They all contain 13 protein coding gene,2 rRNA gene,22 tRNA gene and 1 D-Loop.The base composition for the four nucleotides is A-32.0%,C-27.6%,G-14.7%,T-25.8%,And it is A-32.5%,C-26.9%,G-14.1%,T-26.5%for Yellow-throated Marten.But there are some definite differences in base composition,the using of Initiation codon and Stop codon,and the mode of repeat sequences in control region.The codon usages of Manes have bias,and the ttiird locations of codon of protein-coding genes have the higher frequency in using A and C.There may be some relativity with the content of A and C in D-loop,namely,it has relation with the mode of repeat sequences.The complete mitochondrial genome of the Sable and Yellow-throated Marten were submitted to GenBank,and the accession number are FJ429093 and FJ719367 respectively.3、The complete mitochondrial genome of 6 other species of Mustelidae from GenBank and some sequences of D-loop from the 6 species were aligned.

In order to determine the genetic differences between high molecular weigh glutenin subunits 17+18 and 7+8, HMW-GS 17+18 was introduced into Longmai 20 by 6 consecutive backcrosses with biochemical marker assisted selection. The near isogenic lines of HMW-GS 17+18 and 7+8 were obtained and grown in the experimental field of Crop Breeding Institute of Heilongjiang Academy of Agricultural Sciences in 2006. The field experiments were designed using the method of two line-contrast arrangement with four replicates.
