In this laboratory, we try to elucidate the transport system by analyzing the intracellular transport system of plants widely from molecular to individual level, and the final goal is to understandingthebiological mechanism of plant.I am interested in the environmental response of plants and its control mechanism. I became interested in researching those widely in this laboratory.In department of Integrative Bioscience and Biomedical Engineering, there are variousstudents with diverse backgrounds from biological to engineering. For this reason, by having exchanges with various students, we can keep the motivation high, and wecan think about research from a different perspective so far.
Unlike erythrocytes, diversity in the repertoires of granulocytes, such as neutrophils, basophils, and eosinophils, has been known among more than seventy thousand of vertebrate species. In medaka fish, there is only neutrophils but basophils and eosinophils are absent in the circulation. I am studying what kind of immune response occurs in medaka. As there is little knowledge or technology about the blood of medaka, blood collection method and blood cell counting method must be established. I devise better methods while being excited.I want to be a researcher who can contribute to the development of life sciences without being bound by the species.
My research topic is the interaction between respiration and photosynthesis in algae. In photosyntheticprokaryotes, cyanobacteria, some electrons flow from the respiratory chain to the photosynthetic electron transfer chain, resulting in the induction of the decrease of photosynthetic efficiency even in the weak light and dark. In addition, the similar interaction known as chlororespiration is reported in some phototrophic eukaryotes. I am interested in the down regulation induced by the interaction, because the efficient utilization of light source maybe required under dim lightfor photosyntheticorganisms. Since theinteraction is not observed in vascular plants but widely observed in algae, the interaction between respiration and photosynthesis might be involved in the terrestrial adaptation and the evolution of photosynthetic organisms.
The theme of my research in doctor course is “Sex determination and sex differentiation in vertebrate” using Japanese wrinkled frog Glandirana rugosa. This frog have very interesting character that they have two sex determination system within one species. There are a lot of difficulty using this frog for experiment, because this frog is not laboratory animal for example mouse or xenopus, but wild animal . However, This is my attractive of research. I would like to continue to use wild animals like Japanese wrinkled frog in order to realize the research that is not realized using laboratory animals in the feature.
Iaim to clarify how nutritional status affects cognitive function from the viewpoint of individual animal and cell level using pond snail Lymnaea stagnalis.So far, changes in nutritional status have been shown to affect serotonin signaling in the brain, and it is further suggested that insulin signaling is involved in this phenomenon. In the future, I would like to approach the more specific signal crosstalk of serotonin and insulin, and the switching mechanism of learning ability due to the difference in nutritional status.
DNA is known as agenetic material that carries biological information and plays a central role in inheritance, while DNA also has the properties of polymers, and itsconformation(3D structure) also functions as a source of genetic information. Genomes harbor a great many motifs that can formunusual DNA structures.However, most of their functions have not yet been clarified.I am exploring function of unusual DNA structures from the aspects of biology, chemistry,and physics. I am engaged inthis research day and night because I deeply desireto reveal their functions. In future, I want to become ascientistwho can influencethe world.
I am exploring"the origin and evolution of digestive enzymes of carnivorous plants". Carnivorous plants have adapted themselves to the nutrient-deficient habitats. They can obtain nitrogen and phosphatefrom insects assupplementariesfor amino acid and nucleotide syntheses.Using Drosera adelae, which is a speciesof sundews, Iam examiningcharacteristics of digestive enzymes contained in the digestive fluid, their gene structures and expression profiles. So far, Ihave revealedthat defense-related proteins are used as digestive enzymes for carnivory in D. adelaeby introducingslight changes into their primary structures andgene expression mechanisms.
