The correlation between the chromosome variation in callus and genotype of explants of Arabidopsis thaliana.

Abstract excerpt

Twelve callus lines of Arabidopsis thaliana were derived from four types of explants excised from diploid plants of two ecotypes (Columbia and Wilna) and autotetraploid plants of the Wilna ecotype. Cytogenetic analysis of the chromosome variation in particular callus lines was carried out for primary culture and callus during 5 months of culture. Ploidy levels of interphase nuclei were estimated by counting the...
