Pmr1 is the Golgi/ER calcium pump, while Rch1 is a newly identified negative regulator of calcium influx in the plasma membrane of yeast cells. We show here that CaRch1 plays a dominant role over CaPmr1 in response of Candida albicans to SDS and tunicamycin stresses, while CaPmr1 has a major role in cell wall stress. Deletion of CaRCH1 increases the calcium/calcineurin signaling level in cells lacking CaPMR1. Calcineurin function is required for the role of CaRch1 in SDS stresses, while it is required for the function of CaPmr1 under all conditions examined. Disruption of CaRCH1 alone does not reduce the cell wall chitin, mannan or β-glucan content, but lack of CaRCH1 slightly decreases the chitin content of cells lacking CaPMR1. Furthermore, CaRch1 and CaPmr1 have an additive effect on filamentation of C. albicans cells in vitro. Cells lacking both CaRCH1 and CaPMR1 and cells lacking CaPMR1 alone show a similar degree of virulence attenuation, being much more attenuated than cells lacking CaRCH1 alone. Therefore, CaRch1 genetically interacts with CaPmr1 in the regulation of in vitro filamentation in C. albicans.
