A rice dominant gene, Ur1, increases spikelet number per panicle, thereby enlarging sink size. The effects of Ur1 on panicle and grain traits were examined using 'Nishihikari' (N), its Ur1 isogenic line (NU) and their F1, and the sd1-d isogenic line of Taichung 65 (d), the sd1-d-Ur1 isogenic line (u) and their F1. Ur1 increased number of primary branches per panicle (NB1), number of secondary branches per primary branch (NB2) and number of spikelets per single secondary branch (SB2).

A hollow-fiber membrane chamber (HFMC) was developed as an in situ cultivation device for environmental microorganisms. The HFMC system consists of 48 to 96 pieces of porous hollow-fiber membrane connected with injectors. The system allows rapid exchange of chemical compounds, thereby simulating a natural environment.
