英文摘要	The elevational and latitudinal diversity patterns of microbial taxa have attracted great attention in the past decade. recently, the distribution of functional attributes has been in the spotlight. here, we report a study profiling soil microbial communities along an elevation gradient (500-2200 m) on changbai mountain. using a comprehensive functional gene microarray (geochip 5.0), we found that microbial functional gene richness exhibited a dramatic increase at the treeline ecotone, but the bacterial taxonomic and phylogenetic diversity based on 16s rrna gene sequencing did not exhibit such a similar trend. however, the beta-diversity (compositional dissimilarity among sites) pattern for both bacterial taxa and functional genes was similar, showing significant elevational distance-decay patterns which presented increased dissimilarity with elevation. the bacterial taxonomic diversity/structure was strongly influenced by soil ph, while the functional gene diversity/structure was significantly correlated with soil dissolved organic carbon (doc). this finding highlights that soil doc may be a good predictor in determining the elevational distribution of microbial functional genes. the finding of significant shifts in functional gene diversity at the treeline ecotone could also provide valuable information for predicting the responses of microbial functions to climate change.
