In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback regulation of auxin on the polarized localization of PIN auxin transporters in individual cells has been proposed as a self-organizing mechanism for coordinated tissue polarization, but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport remain unknown. We used a microarray-based approach to find regulators of the auxin-induced PIN relocation in Arabidopsis thaliana root, and identified a subset of a family of phosphatidylinositol transfer proteins (PITPs), the PATELLINs (PATLs). Here, we show that PATLs are expressed in partially overlapping cell types in different tissues going through mitosis or initiating differentiation programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis embryos, primary roots, lateral root primordia and developing stomata. Higher order patl mutants display reduced PIN1 repolarization in response to auxin, shorter root apical meristem, and drastic defects in embryo and seedling development. This suggests that PATLs play a redundant and crucial role in polarity and patterning in Arabidopsis.}, language = {en} } @article{BollierSicardLeblondetal.2018, author = {Bollier, Norbert and Sicard, Adrien and Leblond, Julie and Latrasse, David and Gonzalez, Nathalie and Gevaudant, Frederic and Benhamed, Moussa and Raynaud, Cecile and Lenhard, Michael and Chevalier, Christian and Hernould, Michel and Delmas, Frederic}, title = {At-MINI ZINC FINGER2 and Sl-INHIBITOR OF MERISTEM ACTIVITY, a Conserved Missing Link in the Regulation of Floral Meristem Termination in Arabidopsis and Tomato}, series = {The plant cell}, volume = {30}, journal = {The plant cell}, number = {1}, publisher = {American Society of Plant Physiologists}, address = {Rockville}, issn = {1040-4651}, doi = {10.1105/tpc.17.00653}, pages = {83 -- 100}, year = {2018}, abstract = {In angiosperms, the gynoecium is the last structure to develop within the flower due to the determinate fate of floral meristem (FM) stem cells. The maintenance of stem cell activity before its arrest at the stage called FM termination affects the number of carpels that develop. The necessary inhibition at this stage of WUSCHEL (WUS), which is responsible for stem cell maintenance, involves a two-step mechanism. Direct repression mediated by the MADS domain transcription factor AGAMOUS (AG), followed by indirect repression requiring the C2H2 zinc-finger protein KNUCKLES (KNU), allow for the complete termination of floral stem cell activity. Here, we show that Arabidopsis thaliana MINI ZINC FINGER2 (AtMIF2) and its homolog in tomato (Solanum lycopersicum), INHIBITOR OF MERISTEM ACTIVITY (SlIMA), participate in the FM termination process by functioning as adaptor proteins. AtMIF2 and SlIMA recruit AtKNU and SlKNU, respectively, to form a transcriptional repressor complex together with TOPLESS and HISTONE DEACETYLASE19. AtMIF2 and SlIMA bind to the WUS and SIWUS loci in the respective plants, leading to their repression. These results provide important insights into the molecular mechanisms governing (FM) termination and highlight the essential role of AtMIF2/SlIMA during this developmental step, which determines carpel number and therefore fruit size.}, language = {en} } @article{GeigerKocyan2018, author = {Geiger, Daniel L. and Kocyan, Alexander}, title = {Studies on Oberonia 3.

The results show that the magnetosonic waves in both frequency bands occur around the postnoon (12-18 magnetic local time, MLT) sector outside the plasmapause when ER is comparable to or lower than EA, and those in lower-frequency bands (fcp < f ≤ 0.5 fLHR) occur around the postnoon sector inside the plasmapause when ER/EA > ~9. However, there is one discrepancy between occurrences of proton rings and magnetosonic waves in low-frequency bands around the prenoon sector (6-12 MLT) outside the plasmapause, which suggests either that the waves may have propagated during active time from the postnoon sector after being excited during quiet time, or they may have locally excited in the prenoon sector during active time.}, language = {en} } @article{LuReichetzederPrehnetal.2018, author = {Lu, Yong-Ping and Reichetzeder, Christoph and Prehn, Cornelia and von Websky, Karoline and Slowinski, Torsten and Chen, You-Peng and Yin, Liang-Hong and Kleuser, Burkhard and Yang, Xue-Song and Adamski, Jerzy and Hocher, Berthold}, title = {Fetal serum metabolites are independently associated with Gestational diabetes mellitus}, series = {Cellular physiology and biochemistry : international journal of experimental cellular physiology, biochemistry and pharmacology}, volume = {45}, journal = {Cellular physiology and biochemistry : international journal of experimental cellular physiology, biochemistry and pharmacology}, number = {2}, publisher = {Karger}, address = {Basel}, issn = {1015-8987}, doi = {10.1159/000487119}, pages = {625 -- 638}, year = {2018}, abstract = {Background/Aims: Gestational diabetes (GDM) might be associated with alterations in the metabolomic profile of affected mothers and their offspring. Until now, there is a paucity of studies that investigated both, the maternal and the fetal serum metabolome in the setting of GDM. Mounting evidence suggests that the fetus is not just passively affected by gestational disease but might play an active role in it. Metabolomic studies performed in maternal blood and fetal cord blood could help to better discern distinct fetal from maternal disease interactions. Methods: At the time of birth, serum samples from mothers and newborns (cord blood samples) were collected and screened for 163 metabolites utilizing tandem mass spectrometry. The cohort consisted of 412 mother/child pairs, including 31 cases of maternal GDM. Results: An initial non-adjusted analysis showed that eight metabolites in the maternal blood and 54 metabolites in the cord blood were associated with GDM. After Benjamini-Hochberg (BH) procedure and adjustment for confounding factors for GDM, fetal phosphatidylcholine acyl-alkyl C 32:1 and proline still showed an independent association with GDM. Conclusions: This study found metabolites in cord blood which were associated with GDM, even after adjustment for established risk factors of GDM. To the best of our knowledge, this is the first study demonstrating an independent association between fetal serum metabolites and maternal GDM.

