"How do hearts, wings or flowers get their shape?" asks Professor Enrico Coen from the John Innes Centre. " Unlike man-made things like mobile phones or cars, there is no external hand or machine guiding the formation of these biological structures; they grow into particular shapes of their own accord." "Looking at the complex, beautiful and finely tuned shapes produced by nature, people have often wondered how they came about. We are beginning to understand the basic genetic and chemical...

Plants that can pollinate themselves are more likely to go extinct, says new study of nightshade plant family Many plants can pollinate themselves and reproduce without the aid of a mate, thanks to having both male and female parts. But the short-term perks of being able to go it alone come with long-term costs, says a new study in the journal Science. The reason is because plants that can pollinate themselves are more prone to extinction, scientists say. Flowering plants are incredibly...

Most flowering plants, equipped with both male and female sex organs, can fertilize themselves and procreate without the aid of a mate. But this may only present a short-term adaptive benefit, according to a team of researchers led by two University of Illinois at Chicago biologists, who report that long-term evolutionary survival of a species favors flowers that welcome pollen from another plant. "We've shown that a strong, short-term advantage experienced by individuals that have sex with...

Patterns of flower biodiversity point to the importance of having 'room to grow' What, in nature, drives the incredible diversity of flowers? This question has sparked debate since Darwin described flower diversification as an 'abominable mystery.' The answer has become a lot clearer, according to scientists at the University of Calgary whose research on the subject is published today in the on-line edition of the journal Ecology Letters. Drs. Jana Vamosi and Steven Vamosi of the Department...

The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non"“flowering varieties would result in an 80 percent decrease in the area covered by ever"“wet rainforest. The simulations demonstrate the importance of flowering"“plant physiology to climate regulation in...

New research confirms that early angiosperms were weedy, fast-growing Fossils and their surrounding matrix can provide insights into what our world looked like millions of years ago. Fossils of angiosperms, or flowering plants (which are the most common plants today), first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, it is thought that early angiosperms must have been weedy, fast-growing shrubs and herbs found in highly...

Findings fuel ongoing debates over different approaches to dating the tree of life Flowering plants may be considerably older than previously thought, says a new analysis of the plant family tree. Previous studies suggest that flowering plants, or angiosperms, first arose 140 to 190 million years ago. Now, a paper to be published in the Proceedings of the National Academy of Sciences pushes back the age of angiosperms to 215 million years ago, some 25 to 75 million years earlier than either...

Power struggle between genetic master switches decides stem cell fate, growth orientation in plants The first order of business for any fledgling plant embryo is to determine which end grows the shoot and which end puts down roots. Now, researchers at the Salk Institute expose the turf wars between two groups of antagonistic genetic master switches that set up a plant's polar axis with a root on one end and a shoot on the other. "In what is arguably the most important decision for a plant,...
