How do rootstocks mediate scion salinity tolerance under salt stress?
Grafting in tomato has been investigated mainly in small-scale experiments, demonstrating morphological, physiological, and metabolic changes in the scion mediated by the rootstock. By grafting a scion onto different rootstocks, scion salt tolerance.....»»
The plan to release genetically engineered mosquitoes in California
In the mosquito breeding rooms of British biotech company Oxitec, scientists line up fresh eggs, each the size of a grain of salt. Using microscopic needles, the white-coated researchers inject each egg with a dab of a proprietary synthetic DNA......»»
Epigenetic treatments: New allies for chemotherapies?
Though chemotherapies are effective in some patients, tumour cells may acquire tolerance to these treatments. In other words, cells adapt to chemotherapy so they can survive. A new study delivers promising results on epigenetic mechanisms that regula.....»»
