Rice plants overexpressing BiP3 are compromised in PRR XA3-mediated immunity to Xoo.
NB-LRR Pi5-mediated resistance to M. oryzae is not affected by BiP3 overexpression.
BiP3 overexpression does not lead to a general ER stress response.
BiP3 is involved in the biogenesis of membrane-resident PRRs XA3 and XA21.
