Nucleoporins
Simultaneously with NEB, many nucleoporins redistribute
in the forming spindle close to MTs in endoplasmic reticulum-
like nuclear envelope remnants. Several plant nucleoporins
and nucleoporin complexes appear to be
homologous to those found in yeast and animals models
(Meier and Brkljacic, 2009; Tamura and Hara-Nishimura,
2013). Nup133 and Nup85 of Lotus japonicus play a role in
calcium signal transduction linked to fungal and rhizobial
symbiosis (Saito et al., 2007), showing that nuclear pore
complex proteins may play multiple roles. However, the
function of plant nucleoporins during mitosis remains to
be explored, and is currently only based on knowledge
obtained in animal systems (Xu and Meier, 2008). It would
be interesting to know whether nuclear pore-associated
proteins are re-located at kinetochores during mitosis as in
animal cells and play similar roles.
