Table 1 Morphological comparison of leaves and roots in nontransgenic (NT) and GA2ox6-OX transgenic lines

From: Phalaenopsis orchid miniaturization by overexpression of OsGA2ox6, a rice GA2-oxidase gene

 NT1-1a3-23-33-4
Leaf lengthb (cm)17.6 ± 3.25.3 ± 1.0**6.8 ± 0.5**5.8 ± 0.5**7.9 ± 0.3**
Leaf widthc (cm)6.2 ± 0.96.0 ± 0.65.2 ± 0.55.5 ± 0.45.8 ± 0.3
Leaf L/W ratiod2.9 ± 0.90.9 ± 0.1**1.3 ± 0.2**1.1 ± 0.1**1.4 ± 0.1**

  1. Three plants each from the NT line and four GA2ox6-OX transgenic lines (#1-1, #3-2, #3-3 and #3-4) were measured and compared
  2. a Plants of line #1-1 were grown in 9 cm pots at a relative early stage (Additional file 1: Fig S5). Others were grown in 10.5 cm pots
  3. b Leaf length average ± SE of the longest leaf from 3 individual plants
  4. c Leaf width average ± SE of the same longest leaf from the above 3 individual plants
  5. d Ratio of leaf length to leaf width
  6. e Root length average ± SE of the longest root from 3 individual plants
  7. f Root width average ± SE of the thickest root from 3 individual plants
  8. ** Average ± SE (n = 3) showed a significant difference from the NT control with a p-value < 0.01
