Abstract: | Background Inkjet micropatterning is a versatile deposition technique with broad applications in numerous fields. However, its application
in plant science is largely unexplored. Leaf expansion is one of the most important parameters in the field of plant science
and many methods have been developed to examine differential expansion rates of different parts of the leaf lamina. Among
them, methods based on the tracking of natural landmarks through digital imaging require a complicated setup in which the
leaf must remain fixed and under tension. Furthermore, the resolution is limited to that of the natural landmarks, which are
often difficult to find, particularly in young leaves. To study the fine scale expansion dynamics of the leaf lamina using
artificial landmarks it is necessary to place small, noninvasive marks on a leaf surface and then recover the location of
those marks after a period of time. |
