The red alga, Porphyra yezoensis is used for laver farming. In red algae including P. yezoensis, the most abundant pigments are phycobilins bound to phycobilisomes, light-harvesting complexes in chloroplast (Fig. 1). It is known that nutrient-deficiency induces the phycobilisome degradation, resulting bleaching (Fig. 2).
To develop stress resistant strains of in P. yezoensis, two research projects are proceeded in our laboratory.
We are also studying the regulation of the expression of genes involved in oxidative stress responses and secondary metabolite biosynthesis, using marine algae, moss plants and seed plants.
