Nucleoporin 50 proteins affect longevity and salinity stress tolerance in seeds

Nucleoporin 50 (Nup50) is an evolutionarily conserved protein that is a constituent of the nuclear pore complex (NPC). Arabidopsis has two Nup50 proteins, Nup50a and Nup50b, which are highly expressed in developing seeds. Comparative transcriptomics using immature seeds of wild type and nup50a nup50b mutant was performed.
