Abstract excerpt

Stomatal opening facilitates CO2 uptake and causes water loss via transpiration. Compared with the considerable progress made toward understanding phototropin-mediated blue light (BL) signaling in guard cells, the significance of cryptochromes (CRYs) in stomatal opening and their downstream elements remain largely unknown. Here, we show that 3 homologous MYB transcription factor genes, namely MYB11, MYB12, and...
