A network of transcriptional repressors modulates auxin responses @article{PMID:33208947,Title={A network of transcriptional repressors modulates auxin responses},Author={Truskina, Jekaterina and Han, Jingyi and Chrysanthou, Elina and Galvan-Ampudia, Carlos S and Lainé, Stéphanie and Brunoud, Géraldine and Macé, Julien and Bellows, Simon and Legrand, Jonathan and Bågman, Anne-Maarit and Smit, Margot E and Smetana, Ondřej and Stigliani, Arnaud and Porco, Silvana and Bennett, Malcolm J and Mähönen, Ari Pekka and Parcy, François and Farcot, Etienne and Roudier, Francois and Brady, Siobhan M and Bishopp, Anthony and Vernoux, Teva},DOI={10.1038/s41586-020-2940-2},Number={7840},Volume={589},Month={January},Year={2021},Journal={Nature},ISSN={0028-0836},Pages={116—119},Abstract={The regulation of signalling capacity, combined with the spatiotemporal distribution of developmental signals themselves, is pivotal in setting developmental responses in both plants and animals&lt;sup&gt;1&lt;/sup&gt;. The hormone auxin is a key signal for plant growth and development that acts through the AUXIN RESPONSE FACTOR (ARF) transcription factors&lt;sup&gt;2-4&lt;/sup&gt;. A subset of these, the conserved class A ARFs&lt;sup&gt;5&lt;/sup&gt;, are transcriptional activators of auxin-responsive target genes that are essential for regulating auxin signalling throughout the plant lifecycle&lt;sup&gt;2,3&lt;/sup&gt;. Although class A ARFs have tissue-specific expression patterns, how their expression is regulated is unknown. Here we show, by investigating chromatin modifications and accessibility, that loci encoding these proteins are constitutively open for transcription. Through yeast one-hybrid screening, we identify the transcriptional regulators of the genes encoding class A ARFs from Arabidopsis thaliana and demonstrate that each gene is controlled by specific sets of transcriptional regulators. Transient transformation assays and expression analyses in mutants reveal that, in planta, the majority of these regulators repress the transcription of genes encoding class A ARFs. These observations support a scenario in which the default configuration of open chromatin enables a network of transcriptional repressors to regulate expression levels of class A ARF proteins and modulate auxin signalling output throughout development.},URL={https://doi.org/10.1038/s41586-020-2940-2}} .

The growth of a stable stationary structure: coordinating cell behavior and patterning at the shoot apical meristem @article{PMID:29073502,Title={The growth of a stable stationary structure: coordinating cell behavior and patterning at the shoot apical meristem},Author={Truskina, Jekaterina and Vernoux, Teva},DOI={10.1016/j.pbi.2017.09.011},Volume={41},Month={February},Year={2018},Journal={Current opinion in plant biology},ISSN={1369-5266},Pages={83—88},Abstract={Plants are characterized by their ability to produce new organs post-embryonically throughout their entire life cycle. In particular development of all above-ground organs relies almost entirely on the function of the shoot apical meristem (SAM). The SAM performs a dual role by maintaining a pool of undifferentiated cells and simultaneously driving cell differentiation to initiate organogenesis. Both processes require strict coordination between individual cells which leads to formation of reproducible morphological and molecular patterns within SAM. The patterns are formed and maintained in large part due to spatio-temporal variation in signaling of plant hormones auxin and cytokinin resulting in tissue-specific transcriptional regulation. Integration of these mechanisms into computational models further identifies the key regulatory interactions involved in SAM function.},URL={https://doi.org/10.1016/j.pbi.2017.09.011}} .

Root branching toward water involves posttranslational modification of transcription factor ARF7 @article{PMID:30573626,Title={Root branching toward water involves posttranslational modification of transcription factor ARF7},Author={Orosa-Puente, Beatriz and Leftley, Nicola and von Wangenheim, Daniel and Banda, Jason and Srivastava, Anjil K and Hill, Kristine and Truskina, Jekaterina and Bhosale, Rahul and Morris, Emily and Srivastava, Moumita and Kümpers, Britta and Goh, Tatsuaki and Fukaki, Hidehiro and Vermeer, Joop E M and Vernoux, Teva and Dinneny, José R and French, Andrew P and Bishopp, Anthony and Sadanandom, Ari and Bennett, Malcolm J},DOI={10.1126/science.aau3956},Number={6421},Volume={362},Month={December},Year={2018},Journal={Science (New York, N.Y.)},ISSN={0036-8075},Pages={1407—1410},Abstract={Plants adapt to heterogeneous soil conditions by altering their root architecture. For example, roots branch when in contact with water by using the hydropatterning response. We report that hydropatterning is dependent on auxin response factor ARF7. This transcription factor induces asymmetric expression of its target gene &lt;i&gt;LBD16&lt;/i&gt; in lateral root founder cells. This differential expression pattern is regulated by posttranslational modification of ARF7 with the small ubiquitin-like modifier (SUMO) protein. SUMOylation negatively regulates ARF7 DNA binding activity. ARF7 SUMOylation is required to recruit the Aux/IAA (indole-3-acetic acid) repressor protein IAA3. Blocking ARF7 SUMOylation disrupts IAA3 recruitment and hydropatterning. We conclude that SUMO-dependent regulation of auxin response controls root branching pattern in response to water availability.},URL={https://doi.org/10.1126/science.aau3956}} .

