Using emmer wheat to discover genes involved in drought tolerance

Wheat is a major global crop, but its yields are severely compromised by drought, thus developing varieties with a higher drought tolerance is important. Emmer wheat (Triticum turgidum) is a wheat ancestor that contains more genetic diversity than cultivated varieties, so it can be used in genome wide…

Phenotypic and genomic changes during modern wheat breeding in China and the United States

Jianqing Niu et al. explore how modern breeding reshaped wheat phenotype and genome in China and the United States, which will facilitate breeding higher performance wheat in the future. https://doi.org/10.1093/plcell/koad229 By Jianqing Niu and Hong-Qing Ling from Hainan Yazhou Bay Seed Laboratory…

TaGSK3 regulates the Green Revolution Protein Rht-B1b to reduce wheat plant height

Dong, Li, et al. explore the mechanisms regulating a Green Revolution protein that acts to reduce plant height Huixue Dong1,2,3, Danping Li1,3, Ruizhen Yang1, Lichao Zhang1, Yunwei Zhang1, Xu Liu1, Xiuying Kong1,*, and Jiaqiang Sun1,* State Key Laboratory of Crop Gene Resources and Breeding,…

Circadian regulation of the transcriptome in a complex polyploid crop (PLoS Biol)

Circadian regulation fine-tunes patterns of gene expression in plants in changing environments and has been selected for during crop domestication. Many studies have been done on circadian gene expression in Arabidopsis, but far less is known about this regulation in hexaploid bread wheat, especially…

Engineering a wheat spike

Li et al. investigated genes regulating wheat spike development and found that SQUAMOSA and SVP genes control the development of normal spikes. Plant Cell. https://doi.org/10.1093/plcell/koab243 By Jorge Dubcovsky, Kun Li and Juan Manuel Debernardi, University of California, Davis, CA, USA Background:…

Misexpression of a MADS-box gene results in longer glumes and grains in wheat

Adamski et al. reveal that the expression of a MADS-box transcription factor is the basis for a grain phenotype observed in Polish wheat. Plant Cell https://doi.org/10.1093/plcell/koab119 By Cristobal Uauy and Nikolai M Adamski John Innes Centre, Norwich NR4 7UH, United Kingdom Background:…

Transcriptome Dynamics and Gene Activities during Embryo and Grain Development in Wheat

Xiang et al. elucidate transcriptome dynamics and gene activities during embryogenesis and grain development in modern wheat and its progenitors. Plant Cell https://doi.org/10.1105/tpc.19.00397.

Breeding improves wheat productivity under contrasting agrochemical input levels (Nature Biotech.)

Wheat breeding programs are releasing new cultivars almost every year for improved yield potential. But is this intensive breeding not compromising the plant performance under adverse environmental conditions? Voss-Fels et al. studied the elite cultivars of winter wheat released during the last 50 years,…
