Q8GWT1 · GAUTE_ARATH

Function

function

May be involved in pectin and/or xylans biosynthesis in cell walls (By similarity).
Together with GAUT13, required for pollen tube growth, possibly through the regulation of pectin biosynthesis and repartition in the pollen tube wall (PubMed:23709340).

Pathway

Glycan metabolism; pectin biosynthesis.

Phenotypes & Variants

Disruption phenotype

No obvious phenotype (PubMed:19825675).
Increased galacturonic acid and Gal content in cell wall, but reduced xylose and rhamnose content (PubMed:19825675).
The gaut13 gaut14 double mutant is defective in male gametophyte function; swollen pollen tubes disturbed in elongation, and characterized by a disorganized outer layer cell wall with an altered repartition of pectin (e.g. homogalacturonan) (PubMed:23709340).

Variants
