Gene blocking lettuce germination also regulates flowering time

Like most annuals, lettuce plants live out their lives in quiet, three-act dramas that follow the seasons. Seed dormancy gives way to germination; the young plant emerges and grows; and finally in the climax of flowering, ...

Research advances on transplant ward pathogen

The fungus Cryptococcus causes meningitis, a brain disease that kills about 1 million people each year—mainly those with impaired immune systems due to AIDS, cancer treatment or an organ transplant. It's difficult to treat ...

How seeds recognise the seasons

Scientists at the University of York have played a key role in new research into the way 'mother' plants use their memory of the seasons to teach their seeds the most advantageous time to germinate.

Plants 'talk' to plants to help them grow

Having a neighborly chat improves seed germination, finds research in BioMed Central's open access journal BMC Ecology. Even when other known means of communication, such as contact, chemical and light-mediated signals, are ...

Steroids control gas exchange in plants

Plants leaves are sealed with a gas-tight wax layer to prevent water loss. Plants breathe through microscopic pores called stomata (Greek for mouths) on the surfaces of leaves. Over 40% of the carbon dioxide, CO2, in the ...
