LRG1, previously characterized as a Rho-GAP that regulates beta-1,3-glucan synthesis, was identified using a filtration screen designed to isolate genes that promote cell aggregation in Sigma1278b Saccharomyces cerevisiae. Disruption of LRG1 in haploid cells resulted in enhanced invasive growth and a strain-specific 'clustered' phenotype that is a consequence of failed separation of mother and daughter cells. Genetic analysis revealed that clustering required functional ROM2, FKS1 and STE12 but not FLO8 or FLO11. Additionally, this phenotype required sufficient nitrogen. beta-1,3-Glucan content was elevated in lrg1 haploids and these cells possessed a thicker cell wall and septum than wild-type strains. Additional glucan at the bud site inhibited separation of lrg1 mutants as the clustered phenotype was repressed by expression of the glucanases ENG1 or EGT2.
