Figure 1The Arabidopsis pi4kβ1 pi4kβ2 double mutant displays a growth defect and cytokinetic defects. The growth phenotype of the Arabidopsis pi4kβ1 pi4kβ2 double mutant can be complemented by ectopic expression of PI4Kβ1 or PI4Kβ2, or by mCherry-tagged PI4Kβ1 expressed from a genomic fragment. Plants shown are one month old. Scale bar, 10 cm. The irregularities in the pattern of root epidermal cell division orientation of the pi4kβ1 pi4kβ2 double mutant is also complemented by ectopic expression of PI4Kβ variants, as shown by propidium iodide (PI) staining of five-day-old roots. Arrowhead, oblique cell wall. Insets, magnifications of areas showing cell wall stubs. Scale bars, 50 µm. Quantifications of cell wall stubs, oblique cell walls and root meristem size (wild type, n = 15 roots; pi4kβ1, n = 15 roots; pi4kβ2, n = 14 roots; pi4kβ1 pi4kβ2, n = 18 roots; pPI4Kβ1:PI4Kβ1, n = 14 roots, pPI4Kβ2:PI4Kβ2, n = 15 roots). n.d., not detected. Data are mean ± SD. Lowercase letters indicate a significant increase of oblique cell walls (Welch ANOVA with Games-Howell post-hoc test; p < 0.0001) or a significant reduction of root meristem size in the pi4kβ1 pi4kβ2 double mutant (one-way ANOVA with post-hoc Tukey HSD; p < 0.001).

Scale bar, 10 cm. Complementation with the pKNOLLE-driven construct indicates functionality of PI4Kβ1 during cell plate formation in G2/M phase. PI staining of pKNOLLE:FLAG-PI4Kβ1 expressed in the pi4kβ1 pi4kβ2 double mutant background indicates rescue of cytokinetic defects. Arrowhead, cell wall stub in the pi4kβ1 pi4kβ2 double mutant. Scale bars, 50 µm.
Figure 7DM leads to increased oxidative stress and substantially increased ROS. High levels of ROS is recognized to induce phosphorylation of p53 (ser15). Mitochondrial dysfunction ensues leading to apoptosis and thrombosis (outlined in red). JNK is stress activated (ROS), leading to autophagy enhancement and formation of autophagosomes. Damaged organelles (including mitochondria) are removed through lysosomal fusion and degradation. Mitophagy protects the platelet from oxidative stress by removing the damaged mitochondria and phosphorylated p53 (outlined in blue).
SARS-CoV-2 genotypes.Figure 2  The heat map shows the position (left to right), identity (top row) and frequency (color code) of variant nucleotide positions detected by SARS-CoV-2 full genome amplicon sequencing in (A) 20 samples of MPP-R workers tested positive on May 20 or 25, (B) 15 samples of MPP-R workers tested positive between June 5 and 17, and (C) two workers from MPP-D who may have transmitted the virus to cases B1 and/or B2. Individual collection dates are shown to the right of each sample. Variant sequences are given relative to the Wuhan reference strain NC_045512. The two silent mutations which define the prototype of the investigated outbreak are marked with an asterisk. Frequencies below 100% mean that only a fraction of viral genomes shows nucleotide variations, indicating the presence of viral intra-host sub-populations. White rectangles denote nucleotide positions which were not covered by amplicon-seq reads within the respective sample. For nucleotide positions in coding regions, the corresponding viral ORF(s) are shown above the variant position. Variants without such information are located in non-coding regions.
Figure 3The ultrastructure of cytokinetic defects was analyzed by transmission electron microscopy of five-day-old root tip meristems. Images shown are from 3 roots (wild type) and 7 roots (pi4kβ1 pi4kβ2 double mutant). In wild type controls (A), vesicles fused at the cell division plane to give rise to tubular network (TN) of a nascent cell plate. White arrowheads, fused vesicles at the division plane. n = 8 cells. In the pi4kβ1 pi4kβ2 double mutant (B), vesicles were delivered to the cell division plane at a similar stage as wild type but did not fuse. The nuclei of both wild type and double mutant cells were at telophase or interphase, as judged by the presence of decondensed chromatin and a nuclear envelope. At this stage, failed cell plate formation was never seen in wild type (A). Black arrowheads, unfused vesicles. n = 6 cells. Unfused vesicles clustered around a cell wall stub (arrow). White arrowheads, light vesicles; black arrowheads, dark vesicles; black arrow, cell wall stub. n = 8 cells. No cross wall was seen in this cell with two nuclei. n = 6 cells. n, nucleus; ne, nuclear envelope. Scale bars in magnified figures, 2 μm; in insets, 1 μm.

