LeafNet for automatic phenotyping of the leaf epidermis
The Plant Cell: In a NutshellLi et al. developed a new tool called LeafNet for segmenting and quantifying stomata and pavement cells.
Background: Stomata are microscopic openings in the leaf epidermis that allow for oxygen and carbon dioxide exchange between a plant and the atmosphere. The phenotypes of stomata and the surrounding…
