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

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,…

Rate of photosynthetic acclimation to fluctuating light varies widely among genotypes of wheat (bioRxiv)
The speed at which photosynthesis is induced during shade-sun transitions, such as sun-flecks, contributes towards determining crop yield. The speed of induction can be limited by the dynamics of stomatal and mesophyll conductance, deactivation rates of photoprotective mechanisms, the acclimation rate…