Black arrow indicates the increase in inter-TAD interactions. B) Boxplot showing the TAD boundary scores in control and 24hr ActD treated cells. p-value: Wilcoxon rank-sum test. The horizontal bands in the boxplots represent the median, the error bars represent +/- 1.5 x IQR values, and the outer shapes represent the density of the data points. The figures represent data generated from the pooled Hi-C datasets with 2 biological replicates. C) Mean interaction frequencies centered on all TAD boundaries +/- 1Mb for each dataset at 40kb resolution, as well as the log2 ratios. The inter-TAD interactions are increased upon transcriptional inhibition. D) Aggregate Peak Analysis based on the K562 loops coordinates The heatmaps are centered on the loop positions +/- 250kb using 25kb resolution Hi-C data. There is a ~50% reduction of loop intensity as assessed by z-scores and log2 fold change. E) Boxplot showing the TAD boundary scores in control and 24hr ActD treated cells for boundaries that are bound with differing numbers of CTCF binding sites. The reduction of TAD boundary scores upon ActD treatment is independent of CTCF binding. p-value: Wilcoxon rank-sum test. The horizontal bands in the boxplots represent the median, the error bars represent +/- 1.5 x IQR values, and the outer shapes represent the density of the data points. The figures represent data generated from the pooled Hi-C datasets with 2 biological replicates. F) Scaling plot generated by 40kb resolution Hi-C data showing the interaction frequency as a function of genomic distance, with upper distance limit of 3Mb. The 24hr ActD treated samples shows a slower rate of decay at shorter distances, correlating with the reduction of insulation scores.
acetylation (a) HeLa cells constantly expressing HA-tagged PML were depleted for endogenous SUMO1/2/3 by siRNA.Figure 3(a) HeLa cells constantly expressing HA-tagged PML were depleted for endogenous SUMO1/2/3 by siRNA. Subsequently, they were transfected with RGS-His tagged SUMO2T90K for 72 h. Prior to lysis, cells were treated with As2O3 for 2 h. HA-tagged PML was immunoprecipitated via a denaturing HA-IP, which was followed by LysC digestion. Peptides harboring GlyGly-remnants, corresponding to SUMOylation sites, were enriched by GlyGly-IP and the samples were analyzed by LC-MS/MS. (b) Western blot analysis with α-RGS-His and α-HA was performed to monitor poly-SUMOylation of HA-PML. The remaining samples were measured by LC-MS/MS and final data analysis was done with MaxQuant. A K11 SUMOylated SUMO2 peptide was identified and is depicted with an Andromeda score of 49.3. Intensities for this SUMO2 peptide for the control (gray) and arsenic (purple) treated samples are blotted as a bar graph. The diagram shows a representative dataset derived from two replicates. The corresponding peptide is displayed below the graph. The SUMOylation site is marked with SUMO2 (green) and peptide fragment ions are indicated by y- (red) and b- (blue). (c) The degradation of the PML reactive band (~ 120 kDa) was determined by immunoblotting. HeLa cells were either mock transfected or transfected with siRNA directed against SUMO1/2/3. The expression of RGS-His-tagged SUMO2WT or SUMO2K11Q was induced by DOX for 12 h. Prior to lysis, cells were treated with 1 μM As2O3 for 6 h. Western blot analysis for wild-type SUMO2 and SUMO2K11Q were blotted with α-RGS-His. Immunoblotting with α-Tubulin served as a loading control. Immunoblots for knockdown controls (SUMO1 and SUMO2/3) can be found
The ID of TMEM59 is necessary and sufficient for LC3 activation.Figure 2(A) TMEM59 ID is required for HA-LC3 lipidation. 293 cells were transfected with full‐length TMEM59 (FL) or a deleted version lacking the ID (ΔID, Δ263-323), HA-LC3A (left) or HA-LC3B (right) and GST. Cells were lysed for western blotting against the shown molecules.

