Title: Environmental Metagenomics for Monitoring Dynamic Changes of Marine Microorganism Diversity

 

Abstract:

Environmental metagenomics is a genomic approach in which genomic fragments of any species contained in environmental samples such as a bottle of sea water and a cup of land soil are sequenced without morphological identification of those species in order to observe ecological features of a diversity of microorganisms.  When this kind of metagenomics is applied for studies of marine microorganism diversity in particular, species composition of microorganisms obtained can be used for environmental evaluation of the sea water in addition to understanding of dynamic features of marine microorganism diversity. 

 

Here, we present the progress of our projects in which we are now conducting an environmental metagenomics approach for understanding of marine microorganism diversity in the sea surrounding the Japan islands.  In particular, one of important missions in the present projects is to search for rhodopsin genes of protists in the sea water.  Because we found in our earlier work that a camera-eye like structure of dinoflagellates contains a bacterial type of rhodopsin genes, we would like to know how widely rhodopsin genes  are distributed among protists in order to understand the evolutionary origin of camera-eye like structure.  I would make the progress report of our research.

Title: The Genetic Basis of Mimetic Variation: from butterflies to bumble bees

 

Abstract:

Mimetic systems comprise some of the most astounding phenotypic radiations in nature. The repeated evolution of color patterns in these systems provides numerous natural replicates for understanding the genetic basis of adaptation. This talk will highlight recent discoveries on the genetic basis of mimetic wing pattern variation in the Heliconius butterflies, a phenotypically diverse model system for Müllerian mimicry. These genes are targeted using microarrays, transcriptome sequencing, large scale genome resequencing, and a combination of genomic, population genetic, and phylogenetic techniques. This research is highlighting how major developmental genes can be coopted for new functions and revealing the evolutionary processes underlying phenotypic replication in nature. The lineage demonstrates instances of repeated color pattern acquisition involving sorting of ancestral variation, adaptive introgression, and independent evolution. The remainder of the talk will highlight a new system for studying the genetic basis of mimicry and adaptive variation - the bumble bees – that are remarkably analogous to these butterflies.
