Abstract

The genus Cardiocrinum (Endlicher) Lindley (Liliaceae) comprises three herbaceous perennial species that are distributed in East Asian temperate-deciduous forests. Although all three Cardiocrinum species have horticultural and medical uses, studies related to species identification and molecular phylogenetic analysis of this genus have not been reported. Here, we report the complete chloroplast (cp) sequences of each Cardiocrinum species using Illumina paired-end sequencing technology. The cp genomes of C. giganteum, C. cathayanum, and C. cordatum were found to be 152,653, 152,415, and 152,410 bp in length, respectively, including a pair of inverted repeat (IR) regions (26,364-26,500 bp) separated by a large single-copy (LSC) region (82,186-82,368 bp) and a small single-copy (SSC) region (17,309-17,344 bp). Each cp genome contained the same 112 unique genes consisting of 30 transfer RNA genes, 4 ribosomal RNA genes, and 78 protein-coding genes. Gene content, gene order, AT content, and IR/SC boundary structures were almost the same among the three Cardiocrinum cp genomes, yet their lengths varied due to contraction/expansion of the IR/SC borders. Simple sequence repeat (SSR) analysis further indicated the richest SSRs in these cp genomes to be A/T mononucleotides. A total of 45, 57, and 45 repeats were identified in C. giganteum, C. cathayanum, and C. cordatum, respectively. Six cpDNA markers (rps19, rpoC2-rpoC1, trnS-psbZ, trnM-atpE, psaC-ndhE, ycf15-ycf1) with the percentage of variable sites higher than 0.95% were identified. Phylogenomic analyses of the complete cp genomes and 74 protein-coding genes strongly supported the monophyly of Cardiocrinum and a sister relationship between C. cathayanum and C. cordatum. The availability of these cp genomes provides valuable genetic information for further population genetics and phylogeography studies on Cardiocrinum.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 September 2019.
All research outputs
#6,466,487
of 22,950,943 outputs
Outputs from Frontiers in Plant Science
#3,707
of 20,377 outputs
Outputs of similar age
#122,251
of 421,772 outputs
Outputs of similar age from Frontiers in Plant Science
#86
of 529 outputs
Altmetric has tracked 22,950,943 research outputs across all sources so far. This one has received more attention than most of these and is in the 70th percentile.
So far Altmetric has tracked 20,377 research outputs from this source. They receive a mean Attention Score of 4.0. This one has done well, scoring higher than 81% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 421,772 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 529 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 82% of its contemporaries.
