The large GTPase AtGBPL3 links nuclear envelope formation to lamina-associated gene silencing [RNA-seq]
Ontology highlight
ABSTRACT: Guanylate Binding Proteins (GBPs) are prominent regulators of immunity unknown to be required for nuclear envelope formation and function. The Arabidopsis GBP orthologue AtGBPL3 was identified as a novel component of the plant lamina, with essential functions in mitotic nuclear envelope reformation. AtGBPL3 is preferentially expressed in mitotically active root tips, accumulates at the nuclear envelope and interacts with further components of the nuclear lamina. To investigate effects of defective lamina components on gene expression, we analysed the transcriptomes of 4 day old wild-type, gbpl3-5, crwn4-1, crwn1-1crwn4-1, as well as gbpl3-5 mutants expressing GBPL3-GFP or the GTPase-dead GBPL3(K83A)-GFP under control of the AtGBPL3-promoter.
