text: The levels of HSP90-family proteins, which play a role in propagating the retrograde signal emanating from plastid precursor proteins5, were not significantly different between the ppi2 and rpn8a ppi2 mutant, but we observed a significant induction of cytHSP90 (At5g56000) in the rpn8a single mutant (factor 3.9, p-value 0.04, T-test, two-sided, Supplementary Data 1).
