Photoselective film proves effective for controlling height in potted gardenia plants
To grow the high-quality potted plants preferred by consumers, many growers use chemical "regulators" designed to affect plant growth and development. view more (2009-05-04)
Modified crops reveal hidden cost of resistance
Genetically modified squash plants that are resistant to a debilitating viral disease become more vulnerable to a fatal bacterial infection, according to biologists. view more (2009-10-27)
Who influences purchases of native plants?
Native plants are a growing niche market in the southeastern United States. Researchers have documented recent trends toward increased interest in native plants by landscape architects, wholesale and retail nursery owners, and home gardeners. view more (2009-03-26)
Billion-year revision of plant evolution timeline may stem from discovery of lignin in seaweed
Land plants' ability to sprout upward through the air, unsupported except by their own woody tissues, has long been considered one of the characteristics separating them from aquatic plants, which rely on water to support them. view more (2009-01-27)
Greener offices make happier employees
According to the 2000 census, Americans office workers spend an average of 52 hours a week at their desks or work stations. view more (2008-05-20)
Greening university classrooms
In today's frenetic world, many urban dwellers spend more than 80% of the day indoors. Bringing nature in to living spaces by enhancing homes and offices with ornamental plants has become another popular facet of the move to "green" our lives. view more (2009-09-04)
Insect warning colors aid cancer and tropical disease drug discovery
Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama. view more (2008-07-09)
Female Plant 'Communicates' Rejection or Acceptance of Male
Without eyes or ears, plants must rely on the interaction of molecules to determine appropriate mating partners and avoid inbreeding. view more (2008-10-24)
Silence please
Researchers at Cambridge University have been studying the process of gene silencing in transgenic plants, and have cloned a genetic modifier that could reduce transgene instability. Dr Ian Furner will be presenting the results of the study at the Society for Experimental Biology conference on Monday 8 April. view more (2002-04-04)
Why does an anti-anthrax drug kill plants too?
Scientists at the John Innes Centre (JIC), Norwich (1) have today reported that a very successful antibiotic, which is harmless to humans but lethal to most bacteria, also kills plants. They have found that an enzyme, which is an important target for several families of antibiotics and was thought to exist only in bacteria, is also present in... view more... (2004-05-12)
The evolutionary foundation of genomic imprinting in lower vertebrates
A Chinese scientist group working in College of Life Science, Zhejiang University, has shown that, as mammalian Igf2 CpG island, goldfish Igf2 CpG island has a parental differentially methylated region (DMR). view more (2009-05-18)
'Natural' nitrogen-fixing bacteria protect soybeans from aphids
An invasion of soybean aphids poses a problem for soybean farmers requiring application of pesticides, but a team of Penn State entomologists thinks a careful choice of nitrogen-fixing bacteria may provide protection against the sucking insects. view more (2009-04-15)
Why Plants Talk To Insects - New Research from Imperial At Chelsea Flower Show (22-25 May)
Why talking to insects is so important to a plant's well-being is the theme of an unusual display at this year's Chelsea Flower show (22-25 May). The display, jointly staged by Imperial College at Wye and the ICI subsidiary, Quest International, will show how plants use scent and colour to attract helpful insects and to repel unwelcome herbivores.... view more...

Plants can be used to study how and why people respond differently to drugs
While prescription medications work successfully to cure an ailment in some people, in others the same dose of the same drug can cause an adverse reaction or no response at all. view more (2007-09-27)
Gardens in space
A model of a system for growing plants to plan biological experiments in space has just left the company of ROVSING, in Ballerup near Copenhagen, on its way to ESA's European Space Research and Technology Centre (ESTEC) in the Netherlands. The full name of this experiment reference model is European Modular Cultivation System Experiment... view more... (2002-05-13)
Behavior modification could ease concerns about nanoparticles
In an advance that could help ease health and environmental concerns about the emerging nanotechnology industry, scientists are reporting development of technology for changing the behavior of nanoparticles in municipal sewage treatment plants - their main gateway into the environment. view more (2009-11-12)
Food safety begins as vegetables grow
Monitoring vegetables while they are growing is crucial in the prevention of contamination of fresh produce with harmful bacteria such as E. coli and Salmonella, say plant pathologists who are members of The American Phytopathological Society (APS). view more (2007-06-12)
John Innes Scientists Scoop Gold Medal at Chelsea Flower Show
The exhibit is a "fashion show" which explains how jumping genes, virus disease infection and bizarre chimeras cause the beautiful foliage and flowers we admire in plants. The display features a collection of beautiful common and unusual plants as "models" on the fashion catwalk. view more (1999-05-25)
Columbine flowers develop long nectar spurs in response to pollinators
In flowers called columbines, evolution of the length of nectar spurs--the long tubes leading to plants' nectar--happens in a way that allows flowers to match the tongue lengths of the pollinators that drink their nectar, biologists have found. view more (2007-06-08)
Newly Compiled Online Bee Checklist Allows Biologists To Link Important Information About All Bee Species
n time for National Pollinator Week, June 22 through June 28, biologists have completed an online effort to compile a world checklist of bees. They have identified nearly 19,500 bee species worldwide, about 2,000 more than previously estimated. view more (2008-06-19)
