| 1 | In vivo gene expression profiling of the entomopathogenic fungus Beauveria bassiana elucidates its infection stratagems in Anopheles mosquito显示文摘The use of entomopathogenic fungi to control mosquitoes is a promising tool for reducing vector-borne disease transmission.To better understand infection stratagems of insect pathogenic fungi,we analyzed the global gene expression profiling of Beauveria bassiana at 36,60,84 and 108 h after topical infection of Anopheles stephensi adult mosquitoes using RNA sequencing(RNA-Seq).A total of 5,354 differentially expressed genes(DEGs) are identified over the course of fungal infection.When the fungus grows on the mosquito cuticle,up-regulated DEGs include adhesion-related genes involved in cuticle attachment,Pthll-like GPCRs hypothesized to be involved in host recognition,and extracellular enzymes involved in the degradation and penetration of the mosquito cuticle.Once in the mosquito hemocoel,the fungus evades mosquito immune system probably through up-regulating expression of |3-l,3-glucan degrading enzymes and chitin synthesis enzymes for remodeling of cell walls.Moreover,six previous unknown SSCP(small secreted cysteine-rich proteins) are significantly up-regulated,which may serve as 'effectors' to suppress host defense responses.B.bassiana also induces large amounts of antioxidant genes to mitigate host-generated exogenous oxidative stress.At late stage of infection,B.bassiana activates a broad spectrum of genes including nutrient degrading enzymes,some transporters and metabolism pathway components,to exploit mosquito tissues and hemolymph as a nutrient source for hyphal growth.These findings establish an important framework of knowledge for further comprehensive elucidation of fungal pathogenesis and molecular mechanism of Beauveria-mosqaito interactions. | Yiling Lai Huan Chen Ge Wei Guandong Wang Fang Li Sibao Wang | 2017 | Science China(Life Sciences)2017，60，8： | 5 |

| 3 | Functional response of the fungus Hirsutella rhossiliensis to the nematode, Heterodera glycines显示文摘Functional response is a key index in determining the population fluctuation in predation. However, the lack of operable research system limits the studies on functional response of fungal predators. Hirsutella rhossiliensis is a dominant parasite of the soybean cyst nematode, Heterodera glycines. In a soil microcosm bioassay, we determined fungal biomass at different days within 21 days after inoculation, and parasitism rate of H. glycines by the fungus was determined. The functional response of H. rhossiliensis to H. glycines was established and found to be Holling's type III, which was influenced by mycelial densities. Meanwhile, we conducted anti-fungal analysis of metabolic fractions extracted from H. rhossiliensis to explain the potential mechanism of the intraspecific competition illustrated by functional response. The result of anti-fungal experiments indicated that the fungal predators had more complicated interaction at population level than expected, which might be regulated by self-inhibition metabolite(s). This study was the first functional response study of fungal predators in microcosm. With the increasing recognition of emerging fungal threats to animal, plant, and ecosystem health, the methodologies and hypotheses proposed in this study might inspire further research in fungal ecology. | SHU Chi LAI YiLing YANG EnCe CHEN SenYu XIANG MeiChun LIU XingZhong | 2015 | Science China(Life Sciences)2015，58，7： | 1 |
