OsCYCD7;1 rigidly determines guard mother cell division in rice.

The New phytologist - 1 Jun 2026

Abstract excerpt

Functional stomata depend on paired guard cells that arise from a single symmetric division of the guard mother cell (GMC). However, the mechanism governing this division in grasses with unique dumbbell-shaped guard cells remains poorly understood. Here, we identify OsCYCD7;1 as an essential component for GMC division in rice. OsCYCD7;1 was strictly confined to pre-divisional GMCs, and its knockout prevented GMC...
