Selective Knockdowns in Maize by Sequence-Specific Protein Aggregation.
Selective Knockdowns in Maize by Sequence-Specific Protein Aggregation.
Methods Mol Biol. 2018;1676:109-127
Authors: Betti C, Schymkowitz J, Rousseau F, Russinova E
Abstract
Protein aggregation is determined by 5-15 amino acids peptides of the target protein sequence, so-called aggregation-prone regions (APRs) that specifically self-associate to form β-structured inclusions. The presence of APRs in a target protein can be predicted by a dedicated algorithm, such as TANGO. Synthetic aggregation-prone proteins are designed by expressing specific APRs fused to a fluorescent carrier for stability and visualization. Previously, the stable expression of these proteins in Zea mays (maize) has been demonstrated to induce aggregation of target proteins with specific localization, such as the starch-degrading enzyme α-glucan water dikinase, giving rise to plants displaying knockdown phenotypes. Here, we describe how to design synthetic aggregation-prone proteins to harness the sequence specificity of APRs to generate aggregation-associated phenotypes in a targeted manner and in different subcellular compartments. This method points toward the application of induced targeted aggregation as a useful tool to knock down protein functions in maize and to generate crops with improved traits.

Abstract
iNKT cells play important roles in immune regulation by bridging the innate and acquired immune systems. The functions of iNKT cells have been investigated in mice lacking the Traj18 gene segment that were generated by traditional embryonic stem cell technology, but these animals contain a biased T cell receptor (TCR) repertoire that might affect immune responses. To circumvent this confounding factor, we have generated a new strain of iNKT cell-deficient mice by deleting the Traj18 locus using CRISPR/Cas9 technology, and these animals contain an unbiased TCR repertoire. We employed these mice to investigate the contribution of iNKT cells to metabolic disease and found a pathogenic role of these cells in obesity-associated insulin-resistance. The new Traj18-deficient mouse strain will assist in studies of iNKT cell biology.

Abstract
BACKGROUND: With 15,949 markers, the low-density Infinium QC Array-24 BeadChip enables linkage analysis, HLA haplotyping, fingerprinting, ethnicity determination, mitochondrial genome variations, blood groups and pharmacogenomics. It represents an attractive independent QC option for NGS-based diagnostic laboratories, and provides cost-efficient means for determining gender, ethnic ancestry, and sample kinships, that are important for data interpretation of NGS-based genetic tests.
METHODS: We evaluated accuracy and reproducibility of Infinium QC genotyping calls by comparing them with genotyping data of the same samples from other genotyping platforms, whole genome/exome sequencing. Accuracy and robustness of determining gender, provenance, and kinships were assessed.
RESULTS: Concordance of genotype calls between Infinium QC and other platforms was above 99%. Here we show that the chip's ancestry informative markers are sufficient for ethnicity determination at continental and sometimes subcontinental levels, with assignment accuracy varying with the coverage for a particular region and ethnic groups. Mean accuracies of provenance prediction at a regional level were varied from 81% for Asia, to 89% for Americas, 86% for Africa, 97% for Oceania, 98% for Europe, and 100% for India. Mean accuracy of ethnicity assignment predictions was 63%. Pairwise concordances of AFR samples with the samples from any other super populations were the lowest (0.39-0.43), while the concordances within the same population were relatively high (0.55-0.61). For all populations except African, cross-population comparisons were similar in their concordance ranges to the range of within-population concordances (0.54-0.57). Gender determination was correct in all tested cases.
CONCLUSIONS: Our results indicate that the Infinium QC Array-24 chip is suitable for cost-efficient, independent QC assaying in the settings of an NGS-based molecular diagnostic laboratory; hence, we recommend its integration into the standard laboratory workflow. Low-density chips can provide sample-specific measures for variant call accuracy, prevent sample mix-ups, validate self-reported ethnicities, and detect consanguineous cases. Integration of low-density chips into QC procedures aids proper interpretation of candidate sequence variants. To enhance utility of this low-density chip, we recommend expansion of ADME and mitochondrial markers. Inexpensive Infinium-like low-density human chips have a potential to become a "Swiss army knife" among genotyping assays suitable for many applications requiring high-throughput assays.

Abstract
Aspergillus niger secretes proteins throughout the colony except for the zone that forms asexual spores called conidia. Inactivation of flbA that encodes a regulator of G-protein signaling results in colonies that are unable to reproduce asexually and that secrete proteins throughout the mycelium. In addition, the ΔflbA strain shows cell lysis and has thinner cell walls. Expression analysis showed that 38 predicted transcription factor genes are differentially expressed in strain ΔflbA. Here, the most down-regulated predicted transcription factor gene, called fum21, was inactivated. Growth, conidiation, and protein secretion were not affected in strain Δfum21. Whole genome expression analysis revealed that 63 and 11 genes were down- and up-regulated in Δfum21, respectively, when compared to the wild-type strain. Notably, 24 genes predicted to be involved in secondary metabolism were down-regulated in Δfum21, including 10 out of 12 genes of the fumonisin cluster. This was accompanied by absence of fumonisin production in the deletion strain and a 25% reduction in production of pyranonigrin A. Together, these results link FlbA-mediated sporulation-inhibited secretion with mycotoxin production.

The ins and outs of Ca(2+) in plant endomembrane trafficking.
The ins and outs of Ca(2+) in plant endomembrane trafficking.
Curr Opin Plant Biol. 2017 Sep 28;40:131-137

Abstract
Trafficking of proteins and lipids within the plant endomembrane system is essential to support cellular functions and is subject to rigorous regulation. Despite this seemingly strict regulation, endomembrane trafficking needs to be dynamically adjusted to ever-changing internal and environmental stimuli, while maintaining cellular integrity. Although often overlooked, the versatile second messenger Ca(2+) is intimately connected to several endomembrane-associated processes. Here, we discuss the impact of electrostatic interactions between Ca(2+) and anionic phospholipids on endomembrane trafficking, and illustrate the direct role of Ca(2+) sensing proteins in regulating endomembrane trafficking and membrane integrity preservation. Moreover, we discuss how Ca(2+) can control protein sorting within the plant endomembrane system. We thus highlight Ca(2+) signaling as a versatile mechanism by which numerous signals are integrated into plant endomembrane trafficking dynamics.
