title: [Cloning and sequence analysis of mrjp1 cDNA from Apis cerana cerana].
abstract: A cDNA library was constructed from eight-day-old worker heads of Apis cerana cerana. A probe derived from part of Apis cerana genomic mrjp3 segment was used to screen this library. A total of 120 positive clones of mrjps were screened out from the cDNA library with DIG-probe. The positive clones were amplified and sequenced with T3/T7 primer. 12 sequences were similar to Apis cerana india and Apis mellifera mrjp1 gene by BLAST analysis. The cDNA sequence analysis indicated that the homology was 93.78% between Apis mellifera mrjp1 and Apis cerana mrjp1 while the homology was 99.36% between Apis cerana cerana and Apis cerana india. This result confirmed in molecular level that Apis cerana cerana and Apis cerana india had a common ancestor since the relationship between Apis cerana and Apis mellifera was more far.
