Stomata are plant-specific epidermal structures that consist of paired guard cells surrounding a pore. The opening and closing of these micro-valves facilitate carbon dioxide uptake for photosynthesis and reduce excessive water loss in plants.

Recently, a research group led by Prof. Le Jie at the Institute of Botany of the Chinese Academy of Sciences (IBCAS) found a genetic suppressor of flp stomatal defects. They found that RPA2a, a core subunit of Replication Protein A (RPA) complexes, acted downstream from the core cell cycle genes of CDKB1 to ensure terminal division during stomatal development and the formation of paired guard cells to create functional stomata units.
