Researchers have identified a critical amino acid transporter, SlAAP6, that enhances tomato growth and salt tolerance by mediating the uptake and distribution of branched-chain amino acids (BCAAs). Overexpressing SlAAP6 elevated BCAA levels, boosted plant biomass, and improved stress resistance, while knockout mutants exhibited stunted growth and heightened salt sensitivity. The study revealed that SlAAP6 not only promotes amino acid accumulation but also mitigates reactive oxygen species (ROS) damage under salt stress. These findings offer promising strategies for genetically improving tomato crops by simultaneously enhancing nutritional quality, growth, and abiotic stress resilience through targeted manipulation of amino acid transport mechanisms.

Scientists have discovered that Mn3Si2Te6 changes from an insulator to an electrically conductive metal when exposed to a magnetic field. In Mn3Si2Te6, applying a magnetic field causes a weak metallic state with trapped electrical changes to form in the material. This study examined the processes that cause this behavior.

An international team of scientists has moved beyond just 鈥渟cratching the surface,鈥� to understand how microplastics move through and impact the global ocean. For the first time, scientists have mapped microplastic distribution from the surface to the deep sea at a global scale 鈥� revealing not only where plastics accumulate, but how they infiltrate critical ocean systems.
