Aim. The aim of the study was to compare diversity of groups of winter common wheat varieties of the Steppe and the Central Forest-Steppe of Ukraine by storage protein loci and some disease resistance genes and to reveal peculiarities of varieties released after 1995. Methods. SDS and APAG electrophoresis was used to identify genotypes at the Glu-1, Gli-1, and some minor gliadin loci. PCR analysis was employed to study alleles of the disease resistance genes Lr34/Yr18/Pm38/Sr57/Bdv1, Tsn1, Tsc2, TDF_076_2D, and Cre-8. Results. Significant differences in frequencies of alleles at most marker loci were revealed. Nonrandom associations between disease resistance gene alleles as well as storage protein alleles were detected. Conclusions. The retention of a set of predominant alleles of a certain zone in different periods of breeding was confirmed. The appearance of new allele associations in the groups of varieties of the Steppe (in particular Gli-A1g and Glu-B1al) and the Central Forest-Steppe (1AL/1RS and Glu-B1d) in the last two decades was noted. Keywords: Triticum aestivum L., varieties, storage proteins, resistance genes, alleles.

Common bacterial blight (CBB), bacterial brown spot (BBS), and halo blight (HB), incited by the bacterial pathogens Xanthomonas campestris pv. phaseoli (Smith) Dye, Pseodomonas syringae pv. syringa, and Pseudomonas syringae pv. phaseolicola, respectively are important diseases of common bean. In addition three fungal pathogens, web blight (WB) Thanatephorus cucumeris, rust Uromyces appendiculatus, and white mold (WM) Sclerotinia sclerotiorum, are also destructive diseases attacking common bean. Bean common mosaic virus is also one of most major virus disease. Resistance genes (QTLs and major genes) to three bacterial (CBB, BBS, and HB), three fungal (WB, rust, and WM), and one viral pathogen (BCMV) were previously mapped in two common bean populations (BAC 6 × HT 7719 and Belneb RR-1 × A55). The objective of this research was to use an integrated RAPD map of the two populations to compare the positions and effect of resistance QTL in common bean. Results indicate that two chromosomal regions associated with QTL for CBB resistance mapped in both populations. The same chromosomal regions associated with QTL for disease resistance to different pathogens or same pathogens were detected in the integrated population.

Abstract The RPS5 disease resistance gene of Arabidopsis mediates recognition of Pseudomonas syringae strains that possess the avirulence gene avrPphB. By screening for loss of RPS5-specified resistance, we identified five pbs (avrPphB susceptible) mutants that represent three different genes. Mutations in PBS1 completely blocked RPS5-mediated resistance, but had little to no effect on resistance specified by other disease resistance genes, suggesting that PBS1 facilitates recognition of the avrPphB protein. The pbs2 mutation dramatically reduced resistance mediated by the RPS5 and RPM1 resistance genes, but had no detectable effect on resistance mediated by RPS4 and had an intermediate effect on RPS2-mediated resistance. The pbs2 mutation also had varying effects on resistance mediated by seven different RPP (recognition of Peronospora parasitica) genes. These data indicate that the PBS2 protein functions in a pathway that is important only to a subset of disease-resistance genes. The pbs3 mutation partially suppressed all four P. syringae-resistance genes (RPS5, RPM1, RPS2, and RPS4), and it had weak-to-intermediate effects on the RPP genes. In addition, the pbs3 mutant allowed higher bacterial growth in response to a virulent strain of P. syringae, indicating that the PBS3 gene product functions in a pathway involved in restricting the spread of both virulent and avirulent pathogens. The pbs mutations are recessive and have been mapped to chromosomes I (pbs2) and V (pbs1 and pbs3).
