На основе секвенирования генов гомологов (ETC3-1 и ЕТС3-2 MYB-like ТФ ETC3 у перца и SmeATV MYB-like ТФ у баклажана) у форм с различным накоплением антоцианов в вегетативных органах и плодах выявлены аллели, детерминирующие синтез нефункциональных аминокислотных последовательностей, связанных с повышением накопления антоцианов у перца, усилением репрессии синтеза антоцианов у баклажана. Разработаны молекулярные маркеры к аллелям генов-гомологов, позволяющие дифференцировать селекционный материал по накоплению антоцианов в плодах и вегетативных органах. </p></abstract><trans-abstract xml:lang="en"><p>This paper presents study results on the polymorphism of Atroviolacea (ATV) Solanum lycopersicum gene orthologs in pepper (genus Capsicum) and eggplant (S. melongena), as well as the developments in molecular markers associated with anthocyanin accumulation in various parts of these crops, whose fruits, along with tomatoes, constitute important vegetable products for functional nutrition. Based on sequencing of homologous genes (ETC3-1 and ETC3-2 MYB-like transcription factor (TF) ETC3 in pepper, and SmeATV MYB-like TF in eggplant) in accessions with varying levels of anthocyanin accumulation in vegetative organs and fruits, alleles leading to the synthesis of nonfunctional amino acid sequences have been identified; these are associated with increased anthocyanin accumulation in pepper and with enhanced repression of anthocyanin synthesis in eggplant. Molecular markers targeting these alleles of the homologous genes have been deve- loped, enabling the discrimination of breeding material according to anthocyanin accumulation in fruits and vegetative organs, have been developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гомология генов</kwd><kwd>Solanum lycopersicum</kwd><kwd>Capsicum annuum</kwd><kwd>Capsicum frutescens</kwd><kwd>Solanum melongena</kwd><kwd>синтез антоцианов</kwd><kwd>ДНК маркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene homology</kwd><kwd>Solanum lycopersicum</kwd><kwd>Capsicum annuum</kwd><kwd>Capsicum frutescens</kwd><kwd>Solanum melongena</kwd><kwd>anthocyanin synthesis</kwd><kwd>DNA markers</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Антиоксидантная активность сортообразцов томата и перца / А.
