Scientists have identified a crucial mechanism that allows plants to shape their vascular systems, determining whether they grow soft edible storage organs or develop the rigid woody tissue ...

Trees are by far the tallest organisms on Earth. Height growth is made possible by a specialized vascular system that conducts water from the roots to the leaves with high efficiency, while ...

Cross section of hypocotyl of 8-week-old Arabidopsis thaliana. The ovac mutant displays enhanced secondary vessel differentiation (red) at the expense of parchenchyma cells. Images A2 and B2 show the ...

New techniques allow live-observation of forming cell walls in the vascular tissue. Trees are by far the tallest organisms on Earth. Height growth is made possible by a specialized vascular system ...
