This genome although rather large for a mammalian mtDNA 17 300 bp IS organized in the typical vertebrate fashion. For each of 6 wild and 5 domestic rabbits belonging respectively to the subspecies Oryctolagus cuniculus algirus and Oryctolagus cuniculus cuniculus rntDNA molecules are heterogeneous in size. The length variations of about 100 bp have been assigned to the main non coding region of the genome. Very curiously according to these preliminary results the mtDNAs of the two subspecies exhibit similar restriction patterns. However 2 variants were found among the animals examined one in each population. Key words Rabbit mitochondrial DNA restriction endonuclease. Résumé ADN mitochondrial du lapin comparison préliminaire entre animaux domestiques et sauvages La carte de restriction de 1 ADN mitochondrial ADNmt du lapin a été réalisée 41 sites générés par 13 enzymes de restriction ont été cartographies. Bien qu etant assez long pour un ADN mitochondrial de mammifere 17 300 pb ce genome semble être organise de la même manière que celui des autres vertébrés. Pour chacun des lapins étudiés 6 sauvages et 5 domestiques appartenant respectivement aux sous-espèces Oryctolagus cuniculus algirus et Oryctolagus cuniculus cuniculus les molécules d ADNmt isolees n ont pas toutes la meme longueur. Un allongement variable de 1 ordre de 100 bp au plus de la region non codante du génome est responsible de ces variations de longueur. Curieusement d apres ces .
