Previous work has indicated that Whi3 might govern these processes by additional, yet unknown mechanisms. In this study, we have identified additional effectors of Whi3 that include the G1 cyclins Cln1/Cln2 and two known regulators of biofilm formation, the catalytic PKA subunit Tpk1 and the transcriptional activator Tec1. We also provide evidence that Whi3 regulates production of these factors by post-transcriptional control and might exert this function by affecting translational elongation. Unexpectedly, we also discovered that Whi3 is a key regulator of cellular ploidy, because haploid whi3Δ mutant strains exhibit a significant increase-in-ploidy phenotype that depends on environmental conditions. Our data further suggest that Whi3 might control stability of ploidy by affecting the expression of many key genes involved in sister chromatid cohesion and of NIP100 that encodes a component of the yeast dynactin complex for chromosome distribution. Finally, we show that absence of Whi3 induces a transcriptional stress response in haploid cells that is relieved by whole-genome duplication. In summary, our study suggests that the RNA-binding protein Whi3 acts as a central regulator of cell division and development by post-transcriptional control of key genes involved in chromosome distribution and cell signaling."xsd:string |
