Research Highlights

CRISPR-Associated Complex for Antiviral Defense

Macchess Icon

Within the past decade it was discovered that many cells have an adaptive immune system to fight off foreign RNA or DNA which may have been inserted by a viral, plasmid or transposon attack.

Key to pathogenic slime uncovered

In the biofilm regulation pathway of Pseudomonas fluorescens and similar bacteria, high phosphate levels lead to the creation of messenger molecule cyclic-di-guanosin monophosphate (CDGMP).
