Article Synopsis
- Leaf size plays a crucial role in photosynthesis and biomass in barley, but its genetic control is not fully understood.
- A genome-wide association study identified the gene PHOTOPERIOD-H1 (Ppd-H1) as a key factor influencing both flowering time and leaf size in winter barley cultivars.
- The research revealed that variations in leaf growth duration and cell number, driven by Ppd-H1, affect leaf size, suggesting a connection between leaf development and flowering that optimizes resource use for seed production.
Timing of the floral transition and inflorescence development strongly affect yield in barley (Hordeum vulgare). Therefore, we examined the effects of daylength and the photoperiod response gene PHOTOPERIOD1 (Ppd-H1) on barley development and analyzed gene expression changes in the developing leaves and main shoot apices (MSAs) of barley by RNA sequencing. The daylength sensitivity of MSA development had two phases, floret primordia initiated under long and short days, whereas successful inflorescence development occurred only under long days.
