Dr. Alla Solovyeva research conducted at the Department of Biochemistry and Molecular Biology, All-Russian N.I. Vavilov Institute of Plant Genetic Resources (VIR), focuses on the biochemical characterization and evaluation of global plant genetic resources, with an emphasis on vegetable crops. The work involves comprehensive biochemical screening of cultivated and wild plant accessions to identify valuable genetic materials for breeding and practical applications in agriculture, medicine, and food industries. Research directions include studying nutrient, antinutrient, and biologically active substances in major and minor vegetable crops such as beet, cabbage, tomato, cucumber, pumpkin, lettuce, and amaranth. Advanced analytical techniques including spectrophotometry, gas-liquid chromatography, and high-performance liquid chromatography (HPLC) are utilized for the extraction, purification, and identification of key biochemical compounds. Investigations explore the genetic diversity, nutritional value, and bioactive potential of these crops, focusing on the accumulation of anthocyanins, carotenoids, glucosinolates, and other phytochemicals. The research aims to uncover genetic mechanisms regulating the biosynthesis of these compounds and their role in plant quality, stress tolerance, and pest resistance. This work contributes to understanding the biochemical basis of genetic biodiversity and supports modern breeding programs targeting improved crop quality, biofortification, and sustainable agricultural development.
