The completed chloroplast genome of Ostrya trichocarpa

The whole chloroplast genome nucleotide sequence of Ostrya trichocarpa has been characterized from Illumina pair-end sequencing. The completed genome is 159,122 bp in length, with 121 genes annotated, including 86 protein-coding, 29 tRNA and 6 rRNA genes. The majority of gene occurred as a single copy, while 14 gene species occur in two copies. The circular genome exhibits a typical chloroplast genome structure comprising a large single copy region of 88,158 bp, a small single copy region of 18,758 bp and a pair of inverted repeats of 26,103 and 26,106 bp. The overall AT content of O. trichocarpa chloroplast genome is 63.54%, while the corresponding values of the LSC, SSC and IR regions are 65.73, 62.81 and 60.95%, respectively. Based on the SSR analysis, a total of 85 microsatellites with a length of at least 10 bp were detected in the O. trichocarpa genome. Further, phylogenetic analysis suggested that O. trichocarpa is closely related to Ostrya rehderiana .
