2.11 Detection of PTOX contribution in electron transport in SA
To determine the contribution of the PTOX to overall PSII electron transport, the leaves of control and salt-treated SV andSA were vacuum infiltrated with either water or with 5 mMn -propyl gallate (n-PG, 3,4,5-trihydroxy-benzoic acid-n-propyl ester; Sigma) or 50 μM DBMIB (2,5-dibromo-3-methyl-6-isopropyl-p-benzoquinone, Sigma). The stock solutions of n -PG were prepared in ethanol and DBMIB in methanol. All inhibitor solutions were prepared fresh.
