| analysis of nifh gene diversity in red soil amended with manure in jiangxi, south china. | in order to understand the community structure of diazotrophs in red soil and effects of organic manure application on the structure, four nifh gene libraries were constructed: the control (ck), low manure (lm), high manure (hm), and high manure adding lime (ml). totally 150 nifh gene clones were screened and grouped into 21 clusters by rflp analysis. existence of dominant patterns was observed in all libraries, which counted for over 96% of clones in library hm and about 56 approximately 72% in ... | 2009 | 19412595 |
