According to pedigree and amplification results, PCR products of 8 WZSPs were selected to clone and sequence. Nine different nucleotide sequences were obtained. After comparing the DNA and protein sequences of the WZSPs SLA-3 alleles with the published GenBank SLA sequences, it was found that the SLA-3 alleles in WZSPs were all novel, but there were very few variations among them. Comparision of SLA-3 and HLA-A protein sequences indicated that there was more sequence homology. Meanwhile, the construction of a phylogenetic tree using the nucleotide sequences of 23 SLA-3 alleles and 1 HLA-A allele represented that the WZSP population owns its unique genetics resource. In this study, the alleles of SLA-3 on WZSP group were successfully detected and analyzed, which provided the firm basis on the genotype of SLA-3 for breeding specific haplotypes WZSPs.展开更多

We recorded internode length, internode diameter, number of internodes per culm, total culm height, total culm green weight and total culm volume of all five culm age classes. Data were gathered on 165 culms, each culm age class containing 33 culms with 3 culms per girth class. Culm height ranged from 3.2 to 15.3 m with highest mean of 9.15 m (in threeyear old culms) and maximum culm height was recorded in four-year old culms. Highest mean and maximum internode length (27.45 and 54.2 cm, respectively), internode diameter (3.12 and 4.75 cm, respectively) and total culm green weight (5.42 and 12.87 kg/culm, respectively) were recorded in three-year old culms and lowest in current-year culms. Best fitted regression models for all parameters were developed. Significant linear relationships between culm green weight and culm solid volume were documented for all five culm age classes. Their corresponding best-fit regression models were also developed.展开更多

Professor Changxiao Liu was a co-Chair of meeting organizing committee and Dr Duanyun Si was a member of meeting organizing committee. In the opening ceremony, Professor Liu representatives the host to welcome experts and scholars from around the world came to Tianjin to attend the meeting. The meeting provided the academic exchanges and learning opportunities for new and old friends, and wish the meeting more successful than the APISSX meeting in Shanghai six years ago, and wish the guests happy and impressed in Tianjin.展开更多
