Web28 apr 2010 · Sultr4;1is strongly expressed during seed filling. We first analysed by Real-Time Quantitative Reverse Transcription-PCR (qRT-PCR) gene expression levels of the Arabidopsis sulphate transporters belonging to group 4 (SULTR4;1 and SULTR4;2) (Figure 1).The analysis was performed on isolated seeds [7 and 10 days after flowering (DAF) … WebArabidopsis mutants lacking root hairs have no acidic xyloglucan. A loss-of-function mutation in At1g63450, a root hair-specific gene encoding a family GT47 glycosyltransferase, results in the synthesis of xyloglucan that lacks galacturonic acid. The root hairs of this mutant are shorter than those of the wild type.

Elongation growth, leaf movement, and changes in flowering time are among the best-studied responses to high temperature and heat stress in this species. Web16 nov 2012 · Arabidopsis PDK1 was also found to bind to phosphoinositides and PA in lipid-overlay assays through a PH domain present at its C-terminus (Deak et al., 1999). Importantly, only binding to PA stimulates PDK1 activity in a kinase assay ( Anthony et al., 2004 ; Otterhag et al., 2006 ), suggesting that PDK1 activity might be restricted to …
