Gene Details:

Functional Descriptions:

  • SlFHY3 physically interacts with ELONGATED HYPOCOTYL5 (SlHY5) to promote the transcriptional activity of SlHY5 on MYO-INOSITOL-1-PHOSPHATE SYNTHASE 3 (SlMIPS3) and induce myo-inositol accumulation in tomato plants under cold stress.
  • Our study reveals a key molecular regulatory mechanism by which plants integrate internal cues (inositol metabolism) and environmental light signaling to initiate and control cold tolerance through transcriptional activation of SlMIPS3 by the SlFHY3–SlHY5 regulatory module.
  • These results indicate that LR : FR-induced SlHY5 transcription is dependent on SlFHY3 in tomato plants during cold stress.
  • Activation and negative feedback regulation of SlHY5 transcription by the SlBBX20/21-SlHY5 transcription factor module in UV-B signaling.
  • SlFHY3 and SlHY5 act compliantly to enhance cold tolerance through the integration of myo-inositol and light signaling in tomato.
  • SlHY5 Integrates Temperature, Light, and Hormone Signaling to Balance Plant Growth and Cold Tolerance.
  • Phytochrome A-dependent SlHY5 accumulation resulted in an increased abscisic acid/gibberellin ratio, which was accompanied by growth cessation and induction of cold response.
  • The transcription factor SlHY5 regulates the ripening of tomato fruit at both the transcriptional and translational levels.
  • Our findings unravel the regulatory mechanisms of SlHY5 in controlling fruit ripening and nutritional quality and uncover the multifaceted regulation of gene expression by transcription factors.
  • A mutation to ELONGATED HYPOCOTYL5 (HY5) increased tomato fruit fructose and glucose contents by approximately 20% (relative to the wild-type levels).
