If plants could talk, what would they say?
If plants could speak they will boast about being part of remedies such as the common aspirin to a leukaemia drug derived from the rosy periwinkle. view more (2009-03-06)
Plants recognize their siblings, biologists discover
The next time you venture into your garden armed with plants, consider who you place next to whom. It turns out that the docile garden plant isn't as passive as widely assumed, at least not with strangers. view more (2007-06-14)
Destruction of a GM barley research trial at the John Innes Centre
Over the weekend of 15-17th June 2001 a small research plot of genetically modified (GM) barley plants at the John Innes Centre*, Norwich (JIC), was destroyed by trespassers. "This trial was part of a publicly funded programme to provide important information to the UK Food Standards Agency" said Professor Chris Lamb (Director of JIC). "The John... view more...

Gardeners urged to help stop spread of invasive plants
Invasive alien plants are causing havoc in our natural landscape, but gardeners can play a key part in stopping their spread. That`s the view of Imperial College Wye which will be exhibiting at this year`s Chelsea Flower Show, opening 20 May. The College stand (LL23) will outline the threat caused by alien or non-native plants introduced... view more... (2002-05-09)
Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters, Schippers, Lürling and Scheffer of the Wageningen... view more... (2004-05-13)
A world ruled by fungi
The catastrophe that extinguished the dinosaurs and other animal species, 65 million years ago also brought dramatic changes to the vegetation. In a study presented in latest issue of the journal Science, the paleontologists Vivi Vajda from the University of Lund, Sweden and Stephen McLoughlin from the Queensland University of Technology,... view more...

Stanford researchers investigate how plants adapt to climate
How many mouths does a plant need in order to survive? The answer changes depending on climate, and some of the decisions are made long before a new leaf sprouts. view more (2008-11-25)
Lotus effect shakes off dirt
The lotus - a flowering wetland plant native to Asia - may not at first glance be of interest to the nanotechnologist. But researchers at German chemical company BASF are developing a spray-on coating that mimics the way lotus leaves repel water droplets and particles of dirt. The story is reported on nanotechweb.org, the Institute of Physics'... view more... (2002-11-08)
Old leaves need to die in time or they will bring a plant down
In a study from the November issue of The American Naturalist, researchers Alex Boonman and co-workers from the Netherlands show that it is beneficial for plants growing in a dense stand to shed their oldest, lower leaves once these become shaded. view more (2006-11-02)
Systems biology approach identifies nutrient regulation of biological clock in plants
Using a systems biological analysis of genome-scale data from the model plant Arabidopsis, an international team of researchers identified that the master gene controlling the biological clock is sensitive to nutrient status. view more (2008-03-17)
Ecologists give evidence to climate change inquiry
The UK should use its presidency of the G8 and EU to move forward international action to analyse future risks due to climate change and develop and implement evidence-based adaptation strategies for coping with the immediate impacts of climate change, the British Ecological Society has urged. Giving evidence to the House of Commons Environment,... view more... (2004-12-08)
Biocontrol Insect Exacerbates Invasive Weed
Biocontrol agents, such as insects, are often released outside of their native ranges to control invasive plants. But scientists in Montana have found that through complex community interactions among deer mice, native plants and seeds, the presence of an introduced fly may exacerbate the effects of the invasive plant it was meant to control. view more (2008-09-04)
Discovery in plant virus may help prevent HIV and similar viruses
In a study that could lead to new ways to prevent infection by human immunodeficiency virus (HIV) and similar organisms, Purdue University researchers have been able to genetically modify a plant to halt reproduction of a related virus. view more (2007-08-01)
Ozone depletes oil seed rape productivity
High ozone conditions cause a 30% decrease in yield and an increase in the concentration of a group of toxic compounds within oilseed rape plants. view more (2009-06-29)
Low Level Herbicide Use Can Damage Potato Reproduction
Currently, plant testing in the United States to determine potential ecological risks from chemical pesticides to nontarget plants requires two tests, both of which use immature plants. view more (2009-01-07)
The conservation lens
The definition of conservation priorities for biodiversity often focuses only on the numbers of vertebrate animals and seed plants in the northern hemisphere or in the tropics. view more (2007-10-25)
Evolutionary Biology Research on Plant Shows Significance of Maternal Effects
When habitat changes, animals migrate. But how do immobile organisms like plants cope when faced with alterations to their environment? This is an increasingly important question in light of new environmental conditions brought on by global climate change. view more (2007-11-16)
Blue tits love the smell of perfumed nests!
French birds love the smell of perfumed nests. In an article published this month in Ecology Letters, scientists from the Centre National de Recherche Scientifique report that a small cavity-nesting bird on the island of Corsica, the blue tit, adorns its nests with fragments of strongly perfumed plants, including lavender and mint. The chemical... view more... (2002-07-11)
Scientists propose the creation of a new type of seed bank
While an international seed bank in a Norwegian island has been gathering news about its agricultural collection, a group of U.S. scientists has just published an article outlining a different kind of seed bank, one that proposes the gathering of wild species -- at intervals in the future -- effectively capturing evolution in action. view more (2008-10-16)
Flowers' fragrance diminished by air pollution, University of Virginia study indicates
Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates. view more (2008-04-11)
