Complete chloroplast genome of Isoetes orientalis (Isoetaceae), an endangered quillwort from China.

ABSTRACT: Isoetes orientalis is an endangered hexaploidy species of Isoetaceae in China and the complete chloroplast genome of this species has not been reported. In the present study, a complete chloroplast genome of Isoetes orientalis (Isoetaceae) was assembled and annotated. This chloroplast genome has a circular structure of 145,504 bp in length, comprising a pair of inverted repeat (IR) regions of 13,207 bp each, a large single-copy (LSC) region of 91,864 bp, and a small single-copy (SSC) region of 27,226 bp. The chloroplast genome contains 136 genes, including 84 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis showed that I. orientalis was closely related to I. sinensis. These results provide additional resources for future studies on Isoetes from China and across the globe.

Complete chloroplast genome of Isoetes hypsophila (Isoetaceae), the Endangered quillwort in China.

Project description:Isoetes hypsophila Hand.-Mazz. is an Endangered quillwort living in plateau wetlands in China. In the present study, the complete chloroplast genome of I. hypsophila was assembled. It is a circular form of 146,362 bp in length, comprising a pair of inverted repeat (IR) regions of 13,691 bp, a large single copy (LSC) of 91,741 bp, and a small single copy (SSC) of 27,239 bp. After annotation, a total of 135 genes were predicted, which are 84 encode proteins 37 tRNA and 8 rRNA. The phylogenetic analysis indicated that I. hypsophila clustered with a clade of I. sinensis, I. taiwanensis and I. yunguiensis with strong support value. The chloroplast genome will contribute to further research and conservation of I. hypsophila.

Complete chloroplast genome of Isoetes sinensis, an endemic fern in China.

Project description:Isoetes sinensis is the only aquatic pteridophyte in China with high research value of phylogeny. It is in endangered status. A conservation strategy is therefore imperative for this endangered pteridophyte. In the study, the complete chloroplast (cp) genome of Isoetes sinensis (Isoetaceae) was assembled and annotated. It is the full length of 145,492 bp, include large single-copy (LSC) region of 91,865 bp, small single-copy (SSC) region of 13,207 bp, and a pair of invert repeats (IR) regions of 27,213 bp. Plastid genome contains 135 genes, 71 protein-coding genes, 36 tRNA genes, and eight rRNA genes. Phylogenetic analysis suggested I. sinensis was most closely related to the clade of I. melanospora, I. mattaponica, I. graniticola, I. engelmannii, I. flaccida, I. valida, and I. butleri, with strong support (bootstrap = 100%). The cp genome will contribute to further research and conservation of I. sinensis.

Isoetes mississippiensis: A new quillwort from Mississippi, USA.

Project description:Isoetes mississippiensis S.W. Leonard, W.C. Taylor, L.J. Musselman and R.D. Bray (Isoetaceae, Lycopodiophyta) is a new species known from two sites along tributaries of the Pearl River in southern Mississippi. This species is distinguished from other species in the southeastern United States by a combination of character states including a basic diploid (2n=22) chromosome count, laevigate megaspores, and a narrow velum covering less than one-third of the adaxial sporangium wall.
