  Methylated RNA Immunoprecipitation Assay to Study m⁵C Modification in Arabidopsis Eleftheria Saplaoura*¹, Valentina Perrera*², Friedrich Kragler^{1 1}Max Planck Institute of Molecular Plant Physiology, ²Department of Molecular Medicine, Medical School, University of Padua The methylated RNA immunoprecipitation assay is an antibody-based method used to enrich for methylated RNA fragments. Coupled with deep sequencing, it leads to the identification of transcripts carrying the m⁵C modification.

  A Multi-Omics Extraction Method for the In-Depth Analysis of Synchronized Cultures of the Green Alga Chlamydomonas reinhardtii Umarah Mubeen¹, Lais Albuquerque Giraldi¹, Jessica Jüppner¹, Patrick Giavalisco^{1,2 1}Max Planck Institute of Molecular Plant Physiology, ²Max Planck Institute of Biology of Ageing System-wide analysis of multiple biomolecules is crucial to gain functional and mechanistic insights into biological processes. Hereby, an extensive protocol is described for high throughput extraction of lipids, metabolites, proteins and starch from a single sample harvested from synchronized Chlamydomonas culture.

  2 in 1: One-step Affinity Purification for the Parallel Analysis of Protein-Protein and Protein-Metabolite Complexes Marcin Luzarowski*¹, Izabela Wojciechowska*¹, Aleksandra Skirycz^{1 1}Max Planck Institute of Molecular Plant Physiology Protein-protein and protein-metabolite interactions are crucial for all cellular functions. Herein, we describe a protocol that allows parallel analysis of these interactions with a protein of choice. Our protocol was optimized for plant cell cultures and combines affinity purification with mass spectrometry-based protein and metabolite detection.

  High-resolution Single Particle Analysis from Electron Cryo-microscopy Images Using SPHIRE Toshio Moriya¹, Michael Saur¹, Markus Stabrin¹, Felipe Merino¹, Horatiu Voicu², Zhong Huang², Pawel A. Penczek², Stefan Raunser¹, Christos Gatsogiannis^{1 1}Department of Structural Biochemistry, Max Planck Institute of Molecular Physiology, ²Department of Biochemistry and Molecular Biology, The University of Texas Medical School at Houston This paper presents a protocol for processing cryo-EM images using the software suite SPHIRE. The present protocol can be applied for nearly all single particle EM projects that target near-atomic resolution.

  A Protocol for the Identification of Protein-protein Interactions Based on ¹⁵N Metabolic Labeling, Immunoprecipitation, Quantitative Mass Spectrometry and Affinity Modulation Stefan Schmollinger^1,2, Daniela Strenkert^1,2, Vittoria Offeddu^1,2, André Nordhues^1,2, Frederik Sommer^1,2, Michael Schroda^{1,2 1}Max Planck Institute of Molecular Plant Physiology, ²University of Kaiserslautern We present a variation of the QUICK (QUantitative Immunoprecipitation Combined with Knockdown) approach that was introduced previously to distinguish between true and false protein-protein interactions. Our approach is based on ^15N metabolic labeling, the modulation of affinities of protein-protein interactions by the presence/absence of ATP, immunoprecipitation, and quantitative mass spectrometry.
