JAG modulates sepal flatness by regulating cell growth direction, interacts with AS2, and is antagonized by TCP24.

Abstract excerpt

Flat plant organs are crucial for optimal organ functionality. Polarity establishment and growth coordination between tissues are key factors in maintaining organ flatness. Ectopic ASYMMETRIC LEAVES2 (AS2) expression in the as2-7D mutant has been shown to disrupt growth across cell layers, leading to epidermal buckling in sepals. However, the detailed molecular mechanism remains unclear. Here, we show that...
