Excess forest mortality is consistently linked to drought across Europe
Nature Communications, Published online: 03 December 2020; doi:10.1038/s41467-020-19924-1 Droughts pose an increasingly important threat to forests. Here the authors analyse a high-resolution Landsat-based dataset of forest canopy mortality in Europe over 1987–2016 to show that drought is already a major driver of tree mortality.

Docking of acetyl-CoA carboxylase to the plastid envelope membrane attenuates fatty acid production in plants
Nature Communications, Published online: 03 December 2020; doi:10.1038/s41467-020-20014-5 In plants, light-dependent activation fatty acid synthesis (FAS) is mediated in part by acetyl-CoA carboxylase (ACCase). Here the authors identify a family of genes encoding carboxyltransferase interactors that attenuate FAS in the light by docking acetyl-CoA carboxylase to the plastid envelope.

TGFβ promotes widespread enhancer chromatin opening and operates on genomic regulatory domains
Nature Communications, Published online: 03 December 2020; doi:10.1038/s41467-020-19877-5 The TGFβ signaling pathway has been shown to regulate transcription by regulating enhancer activity. Here, the authors perform a comprehensive analysis of enhancers in normal mammary epithelial gland cells to elucidate how TGFβ-dependent enhancers control gene transcription in these cells.
