Adverse Effect of Shoot Growth on Root Growth in Rooted Cuttings of Aspen
Physiologia Plantarum, 1971AbstractIn experiments with rooted cuttings of aspen (Populus tremula L). with a small leaf area, it was found that the roots grew well as long as there was no shoot growth. The onset of shoot growth was followed by a period of decreased root growth. When the leaf area had increased sufficiently, root growth recovered.

Annual Review of Plant Physiology, 1953
The following review deals with the growth of roots in a fairly broad sense. It has been possible in a few instances only to separate from each other experimentally the different kinds of growth, i.e., cell multiplication and cell elongation. Usually growth as measured by length, weight or, less frequently, by volume of roots denotes the sum of an ...

A model is developed for the rate of elongation of a root tip in terms of the balance of pressures acting on the root. Differentials of this equation give expressions for the changes in root elongation rate with respect to soil water potential and soil mechanical resistance.

Plant Science![Figure][1] CREDIT: NASA/ IMAGE COURTESY OF ESA In the growing Arabidopsis root tip, the hormone auxin regulates cell division and differentiation from the stem cell niche. Auxin is expressed as a gradient, which peaks at the root meristem, where stem cells drive root growth.

Our interest in this subject arose from the discovery (43) of the selective herbicides, 3,5-diiodo-4-hydroxybenzonitrile (ioxynil) and the dibromo derivative (bromoxynil), both of which are widely used in agriculture. This discovery stimulated research on their mode of action and metabolism, and investigations on chemical structure in relation to ...

DEVELOPMENT Adult hair follicles sustain repeated cycles of hair loss and regrowth. Stem cells reside within a small niche, called the bulge, located in the upper part of the hair follicle. These stem cells are responsible for driving this cycle of growth and can repopulate follicles and surrounding epidermis damaged by wounding.

Post-industrial cities are characterized by population, economic and infrastructure decline. Yet within these cities, there is a sample of communities that are resilient. Resilience is a measure of sustainability, that represents a community's ability to respond to, withstand and recover from adversity. In St. Louis, Todd Swanstrom (CBN) has identified
