Dioscorea zingiberensis (Dioscoreceae) is an important medicinal plant endemic to China. Here, its chloroplast genome sequence is reconstructed from the whole-genome Illumina sequencing data. The circular genome is 153,970 bp in length, and comprises a pair of inverted repeat (IR) regions of 25,491 bp each, a large single-copy (LSC) region of 83,950 bp and a small single-copy (SSC) region of 19,038 bp. The chloroplast genome contains 132 genes, including 86 protein-coding genes (79 PCG species), 8 ribosomal RNA genes (four rRNA species) and 38 transfer RNA genes (30 tRNA species). Out of these genes, 10 harbor a single intron, and 7 contain a couple of introns. The overall A + T content of the whole genome is 62.8%, while the corresponding values of the LSC, SSC and IR regions are 64.9%, 68.8% and 57.0%, respectively.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
