PLANT BIOLOGY A Time to Grow, a Time to Crop

Barley is a very adaptable grain crop that can be grown from the Arctic Circle to subequatorial near-desert regions. Part of barley's success derives from its diverse strains, which have various responses to changes in photoperiod. Turner et al. have now identified the Ppd-H1 gene of barley and find that it participates in the coordinate regulation of flowering by circadian clocks and seasonal photoperiod. A spring variety of barley shows reduced photoperiod response caused by a mutation in this gene that delays its flowering. Instead, the plant accumulates the vegetative mass required to produce more grain.
