p24 Family Proteins Are Involved in Transport to the Plasma Membrane of GPI-Anchored Proteins in Plants
2020
p24 proteins are a family of type-I membrane proteins that cycle between the endoplasmic reticulum (ER) and the Golgi apparatus via Coat Protein I (COPI)- and COPII-coated vesicles. These proteins have been proposed to function as cargo receptors, but the identity of putative cargos in plants is still elusive. We previously generated an Arabidopsis (Arabidopsis thaliana) quadruple loss-of-function mutant affecting p24 genes from the δ-1 subclass of the p24 delta subfamily (p24δ3δ4δ5δ6 mutant). This mutant also had reduced protein levels of other p24 family proteins and was found to be sensitive to salt stress. Here, we used this mutant to test the possible involvement of p24 proteins in the…
Transient Transformation of A. thaliana Seedlings by Vacuum Infiltration
2020
Transient expression in Arabidopsis thaliana seedlings allows fast expression of fluorescent markers for different subcellular compartments. This protocol describes a transient transformation assay with five-day-old seedlings using Agrobacterium tumefaciens-mediated vacuum infiltration. Three days after infiltration of the Agrobacterium containing an expression vector for a fluorescent marker of interest, cotyledon cells expressing the fluorescent protein can be imaged in a confocal microscope. This assay allows high-throughput screening of new constructs and the study of the localization of a large number of subcellular markers in Arabidopsis seedlings including wild-type, stable over-expr…
