Abstract

Nuclear pores mediate all transport in and out of the nucleus. While nuclear pore complexes (NPCs) have been intensively studied in yeast and animals, they are not well characterized in plants. Nevertheless, forward and reverse genetic screens have identified plant nucleoporins with functions in various plant processes, including plant-microbe interactions. This indicates that signalling between cytoplasm and nucleus is a key event in the corresponding pathways. Loss of function mutants of Lotus japonicus NUCLEOPORIN85 (NUP85), NUP133 and NENA are impaired in arbuscular mycorrhiza and root nodule symbiosis and unable to induce symbiotic calcium oscillations in the nucleus. Arabidopsis thaliana NUP96 and NUP88 are required in both pathogen-associated molecular pattern (PAMP)-triggered and disease-resistance (R) gene-mediated defence signalling. In comparison to the yeast and animal systems, this review discusses possible specific and general functions and targets of plant nucleoporins with a focus on the role of the NPC in plant-microbe interactions.
