1.Analysis of molecular mechanism about abscission layer formation and degradation in seed shattering in rice<\/strong><\/h2>\n\n\n\n

\u3000Seed shattering is a trait of seed shedding from panicles (Fig.A). It is an important trait as a breeding strategy by the spread of seeds in nature. On the other hand, when considered as crops, strong seed shattering leads to a reduction in crop yield. Therefore, it is considered to be one of important agricultural traits even today. Our laboratory has isolated seed shatteirng gene qSH1<\/em> in rice and it is clear that it is essential for abscission layer formation (Fig.B,C) In addition, a candidate gene downstream of qSH1<\/em> was found by performing a site-specific microarray analysis using the laser microdissection method. Furthermore, we are searching for new genes by analyzing mutant strains using gamma ray irradiation.<\/p>\n<\/div>\n\n\n\n

2. Characteristics extraction of leaves in rice using image analysis<\/strong><\/h2>\n\n\n\n

\u3000In the early growth of plants, chemical energy obtained by photosynthesis is consumed to maintain life activities of plants by respiration and the like. The surplus is used for the formation and growth of new plants. Newly formed leaves will also photosynthesize and contribute to further individual growth. In this way, initial growth exhibits a complex positive feedback aspect. Therefore, slight differences in the natural environment during initial growth can lead to large differences in individual size. In our laboratory, we used a measurement system (Fig. D, E) for nondestructively monitoring plant growth (growth rate) of plants under natural environment. We are aiming at the production of high CO2-absorbing rice lines with rice as a crop material as an indicator of improvement of plant growth rate.<\/p>\n<\/div>\n\n\n\n

3. Selection of rice variety for rice flour and challenge to application<\/strong><\/h2>\n\n\n\n

\u3000In recent years the price of wheat has soared, the use of rice as rice flour, improvement of food self-sufficiency rate, effect of eliminating cultivation abandonment area is beginning to be expected. However, since wheat flour and rice flour have various components such as amylose content and protein content, it is essential to develop and use varieties corresponding to each application. Therefore, selection and characterization of rice varieties suitable for foods using rice flour are being conducted.<\/p>\n<\/div>\n\n\n\n
