Pathogenic variants of the mitochondrial copper chaperones SCO1 and SCO2 reshape their respective interactomes and disrupt cellular phospholipid metabolism

SCO1 and SCO2 are required for copper delivery to COX2, a copper-containing subunit of cytochrome c oxidase (COX), yet how mutations in these genes cause distinct, tissue-specific forms of human disease remains poorly understood. To gain further insight into the molecular underpinnings of this clinical heterogeneity, we used BioID to map the interactomes of four pathogenic SCO variants (SCO1…

Crown-of-thorns starfish can help reefs thrive

Crown-of-thorns starfish (COTS) are infamous in the marine world. Their toxin-loaded thorns give them a menacing appearance, and they have a reputation as destroyers of coral reefs. New research from the University of Sydney challenges the perception of COTS as purely destructive.

Delaying cherry blossom to reduce frost damage

Climate change is causing many fruit trees to flower earlier, increasing their exposure to damaging late spring frosts. A study led by the University of Göttingen shows that the plant growth regulator ethephon can delay flowering in Kordia, a sweet cherry variety, potentially protecting blossoms and developing fruitlets from frost.
