Further genetic analysis shows that RPP1-likeLerDM2h underlies two additional cases of A. thaliana autoimmunity, one with a mutated form of a cysteine metabolic enzyme (O-acetylserine(thiol)lyase A1) gene in old3-1 within Ler [65, 66], the other causing HI with allelic forms of a receptor-like kinase gene, SRF3, present in A. thaliana Kas-2 and Kond and other Central Asian accessions (Fig 8) [25, 27]. The gene discussed is RPLP1; the disease is Autoimmunity.
