The mechanisms by which plants switch between growth and stress survival remain somewhat enigmatic. Following on from previous studies, Gong et al. revealed that the conserved N-terminal acetyltransferase B (NatB) helps regulate this balance. Arabidopsis mutants lacking the catalytic subunit of NatB, NAA20, show disrupted N-terminal acetylation of NatB substrates, and these plants exhibited slower […]
Enhancing photosynthetic CO₂ fixation to increase crop yields is a major focus in plant biotechnology. Notably, several algal species form pyrenoids, phase-separated organelles that boost the activity of the CO₂-fixing enzyme Rubisco by supplying it with concentrated CO₂, thereby making carboxylation more efficient. Among land plants, hornworts are the only lineage with species known to […]
Across multicellular eukaryotes, ARGONAUTE (AGO) proteins are the core of RNA silencing, steering development, defense, and stress responses by biding small RNA guides to seek out genes for repression. In plants and animals, these functions are distributed across multiple AGO homologs that support a wide range of regulatory processes. A notable exception to this pattern […]
