RESEARCH INTEREST


I am mainly working on the direction of fungal ecological genomics using Trichoderma spp. as the model for fitness, speciation, diversity and evolution as well as their potential application in industry. Ubiquitously spread on land and ocean, fungi form one of the most diverse eukaryotic phyla with millions of species. However, the peculiarities of their biology such as their pleomorphic life cycles with frequent prevalence of asexual reproduction, prolonged stages of dormancy and superior metabolic plasticity impede studies on fungal evolution and ecology, leaving this group largely unexplored. On the other hand, the unique fungal traits can shed light on the evolutionary forces that shape their environmental adaptions. Filamentous fungi that disperse through aerial spores produce unique amphiphilic and highly surface-active proteins, hydrophobins (HFBs), which coat spores and mediate a multitude of environmental interactions. We recently exploited a library of hfb-edited mutants for closely-related Trichoderma species and the HFBome in this fungus at a genus-wide level. The results pointed fungal HFBs are linked with their fitness that address fungal development, reproductive potential and stress resistance. And the net contribution of such genes to fitness was found to result from the evolutionary tradeoff between individual effects. In parallel, the question how spores get coated by such a huge HFB matrix on their surface also raised the interest of our research. Using the HFB-enriched mold Trichoderma and the HFB‐free yeast Pichia pastoris, we found that HFBs tended to accumulate in lipid bodies (LBs). Subsequent internalization of such LBs in vacuoles resulted in the maintenance of turgor pressure in aerial hyphae which are seen as “conidia rings” on colony. Besides, I am also interested into exploring the functional roles of other small secreted cysteine-rich proteins (SSCPs) playing in the complex environment called “hyphasphere” that created by the fungus itself.
