Project description:Mangrove Kandelia obovata, an important coastal shelterbelt and landscape tree, is distributed in tropical and subtropical shores and likely delimited in the latitudinal range by varying sensitivity to cold. Here, we explored the temporal variations in physiological status and transcriptome profiling of K. obovata under natural frost conditions at ~32oN, as well as the positive role of exogenous abscisic acid (ABA) in cold resistance.
