We previously identified two genes, mfm1 and mfm2, with the potential to encode the M-factor mating pheromone of the fission yeast Schizosaccharomyces pombe (J. Davey, EMBO J. 11:951-960, 1992), but further analysis revealed that a mutant strain lacking both genes still produced active M-factor. Here we describe the isolation and characterization of a third M-factor gene, mfm3. A mutant lacking all three genes fails to produce M-factor, indicating that all functional M-factor genes now have been identified. The triple mutant exhibits an absolute mating defect in M cells, a defect that is not rescued by addition of exogenous M-factor. A mutational analysis reveals that all three mfm genes contribute to the production of M-factor. Their transcription is limited to M cells and requires the mat1-Mc and ste11 gene products. Each gene is induced when the cells are starved of nitrogen and further induced by a pheromone signal. Additionally, the signal transduction machinery associated with the pheromone response is required for transcription of the mfm genes in both stimulated and unstimulated cells.

Plant Defence Mechanisms

Tomato (Solanum lycopersicum) are consid­ered one of the most important vegetable crops and infected by numbers of different diseases. Studying the use of biological alternatives, instead of chemical substances against plant diseases became necessary for the treatment by beneficial microorganisms endophytes, which can excrete natural products benefits to plant in reducing disease severity, promoting growth and inducing plant defence mechanisms. In this work, three endophytes strains were isolated from tomato stems and their 16srDNA have been found to belong to Bacillus species. The first strain was named BMG100, the second BMG101 and the third BMG102. Two Bacillus strains BMG100 and BMG101 have been found to harbour synthetases genes from three lipopeptides families; surfactin, plipastatin, and iturin (mycosubtilin) which can be detected by degenerated primers designed to detect the presence of synthetases genes encoding lipopeptides. The lipopeptides production was proved by their quantification using High Performance Liquid Chromatography (HPLC), whereas BMG100 produced 105, 178 and 293 mg/L of plipastatin, mycosubtilin and surfactin, respectively, BMG101 produced 385 mg/L of surfactin and 236 mg/L of mycosubtilin, while BMG102 showed no lipopeptides production.
