    Notes: Abstract  Genetic variability among 49 accessions of Triticum urartu was estimated by RFLP and RAPD marker analyses, and the two data sets were compared. One T. timopheevii accession and two accessions of T. durum and T. aestivum, respectively, were included to identify T. urartu accessions closely related to these polyploid wheats. Twenty eight RFLP clones and 29 RAPD primers generated 451 and 155 polymorphic bands, respectively. The three accessions from Armenia clustered together and were well separated from all other accessions, which showed less pronounced geographical patterns. Genetic similarity and co-phenetic values calculated with RAPD markers were very similar to those calculated with RFLP markers for the intraspecific comparisons, but not for the interspecific comparisons. The identification of individual T. urartu accessions which are more related to polyploid wheats than others was not possible.

    Notes: Plants of two wheat cultivars (Triticum aestivum L., cultivars Mec and Chiarano), differing in sensitivity towards sulfur dioxide, were fumigated with 96 nL L-1 of SO2 for four months. Thylakoid membranes were subjected to two-dimensional electrophoresis in order to detect possible changes in the protein patterns. We found the greatest alterations following treatment in the polypeptide profiles of the most sensitive cultivar, Mec, even if some significant changes were also detected in the plants of the cultivar Chiarano.
