Abstract:

The whole chloroplast genome resequencing of Carya illinoinensis cultivars‘Jinhua’‘Pawnee’and an old seedling individual were sequenced using Illumina sequencing platform,and their chloroplast genome characteristics were analyzed. The results showed that the three pecan chloroplast genomes were a typical tetrad structures with 160 819,162 611 and 160 762 bp in size,respectively. The gene sequences were highly conserved. A total of 124 genes,including 79 protein-coding genes,38 tRNA genes,and seven rRNA genes were identified from each of three pecan chloroplast genomes;repeat sequences detected were similar in categories,and 74,74 and 73 SSR loci were identified in their chloroplast genome sequence,respectively;phylogenetic analysis showed that they were most closely related to Annamocarya sinensis.

Key words: Carya cathayensis, chloroplast genome, simple sequence repeat, phylogeny relationship
