In our previous study, no SMAP1-dependent difference was observed in the RUB modification status of CUL1, except in a special case: the percentage of RUB-modified CUL1 increased slightly in the flower extracts of transgenic plants ectopically expressing in the background.6 In this work, to further investigate the relationship between SMAP1 and RUB modification, we examined the effects of MLN4924, an inhibitor of RUB/NEDD8-activating E1 enzyme,9 on growth of WT and Arabidopsis seedlings. its interaction with components associated with the RUB modification system.

In our earlier study, no SMAP1-dependent difference was observed in the RUB changes status of CUL1, except in a special case: the percentage of RUB-modified CUL1 improved slightly in the blossom components of transgenic vegetation ectopically expressing in the background.6 In this work, to further investigate the relationship between SMAP1 and RUB changes, we examined the effects of MLN4924, an inhibitor of RUB/NEDD8-activating E1 enzyme,9 on growth of WT and Arabidopsis seedlings. MLN4924 is definitely structurally related to adenosine monophosphate and forms a NEDD8-MLN4924 adduct that resembles the 1st intermediate in the reaction, NEDD8-adenylate, but cannot be used in subsequent intra-enzyme reactions.10 In vegetation, MLN4924 is also reported to be an efficient inhibitor of RUB/NEDD8 conjugation.11 To test the effect of this inhibitor, we plated seeds on Germination Medium (GM; half-strength Murashige and Skoog salts, 0.5 gLC1 MES (pH 5.8), 1% [w/v] sucrose, 1 B5 vitamins and 0.8% [w/v] Bacto agar) with or without MLN4924 (from Active Biochem, Wanchai, Hong Kong, and dissolved in dimethyl sulfoxide) in rectangular plates. To synchronize germination, the plates were put in the dark for 2 d at 4 C, then transferred to a growth space at 24 C. Light-grown seedlings were cultivated vertically under 20C30 mol mC2 secC1 continuous light. For dark-grown seedlings, the plates were exposed to light for 4 h to induce germination and then wrapped in aluminium foil and kept vertically inside a cardboard package. To examine the gravitropic response of the origins, the plants were photographed with a digital camera and analyzed using NIH ImageJ (National Institution of Health, USA). Number?1 shows the effects of MLN4924 on 5-d-old light-grown seedlings. We observed agravitropic root responses and a significant reduction of root growth in MLN4924-treated WT (Fig.?1A), as previously reported.11 By contrast, the seedlings showed a more severe effect of MLN4924, especially within the direction of the root growth (Fig.?1A). To evaluate the effect of MLN4924 more exactly, 4-d-old light-grown seedlings were transferred onto GM comprising 5 M MLN4924 and were placed at 135 to the vertical. The positions of root tips were designated before and after the 2-d incubation and the direction of root growth was analyzed. The root growth toward the direction of gravity in WT was only slightly disturbed by MLN4924, but the roots of most of the seedlings did not grow in the direction of gravity (Fig.?1B), clearly suggesting that this seedlings are more sensitive to MLN4924 than the WT seedlings.

We observed agravitropic root responses and a significant reduction of root growth in MLN4924-treated WT (Fig.?1A), as previously reported.11 By contrast, the seedlings showed a more severe effect of MLN4924, especially around the direction of the root growth (Fig.?1A).
