A powdery mildew resistance gene QPm.tut-4A was recently, mapped at the end of wheat 4AL chromosome in owm169 - owm228 region. 680 kbp of the sensitive cv. Chinese spring comprise 71 predicted genes from which only 20 have slight homology with 480 kbp of homologous region of resistant T. militinae. In the region 73 genes were predicted. Out of these eight were found similar to retrotransposons, 16 were found just hypothetical, 12 are carrying LRR . . .

Although we have already defined the existence of significant inter-species variability in coeliac reactivity of wheat grain, as well as intraspecies variability of this parameter in common cultivars of hexaploid T. aestivum, we are still missing the description of genetic principles that determines such variability. The desccription of such principles would find a use in further breeding activities leading to cultivar with decreased coeliac reactivity . . .
