dorstenia การใช้

• Recently a species of Moraceae from Kenya, " Dorstenia christenhuszii " was named after its discoverer.
• For this hypothesis to receive more credence, fossil " Dorstenia " plants in North America would be needed.
• "Dorstenia " is named in honor of the German physician and botanist Theodor Dorsten ( 1492 1552 ).
• This idea also allows for the Old World species nested within the new world by " Dorstenia " populations established in America returning to Africa by Beringia.
• Due to the small endosperm that is typical of " Dorstenia " seeds, it is unlikely that seed dispersal by animals is the reason for the new world and reemerged old world species.
• "Dorstenia " is part of the Dorstenieae tribe of the family Moraceae, and all three levels of classification are monophyletic from chloroplast and nuclear DNA phylogenies, with morphological characters that also support.
• The genus " Dorstenia ", also in the fig family ( Moraceae ), exhibits similar tiny flowers arranged on a receptacle but in this case the receptacle is a more or less flat, open surface.
• This study produced an interesting phylogeny that revealed an initial old world divergence around 112.3 mya, divergence and radiance of new world " Dorstenia " at 67.2 and 30.3 mya respectively, and an old world group nested within the new world that radiated around 13.6 mya.
• In a recent study using fossil fruits, Bayesian molecular dating, and maximum likelihood, researchers attempted to reconstruct the ancestral history of " Dorstenia " with ITS ( internal transcribed spacer ) sequences from ribosomal DNA of 35 " Dorstenia " species and seven out-group species from the different tribes within the Moraceae.

• The results of this phylogeny do not determine if vicariance or seed dispersal is the cause behind the old and new world populations of " Dorstenia "; however, it does pose several hypotheses regarding how the new world population came about as well as how three old world Dorstenia species are nested in the new world clade of the phylogeny.

• The goal was to resolve a long-standing issue within " Dorstenia " of if this genus diverged and radiated prior to the split of Africa and South American about 105 mya, and members of this genus are on separate continents by vicariance, or if this genus diverged post split and " Dorstenia " became established in the Neotropics by seed dispersal.
