Article Synopsis
  • Life evolved in a reducing environment but faced challenges from reactive oxygen species (ROS) during the great oxidation event (GOE), leading to the development of copper-zinc superoxide dismutases (CuZnSODs) in some plants.
  • The chemical inhibitor lung cancer screen 1 (LCS-1) was used to study the effects of CuZnSOD inhibition on plant growth, transcription, and metabolism across different species, including bryophytes and vascular plants.
  • The results showed that LCS-1 caused oxidative stress and a core physiological response related to glutathione balance in all species, but varying metabolic responses were observed based on the number and types of CuZnSOD isoforms present in each plant.

Manufacturing and formulation of stable, high purity, and high dose bacteriophage drug products (DPs) suitable for clinical usage would benefit from improved process monitoring and control of critical process parameters that affect product quality attributes. Chemistry, Manufacturing, and Controls (CMC) for both upstream (USP) and downstream processes (DSP) need mapping of critical process parameters (CPP) and linking these to critical quality attributes (CQA) to ensure quality and consistency of phage drug substance (DS) and DPs development. Single-use technologies are increasingly becoming the go-to manufacturing option with benefits both for phage bioprocess development at the engineering run research stage and for final manufacture of the phage DS.

The prevalence of hypersensitivities towards wheat has increased in the last decades. Apart from celiac disease these include allergic and other inflammatory reactions summarized under the term non-celiac wheat sensitivity. One suspected trigger is the family of amylase/trypsin-inhibitors (ATIs), non-gluten proteins that are prominent wheat allergens and that activate the toll-like receptor 4 on intestinal immune cells to promote intestinal and extra-intestinal inflammation.

Grain size is potentially yield determining in wheat, controlled by the ubiquitin pathway and negatively regulated by ubiquitin receptor DA1. We analyzed whether increased thousand grain weight in wheat mutant is translated into higher grain yield and whether additional carbon provided by elevated (e)CO can be better used by the , displaying higher grain sink strength and size. Yield-related, biomass, grain quality traits, and grain dimensions were analyzed by two-factorial mixed-model analysis, regarding genotype and eCO.
