This paper shows cyanobacteria can use guanidine as a nitrogen source, regulated by NtcA and a riboswitch, enabling precise gene control for synthetic biology.

The paper identifies 45 new zymocin-like toxin genes in budding yeasts, showing their diversity and suggesting VLEs have been parasitic for over 300 million years.

The paper designs synthetic neomycin-responsive riboswitches and shows that their function depends on sequence context, introducing in silico methods to improve design.
