One goes up... and one goes down. I was a college freshman in Botany 101 when I first learned about xylem and phloem, the two transport tissues which carry water and nutrients up and down a tree's ...

Most of the businesses located along Canyon Road are devoted to art or dining. The owners of a new enterprise along that historic street are trying to introduce horticulture to the mix. Beth Succop ...

Plant and Soil, Vol. 155/156, Selected papers from the PROCEEDINGS OF THE TWELFTH INTERNATIONAL PLANT NUTRITION COLLOQUIUM (October 1993), pp. 273-276 (4 pages) Xylem sap of sinker (tap) root, cluster ...

Journal of Tropical Ecology, Vol. 29, No. 6 (NOVEMBER 2013), pp. 467-476 (10 pages) We documented one of the most species-rich assemblages of tropical rain-forest Auchenorrhyncha, comprising 402 ...

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.

Sieve elements are a key component of phloem, the conductive tissue through which plants transport carbohydrates and a wide range of signalling molecules. Elongated cylindrical cells are capped at one ...

You probably don’t think you need a botany lesson when all you want to know is how to keep your Christmas tree fresh this season. But explaining a few things might make the whole process make sense.

When plants evolved a vascular system containing cells that facilitate the transport of water and nutrients, this not only allowed them to conquer land, but also provided the structural stability that ...

Crops worldwide are increasingly vulnerable to pandemics, as diseases hitch rides on global flows of people and goods, hopping from continent to continent. Phloem diseases such as citrus greening are ...

Researchers have combined traditional genetic approaches with 3-D reconstructions from scanning electron microscopy to discover and characterize genes regulating the development of plant sieve ...
