Characterization of the Plastid Genome of the Vulnerable Endemic Indosasa lipoensis and Phylogenetic Analysis

Indosasa lipoensis, an ornamental garden plant, belongs to the genus of subfamily Bambooaceae within Poaceae. lipoensis is endangered and requires protection owing its relatively narrow distribution area. Chloroplast (cp) genome offers a novel awareness evolutionary genetic variation higher plants. Herein, we assembled elucidated complete cp I. compared it with four previously published genomes from this genus. The was 139,655 bp in size, typical quadripartite structure, encompassing large single-copy region (LSC, 83,256 bp), small (SSC, 12,809 pair inverted repeat regions (IR, 21,795 bp). consisted 130 genes 84 protein-coding (CDS), 38 tRNA genes, 8 rRNA genes. plastomes were highly conservative, other bamboo species, exhibited similar patterns codon usage, number sequences, expansion contraction IR boundary. Five hypervariable hotspots identified as potential DNA barcodes, namely rbcL, petA, petB, trnL-UAG, ndhE-ndhI, respectively. Phylogenetic analysis based on revealed, high resolution, that gigantea most closely related. Overall, these results provided valuable characterization for future conservation, evaluation, breeding lipoensis.
