font-family: calibri, sans-serif; color: black;">Organellar retrograde signals are vital in determining stress reactions in plants. We have identified Protein Phosphatase 2A (PP2A) as a cytosolic factor that controls organelle-induced stress reactions and pathogenesis responses in Arabidopsis thaliana. PP2A regulatory subunit B’γ (PP2A-B’γ) is required to maintain growth and prevent premature senescence under favorable conditions. On a molecular level, PP2A-B’γ controls multiple phosphoproteins that are elicited by mitochondrial dysfunction and critical in determining metabolic activities and detoxification capacity in plant cells. Under stress, the promoter of PP2A-B’γ becomes transiently inactivated by mitochondrial dysfunction signals. Hence, PP2A-B’γ does not prevent stress responses upon environmental challenges, but is an important regulator of stress recovery. Phosphoproteomic analysis suggests networks related to plant immunity, vesicle transport and RNA metabolism as regulation targets for PP2A-B’γ. PP2A-B’γ as a post-transcriptional regulator of mitochondrial dysfunction responses and stress recovery will be presented.<span style="mso-spacerun: yes;"> </span></span><span lang="EN" style="font-size: 10pt; font-family: calibri, sans-serif;"></span></p> <br><p class="MsoNormal" style="text-align: justify; margin: 0px;"><br></p><br><h3><br></h3><h3>Jozef Schell seminar room<br>Technologiepark 71 - 9052 </h3><br><br><br><br>Invited by Prof Dirk Inzé and Prof Frank Van Breusegem<br><br>If you do not wish to receive this information anymore, please unsubscribe from future mailings at <a href="https://maillist.psb.ugent.be/mailman/listinfo/seminars" rel="nofollow noopener noreferrer nofollow noopener noreferrer nofollow noopener noreferrer" target="_blank">https://maillist.psb.ugent.be/mailman/listinfo/seminars</a><br><p style="color: rgb(0, 32, 96); font-family: sans-serif; font-size: 13.3333px; font-style: normal; font-weight: 400; letter-spacing: normal; text-align: center; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; background-color: rgb(255, 253, 251); margin: 0px;"><span style="color: rgb(65, 183, 185);"><b></b></span><br></p><p style="color: rgb(0, 32, 96); font-family: sans-serif; font-size: 13.3333px; font-style: normal; font-weight: 400; letter-spacing: normal; text-align: center; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; background-color: rgb(255, 253, 251); margin: 0px;"><span style="color: rgb(65, 183, 185);"><b></b></span><br></p><p style="color: rgb(0, 32, 96); font-family: sans-serif; font-size: 13.3333px; font-style: normal; font-weight: 400; letter-spacing: normal; text-align: center; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; background-color: rgb(255, 253, 251); margin: 0px;"><span style="color: rgb(65, 183, 185);"><b>Genome editing, cutting-edge technology for a sustainable agriculture</b></span></p><br><img alt="banner mail" width="498" height="81" data-mce-src="https://psbzim02.psb.ugent.be/home/signature@psb.ugent.be/Briefcase/PUBLIC/footer.png" src="https://psbzim02.psb.ugent.be/home/signature@psb.ugent.be/Briefcase/PUBLIC/footer.png" saveddisplaymode="" style=""><br>VIB-UGent Center for Plant Systems Biology</center><center>Ghent University<br>Technologiepark-Zwijnaarde 71<br>9052 Ghent-Belgium<br>Phone: +32(0)9 331 38 00<br><a href="http://www.psb.vib-ugent.be" rel="nofollow noopener noreferrer nofollow noopener noreferrer nofollow noopener noreferrer" target="_blank">https://www.psb.ugent.be/</a></center></div></div></div></div></div></div></div></div><br></div><style><!--
