The secondary cell wall (SCW) of xylem vessel cells provides rigidity and strength that enables efficient water conduction throughout the plant. To gain insight into SCW deposition, we mutagenized Arabidopsis thaliana VASCULAR-RELATED NAC-DOMAIN7-inducible plant lines, in which ectopic protoxylem differentiation is synchronously induced. baculites mutant was isolated based on absence helical patterns ectopically-induced cells, mature plants exhibited an irregular (irx) phenotype plants.

Abstract Xylem vessels function in the long-distance conduction of water land plants. The NAC transcription factor VASCULAR-RELATED NAC-DOMAIN7 (VND7) is a master regulator xylem vessel cell differentiation Arabidopsis (Arabidopsis thaliana). We previously isolated suppressor ectopic induced by VND7 (seiv) mutants. Here, we report that responsible genes for seiv3, seiv4, seiv6, and seiv9 are protein ubiquitination-related encoding PLANT U-BOX46 (PUB46), an uncharacterized F-BOX (FBX), PUB36,...
The plant-specific NAC transcription factor VASCULAR-RELATED NAC-DOMAIN 7 (VND7) functions in xylem vessel cell differentiation Arabidopsis thaliana. To identify novel factors regulating differentiation, we previously performed ethyl methanesulfonate mutagenesis of a transgenic 35S::VND7-VP16-GR line which VND7 activity can be induced post-translationally by glucocorticoid treatment. We successfully isolated mutants that fail to form ectopic cells named seiv (suppressor VND7) mutants. Here,...
