Summary: A recently described species, Camellia zhaiana S.X. Yang, from Guangxi, China, was proposed as critically endangered and its complete chloroplast genome was characterized in this study. Phylogenetic analysis confirmed a close relationship between C. zhaiana and C. longipedicellata. These findings support previous systematic research on C. zhaiana and advance bioinformatics of the genus Camellia.

Summary: In this study, the complete chloroplast genomes of Gentiana rigescens and G. cephalantha were sequenced. The analysis showed high similarity between the two species, but heterozygotes were found in the nuclear genomes. Phylogenetic analysis revealed that G. rigescens and G. cephalantha are closely related but undergo frequent hybridization. This poses a serious threat to G. rigescens, as hybridization and backcrossing may lead to genetic swamping and even extinction.
