a recessive mutation in the KAKTUS (KAK) gene that suppressed dwarfism and the collapsed xylem character, the cause of decreased hydraulic conductivity in the esk1-5 mutant.

By over-expression of CBF-related genes combining together with suppression of ESK1 gene, the significant increase of plant drought tolerance has been achieved in comparison to single gene manipulation, although the effect is not in an additive way. [ESKMO1] [ESK1]
Title: Increased drought tolerance through the suppression of ESKMO1 gene and overexpression of CBF-related genes in Arabidopsis.

ESK1/TBL29 is involved in the O-acetylation of a wall polysaccharide and that the observed esk1/tbl29 stress phenotypes are a result of a reduction/loss of O-acetyl substituents. [TBL29]
Title: Xylan O-acetylation impacts xylem development and enzymatic recalcitrance as indicated by the Arabidopsis mutant tbl29.

Results indicate that ESK1 was localized in the Golgi, the site of xylan biosynthesis, and that ESK1 is a putative xylan acetyltransferase required for 2-O- and 3-O-monoacetylation of xylosyl residues
Title: The Arabidopsis DUF231 domain-containing protein ESK1 mediates 2-O- and 3-O-acetylation of xylosyl residues in xylan.

ESK1 is necessary for the production of functional xylem vessels, through its implication in the laying down of secondary cell wall components
