Recently, Su Shihao's team from the College of Agriculture at Sun Yat-sen University published a paper in Nature Communications, revealing a new mechanism regulating differential development along the floral organ proximal-distal axis.
Using the Lamiales species Torenia fournieri as a model system, the researchers found obvious differential pigmentation and epidermal cell morphology along the proximal-distal axis of its corolla tube. The team identified a BOP transcription factor, TfBOP2, which can form protein complexes with the ALOG family factor TfALOG3 to jointly regulate the development of the proximal region of Torenia corolla.
Through analyzing the functions of Arabidopsis BOP1/2, the researchers inferred that BOP factors regulating differential development along the floral organ proximal-distal axis may be conserved in angiosperms. This discovery reveals a new regulatory mechanism for axial patterning, contributing to our understanding of the evolution and diversification of floral organs in plants.
