Table 1 Agronomic traits of TNG67 and Ubi:OsMADS45 transgenic rice plants

From: Ectopic expression of OsMADS45 activates the upstream genes Hd3a and RFT1 at an early development stage causing early flowering in rice

  1. a The plant number of TNG67 was 27, 45OX-1 was 15, 45OX-2 was 13, 45OX-4 was 20, and 45OX-5 was 20.
  2. b Heading date was the date when the panicles protruding from the flag leaf sheath.
  3. c Plant height and total tiller number were measured on 104 DAI.
  4. d Fertility rate was the percentage of spikelets that set fertile seeds.
  5. e Weight of one thousand seeds (WTS) was the weight counted with 50 seeds and multiplied by 20.
  6. f Grain yield was the total weight of grains produced from one plant.
  7. g Shoot dry weight was the weight of the up-ground part of rice without the grains.
  8. h Photosynthetic rate (PR) was measured at noon on 68 DAI.
