The establishment of localized auxin gradients plays a central role in developmental patterning in plants. Auxin levels and responses have been shown to increase with temperature although developmental patterning is not affected. This suggests the existence of a homeostatic mechanism that ensures that patterning occurs normally over a range of temperatures. We recently described the cloning and...

microfabrication applications, it is widely used to transfer the designed patterns from an etching mask to the substrate. When the sample is immersed into the etching bath, the etchant only contacts and reacts with the substrate surfaces where are uncovered by the etching mask. The suitable materials for the mask can be polymers or other materials such as photoresist, SU-8,SiO2 andSi3N4, which ...
