Studying the Supramolecular Organization of Photosynthetic Membranes within Freeze-fractured Leaf Tissues by Cryo-scanning Electron Microscopy Dana Charuvi1,3, Reinat Nevo1, Ifat Kaplan-Ashiri2, Eyal Shimoni2, Ziv Reich1 1Department of Biological Chemistry, Weizmann Institute of Science, 2Department of Chemical Research Support, Weizmann Institute of Science, 3Institute of Plant Sciences, Agricultural Research Organization, Volcani Center Here we describe a procedure for studying freeze-fractured plant tissues. High-pressure frozen leaf samples are freeze-fractured and double-layer coated, yielding well preserved frozen-hydrated samples that are imaged using the cryo-scanning electron microscope at high magnifications with minimal beam damage.
Fluorescence in situ Hybridizations (FISH) for the Localization of Viruses and Endosymbiotic Bacteria in Plant and Insect Tissues Adi Kliot1,2, Svetlana Kontsedalov1, Galina Lebedev1, Marina Brumin1, Pakkianathan Britto Cathrin1, Julio Massaharu Marubayashi1, Marisa Skaljac1,3, Eduard Belausov4, Henryk Czosnek2, Murad Ghanim1 1Department of Entomology, Volcani Center, 2Institute of Plant Sciences and Genetics in Agriculture, Robert H. Smith Faculty of Agriculture, Food and Environment, Hebrew University of Jerusalem, 3Department of Applied Sciences, Institute for Adriatic Crops and Karst Reclamation, 4The Institute of Plant Sciences, Volcani Center We describe here a simple fluorescence in situ hybridization (FISH) method for the localization of viruses and bacteria in insect and plant tissues. This protocol can be extended for the visualization of mRNA in whole mount and microscopic sections.