The association with birth weight was stronger than classical confounding factors such as offspring sex (CI: - 258.81- -61.32; P = 0.002) and maternal smoking during pregnancy (CI: -298.74 - -29.51; P = 0.017). Conclusions: After correction for multiple testing and adjustment for potential confounders, LPC 16:1 showed a very strong and independent association with birth weight.

The existing theories on institutional reflexivity point to the potential contribution of benchmarking to public sector innovation and organizational learning. Based on survey findings, in-depth case studies, interviews and document analyses in these three countries, the paper addresses the major research question as to what extent and why benchmarking regimes vary across countries. It derives hypotheses about the impacts of benchmarking on institutional learning and innovation. Findings The outcomes suggest that the combination of three key features of benchmarking, namely - obligation, sanctions and benchmarking authority - in conjunction with country-specific administrative context conditions and local actor constellations - influences the impact of benchmarking as a reflexive institution. Originality/value It is shown in the paper that compulsory benchmarking on its own does not lead to reflexivity and learning, but that there is a need for autonomy and leeway for local actors to cope with benchmarking results. These findings are relevant because policy makers must decide upon the specific governance mix of benchmarking exercises taking their national and local contexts into account if they want them to promote institutional learning and innovation.}, language = {en} } @article{LenkeitSchwippertKnigge2018, author = {Lenkeit, Jenny and Schwippert, Knut and Knigge, Michel}, title = {Configurations of multiple disparities in reading performance}, series = {Assessment in education : principles, policy \& practice}, volume = {25}, journal = {Assessment in education : principles, policy \& practice}, number = {1}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {0969-594X}, doi = {10.1080/0969594X.2017.1309352}, pages = {52 -- 86}, year = {2018}, abstract = {Research provides evidence that gender, immigrant background and socio-economic characteristics present multiple disadvantaging characteristics that change their relative importance and configurations over time.

Mixed-effects models were fitted to the data. Outcomes \& Results: At the group level, both the Greek and Italian participants with AD performed worse than the controls. Both AD groups revealed selective patterns of morphosyntactic production (Greek: Agreement/Mood > Time Reference; Italian: Agreement > Time Reference > Mood).

Conclusions: The results indicate that the production of verb-related morphosyntactic categories can be impaired in mild-to-moderate AD. The different patterns observed in the two languages are partly attributable to the different way these languages encode Mood.

The bitter ironies of this disavowal become evident when Indigenous Australian quests for the remains of their ancestral dead lost in the limbo of German scientific collections are juxtaposed with white Australian (fictional) quests for the remains of Ludwig Leichhardt, lost in the Australian interior.}, language = {en} } @article{Selting2018, author = {Selting, Margret}, title = {For Charles Goodwin, Chuck}, series = {Co-operative engagements in intertwined semiosis: essays in honour of Charles Goodwin}, volume = {19}, journal = {Co-operative engagements in intertwined semiosis: essays in honour of Charles Goodwin}, publisher = {University of Tartu Press}, address = {Tartu}, isbn = {978-9949-77-688-7}, issn = {1406-4278}, pages = {361 -- 362}, year = {2018}, abstract = {This appreciation will not be a testimonial to Chuck's numerous publications and research achievements - I am sure that others will have a lot to say about those.

Assessing psychological work capacity demands is of specific importance when mental health problems at work endanger work ability. Exploring psychological work capacity demands is the basis for mental hazard analysis or rehabilitative action, e.g. in terms of work adjustment. OBJECTIVE: This is the first study investigating psychological work capacity demands in rehabilitation patients with and without mental disorders. METHODS: A structured interview on psychological work capacity demands (Mini-ICF-Work; Muschalla, 2015; Linden et al., 2015) was done with 166 rehabilitation patients of working age. All interviews were done by a state-licensed socio-medically trained psychotherapist. Inter-rater-reliability was assessed by determining agreement in independent co-rating in 65 interviews. For discriminant validity purposes, participants filled in the Short Questionnaire for Work Analysis (KFZA, Prumper et al., 1994). RESULTS: In different professional fields, different psychological work capacity demands were of importance. The Mini-ICF-Work capacity dimensions reflect different aspects than the KFZA. Patients with mental disorders were longer on sick leave and had worse work ability prognosis than patients without mental disorders, although both groups reported similar work capacity demands. CONCLUSIONS: Psychological work demands - which are highly relevant for work ability prognosis and work adjustment processes - can be explored and differentiated in terms of psychological capacity demands.}, language = {en} } @article{GanghofEppnerPoerschke2018, author = {Ganghof, Steffen and Eppner, Sebastian and P{\"o}rschke, Alexander}, title = {Semi-parliamentary government in perspective}, series = {Australian Journal of Political Science}, volume = {53}, journal = {Australian Journal of Political Science}, number = {2}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {1036-1146}, doi = {10.1080/10361146.2018.1451488}, pages = {264 -- 269}, year = {2018}, abstract = {The article responds to four commentaries on the concept of semi-parliamentary government and its application to Australian bicameralism.
