Abstract:
Isoetes japonica A. Braun is a heterosporous quillwort living in low-altitude areas in Japan. In the present study, the complete chloroplast genome of I. japonica was assembled and annotated. This chloroplast genome is a circular structure of 145,517 bp in length, comprising a pair of inverted repeat (IR) regions of 13,204 bp each, a large single copy (LSC) region of 91,868 bp, and a small single copy (SSC) region of 27,241 bp. The chloroplast genome contains 135 genes, including 78 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that I. japonica is sister to I. sinensis and I. yunguiensis. These results provide additional resources for the future studies on Isoetes species.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
