A recent study in mBio reports the construction and preliminary screening of a library containing mutants of 99 of the 119 predicted protein kinases in Candida albicans (the majority of the remaining 20 are probably essential) (J. Kramara, M.-J. Kim, T. L. Ollinger, L. C. Ristow, et al., mBio e01249-24, 2024, https://doi.org/10.1128/mbio.01249-24). Using a quantitative competition assay in 10 conditions that represent nutritional, osmotic, cell wall, and pH stresses that are considered to model various aspects of the host environment allowed them to phenotypically cluster kinases, which highlight both the integration and specialization of signaling pathways, suggesting novel functions for many kinases. In addition, they tackle two complex and partially overlapping differentiation events, hyphal morphogenesis and biofilm formation. They find that a remarkable 88% of the viable kinase mutants in C. albicans affect hyphal growth, illustrating how integrated morphogenesis is in the overall biology of this organism, and begin to dissect the regulatory relationships that control this key virulence trait.