Stabilization of cytokinin levels enhances Arabidopsis resistance against Verticillium longisporum @article{PMID:23594348,Title={Stabilization of cytokinin levels enhances Arabidopsis resistance against Verticillium longisporum},Author={Reusche, Michael and Klásková, Jana and Thole, Karin and Truskina, Jekaterina and Novák, Ondřej and Janz, Dennis and Strnad, Miroslav and Spíchal, Lukáš and Lipka, Volker and Teichmann, Thomas},DOI={10.1094/mpmi-12-12-0287-r},Number={8},Volume={26},Month={August},Year={2013},Journal={Molecular plant-microbe interactions : MPMI},ISSN={0894-0282},Pages={850—860},Abstract={Verticillium longisporum is a vascular pathogen that infects the Brassicaceae host plants Arabidopsis thaliana and Brassica napus. The soilborne fungus enters the plant via the roots and colonizes the xylem of roots, stems, and leaves. During late stages of infections, Verticillium spp. spread into senescing tissue and switch from biotrophic to a necrotrophic life style. Typical symptoms of V. longisporum-induced disease are stunted growth and leaf chlorosis. Expression analyses of the senescence marker genes SENESCENCE-ASSOCIATED GENE12, SENESCENCE-ASSOCIATED GENE13, and WRKY53 revealed that the observed chlorosis is a consequence of premature senescence triggered by Verticillium infection. Our analyses show that, concomitant with the development of chlorosis, levels of trans-zeatin decrease in infected plants. Potentially, induction of cytokinin oxidase/dehydrogenase expression by Verticillium infection contributes to the observed decreases in cytokinin levels. Stabilization of Arabidopsis cytokinin levels by both pharmacological and genetic approaches inhibits Verticillium proliferation and coincides with reduced disease symptom development. In summary, our results indicate that V. longisporum triggers premature plant senescence for efficient host plant colonization.},URL={https://doi.org/10.1094/MPMI-12-12-0287-R}} .

Verticillium infection triggers VASCULAR-RELATED NAC DOMAIN7-dependent de novo xylem formation and enhances drought tolerance in Arabidopsis @article{PMID:23023171,Title={Verticillium infection triggers VASCULAR-RELATED NAC DOMAIN7-dependent de novo xylem formation and enhances drought tolerance in Arabidopsis},Author={Reusche, Michael and Thole, Karin and Janz, Dennis and Truskina, Jekaterina and Rindfleisch, Sören and Drübert, Christine and Polle, Andrea and Lipka, Volker and Teichmann, Thomas},DOI={10.1105/tpc.112.103374},Number={9},Volume={24},Month={September},Year={2012},Journal={The Plant cell},ISSN={1040-4651},Pages={3823—3837},Abstract={The soilborne fungal plant pathogen Verticillium longisporum invades the roots of its Brassicaceae hosts and proliferates in the plant vascular system. Typical aboveground symptoms of Verticillium infection on Brassica napus and Arabidopsis thaliana are stunted growth, vein clearing, and leaf chloroses. Here, we provide evidence that vein clearing is caused by pathogen-induced transdifferentiation of chloroplast-containing bundle sheath cells to functional xylem elements. In addition, our findings suggest that reinitiation of cambial activity and transdifferentiation of xylem parenchyma cells results in xylem hyperplasia within the vasculature of Arabidopsis leaves, hypocotyls, and roots. The observed de novo xylem formation correlates with Verticillium-induced expression of the VASCULAR-RELATED NAC DOMAIN (VND) transcription factor gene VND7. Transgenic Arabidopsis plants expressing the chimeric repressor VND7-SRDX under control of a Verticillium infection-responsive promoter exhibit reduced de novo xylem formation. Interestingly, infected Arabidopsis wild-type plants show higher drought stress tolerance compared with noninfected plants, whereas this effect is attenuated by suppression of VND7 activity. Together, our results suggest that V. longisporum triggers a tissue-specific developmental plant program that compensates for compromised water transport and enhances the water storage capacity of infected Brassicaceae host plants. In conclusion, we provide evidence that this natural plant-fungus pathosystem has conditionally mutualistic features.},URL={https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/23023171/?tool=EBI}} .
