编码

By employing two kinds of molecular marker of mitochondrial DNA, i. e. Cyt b and CoI gene, the sequences of 15 species representing 6 families from Passeriformes were compared. We analysed their sequences compose and characteristic with the sorft of MEG3.1, and built the phylogenetic trees in PAUP~*4.0. We deeply analysed the feasibility that CoI gene qua the marker to research the phylogenetic relationship of Passeriformes, and afford the academic proof for building the DNA barcoding of the birds.

The full-length cDNAs of rice and wheat S-adenosylmethionine decarboxylase gene were isolated and characterized. The rice SAMDC cDNA is 1560 bp in length, encoding a polypeptide of 398 amino acids, and the wheat SAMDC cDNA is 1351 bp in length, encoding a polypeptide of 392 amino acids. Both the rice and wheat SAMDC proteins contain the conserved proenzyme cleavage site and the PEST domains, which are commonly found in the SAMDC protein sequences of all eukaryotes.
