AbstractThe RNA degradosome, a multi-protein complex regulating mRNA in bacteria, assembles on the RNase E C-terminal domain (CTD) in Pseudomonadota (Proteobacteria) via short linear motifs (SLiMs). The composition of the Pseudomonas aeruginosa RNA degradosome is largely unknown, and its RNase E CTD shows limited similarity to those in models like Escherichia coli or Caulobacter crescentus. Our study characterizes the function of conserved SLiMs in P.

AbstractTransitions between dry and wet hydrologic states are the defining characteristic of non-perennial rivers and streams, which constitute the majority of the global river network. Although past work has focused on stream drying characteristics, there has been less focus on how hydrology, ecology and biogeochemistry respond and interact during stream wetting.

AbstractSurface water reservoirs are increasingly being relied upon to meet rising demands in the context of growing population and changing climate. However, the amount of water available in reservoirs (and the corresponding trends) have not been well quantified at the global scale. Here we use satellite observations to estimate the storage variations of 7245 global reservoirs from 1999 to 2018.
