... mutation may affect certain aspects of barley disease resistance, while it remains to be determined, if the effect on disease resistance is a direct response to changes in SA signaling. Background To ... H 2 O 2 accumulation in mesophyll cells leads to induction of glutathione during the hyper-sensitive response in the barley- powdery mildew interaction. Plant Physio...

... Yap1 to the GSH1 promoter could be repressed by Cbf1, a DNA-binding protein that binds to elements in the vicinity of Yap1 binding site [52]. Alternatively, the increased reducing power of tsa1 mutant, ... glucose. In this case, cells were grown in raffinose medium. Again, these mutants grew simi- larly to the wild-type cells (data not shown), dismissing the involvement of Msn...

... of PDZ binding on the interactions of the Grb4-SH2 domain with the ephrinB2(301–333)-pY304 peptide. (A) The PDZ- binding curves are for the fluorescein-labeled peptides including eph- rinB2(301–333) ... Thus, the conformation of the PDZ binding domain of eph- rinB2(301–333) is essentially independent of tyrosine phosphorylation within the SH2-binding element of eph- rinB2(301–3...
