gaps and correcting the positions and orientations of some scaffolds. With increased contiguity, the numbers of transposable elements and intact TEs have increased, along with the high-confidence gene models mapped onto the new assembly. The reconciled assembly enhances the utility of the sequence for genetic mapping, comparative genomics, and studies on the biology of wheat.
