摘要：

Only eight genes are known to be involved in the phototropic response of Phycomyces (madA-H). Mutants affected in these genes have played a major role in the analysis of photosensory transduction processes in this system. A set of new mutants isolated by Alvarez et al. (1989) that are unable to bend towards dim unilateral blue light were studied by complementation and recombination. Two of these mutants have mutations in madE, one has a mutation in madF and one is a double madE madF mutant. The three remaining mutants tested did not complement each other and showed positive complementation with strains carrying mutations in the genes madA, madB, and madC, indicating that they carried mutations in a new gene designated madI. Recombination analysis showed that madI is unlinked to madA, madB and madC. © 1990 Springer-Verlag.
