Project description:Global warming has shifted climate zones poleward or upward. However, understanding the responses and mechanism of microbial community structure and functions relevant to natural climate zone succession is challenged by the high complexity of microbial communities. Here, we examined soil microbial community in three broadleaved forests located in the Wulu Mountain (WLM, temperate climate), Funiu Mountain (FNM, at the border of temperate and subtropical climate zones), or Shennongjia Mountain (SNJ, subtropical climate).Soils were characterized for geochemistry, Illumina sequencing was used to determine microbial taxonomic communities and GeoChips 5.0 were used to determine microbial functional genes.
Project description:A comparision of soil microbial functional genes of three types of subtropical broad-leaved forests Microbial functional structure was significantly different among SBFs (P < 0.05). Compared to the DBF and the EBF, the MBF had higher alpha-diversity of functional genes but lower beta-diversity, and showed more complex functional gene networks.
Project description:Here, we applied a microarray-based metagenomics technology termed GeoChip 5.0 to examined functional gene structure of microbes in three biomes, including boreal, temperate and tropical area.

Project description:Ganoderma colossum (Fr.) Baker, a white rot fungus distributed in tropical and subtropical forests, is a rare Ganoderma mushroom belonging to the family Ganodermataceae. In Asia, the fruiting body of G. colossum has been used as tonics or as folk medicine for a variety of illnesses, including malignant diseases. Colossolactone H (colo H) as a new compound was isolated and studied for its anticancer mechanism in human lung cancer H1650 cells. We used microarrays to analyze the gene expression changes upon colo H treatment that helped underlying the molecular mechanism of colo H in H1650 lung cancer cells. The H1650 cells treated with colo H for 12 and 24 h for RNA extraction and hybridization on Affymetrix microarrays.
