Earlier, a SSAP (sequence specific amplified polymorphism) analysis revealed localization of the cdt locus in VI linkage group. For fine mapping of the cdt locus a set of PCR based markers was developed. PCR markers were based on known sequences of pea genes, which were determined using analysis of genome microsynteny between pea and model legume Medicago truncatula. The close linkage of the cdt locus and markers based on the Pentatricopeptide repeat and Exosome complex exonuclease RRP 45 genes was revealed. Thus, prerequisites for cdt positional cloning were developed.</p></abstract><trans-abstract xml:lang="ru"><p>У гороха посевного описан мутант SGECdt (cdt), характеризующийся повышенным уровнем накопления кадмия и устойчивостью к данному тяжелому металлу, по сравнению с исходной линией. Проведенный ранее SSAP анализ позволил локализовать локус cdt в VI группе сцепления гороха. Для более подробного картирования локуса cdt были разработаны молекулярные маркеры, основанные на известных последовательностях генов гороха, выявленных с помощью анализа геномной микросинтении между горохом посевным и модельным бобовым Medicago truncatula. Было выявлено тесное сцепление локуса cdt и маркеров, разработанных на основе генов Pentatricopeptide repeat и Exosome complex exonuclease RRP45. Таким образом, были созданы условия для дальнейшего позиционного клонирования гена cdt.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Pisum sativum L.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>генетический анализ устойчивости к кадмию</kwd><kwd>ЛОКАЛИЗАЦИЯ ГЕНОВ</kwd><kwd>SNP (SINGLE NUCLEOTIDE POLYMORPHISM) МАРКЕРЫ</kwd><kwd>CAP S (CLEAVED AMPLIFIED POLYMORPHIC SEQUENCES) МАРКЕРЫ</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кулаева О.
