Global changes alter the timing of plant growth, scientists say

...through 2003. "Under today's conditions, grasses flower early in the growing season and wildflowers flower later, but when we increased the concentration of carbon dioxide to simulate future conditions, the ...

How did bilaterally symmetric flowers evolve from radially symmetric ones?

...versidad de Granada, Spain) explored how different flower shapes affected plant fitness in natural populatio... selection can play a key role in the evolution of flower bilateral symmetry," says Camacho. "Our data also suggest that it is possible to understand the evol...

Brown team finds crucial protein role in deadly prion spread

...ster of flowers that each carries a seed. When the flower dries up and the wind blows, the seeds disperse. P... way. Hsp104 acts like the wind, blowing apart the flower and spreading the seeds." Serio said that prions still multiply without fragmentation. However, s...

World's largest flower evolved from family of much tinier blooms

UBC researchers reveal dwarf aquatic plants' hidden ancestry

...zens of minute flowers clustered into each compact flower head. Native to Australia, New Zealand and India, they thrive in seasonal freshwater pools and swamps, and may blossom underwater at depths of up to one metre, or as the pools dry out. "For more than a century, scientists have been piecing tog...

Whiteflies and plant viruses can help each other to speed up biological invasion

...spread invasion has been assisted by the worldwide flower trade. The question remains how this pest can increase so rapidly and displace native biotypes of whitefly after it has been transported to new localities. The research compared development, survival, fecundity and population increase of the inva...

Scientists seek useful traits in wild cottons

...(bracts) at the base of each boll a few days after flower blooms open. Determining whether this trait is dominant, co-dominant or recessive and finding its DNA location could help breeders develop upland cottons that require less lint cleaning ?producing cleaner fiber with less ginning costs, Gannaw...

Research identifies protein that signals flowering in squash plants

...g night) in order to flower. These are plants that flower as the days grow shorter, such as in the fall in temperate regions. Long day (LD) plants will flower when nights are short (and days are long), and typically flower in late spring or early summer. SD c...
