Gene Details:

• Gene ID: Glyma.16G017400
• Gene Symbol: GmLHY1a
• Gene Name: LATE ELONGATED HYPOCOTYL 1
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• Two homologous LHY pairs negatively control soybean drought tolerance by repressing the abscisic acid responses.
• Genetic dissections showed that two homologous pairs of LHY1a and LHY1b redundantly control the drought response.
• Functional characterization of LHY1a and LHY1b in Arabidopsis and soybean further supported the notion that GmLHYs can maintain cellular homeostasis through the ABA signaling pathway under drought stress.
• The expressions of four GmLHYs were all induced by drought, and the quadruple mutants of GmLHYs demonstrated significantly improved drought tolerance. Transcriptome profiling suggested that the abscisic acid (ABA) signaling pathway is regulated by GmLHYs to respond to drought tolerance.
• LHY2a positively regulates photoperiodic flowering time.
• These findings indicated that the Gmlhy1a1b2a2b mutant has a low active gibberellin level and that it is a GA biosynthesis-deficient mutant.
