Analyse de la courbure d'un sépale d'Arabette des dames

Analysing the curvature of a sepal of thale cress (arabidopsis thaliana), using the 3D MorphoGraphX imaging software solution. The intensity of the surface curvature is represented using a colour scale, with blue-green indicating a more pronounced curvature than red. Note that the sepal is relatively uniformly curved, except at the two ends, where it curves more sharply. The purpose of this visual representation is to yield a method for quickly and simply quantifying the shape and curvature of sepals. This will enable researchers to compare normal sepals with sepals on mutant plants (in which certain genes have been destroyed), and hence identify genes that control sepal shape.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
