FIG.2.

Physical map of nla loci implicated in development. Gene designations were taken from the work of R. D. Welch, J. S. Jakobsen, and D. Kaiser (personal communication). The potential functions of some of the gene products are indicated in parentheses below the gene designations. “Unknown” indicates that in BLAST searches, no potential function for a gene product was obtained. Black inverted triangles represent insertions within nla genes, and gray inverted triangles represent insertions downstream of nla genes. The motility (Mot), aggregation (Agg), and sporulation (Spo) phenotypes produced by each insertion are indicated above the insertions. The data were taken from the results shown in Table 1, Table 2, and Table 4. Double bars (||) at the end of a line indicate that the upstream or downstream sequence was not available.
