Abstract:
The quantitative PCR (qPCR) method was firstly used to measure moss abundance with moss chloroplast gene rps4 as compared to that with cyanobacterial 16S rRNA gene and fungal 25-28S rRNA gene in the early succession stage of biological soil crusts (BSCs). Four sites with three BSC types collected from Hobq Desert of China, representing cyanobacterial-, lichen-, and moss-dominated BSCs were investigated. The copies of the moss rps4 gene, cyanobacterial 16S rRNA gene, and fungal 25-28S rRNA gene, chlorophyll a content, and the community composition variated significantly. The moss rps4 gene copies attained a significant positive correlation with chlorophyll a content and showed a cross-validation with relative moss biomass.
