“…This might have been due to the interaction between SDIR1 and SDIRIP1 quickly driving SDIRIP1 degradation via the 26S proteasome. Similarly, Ning et al (2011) described that the colocalization of the rice (Oryza sativa) RING finger E3 ligase OsDIS1 (DROUGHT-INDUCED SEVEN IN ABSENTIA PROTEIN1) with its substrate Os-Nek6 (NEVER-IN-MITOSIS/ ASPERGILLUS-RELATED KINASE6) was almost undetectable in vivo, but Os-DIS1 H71Y , losing E3 activity due to a point mutation in the RING motif, was well colocalized with Os-Nek6. SDIR1 H234Y , which destroyed the E3 activity of SDIR1 but remained in the same cellular localization as SDIR1, could still interact with SDIRIP1 in yeast two-hybrid assays.…”

The plant hormone abscisic acid (ABA) regulates many aspects of plant development and the stress response. The intracellular E3 ligase SDIR1 (SALT-AND DROUGHT-INDUCED REALLY INTERESTING NEW GENE FINGER1) plays a key role in ABA signaling, regulating ABA-related seed germination and the stress response. In this study, we found that SDIR1 is localized on the endoplasmic reticulum membrane in Arabidopsis thaliana. Using cell biology, molecular biology, and biochemistry approaches, we demonstrated that SDIR1 interacts with and ubiquitinates its substrate, SDIRIP1 (SDIR1-INTERACTING PROTEIN1), to modulate SDIRIP1 stability through the 26S proteasome pathway. SDIRIP1 acts genetically downstream of SDIR1 in ABA and salt stress signaling. In detail, SDIRIP1 selectively regulates the expression of the downstream basic region/leucine zipper motif transcription factor gene ABA-INSENSITIVE5, rather than ABA-RESPONSIVE ELEMENTS BINDING FACTOR3 (ABF3) or ABF4, to regulate ABA-mediated seed germination and the plant salt response. Overall, the SDIR1/SDIRIP1 complex plays a vital role in ABA signaling through the ubiquitination pathway.

“…Hot pepper (Capsicum annuum) RING MEMBRANE-ANCHOR 1 HOMOLOG1 functions as an E3 ligase, ubiquitinating the plasma membrane aquaporin PIP2;1 under water-deficient conditions ). The C3HC4 RING finger E3 ligase OsDIS1, which is predominantly localized in the nucleus, plays a negative role in drought stress tolerance through the transcriptional regulation of diverse stress-related genes and possibly through the posttranslational regulation of OsNek6 in rice (Ning et al, 2011). The rice RING finger E3 ligase HEAT AND COLD INDUCED1 drives the nuclear export of multiple substrate proteins, and its heterogenous overexpression enhances acquired thermotolerance (Lim et al, 2013a).…”

The RING Finger Ubiquitin E3 Ligase OsHTAS Enhances Heat Tolerance by Promoting H2O2-Induced Stomatal Closure in Rice

Heat stress often results in the generation of reactive oxygen species, such as hydrogen peroxide, which plays a vital role as a secondary messenger in the process of abscisic acid (ABA)-mediated stomatal closure. Here, we characterized the rice (Oryza sativa) HEAT TOLERANCE AT SEEDLING STAGE (OsHTAS) gene, which plays a positive role in heat tolerance at the seedling stage. OsHTAS encodes a ubiquitin ligase localized to the nucleus and cytoplasm. OsHTAS expression was detected in all tissues surveyed and peaked in leaf blade, in which the expression was concentrated in mesophyll cells. OsHTAS was responsive to multiple stresses and was strongly induced by exogenous ABA. In yeast two-hybrid assays, OsHTAS interacted with components of the ubiquitin/26S proteasome system and an isoform of rice ascorbate peroxidase. OsHTAS modulated hydrogen peroxide accumulation in shoots, altered the stomatal aperture status of rice leaves, and promoted ABA biosynthesis. The results suggested that the RING finger ubiquitin E3 ligase OsHTAS functions in leaf blade to enhance heat tolerance through modulation of hydrogen peroxide-induced stomatal closure and is involved in both ABA-dependent and DROUGHT AND SALT TOLERANCE-mediated pathways.

“…The nek6 mutation enhanced stress tolerance whereas NEK6 overexpression reduced stress tolerance in the study by Lee et al (2010). In that by Zhang et al (2011), the nek6-1 mutation led to reduced stress tolerance whereas NEK6 overexpression promoted stress tolerance. Although the reason for this discrepancy remains unknown, it could be due to differences in the growth conditions, stress treatments, and the nek6 alleles used in two studies.…”

Microtubules are cytoskeletal polymers composed of α-and β-tubulin heterodimers. Microtubules are polarized with a fast growing plus end and a slow growing minus end, and exhibit dynamic behaviors such as rapid growth and shrinkage both in vivo and in vitro (Mitchison and Kirschner 1984; Horio and Hotani 1986; Sammak and Borisy 1988; Shaw et al. 2003;Nakamura et al. 2004). Cortical microtubules are specifically found in plant cells during interphase and are localized close to the cell cortex (Ledbetter and Porter 1963). Cortical microtubules align perpendicularly to the growth direction and regulate anisotropic growth and morphogenesis of rapidly expanding cells (Green 1962; Shibaoka 1994;Wasteneys 2002; Fig. 1). Findings from genetic studies of Arabidopsis thaliana mutants strongly support the essential roles of cortical microtubule arrays on directional cell growth (Whittington et al. 2001; Thitamadee et al. 2002; Abe et al. 2004; Ishida et al. 2007a; Ishida et al. 2007b; Sedbrook and Kaloriti 2008;Wasteneys and Ambrose 2009). In addition, microtubules regulate cell division and chromosome segregation. In the mitotic phase, microtubules form a series of arrays; a preprophase band that determines the future cell division plane, mitotic spindle that segregate chromosomes, and a phragmoplast that constructs the new cell plate ( 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 suggesting that cortical microtubules could also regulate directional cell growth independently of cellulose microfibrils (Sugimoto et al. 2003). Fujita et al. (2011) have shown that cortical microtubule abundance affects cellulose crystallinity to promote directional cell growth.Microtubules might regulate the mobility and stability of cellulose synthase complexes to affect physical properties of cellulose microfibrils. Because it is beyond the scope of this review, Interested readers could consult the recent literature and references therein (Bringmann et al. 2012; Fujita et al. 2012; Lei et al. 2014). In this review, we will summarize recent findings on microtubule regulation with focus on phosphorylation-dependent regulatory mechanisms. Microtubule regulationMicrotubule-associated proteins (MAPs) play pivotal roles in the regulation of microtubule dynamics (Hamada 2014). MAPs affect microtubule assembly and bundling and regulate their geometry and organization. Because the function and regulation of MAPs have been well described in detail, we show here a few examples from a cellular and developmen...
