Appears in the following schemes

Hormone pathway

Protein function

Encodes a Gibberellin-regulated protein involved in the promotion of GA responses.

Phenotype

Overexpressor:
GASA5 overexpressor is late flowering under both SD and LD conditions. [Zhang et al., 2009]

Single mutant:
gasa5 single mutant is early flowering under both SD and LD conditions. [Zhang et al., 2009]

Remarks:
GASA5 single mutant shows reduced FLC expression levels while GASA5 overexpressor displays increased FLC expression levels. [Zhang et al., 2009]

Function:
Gibberellin-regulated protein that acts as a negative regulator of gibberellin-induced flowering and stem growth. May inhibit flowering and inflorescence growth via a pathway involving GAI and by enhancing FLC expression and repressing FT and LFY. Acts as a negative regulator in thermotolerance by resogulating both salicylic acid (SA) signaling and heat shock-protein accumulation. [Data from UniProt]
