Temporal-spatial expression patterns of plastid Cpn60 genes using quantitative real-time RT-PCR. Roots and leaves were sampled from 14-d-old seedlings grown in soil at constant 27°C/light. Flag leaves and spikelets at heading stage, young panicles (2–5 cm long), and developing seeds at 10 d after pollination were sampled from paddy field. UBQ5 was internal control. Error bars indicate standard deviations; n = 3.
