The complete chloroplast genome of Ananas comosus var. erectifolius (L.B. Smith) Coppens & Leal

Abstract

Ananas comosus var. erectifolius (L.B. Smith) Coppens & Leal, a tropical plant from Bromeliaceae family, has immense applications, especially for fiber production of excellent quality. The lack of available chloroplast (cp) genome information limits its breeding and application. Here, we assembled its complete cp genome using Illumina high-throughput sequencing technology. The cp genome size is 159,983 bp, with 37.4% GC content, including a large single copy region (LSC) of 87,787 bp, a small single copy region (SSC) of 18,606 bp, and a pair of inverted repeat regions (IRs) of 26,795 bp. It encodes 89 protein-coding, 38 tRNA and 8 rRNA genes. Phylogenetic analysis showed that A. comosus var. erectifolius was close to Ananas comosus. The complete cp genome sequences could provide valuable information for variety breeding and genetic analysis of agronomic and economic traits in A. comosus var. erectifolius.
