Florigen Activation Complex Dynamics and SVP-Mediated Repression Orchestrate Temperature-Regulated Flowering in Saffron.

ABSTRACT: Saffron, a high-value spice cultivated worldwide for its therapeutic and culinary uses, is a sterile triploid species, rendering conventional breeding approaches ineffective. This limitation underscores the need for molecular and biotechnological strategies for its genetic improvement. Flowering, a key determinant of saffron yield, is strongly influenced by temperature; however, the genetic regulatory networks underlying this process remain poorly understood. Our study identifies key regulators of saffron's flowering, focusing on the Florigen Activation Complex (FAC) components: FLOWERING LOCUS T (FT), bZIP transcription factor-FD and TERMINAL FLOWER-1 (TFL-1) and demonstrates their temperature-dependent roles in floral regulation. Spatiotemporal expression analyses suggested that CsatFT3
