Recovery of Somatic Variation in Resistance of Populus to Septoria Musiva
Tissue culture has been used primarily to clonally propagate plants. However, genetic variation has been observed among regenerated plants. Passage of plant cells through a tissue culture cycle can result in increased spontaneous phenotypic and genetic variation. Somaclonal variation is the term used to describe variation exhibited by plants obtained from aseptic culture (Larkin and Scowcroft, 1981). Somatic variation is now considered a general phenomenon and somaclonal variation in disease resistance has been observed in many agronomic crops (Larkin, 1987).
