Abstract: Nuclear pore complex (NPC) is one of the large protein complex in nuclear envelope, and is involved in lots of growth and developmental processes through gating nucleocytoplasmic trafficking of RNA and proteins in various organisms. Currently, only several components function of NPC have been  analyzed in plants. Though identifying the mutants of all members in NUP107-160 subcomplex and analyzing their phenotypes, this paper found that mutants of nup160, nup96, nup85, nup107, and seh1 had longer circadian periods of leaf movement and shorter primary roots. But, only three mutants, nup160, nup96, and nup107,  significantly displayed early flowering. The results indicated that NUP107-160 subcomplex might be a novel player for the regulation of circadian clock, root elongation, and flowering time in Arabidopsis.
