چکیده انگلیسی
The most remarkable morphological specializations of mangroves are vivipary, salt secretion, and aerial roots. There has been a long debate on whether the complex traits vivipary and secreters have a single origin, the answer to which has profound implications for the mechanism of evolution in mangroves. We took a large and representative sample across mangroves and sequenced the 18S rRNA, rbcL, and matR genes. Together with the outgroups, our data yielded a high resolution phylogeny which allowed us to gain much needed insight into the distributions of the two characters and address their evolutionary origins. For each character, its ancestral state in the phylogeny was estimated by the maximum likelihood method. Overall evidence is in favor of a multiple origin for both vivipary and salt secretion in mangroves.
