8.A.138. The Constitutive Expresser of Pathogenesis-related 5 (CPR5) Family

Arabidopsis CONSTITUTIVE EXPRESSER of PATHOGENESIS-RELATED 5 (CPR5) has 564 aas and 5 C-terminal TMSs in a 1 + 4 TMS arrangement. It plays a role in gating as part of the nuclear pore complex (NPC), and mutations in CPR5 cause multiple defects, including aberrant trichomes, reduced ploidy levels, reduced growth and enhanced resistance to bacterial and fungal pathogens (Faisal et al. 2020). It regulates negatively the senescence and chlorotic lesions induced by biotic (e.g. pathogens) and abiotic (e.g. sugars, darkness) agents, probably by controlling programmed cell death (PDC) (Yoshida et al. 2002). It is a negative regulator of plant programmed cell death (PCD) and effector-triggered immunity (ETI) (Wang et al. 2014). It is a nucleoporin that when mutant, activates autoimmune responses that partially mimic effector-triggered immunity (ETI) (Faisal et al. 2020). It regulates negatively the senescence and chlorotic lesions induced by biotic (e.g. pathogens) and abiotic (e.g. sugars, darkness) agents, probably by controlling programmed cell death (PDC) (Yoshida et al. 2002). It is a negative regulator of plant programmed cell death (PCD) and effector-triggered immunity (ETI) (Wang et al. 2014). It is a nucleoporin that when mutant, activates autoimmune responses that partially mimic effector-triggered immunity (ETI) (<Yoshida et al. 2002). It is a negative regulator of plant programmed cell death (PCD) and effector-triggered immunity (ETI) (Wang et al. 2014). It is a nucleoporin that when mutant, activates autoimmune responses that partially mimic effector-triggered immunity (ETI) (Xu et al. 2021).
