Figure 1From: QTLs underlying natural variation of root growth angle among rice cultivars with the same functional allele of DEEPER ROOTING 1 Representative root growth angles of four cultivars grown in baskets in a greenhouse. The root growth angle (θ) of each plant was determined by measuring the angle between the soil surface (horizontal line) and the shallowest crown root. Data are means ± SD; n = 10 plants.Back to article page
