Fig. 1From: De novo transcriptome sequencing of Impatiens uliginosa and the analysis of candidate genes related to spur developmentA Average growth curve of spur of I. uliginosa. The red dashed line indicates the boundary between the three development stages B Spur in the early stage, showing a straight appearance (left); Spur in the middle stage, producing an inward curve (middle); Spur at anthesis (right)Back to article page
