Researchers report some corn plants are genetically predisposed to develop longer, less constricted water-conducting tissues ...

Xylem vessel pits are tiny openings on the cell wall of water-conducting cells—with pit geometry influencing crop yield through its effect on plant hydraulics and nitrogen transport. Researchers from ...

Cross section of Arabidopsis thaliana hypocotyl showing xylem tissue patterning formed by two different cell types – xylem vessels (red) and xylem parenchyma cells. SR2200 and Fuchsin staining of ...

A study is reframing a fundamental question in plant evolution: What made trees possible? Researchers from Cal Poly Humboldt, ...

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 ...
