  60. 60.  Use high-throughput sequencing and bioinformatics to analyze the diversity of the functional diazotrophs and to determine the major functional diazotrophs in sugarcane;  Isolate the major functional diazotrophs from sugarcane plants or select ones from the available culture collection for diazotrophs in China;  Use the major functional diazotrophs to inoculate the sugarcane cultivars shown high nifH expression activity;
  61. 61. Use qRT-PCR and 15N isotope dilution methods to determine the efficient sugarcane N2-fixing systems; Use in situ hybridization assay to find the N2- fixing location in sugarcane plants. Detect the effects of soil pH, nitrogen and phosphorous levels, and microbes on nitrogen fixation efficiency in sugarcane.

  72. 72. Genome research  Although sugarcane genomes are very complex and the genome research progresses very slowly, it is important to sequence the whole genome.  After years of preparation, Sugarcane Research Center, CAAS/ GXAAS decided to begin the whole sugarcane genome sequencing program in China: F13TSFSCKF1043.  This is being conducted with a local collection of Saccharum spontaneum, GXS87-16 (2n=64) with the cooperation of Beijing Genome Institute (BGI) –Shenzhen.
  73. 73. • The first term is planning to be completed in 3 years since July 2013. In the first term of the project, 100 X (100 Gb) of WGS sequencing will be done, 10 X BAC clones will be constructed and 1 X (about 10,000 clones) will be selected for BAC library construction and sequencing. These data will be used to estimate complexity of sugarcane genome, and the primary sequence map will be obtained.
  74. 74.  The program has completed small fragments sequencing, and the data are under analyses.  BAC library has been completed, and will be used for sequencing.
