| 内容記述 | FLO2, FLOURY ENDOSPERM 2, is highly conserved in higher plants, and rice FLO2 has been predicted to be involved in regulation of storage substance accumulation. We analyzed the function of Arabidopsis thaliana FLO2 (AtFLO2) because A. thaliana set structurally different seeds from those of rice. Although the flo2 mutant of A. thaliana showed normal germination, inflorescence and morphogenesis of flowers, peculiar phenotypes on leaves and siliques were observed, suggesting that this gene played important roles both during vegetative and reproductive stages. The mutant leaves showed decrease of chloroplast numbers, and increased total biomass with faster growth. When grown in the high luminous intensity condition, it was observed that aging events were induced. The flo2 mutant depressed transportation of photassimilates into the sink organs. In the reproductive stage, the flo2 mutant showed significantly small size siliques, invoking a reduced yield of seeds. These seeds were structurally weak, and quality of seeds was significantly lowered with reduction of seed storage accumulation. A positron-emitting tracer imaging system (PETIS) analysis detected the decreased amount of the photoassimilate transport in the flo2 mutant. Therefore, it was presumed that the phenotypes of the flo2 mutant were caused by reduced performance of translocation or transportation of the photoassimilates. Our observation suggests that AtFLO2 is strongly involved in regulation of translocation and transport of assimilates, and deeply contributes to quality control on the various processes involving substance supply or transfer, such as photoassimilation, leaf enlargement, yield of seeds in a silique, and accumulation of seed storage substances. | |||||
