The entire cap can be removed from the apex of the primary root of Zea mays. When this is done the nuclei of cells of the quiescent centre are stimulated to synthesize DNA and subsequently enter ...

The roots of a plant are constantly growing, so that they can provide the plant with water and minerals while also giving it a firm anchor in the ground. Responsible for these functions are ...

A multidisciplinary research team, led by the CSIC biologist at CRAG, Ana I. Caño Delgado, and the physicist from the University of Barcelona, Marta Ibañes, has discovered that two plant stem cell ...

This is a preview. Log in through your library . Abstract The proportion of cells that divide in four regions of the root meristem of Zea mays has been determined by an analysis of its cells ...

In plant roots, different cell types are organized in a well-defined pattern: each cell knows exactly where it is and what it should do. A molecule that tells cells where they are has now been ...

Plant stem cells, as in animals, are maintained in specialized microenvironments, which are known as stem cell niches, where local signals from organizer cells act to prevent stem cell differentiation ...

Researchers have discovered that two proteins, which are involved in the control of stem cells' division in plant roots, need each other for these cells to function properly. The study combines ...
