Beyond the CO-FT regulatory module: E1 and PHYA emerge as players in photoperiodic regulation of flowering in legumes.

E1 and PHYA are newly identified key regulators in the photoperiodic control of flowering in legumes, diverging from traditional flowering pathways.

• Why it matters: Understanding flowering regulation in legumes is crucial for improving crop adaptation and productivity, especially as they are vital for soil health and food security.
• What they did: Researchers analyzed legume genetics and genomics, focusing on photoperiod-dependent flowering loci, revealing roles for photoreceptor PHYA and legume-specific E1-like transcription factors across diverse species.
• The result: Findings suggest that diversification of flowering strategies has enabled legumes to adapt to various environments, supporting their widespread distribution and agricultural success worldwide.
