Arabidopsis thaliana serpins AtSRP4 and AtSRP5 negatively regulate stress-induced cell death and effector-triggered immunity induced by bacterial effector AvrRpt2.

Abstract excerpt

Protease inhibitors and their cognate proteases regulate growth, development and defense. Serine protease inhibitors (serpins) constitute a large family of genes in most metazoans and plants. Drosophila NECROTIC (NEC) gene and its homologues in the mammalian system are well-characterized serpins, which play a role in regulating proteases that participate in cell death pathways. Although the Arabidopsis genome...
