Comparative Plastome Analysis Between Endangered Mangrove Species and Relatives Provides Insights into Its Origin and Adaptive Evolution.

is a typical true mangrove species with great ecological and medicinal values. However, it has become endangered in China. Moreover, because of the similar morphology and distribution, it is commonly confused with the congeneric mangrove species, , which poses challenges to the protection and proper medicinal utilization of .

transcriptome analysis of high-salinity stress-induced antioxidant activity and plant phytohormone alterations in .

has a strong salt tolerance and can grow in saline and alkaline coastal and inland habitats. This study investigated the physiological and molecular responses of to high salinity by analyzing the changes in plant phytohormones and antioxidant activity, including their differentially expressed genes (DEGs) under similar high-salinity conditions. High salinity significantly affected proline (Pro) and hydrogen peroxide (HO) in seedlings, increasing Pro and HO contents by 290.
