Lignin biosynthesis is an essential physiological activity of vascular plants if they are to survive under various environmental stresses on land. The biosynthesis of lignin proceeds in the cell wall ...

Owing to recent advances, plant vascular developmental can now be described from early specification during embryogenesis up to late differentiation events. Plant vascular tissues display both ...

Shoot apical meristems produce stem tissues, produce leaves, and produce flowers. Cell proliferation characteristics of meristems are dependent upon cell maturation processes and the functions of ...

In a new twist on zombie botany, Harvard University physiologists have found that the pipes in a plant’s water plumbing can regulate the flow speed, despite the disability of being dead. The stack of ...

Plants transport water in pipe-like structures made of dead and empty cells within a vascular tissue called xylem. A researcher concludes in his doctoral dissertation that different cell types work ...

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 ...

Asymmetrically transported auxin-efflux carriers cause a polarized flow of auxin, which leads to the formation of continuous columns of procambial cells. In addition, one or more ...

Towering redwoods and lanky jungle vines hoist water from the soil to their lofty leaves through a tubelike tissue called the xylem. In early plants, which reached just a few centimeters and lived ...
