How plants remember winter, in order to flower in spring
Scientists at the John Innes Centre (JIC) Norwich (1), have discovered the molecular change that allows plants to remember winter. Many plants need a cold period (3-8 weeks at 4o - 8oC) early in their growth to stimulate them to flower, this is called vernalisation, and without a suitable cold treatment flowering is delayed. JIC scientists have... view more... (2004-01-06)
Plants take a hike as temperatures rise
Plants are flowering at higher elevations in Arizona's Santa Catalina Mountains as summer temperatures rise, according to new research from The University of Arizona in Tucson. view more (2009-02-10)
Annuals converted into perennials
Annual crops grow, blossom and die within one year. Perennials overwinter and grow again the following year. The life strategy of many annuals consists of rapid growth following germination and rapid transition to flower and seed formation, thus preventing the loss of energy needed to create permanent structures. view more (2008-11-10)
Desert dust alters ecology of Colorado alpine meadows
Accelerated snowmelt--precipitated by desert dust blowing into the mountains--changes how alpine plants respond to seasonal climate cues that regulate their life cycles. view more (2009-06-30)
Researcher discovers pathway plants use to fight back against pathogens
Plants are not only smart, but they also wage a good fight, according to a University of Missouri biochemist. Previous studies have shown that plants can sense attacks by pathogens and activate their defenses. view more (2008-04-01)
Mitochondrial genes move to the nucleus
Why mitochondrial genes ditch their cushy haploid environs to take up residence in a large and chaotic nucleus has long stumped evolutionary biologists, but Indiana University Bloomington scientists report in this week's Science that they've uncovered an important clue in flowering plants. view more (2007-03-23)
The shape of allergy - what makes an allergen an allergen
An enduring mystery for allergy researchers has been the unpredictable distribution of allergens in plants. For example, being allergic to birch pollen can predispose a person to allergy from distantly related plant foods such as celery, apple or soy. view more (2005-01-07)
Predators: an overlooked player in plant-pollinator relationships
Biologists have long recognized that predators can help to shape ecological communities -- wolves promote the growth of young trees through predation on moose, otters keep kelp forests thriving by preying on sea urchins, etc. Yet we have seldom considered the consequences of predation on animals that help plants reproduce. Predation on pollinators... view more... (2003-08-13)
Green algae -- the nexus of plant/animal ancestry
Genes of a tiny, single-celled green alga called Chlamydomonas reinhardtii may contain scores more data about the common ancestry of plants and animals than the richest paleontological dig. view more (2007-10-12)
Killer bees may increase food supplies for native bees
Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the... view more...

Important gene controlling tree growth and development found
Scientists at the UmeĆå Plant Science Centre (UPSC) and the Swedish University of Agricultural Sciences (SLU) report today about a breakthrough in our understanding of how the growth and development of forest trees is controlled. view more (2006-05-05)
Research discovers oldest bee, evolutionary link
Researchers at Oregon State University have discovered the oldest bee ever known, a 100 million year old specimen preserved in almost lifelike form in amber, and an important link to help explain the rapid expansion of flowering plants during that distant period. view more (2006-10-26)
Growing crops to cope with climate change
Scientists at the UK's leading plant science centre have uncovered a gene that could help to develop new varieties of crop that will be able to cope with the changing world climate. view more (2006-01-20)
New genetic model predicts plant flowering in different environments
It has been known for some time that plants respond to environmental cues that guide their flowering. Chief among these signals are light, temperature and vernalization, when flowering is promoted by prolonged exposure to cold temperatures. view more (2009-01-16)
Arctic spring comes weeks earlier than a decade ago
In the Earth's cold and icy far north, the harsh winters are giving way to spring weeks earlier than they did just a decade ago, researchers have reported in the June 19th issue of Current Biology, published by Cell Press. view more (2007-06-19)
Scientists discover that ancient genes dictate flowering, fall bud set
It often requires many years of growth before a tree is ready to flower - a delay that makes tree breeders impatient. Now, scientists at universities in Sweden and the United States have discovered genes that are responsible for initiation of flowering. view more (2006-05-05)
ON TRAILS OF ANCIENT SEA GRASSES
Paleobotanists from St. Petersburg have found that ancestry of sea grasses had come to sea from desert 40 million years ago. The study was supported by International Science Foundation, Smithsonian Institution, Washington D. C., and by Linnean Society of London. It is not easy to reconstruct how life developed on the Earth - too little stuff had... view more... (2000-12-01)
In the war between the sexes, the one with the closest fungal relationship wins
The war between the sexes has been fought on many fronts throughout time-from humans to birds to insects, the animal kingdom is replete with species involved in their own skirmishes. view more (2009-11-11)
Media Invitation - World record! -The Titan Arum expected to flower in Bonn on Friday or Saturday
The bloom with the world's largest inflorescence is about to flower at the Botanical Gardens of the University of Bonn. The Titan Arum (Amorphophallus titanum) has already reached a height of 268 centimeters - 1 centimeter more than the specimen grown in 1932 in the Dutch town of Wageningen that held the world record up to now. Apart from its mere... view more... (2003-05-21)
Massive Duplication of Genes May Solve Darwin's "Abominable Mystery" about Flowering Plants
Researchers from the Floral Genome Project at Penn State University, with an international team of collaborators, have proposed an answer to Charles Darwin's "abominable mystery:" the inexplicably rapid evolution of flowering plants immediately after their first appearance some 140 million years ago. view more (2006-05-11)
