Ultracentrifugation of microsomes treated with Triton X-100 revealed three opalescence zones containing rafts in 15%, 25%, and 35% sucrose gradients. When individual raft fractions were added to the mitochondrial DNA import system in organello, their ability to enhance DNA import activity to varying degrees (from 4 to 23 times, depending on their membrane origin) was established.</p></abstract><trans-abstract xml:lang="ru"><p>Изучено влияние микросом и изолированных из них липидных рафтов на импорт ДНК в митохондрии картофеля (Solanum tuberosum L.).
