Phenotypes of a mutant

• cells are bent and distended due to the lack of glucolipids [Pubmed|27684739]
• the inactivation of ''[gene|70412A747D1ED3E885126945DF02503667C13E5B|pgcA]'' suppresses the poor and filamentous growth of the ''[gene|1986DB3078FBA16D6ACCD70EEAC95C46564D0958|whiA] [gene|EAD44AA7D72510B70308FD0C9F159DBEDAEBBB74|zapA]'' double mutant [Pubmed|24097947]
• inactivation of ''[gene|70412A747D1ED3E885126945DF02503667C13E5B|pgcA]'' reduces sporulation efficiency to 0.1% that of wild type cells; smaller and wider mother cells with small forespores [Pubmed|26735940]
