New University of Arizona research indicates that leaf vein patterns correlate with functions such as carbon intake and water use -- knowledge that could help scientists better understand the complex ...

You might assume that a leaf's vein patterns fork, like tree branches splitting into twigs as they get further from the trunk. But peer carefully and you'll see that the veins make innumerable closed ...

Elastic stresses may play a crucial role in determining a leaf's venation pattern, according to a new study. Biologists have developed a model that reproduces statistical properties of venation ...

Formation of leaf vascular pattern requires regulation of a number of cellular processes, including cell proliferation. To assess the role of cell proliferation during vein order formation, leaf ...

Plant biologists are facing pressure to quantify the response of plants to changing environments and to breed plants that can respond to such changes. One method of monitoring the response of plants ...

Tree branches have inspired efficient transit networks, but a new study finds inspiration in leaves. The curvy, connected leaf veins found in some plants are an efficient way to circumvent damaged ...

University of Alberta scientists say they have determined, in part, how patterns on leaves are formed. "For years people have been trying to understand this beautiful formation," said Enrico Scarpella ...

Overexpression of SHR enhance mesophyll cell division, resulting in a substantial reduction in leaf vein density. However, exogenous auxin treatments led to an increase in leaf vein density. Notably, ...

Annals of Botany, Vol. 93, No. 2 (February 2004), pp. 149-156 (8 pages) • Background and Aims In some dicotyledonous leaves and leaflets, the secondary veins run more-or-less straight to the margins ...

Science isn't only about explaining what hasn't yet been explained. Old explanations accumulate their own inertia. It's easy to keep tweaking a familiar and trusted theory, seeking the elusive ...

You might assume that a leaf's vein patterns fork, like tree branches splitting into twigs as they get further from the trunk. But peer carefully and you'll see that the veins make innumerable closed ...
