 Title    Water Relations in Young Growing Wheat Leaves after Application of (2-Chloroethyl)trimethyl- ammoniumchloride (CCC) to the Roots of Wheat Seedlings  
 Abstract    The influence on the water relations of the third develo­ ping leaf of (2-chloroethyl)trimethylammoniumchloride, a synthetic growth regulator, applied to the roots of young wheat plants (Triticum aestivum L.) has been investigated. The tissue water potential and the pressure potential were found to be reduced by several bars in comparison to the untreated controls, whereas the osmotic potential re­ mained unchanged. The content of soluble reducing sugars was considerably increased in the cell sap of CCC-treated leaves. With this accumulation, however, the turgor was not maintained. Additionally, CCC-treated leaves showed considerably lower transpiration rates and higher diffusive resistance than the controls. Thus, the application of CCC to the roots causes alterations in the water relations of developing wheat leaves, which resemble those induced by water deficiency.

 Title    Anthranilate Synthase and Chorismate Mutase Activities in Stem Rust-Inoculated and Elicitor-Treated Resistant, Moderately Resistant, and Susceptible Near-Isogenic Wheat Lines  
 Abstract    Anthranilate synthase and chorismate mutase activities which control the flow of substrate from chorismate into the tryptophan pathway and into the phenylalanine/tyrosine pathway, respectively, were examined in three near isogenic wheat lines of Triticum aestivum L. (cv. Prelude Sr5, highly resistant to stem rust infection; cv. Prelude Sr24, moderately resistant; cv. Prelude srx, susceptible). The activities of both enzymes were found to increase in re­ sponse to inoculation with the stem rust fungus Puccinia graminis f. sp. tritici or treatment with Pgt elicitor. Thus, both the tryptophan branch and the phenylalanine branch appear to contribute to the resistance response in wheat leaves. Only the cytosolic but not the plastidic fraction of the enzyme activities appears to be affected by fungal infection or elicitor treat­ ment. Some differences with respect to degree and time dependency of enzyme activation were noticed between the three wheat lines following inoculation but not after treatment with the Pgt elicitor.
