Protein function

Encodes an enzyme involved in trehalose biosynthesis.

Phenotype

Single mutant:
tps1 single mutant is late flowering under both SD and LD conditions. [Wahl et al., 2013][van Dijken et al., 2004][Gü¾Œ¶˜¼mez et al., 2010]

Artificial microRNA:
Downregulation of TPS1 by an artificial microRNA leads to late flowering under both SD and LD conditions. [Wahl et al., 2013]

Overexpressor:
Overexpression of TPS1 in the stem cell niche leads to an early-flowering phenotype under both SD and LD conditions. [Wahl et al., 2013]

Function:
Required for normal embryo development, vegetative growth and transition to flowering. Regulates embryo growth, cell wall deposition, starch and sucrose degradation, but not cell differentiation. Involved in the regulation of glucose sensing and signaling genes during plant development. [Data from UniProt]