(C) Quantification of the phenotype in B. Scoring and data expression were as in Figure 1E. (D) TMEM59 ID (amino acids 263-323) suffices for HA-LC3A lipidation. 293 cells were transfected with the indicated CD16:7 chimera (Control: empty chimera) and vectors encoding HA-LC3A and GST, subjected to aggregation with the shown amounts of anti‐CD16 antibody and lysed for western blotting. The right panel shows control WBs demonstrating equal loading (ACTIN), transfection (GST) and chimera expression (CD16) in unaggregated samples, as all experimental points per chimera derive from a single transfection. (E) Comparable surface levels of CD16:7 constructs. Transfected 293 cells were processed for anti‐CD16 flow cytometry. The graph displays percentages of positive cells (left axis) and means of fluorescence of positive cells (MF, right axis) obtained from triplicates. Data are expressed as means ±s.d. of the triplicates. (F) The ID suffices for HA-LC3B lipidation. (G) The ID suffices for GFP-LC3 activation. 293 cells were transfected with the indicated chimeras and GFP-LC3A or GFP-LC3B, aggregated and mounted. Representative confocal microscopy pictures are shown. Activated GFP-LC3 appears as a collapsed mass of indiscernible vacuoles. (H) Quantification of the phenotype in G. As individual vesicles could not be counted, quantification was done as the percentage of transfected cells showing redistributed GFP-LC3. At least 10 different fields were counted (about 400 cells). The experiment was repeated three times. Data are expressed as means ±s.d. of the triplicates.Source data for this figure is available on the online supplementary information page.

Reduced LAMP-2 expression after PINK1 knockdown.Figure 33A) Regular, non-transduced SH-SY5Y cells were cultivated either in RPMI+10% FCS or starved in HBSS medium for 24 and 40 h. The LAMP-2 and actin content were determined by western blotting and the relative LAMP-2 content of untreated cells was set as 1. Starvation enhanced LAMP-2protein levels; n = 3, p<0.05. 3B) Transduced nt and PINK1 knockdown (kd) SH-SY5Y cells were cultivated either in RPMI+5% FCS or starved for 24 h and 40 h in HBSS. The LAMP-2 and actin content were determined by western blotting. A representative blot after 40 h starvation in HBSS is shown on the right. The relative LAMP-2 content of untreated cells was set as 1. Cells with stable PINK1 knockdown exhibited after 40 h a reduced LAMP-2/actin ratio compared to the nt cells; n = 4, p<0.05. 3C) nt and PINK1 knockdown (kd) SH-SY5Y cells were starved for the indicated times with HBSS and afterwards stained for Lamp-2. Micrographs were taken with constant microscopical settings. LAMP-2 positive signals in each cell were quantified with ImageJ as described in Material and Methods. Knockdown of PINK1 resulted in a decreased amount of LAMP-2 positive stainings/cell after starvation; n = 2, at least 8 fields of view/condition, 89-124 cells/condition; 24 h: p<0.001; 40 h: p<0.05. 3D) nt and PINK1 knockdown (kd) SH-SY5Y cells were stained with the photo-reactive dye MTR and either irradiated for 45 min or left untreated. 24 h and 48 h after irradiation the LAMP-2 and actin content were determined by western blotting. A representative blot 48 h after irradiation is shown on the right. The relative LAMP-2 content of untreated cells was set as 1. Cells with stable PINK1 knockdown exhibited after 48 h a reduced Lamp-2/actin ratio compared to the control (nt) cells; n = 5, p<0.001. 3E) Acid phosphatase activity as parameter for lysosomal activity was quantified in nt and PINK1 knockdown (kd) SH-SY5Y cells cultivated in RPMI medium with 5% FCS. The phosphatase activity was measured and normalized to the protein content. The phosphatase activity of nt cells was set as 1. PINK1 knockdown mediated a reduction of lysosomal activity; n = 3; p<0.05.

The first cluster (BC-1) is composed of 6 K/R residues, the second cluster (BC-2) of 3 K/R residues and the third cluster (BC-3) of 5 K/R residues. The scheme shows the full-length bem1 constructs where none, one or all BCs were mutated. B Percentage of the different full-length bem1 bc mutants associated with liposomes containing 75% PC 20% PS and 5% PI4P. C Fluorescence intensity change associated with the nucleotide exchange of GDP-Cdc42 for mant-GTP Cdc42. Fluorescence was measured after the addition of GDP-Cdc42 to reactions containing Mant-GTP (100 nM), GMP-PNP (100 µM) and the proteins indicated. D Ten-fold serial dilutions of cells and subsequent colony formation on the indicated plates, where expression of wild type GALp-CDC42 is either induced in the presence of Gal or repressed in Dex. Note how mutation of the wild type Cdc42 (KKSKK) to MMSMM is lethal (see blue box), whereas appending the Bem1 BC-1 motif to this cdc42 mutant restores viability (red box). E Representative images of the mEOS-cdc42 mutants signal (cyan) after inducing the expression of GAL1p-CDC42 in the presence of Gal or repressing it in the presence of Dex. The cells in the blue and red boxes correspond to the cells in the blue and red box in panel (D).
