Abstract
Berry crops of the genera Fragaria (strawberry; Rosaceae), Rubus (brambles: raspberry and blackberry; Rosaceae) and Vaccinium (blueberry, cranberry and lingonberry; Ericaceae) are of commercial importance worldwide.
They play important roles in anti-tumor, anti-ulcer, anti-oxidant and anti-inflammatory activities.
In vitro culture has become an important tool for the rapid propagation of berry crops, although clonal fidelity is a major concern in commercial micropropagation.
In vitro-derived variations (somaclonal variations) are both heritable (genetic) and nonheritable (epigenetic), and depend on a number of factors, including genotype, chimeric tissue availability, media type, explant origin and type, plant growth regulator concentration, culture environment and duration.
Tissue culture berry crops may show increased growth, berry production, and antioxidant activity, which may be of practical benefit to growers.
The present review provides critical information for a better understanding of micropropagation and its epigenetic effects on morphology and antioxidant properties, along with DNA methylation in berry crops, and fills the prevailing gap in the literature.
