We examined the relationship between salt stress tolerance and dynamic instability of microtubules, and revealed an important role for proteasome-dependent regulation of microtubule-associated protein SPIRAL1in the survival of plants challenged by high salinity.

Titanium dioxide nanoparticles disrupt cortical microtubular arrays and alter cell expansion growth. Disruption of microtubules is followed by 26S proteasome-dependent degradation of tubulin monomers and the ubiquitin/26S proteasome proteolysis pathway overload.

Smalle (2010) Uptake and distribution of ultra-small anatase titanium dioxide Alizarin red S nanoconjugates in Arabidopsis thaliana. Nano Letters, 10:2296-2302 (COVER)
The ultrasmall anatase titanium dioxide nanoconjugates traverse cell walls, enter into plant cells, and accumulate in specific subcellular locations. Optical and X-ray fluorescence microscopy coregistered the nanoconjugates in cell vacuoles and nuclei.
The Arabidopsis 26S proteasome mutants (e.g., rpt2a-3, rpn10-1 and rpn12a-1) are hypersensitive to translation inhibitors hygromycin B and cycloheximide, and tolerant to glutamine synthase inhibitor BASTA (PPT). The combination of hygromycin B, cycloheximide and BASTA growth-response assays can be used as a diagnostic tool to detect altered 26S proteasome function in plant mutants and transgenic lines.

Plants lacking non-ATPase regulatory subunit 1a (RPN1a) are viable and have increased cell sizes, decreased heat shock and salt stress tolerance, and increased oxidative stress tolerance.
A review.
Optimal proteasome function is required to maintain final shoot organ size in Arabidopsis. Loss of function of the subunit regulatory particle AAA ATPase (RPT2a) causes a weak defect in 26S proteasome activity and leads to an enlargement of leaves, stems, flowers, fruits, seeds, and embryos. These size increases are a result of increased cell expansion that compensates for a reduction in cell number.

An opinion.
Plant cells increase 20S proteasome-dependent proteolysis when 26S proteasome activity is impaired. One of the consequences of the 26S/20S activity shift is an increase in oxidative stress tolerance and decrease in tolerance to heat shock.
