Study of plant hormone could have far-reaching implications for cell biology and disease research A recent Van Andel Research Institute (VARI) study published in the journal Science investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the development of new drugs for a variety of diseases. The study builds on earlier work by the same team of investigators at VARI...

Natural growth regulator found to increase or decrease growth, depending on application Natural products marketed as plant growth enhancers are becoming increasingly sought-after. Many of these products, typically produced by small companies with limited research capabilities, have not been tested in farm trials, nor have claims about product effectiveness been documented by scientific data. Researchers from the University of Copenhagen investigated the growth regulatory effect of Tea Seed...

A mechanism for stabilizing the development of the plant organism During the development of organisms, a particular event repeatedly occurs: a signal appears temporarily, but the processes it triggers must be maintained "“ for example, when the fate of cells in the embryo is established. The plant hormone auxin plays an important role as a signaling molecule during embryo development of the thale cress (Arabidopsis thaliana), a model plant widely used in genetic studies. Researchers...

A Purdue University scientist and researchers in Japan have produced a new class of improved plant growth regulators that are expected to be less toxic to humans. Angus Murphy, a professor of horticulture, said the growth inhibitors block the transport of auxin, a plant hormone that, when transported throughout the plant, controls growth processes. Current growth regulators that inhibit auxin transport are inefficient because they also have hormonelike activity or affect other important plant...

Ben-Gurion University of the Negev researchers have developed techniques to manipulate root development functionality that can help plants better adapt to hostile growing environments. In a recent paper published in the prestigious journal The Plant Cell, BGU researchers were able show that by manipulating a specific gene they could impact lateral root growth. Lateral root (LR) development is a highly regulated process that determines a plant's growth and ability to adapt to life in different...

Plants are very sensitive to light conditions because light is their source of energy and also a signal that activates the special photoreceptors that regulate growth, metabolism, and physiological development. Scientists believe that these light signals control plant growth and development by activating or inhibiting plant hormones. New research from Carnegie plant biologists has altered the prevailing theory on how light signals and hormones interact. Their findings could have implications...

Scientists have known for some time how important plant steroids called brassinosteroids are for regulating plant growth and development. But until now, they did not know how extensive their reach is. Now researchers, including Yu Sun and Zhi-Yong Wang at Carnegie's Department of Plant Biology, have identified about a thousand brassinosteroid target genes, which reveal molecular links between the steroid and numerous cellular functions and other hormonal and light-activated chain reactions....

Tinkering with a single gene may give perennial grasses more robust roots and speed up the timeline for creating biofuels, according to researchers at the Duke Institute for Genome Sciences & Policy (IGSP). Perennial grasses, including switchgrass and miscanthus, are important biofuels crops and can be harvested repeatedly, just like lawn grass, said Philip Benfey, director of the IGSP Center for Systems Biology. But before that can happen, the root system needs time to get established....

Greenhouse plant growers can substitute rice hulls for perlite in their media without the need for an increase in growth regulators, according to a Purdue University study. Growing media for ornamental plants often consists of a soilless mix of peat and perlite, a processed mineral used to increase drainage. Growers also regularly use plant-growth regulators to ensure consistent and desired plant characteristics such as height to meet market demands. Organic substitutes for perlite like tree...
