Fig. 3From: Comparative fiber property and transcriptome analyses reveal key genes potentially related to high fiber strength in cotton (Gossypium hirsutum L.) line MD52neComparisons of fiber maturity ratios of mature fibers between MD52ne and MD90ne measured by image analysis microscopy. Circularity (θ = 4πA/P2) representing the degree of fiber cell wall thickness was calculated from average wall area (A) excluding lumen and perimeter (P) of cross-sections of 300 fibers. The maturity ratios between MD52ne (0.948 ± 0.010) and MD90ne (0.971 ± 0.033) calculated from the circularities showed no significant variation (p-value, 0.519). A scale bar represents 10 μm.
