Gene Ontology:

• GO:0009860  — acts upstream of or within — pollen tube growth
• GO:0010584  — acts upstream of or within — pollen exine formation
• GO:0055085  — involved in — transmembrane transport
• GO:0022857  — enables — transmembrane transporter activity
• GO:0005886  — is active in — plasma membrane
• GO:0005886  — located in — plasma membrane

Germplasm Phenotype:

• fst1  — The fst1 mutant results in strong reduction of beta-1,2-linked flavonol glycosides (sophorosides) on the pollen of Arabidopsis. Vitality and fertility appear identical to the wild type under standard greenhouse conditions.
