Abstract

Cache transactions The principle of inheritance first observed by Mendel is clear enough. Genetic information passes from parent to offspring in the DNA carried in the chromosomes found in every cell of the organism — and to a lesser extent in auxiliary genomes in organelles such as mitochondria and chloroplasts. But analysis of revertant hothead gene mutants in Arabidopsis thaliana suggests that these plants can inherit information not found in parental chromosomes, but identical to that of a grandparent or more distant forebear. This may involve template-directed restoration of ancestral DNA passed on in an RNA cache, like a web browser cache that delivers an old page. It will be intriguing to discover if this type of inheritance is widespread. On the cover, a hothead mutant inflorescence (SEM by M. A. Webb).
