Research reveals how mitochondria keep their reactive oxygen species production in check


Research reveals how mitochondria keep their reactive oxygen species production in check
Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell s activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the other units in the cells. But when produced too abundantly, they damage DNA and render some cellular components dysfunctional. Now, an international research team has revealed how mitochondria keep their reactive oxygen species production in check.
They published their results on June 30 in
Frontiers in Cell and Developmental Biology.
Excessive generation of reactive oxygen species in mitochondria damages mitochondria and reduces cell function, so the mechanism by which mitochondria maintain production of reactive oxygen species is crucial for cells. In this study, we found that mitochondria have a mechanism to spontaneously avoid th ....

Increasing Drought Tolerance - AG INFORMATION NETWORK OF THE WEST


Increasing Drought Tolerance
University of Nevada, Reno research addressing future population growth and food shortages
 
After several years of experimentation, scientists have engineered thale cress, or Arabidopsis thaliana, to behave like a succulent, improving water-use efficiency, salinity tolerance and reducing the effects of drought. The tissue succulence engineering method devised for this small flowering plant can be used in other plants to improve drought and salinity tolerance with the goal of moving this approach into food and bioenergy crops.
 
“Water-storing tissue is one of the most successful adaptations in plants that enables them to survive long periods of drought. This anatomical trait will become more important as global temperatures rise, increasing the magnitude and duration of drought events during the 21st century,” said University of Nevada, Reno Biochemistry and Molecular Biology Professor John Cushman, co-author of a new scienti ....
