Description

Dry seeds of Rumex acetosa L. were treated by two physical agents (β-rays and γ-rays) and two chemical mutagens [methyl methane sulfonate (MMS) and nitroso methylurea (NMU)]. Chromosome aberrations induced in metaphase were recorded in root tip cells of both male and female plants. After β and γ irradiation, no difference between autosomes and sex chromosomes was observed. After MMS and NMU treatment, a higher sensitivity of sex chromosomes was pointed out. These results could be related to the heterochromatine pattern in the genome of both sexes

Abstract (French)

Des graines seches du Rumex acetosa L. ont ete traitees par deux agents mutagenes physiques, les radiations β et γ et par deux agents mutagenes chimiques, le methane sulfonate de methyle (MMS) et la methyl nitroso-uree (MNU). Les taux de lesions chromosomiques induites en metaphase ont ete observes dans les meristemes radiculaires des plantes male et femelle. Apres traitement par les rayons γ et les electrons β, aucune difference de comportement entre autosomes et chromosomes sexuels n'a ete decelee. Par contre, apres traitement par le MMS et la MNU, une sensibilite superieure des chromosomes sexuels a ete mise en evidence. Ces resultats peuvent etre mis en relation avec la repartition de l'heterochromatine dans les genomes males et femelles
