ABSTRACT
Aspergillus fumigatus is an opportunistic human pathogen that causes various complications in patients with a weakened immune system functions. Asexual spores of A. fumigatus are responsible for initiation of aspergillosis. Long-term viability and proper germination of dormant conidia depend on trehalose accumulation, which protect the spores against thermal and oxidative stress. A putative Myb transcription factor, MybA has been recently found to be responsible for a variety of physiological and molecular roles ranging from conidiation, spore viability, trehalose accumulation, cell wall integrity and protection against reactive oxygen species. In this perspective review, we discuss the recent findings of MybA and its overlapping functions with the other regulators of conidia viability and trehalose accumulation. Therefore, the aim of this perspective is to raise interesting and stimulating questions on the molecular functions of MybA in conidiation and trehalose biogenesis and to question its genetic and physical interactions with the other regulators of conidial viability.
