Fig. 6From: The role of JrLACs in the lignification of walnut endocarpWalnut endocarp lignification process. The upper side shows a transverse cut of the fruit and the lower side shows a longitudinal cut of the fruit. The lignin in endocarp is stained pink based on Wiesner reaction. The fruit shells were not lignified until 38 days after flowering and began to lignify after 44 days after floweringBack to article page
