摘要：Aspergillus, as a genus of filamentous fungi, has members that display a variety of different behavioural strategies, which are affected by various environmental factors. The decoded genomic sequences of many species vary greatly in their evolutionary similarities, encouraging studies on the functions and evolution of the Aspergillus genome in complex natural environments. Here, we present the 26 Mb de novo assembled high-quality reference genome of Aspergillus glaucus 'China Changchun halophilic Aspergillus' (CCHA), which was isolated from the surface of plants growing near a salt mine in Jilin, China, based on data from whole-genome shotgun sequencing using Illumina Solexa technology. The sequence, coupled with data from comprehensive transcriptomic survey analyses, indicated that the redox state and transmembrane transport might be critical molecular mechanisms for the adaptation of A. glaucus 'CCHA' to the high-salt environment of the saltern. The isolation of salt tolerance-related genes, such as CCHA-2114, and their overexpression in Escherichia coli demonstrated that A. glucus 'CCHA' is an excellent organism for the isolation and identification of salt tolerant-related genes. These data expand our understanding of the evolution and functions of fungal and microbial genomes, and offer multiple target genes for crop salt-tolerance improvement through genetic engineering.
