It is well understood that the yak originates from China, but facts regarding origin time and evolutionary relationship with other species of Bovini, are largely disputed. Here, we have analyzed the phylogenetic relationship of eight representative species of Bovini, based on the Cytochrome b gene of mitochondrial DNA and TSPY gene of chromosome Y. We also estimated the divergence times of these different...
The study on molecular structure of Fusarium proliferatum clinically isolated can provide the basis for accurate diagnosis and treatment of F. proliferatum infection. The rDNA ITS gene of 6 strains that had been identified as Fusarium proliferatum based on morphological were cloned and sequenced. The molecule phylogenetic tree was constructed based on rDNA ITS sequences, and the 6 genus were divided...
The specific segment in 3' terminal region of strawberry mild yellow edge virus (SMYEV) genome was amplified by 3' rapid amplification of cDNA ends (RACE). Ten Chinese isolates were sequenced. Sequence analysis of coat protein gene showed nucleotide and deduced amino acid identities ranged from 76.8 to 100% and 86.4 to 100%, respectively. Phylogenetic analysis showed that all isolates of SMYEV fell...
