The genomes of several species of the genus Arachis, contain homologues of agrobacterial cucumopine synthase (cus) and synthase of deoxyfructosylglutamine (mas2`) genes. There are full-length cus genes with intact ORFs in A.duranensis, A. stenosperma, A. hypogaea and A. monticola. However, whether the gene is being expressed has remained to be unknown. Within the framework of this research, the expres-sion of the cus gene in various organs of 9 lines of cultivated peanuts from the VIR collection was investigated. Studied lines have different morphological characteristics and geographic origins. Tis-sue-specific expression of the cus gene in peanut samples was revealed and lines contrasting in the level of its expression were found. The highest level of expression was observed in the roots. A pre-liminary assessment of economically valuable traits of peanuts (maturity, yield) when growing plants on nitrogen-rich soils does not show their relationship with the intensity of expression of the cus gene.
