Description
Xingchuan Huang found a phosphatase that props up a plant immune receptor in a 2026 Arabidopsis study. Protein Phosphatase 5 is widespread in animals, yet its plant role was unknown before this work on the receptor SUMM2.
Plants lacking PP5 lost the self-attack symptoms caused when a kinase chain guarding SUMM2 breaks down. Lab binding tests showed SUMM2 touching both PP5 and the chaperone HSP90, and receptor levels fell without PP5 in reported checks. The authors argue PP5 helps the chaperone complex keep SUMM2 stocked for defence. The find adds a new part to the known guard chain for this key immune switch.
