Experiments illuminate key component of plants' immune systems

Plants, like humans and animals, have over millions of years evolved complex immune systems that fend off invading pathogens. But unlike many animals, plants lack adaptive immunity conferred by antibodies. This means each ...

Discovery could pave the way for disease-resistant rice crops

Researchers have uncovered an unusual protein activity in rice that can be exploited to give crops an edge in the evolutionary arms race against rice blast disease, a major threat to rice production around the world.

Upcycling of proteins protects DNA from parasites

Of the three billion base pairs in the human genome, less than two percent contain the information encoding the ~20,000 proteins. That is, because at least half of our genetic material originated from selfish genetic elements ...

Detox pathway extends lifespan of the worm C. elegans

A mutant worm with a change in one mitochondrial gene produces more reactive oxygen species (ROS), which can be harmful to cells by causing oxidative stress. However, this mutant worm is able to live twice as long as the ...

Programmed cell death

Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program. In contrast to necrosis, which is a form of cell-death that results from acute tissue injury and provokes an inflammatory response, PCD is carried out in a regulated process which generally confers advantage during an organism's life-cycle. PCD serves fundamental functions during both plant and metazoa (multicellular animals) tissue development.
