文摘

The anatomical research of the vegetative organs of the cytoplasmatic hybrid grown in vitro and containing the Brassica napus nucleus and the Lesquerella fendleri chloroplasts was carried out and compared to the parental forms. It was found that the anatomical structure of the cybrid is similar to rapeseed. Anomalous changes in the epithelial, parenchymal, and connective tissue of the leaf, stalk, stem, and root of the cybrid were detected. The appearance of the anatomical defects can be explained by nuclear-cytoplasmatic incompatibility, which is the cause of low adaptability of the cybrid to in vivo conditions and takes place due to alien chloroplast gene expression in the remote species.
