additional information Colletotrichum gloeosporioides when the fungus is grown at pH 4.0 or 6.0 in the absence of a nitrogen source, neither pelB (encoding pectate lyase) transcription nor pectate lyase secretion is detected. pelB transcription and pectate lyase secretion are both detected when Colletotrichum gloeosporioides is grown at pH 6.0 in the presence of ammonia accumulated from different nitrogen sources. The early accumulation of ammonia induces early pelB expression and pectate lyase secretion. Nit mutants of Colletotrichum gloeosporioides, which cannot utilize KNO3 as a nitrogen source, do not secrete ammonia, alkalinize the medium, or secrete pectate lyase. If Nit mutants are grown at pH 6.0 in the presence of glutamate, then pectate lyase secretion is induced ?
