Diversity and community structure of basidiomycete laccase gene from subtropical broad-leaved and coniferous forest ecosystems based on cDNA cloning

Abstract

Decomposition of forest litter regulates the cycling of nutrients in forest ecosystems and influences the net carbon storage for terrestrial ecosystems. Laccase enzyme mainly produced by basidiomycetes plays a central role in lignin degradation and thus contributes to the cycling of soil organic matter. Compared to many studies of basidiomycetous laccase gene diversity in pure broad-leaved or coniferous forests, comparative data on diversity of this gene from different forest
