  1. Mean values ± the standard error of 15 independent plants is indicated. Statistical analysis was conducted using Student’s t-test (p < 0.05). Asterisk denotes a statistically significant difference in the total dry matter production of the above-ground section, brown rice yield, total spikelet number per unit land area, single grain weight of brown rice, and the ratio of filled spikelets between the wild-type and RBCS-sense rice plants. Values in parentheses indicate the percentage of the value of the wild-type rice plants. The abbreviations stand as follows: “RBCS-sense”; transgenic rice plants overproducing Rubisco, “Wild”; wild-type rice plant.
