  1. Glycerol-induced sporulation markers displaying a mutant sporulation phenotype (Phenotype), encoding proteins identified in glycerol induced spores (Protein), or associated with upregulated activities (Activity). Mxan; gene id; S: starvation induced spores; G: glycerol induced spores; Max. reg.: maximum regulation in microarray analysis; NT: not tested; Y: yes; N: no; Class: I (peak upregulation 0.5-1 hours) or II (peak upregulation was 2-4 hours); ?: gene unknown. * gene not analyzable on chip but subsequent RT-PCR analysis indicated peak 724-fold regulation at 0.5 hours after induction (map I criteria). Underlined markers displayed a transcriptional regulation pattern consistent with the prediction from the literature.
