General Information

General Information	Comment	Organism
physiological function	PSS1 regulates post-Golgi vesicle secretion to intercellular spaces. Mutation of PSS1 leads to compromised delivery of CESA4 and sec-GFP towards the cell surface, resulting in weakened intercellular adhesion and disorganized cell arrangement in parenchyma. The phenotype sui1-4 of PSS1 mutants is caused largely by the reduction in cellulose contents in the whole plant and detrimental delivery of pectins in the uppermost internode. PSS1 and product phosphatidylserine localize to organelles associated with exocytosis	Oryza sativa Japonica Group
