The aim of the research was to assess genetic diversity of 71 accessions from the he Former Yugoslav Republic of Macedonia using 13 microsatellite and 16 morphological markers. The average number of alleles per microsatellite was 5.8. The relationship among the studied accessions was assessed by hierarchical cluster analysis. A very clear separation of accessions into two groups was observed in the UPGMA dendrogram. The larger represented Andean gene pool and contained 40 accessions (56% of total), while the other 31 accessions (44% of total) composed Mesoamerican gene pool. The two groups were successfully discriminated by eight morphological traits. Within the larger Andean cluster a sub-group of 16 climbing accessions was separated from 24 bush accessions. The absence of the string in the pods of the climbers suggests that this sub-group comprises snap beans grown primarily for their fresh pods. Eight morphological traits distinguished the two Andean sub-groups. Assessment of genetic relationship among accessions, their classification into respective gene pool and identification of morphological peculiarities provided valuable information for the management of plant gene bank and Macedonian bean breeding program.

In this study proteome changes in the stem of common bean (Phaseolus vulgaris L., cv. Tiber) under drought stress has been analysed. Proteins with changed abundance under drought have been identified with quantitative proteomic analysis and were grouped into several functional groups, mainly into energy metabolism, photosynthesis, proteolysis, protein synthesis and proteins related to defence and stress. The results of the study will contribute to understanding of mechanisms underlying drought stress tolerance in common bean and lead to identification of potential markers whose changes in abundance can be associated with quantitative characteristics used for description of stress tolerance on the genotype level. The results of the research have gained important information that will assist in the evaluation of core collection or subcollection of the present project, which will include accessions with properties such as tolerance to drought. Cultivar Tiber is already included in the core collection as tolerant cultivar.
