General Information

General Information	Comment	Organism
malfunction	disruption of PSS1 causes severe dwarfism, smaller lateral organs and reduced size of inflorescence meristem. Both cell division and cell elongation are affected in the pss1-1 mutant. The defect in meristem maintenance is recovered and the expression of WUS and CLV3 are restored in the pss1-1 clv1-1 double mutant. Both shootstemless (STM) and brevipedicellus (BP) are upregulated, and auxin distribution is disrupted in rosette leaves of pss1-1 mutant, expression of BP, which is also a regulator of internode development, is lost in the pss1-1 inflorescence stem. Phenotypes, detailed overview	Arabidopsis thaliana
physiological function	phosphatidylserine synthase 1 is required for inflorescence meristem and organ development in Arabidopsis thaliana. Phosphatidylserine, a quantitatively minor membrane phospholipid, is involved in many biological processes besides its role in membrane structure, e.g. it is required for microspore development. Expression of both genes WUSCHEL (WUS) and CLAVATA3 (CLV3) depend on PSS1. PSS1 plays essential roles in inflorescence meristem maintenance through the WUS-CLV pathway, and in leaf and internode development by differentially regulating the class I KNOX genes. PSS1 is involved in a lot of developmental processes and is vital for postembryonic development of Arabidopsis thaliana.
