Recent work suggests a more complex role for Ca2+ in BAK1‐related cell death, as NLRs that mediate bak1 bkk1 autoimmunity have been identified, including the NLR CONSTITUTIVE SHADE‐AVOIDANCE 1 (CSA1) (preprint: Schulze et al, 2021) and helper NLRs of the ACTIVATED DISEASE RESISTANCE 1 (ADR1)‐like family (Wu et al, 2020b). The gene discussed is BAK1; the disease is Autoimmunity.
