In Vitro conservation and genetic diversity analysis of rare species Ribes janczewskii.

ABSTRACT: Ribes janczewskii is a rare and valuable plant known for its resistance to spring frosts, pests, and diseases. It is used in hybridization to develop resistant currant varieties but is on the verge of extinction, listed in Kazakhstan Red Book. This study developed a micropropagation and slow-growth storage protocol for conservation. Genotypes were identified through DNA barcode analysis (rbcL, ITS, and matK) and sequences uploaded to the National Center for Biotechnology Information database. Genetic diversity was assessed using iPBS primers, generating 98 fragments with 88-94% polymorphic bands. Biochemical analysis of fruits showed vitamin C content from 4.64 to 5.61 mg/100 g, vitamin E from 2.26 to 3.16 mg/100 g, vitamin B5 from 3.18 to 4.93 mg/100 g, and quercetin up to 12.5 mg/100 g.
