The Arabidopsis transcription factor TCP4 controls seed size by repressing the MINI3-SHB1-IKU pathway.

The Plant cell - 16 Feb 2026

Abstract excerpt

As an important agronomic trait that directly determines grain yield, seed size is tightly controlled by the timing of endosperm cellularization and seed coat proliferation. However, the precise regulatory mechanisms that coordinate the two processes remain elusive. Here, we demonstrate that in Arabidopsis (Arabidopsis thaliana), CINCINNATA (CIN)-like TEOSINTE BRANCHED 1/CYCLOIDEA/PCF (TCP) transcription factors...
