Transgenic rice seeds were germinated on sterilized water containing
30 mg L−1 hygromycin and grown in soil in a greenhouse.
For analysis of growth, WT and UpReg-1 overexpressing rice (T2
generation: UpReg1-16, 2-3 and 2-19) plants were grown under
natural environmental conditions in an experimental field plot at
the National Institute of Crop Science in Suwon, Korea. 30-day-old
rice seedlings were transplanted into six rows of 25 plants per row
at a planting distance of 30 cm
×
15 cm. Twenty plants from the
middle of the central row in each plot were used for collection of
trait data. The traits measured were: culm length (CL, cm), panicle
length (PL, cm), panicle number per hill (PNPH), spikelet number
