Plant Endoplasmic Reticulum

Abstract

Based in part on the previous version of this eLS article 'Plant Endoplasmic Reticulum' (2001) by Jurgen Denecke.The plant endoplasmic reticulum (ER) is responsible for the synthesis and often storage of a large group of proteins and lipids that enter the secretory pathway. This multifunctional organelle, which also represents one of the calcium storage compartments in plant cells, has currently received considerable attention from the research community because of features unique to plants that make it particularly interesting for biotechnology. Here, the principles behind ER dynamics in plants, and the molecular factors that control the rapid remodelling and network configuration of the organelle are discussed. Correlations between ER morphology and function indicate the potential to enhance protein storage by merely increasing the capacity of the organelle through altering its shape.

Characterization of the Transcriptome and Proteome of Brassica napus Reveals the Close Relation between DW871 Dwarfing Phenotype and Stalk Tissue

“…Plant ER can control the modification of polysaccharides and the composition of the cell wall to achieve the purpose of regulating the elongation of the cell wall [ 33 ]. When the Arabidopsis ER transmembrane protein is misexpressed, Arabidopsis and its control group exhibit significant differences, including defects in cell elongation, abnormally thickened secondary walls, and extreme dwarf [ 34 ].…”
