2010-09-02Ancient Genome Duplications During the Evolution of Kiwifruit (Actinidia) and Related EricalesPaleopolyploidy refers to ancient genome duplications which occurred at least several million years ago. Due to functional redundancy,genes are rapidly silenced and/or lost from the duplicated genomes. The most recent event is consistent with previous cytological work on kiwi while the older event is shared by the common ancestor of Camellia and... Paleopolyploidy refers to ancient genome duplications which occurred at least several million years ago. The genome doubling event could either be an autopolyploidy or an allopolyploidy. Due to functional redundancy, genes are rapidly silenced and/or lost from the duplicated genomes. Most paleopolyploids, through evolutionary time, have lost the...Read More -

2010-07-28Mussaenda Pubescens (Rubiaceae): A Case on the Evolution of Dioecy from Stigma-height DimorphismHerkogamy is a common strategy employed by hermaphroditic angiosperms to reduce self interference within flowers. Stigma-height dimorphism is a less well-known reciprocal herkogamy. In species with stigma-height dimorphism,individuals within a population have two floral-morphs and flowers of different morphs differ significantly in style length ...

2010-07-22Research Progress on Mutualism of Figs and Fig WaspsFigs and their pollinating wasps constitute one of the classic examples of pollination mutualism and appear to present one of the best cases of co-evolution known. Figs are completely dependent on fig wasp for pollen dispersal and the production of viable seeds. So the seeds are more effective to gene flow among populations for dioecous figs We ... Figs (Ficus species, Moraceae) are defined by a unique enclosed inflorescence, the syconium, which are also the arena for interactions with fig wasps. Figs and their pollinating wasps constitute one of the classic examples of pollination mutualism and appear to present one of the best cases of co-evolution known. Figs are completely dependent on...Read More
