2Dual and opposing roles of EIN3 reveal a generation conflict during seed growth显示文摘Seed size critically affects grain yield of crops and hence represents a key breeding target.The develop-ment of embryo-nourishing endosperm is a key driver of seed expansion.We here report unexpected dual roles of the transcription factor EIN3 in regulating seed size.These EIN3 functions have remained largely undiscovered because they oppose each other.Capitalizing on the analysis of multiple ethylene biosynthesis mutants,we demonstrate that EIN3 represses endosperm and seed development in a pathway regulated by ethylene.We,in addition,provide evidence that EIN3-mediated synergid nucleus disintegration promotes endosperm expansion.Interestingly,synergid nucleus disintegration is not affected in various ethylene biosynthesis mutants,suggesting that this promoting function of EIN3 is inde-pendent of ethylene.Whereas the growth-inhibitory ethylene-dependent EIN3 action appears to be encoded by sporophytic tissue,the growth-promoting role of EIN3 is induced by fertilization,revealing a generation conflict that converges toward the key signaling component EIN3.Juliane Heydlauff Isil Erbasol Serbes Dieu Vo Yanbo Mao Sonja Gieseking Thomas Nakel Theresa Harten Ronny Völz Anja Hoffmann Rita GroΒ-Hardt 2022Molecular Plant2022,15,2:1

6CD2 deficiency partially prevents small bowel inflammation and improves parasite control in murine Toxoplasma gondii infection显示文摘AIM: To investigate whether bowel inflammation and/or parasite control is altered in the absence of the T cell adhesion molecule CD2. METHODS: Wildtype (WT) and CD2 deficient (CD2-/-) mice were infected with 100 cysts of Toxoplasma gondii (T. gondii) (ME49) by gavage. On d 7 after infection mice were killed. Necrosis and the number of parasites/cm il-eum were determined. Cytokine levels of stimulated cells as well as sera were evaluated. Secondly, survival of WT vs CD2-/-mice was analysed using Kaplan-Meier analysis. RESULTS: CD2-/-mice survived longer than WT mice (mean: 23.5 vs 7.1 d, P = 0.001). Further, CD2-/-mice showed less weight loss and less ileal inflammation than WT mice at d 7 post infection. In addition, the number of parasites in the ileum was signif icantly lower in CD2-/-mice than in WT mice (88 ± 12 vs 349 ± 58 cm, P < 0.01). This was paralleled by lower production of IFN-γ and IL-6 from TLA-stimulated mLN cells and increased IFN-γ pro-duction by splenocytes. CONCLUSION: CD2 defi cient mice are more resistant to T. gondii infection than WT mice. In contrast to most current immunosuppressive or biological therapies CD2 deficiency reduces intestinal inflammation and at the same time helps to control infection.Nina N Pawlowski Daniela Struck Katja Grollich Anja A Kühl Martin Zeitz Oliver Liesenfeld Jrg C Hoffmann 2007World Journal of Gastroenterology2007,13,31:0
7Predicting the effectiveness of protected areas of Natura 2000 under climate change显示文摘Background:Protected areas(PAs)are aimed to hold the environmental conditions that facilitate species and ecosystems to persist.PAs can become climatically unsuitable and unable to sustain their current number of species under climate change.The Natura 2000(N2K)is the largest coordinated conservation tool assigned to maintain the long-term survival of Europe’s most significant species and habitats.In attempting to understand the effectiveness of PAs in the face of climate change scenarios,we tested two hypotheses:(1)PAs in the Alpine and the Boreal biogeographical regions will experience more newly emerged climate conditions(hotter and drier)compared to the climate representation of other biogeographical regions under future climate in Europe and(2)PAs in the Mediterranean and the Continental biogeographical regions will face more consistency in climate conditions due to less area of disappearing and novel climate in future.Methods:Current climate data(1960–1990)and projections for 2050 and 2070 of PAs of N2K were extracted from WorldClim global climate data.Principal components analysis(PCA)was performed to construct climate space for the PAs across the biogeographical regions based on 19 climatic variables assessed at 5-km resolution.ArcMap 10.1 was used to map the location of the novel and disappearing climates.Results:PAs in the Alpine region will experience more novel climate conditions in the future compared to other biogeographical regions.The future projections showed that 17.70%of the PAs in the Alpine region will experience novel climate by 2070.Considerable climate consistency was observed in the PAs in the Continental region compared to the other biogeographical regions.Our results showed that about 176 km2 of the selected PAs in the Continental region will face new emerging climate,while about 110 km2 will disappear under RCP 8.5 scenario.The prediction also revealed that in the Mediterranean region 08 PAs will experience novel climate and 786 km2 areas in these PAs will face disappearing climate by 2070.We found that fewer areas of PAs in the Boreal regions will experience disappearing climate in both the scenarios.Conclusions:The portion of novel climate conditions can be seen as a future opportunity to assign new reserves for the species.Our study highlights the importance of conservation planning to increase the connectivity between PAs,identifying novel conservation zones to maximize representation of habitats during the emerging climatic changes as well as designing strategies,management,and monitoring of the individual PAs.Mst.Umme Salma Nila Carl Beierkuhnlein Anja Jaeschke Samuel Hoffmann Md Lokman Hossain 2019Ecological Processes2019,8,1:0
