Flowering time, development and yield in oilseed rape (Brassica napus): Sequence diversity in regulatory genes

Flowering time (FTi) genes play a key role as regulators of complex gene expression networks, and the influence of these networks on other complex systems means that FTi gene expression triggers a cascade of regulatory effects with a broad global effect on plant development. Hence, allelic and expression differences in FTi genes can play a central role in phenotypic variation throughput the plant lifecycle. A prime example for this is found in Brassica napus, a phenotypically and genetically diverse species with enormous variation in vernalisation requirement and flowering traits. The species includes oilseed rape (canola), one of the most important oilseed crops worldwide. Previously we have identified QTL clusters related to plant development, seed yield and heterosis in winter oilseed rape that seem to be conserved in diverse genetic backgrounds. We suspect that these QTL are controlled by global regulatory genes that influence numerous traits at different developmental stages. Interestingly, many of the QTL clusters for yield and biomass heterosis appear to correspond to the positions of meta-QTL for FTi in spring-type and/or winter-type B. napus. Based on the hypothesis that diversity in FTi genes has a key influence on plant development and yield, the aim of this study is a detailed analysis of DNA sequence variation in regulatory FTi genes in B. napus, combined with an investigation of associations between FTi gene haplotypes, developmental traits, yield components and seed yield.

From laboratory to field - Research on insecticide resistance using the example of a chimeric cytochrome P450 monooxygenase

Development of insecticide resistance in insect pest species is one of the main threats of agriculture nowadays. The cotton bollworm, Helicoverpa armigera, is the noctuid species possessing by far the most reported cases of insecticide resistance worldwide, correlated with one of the widest geographical distributions of any agricultural pest species. This turns H. armigera into an adequate model to study resistance mechanisms in detail. The main mechanisms underlying insecticide resistance are target side insensitivity and metabolism, mainly due to carboxylesterases and cytochrome P450 monooxygenases. Just recently, the resistance mechanism of an Australian H. armigera strain toward the pyrethroid fenvalerate was ascribed to a single P450, CYP337B3. CYP337B3 is a naturally-occurring chimera between CYP337B2 and CYP337B1 evolved by an unequal crossing-over event. This enzyme had acquired new and exclusive substrate specificities resulting in the detoxification of fenvalerate. This is the first known case of recombination as an additional genetic mechanism, besides over-expression and point mutation, leading to insecticide resistance. Therefore, CYP337B1, CYP337B2, and CYP337B3 are ideal candidates for studying structure-function relationships in P450s. The project aims to characterize amino acids that are crucial for the activity of CYP337B3 toward detoxification of fenvalerate. Additionally, cross-resistance conferred by CYP337B3 enables the determination of common structural moieties of pyrethroids favoring detoxification by CYP337B3 and those leading to resistance breaking. Pyrethroids with identified resistance breaking moieties could be used to control even pyrethroid-resistant populations of H. armigera. Another advantage of this system is the conferment of insecticide resistance by CYP337B3 that is not restricted to Australia but seems to be a more common mechanism as recently revealed by the finding of the chimeric P450 in a cypermethrin-resistant Pakistani strain. To shed light on the contribution of CYP337B3 to pyrethroid resistance of H. armigera and even closely related species worldwide, field populations from different countries will be screened by PCR for the presence of CYP337B3 and its parental genes. If applicable, the allele frequency of CYP337B3 will be determined being a convenient method to conclude the resistance level of the tested populations. Finally, the project will result in advising farmers on the control of populations of H. armigera and related species possessing CYP337B3. This will even become more important due to the climate change allowing H. armigera to spread northward including central Europe, where H. armigera is not yet able to survive wintertime.

Multibeam bathymetry processed data (KONGSBERG EM712 working area dataset) of RV HEINCKE during cruise HE622, east Steingrund, North Sea

Multibeam bathymetry processed data (KONGSBERG EM712 multibeam echosounder) was collected onboard RV HEINCKE on two different days during cruise HE622 in the German North Sea (2023-06-06 - 2023-06-20). The raw data (.all format) were processed using QPS Qimera software (v 1.7), based on the following workflow: 0.Raw data > 1.Apply correct Sound Velocity Profiles -> 2.Create dynamic surface (shallow Mode) -> 3.Apply Spline Filter (Medium/Weak) > 4. Finalize with manual 2D and 3D editing, -> 5.Export in GeoTIFF format and projected in the UTM32N coordinate system (EPSG:32632). The bathymetry dataset here is gridded at 0.50 m resolution. The data products were created in the context of the DAM (German Marine Research Alliance), CONMAR research project.

Der Kartendienst stellt die EU-Badegewässer des Freistaates Sachsens dar. Das sind Seen und Talsperren, die bei der Europäischen Kommission als überwachungspflichtige Gewässer - sogenannte »EU-Badegewässer« - gemeldet sind. Bei den EU-Badegewässern handelt es sich um stark durch die Badegäste frequentierte Seen und Talsperren, die in der Regel über eine gute Infrastruktur verfügen und in denen behördlicherseits das Baden ausdrücklich gestattet ist. Diese Gewässer zeichnen sich durch eine ausgezeichnete Wasserqualität aus. Jährlich werden die zu überwachenden Badegewässer im Sächsischen Amtsblatt bekanntgegeben.
