TMEM37 and Autoimmunity: That certain accessions with high SA exhibited increased resistance to Pst DC3000 or PR1 expression without a measurable biomass penalty (eg. Ven-1, Kas-2, PHW-13 in Figs 2C–2E and 3A and 3B), points to genotypic variation in the threshold at which SA leads to autoimmunity[28].
