Abstract:

Kandelia obovata Sheue, Liu & Yong, a mangrove species which distributed in tropical, subtropical coastal and estuarine intertidal, has important ecological functions in coastal ecosystems. Here, we reviewed several aspects of the recent research progress in molecular biological studies of K. obovata. We focused the phylogeography and genetic diversity of this species by several types of molecular markers, proteome analyses based on two-dimensional electrophoresis platform accomplished for this species, and functional genes isolated under non-biotic stress environment. Finally, based on the current research progress, we proposed some orientations for future molecular biological research on K. obovata.
