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 ...

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 ...

Journal of Experimental Botany, Vol. 48, No. 311 (JUNE 1997), pp. 1229-1239 (11 pages) Maize (Zea mays L.) was grown in quartz sand culture either with a normal root system (controls) or with seminal ...

The xylem is essential for transporting water across the entire plant body. Its development is heavily regulated by VND genes. Scientists report a new experimental system that shows three VND genes ...

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 ...

These are distributed differently in roots and stems. In the root, the xylem forms a central column. It forms a solid support. The phloem is towards the centre, outside the xylem. Any green part of a ...

An enzyme appears to enable Xyllela fastidiosa bacteria to infect grapevines with Pierce's disease, causing serious leaf damage as pictured here. UC Davis plant scientists have identified an enzyme ...

One useful tip to avoid food poisoning while travelling is to eat fruit you peel yourself. The thinking is that trees and plants filter the water they suck up from the ground so their fruit is ...
