  • a Values are the percentages of each base among 76 MSEs from middle sporulation genes that are not derepressed in a sum1 mutant (see Materials and Methods for details).

  • b This more narrow consensus was chosen using the preferences noted in this table (see Materials and Methods for details). Bases that exhibit statistically significant differences from the control set of sequences are shown in bold and underlined. Y: C or T; N: A, G, C, or T. Statistical comparison of these base preferences to those in the control set (Table 6) yielded the following chi square test P values: Position 5, 0.0011; 6, 0.0058; 9, 2.5 × 10−4; and 14, 0.0013.
