The complete chloroplast genome sequence of Ulmus glabra ‘Pendula’ (Ulmaceae)

摘要

In this study, the whole chloroplast genome of Ulmus glabra ‘Pendula’ was sequenced, assembled, annotated and characterized for the first time. The results showed that the total length of the chloroplast genome of U. glabra ‘Pendula’ was 159,305?bp and the GC content was 35.58%. It had a circular tetrad structure of the chloroplast genome of typical angiosperms, including a large single-copy (LSC) with length of 87,916?bp, a small single-copy (SSC) with length of 18,693?bp, and a pair of inverted repeat sequence (IRs) of 26,348?bp. A total of 131 genes were identified, including 86 protein coding genes, 37 tRNA genes, and 8 rRNA genes. Based on the whole chloroplast genome sequence, the phylogenetic trees of 14 plants in U. glabra ‘Pendula’ and NCBI database were constructed, and the phylogenetic position of U. glabra ‘Pendula’ in Ulmaceae was identified. The results provided important information for the identification of genetic relationship of U. glabra ‘Pendula’, and will also promote the functional analysis of genes related to agronomic traits controlled by the chloroplast genome of U. glabra ‘Pendula’.
