... stem elongation has been found to primarily involve cell elongation. Two ecotypes –the alpine and the prairie, show contrasting degrees of stem elongation. The alpine plants from an open alpine habitat have a short stem ... essentially blind to this signal. However, low blue light treatments elicit a strong elongation response in both ecotypes. This then constitutes a good comparative system in which ...
