WebAbstract. It is hypothesised that somatic mutations are an important source of genetic variance within long-lived plant individuals, and that shoot ontogeny and sexual reproduction are two processes that decrease the mutation load of the shoot population and the offspring. This paper focuses on the way in which sympodial and monopodial shoot ... WebSomatic mutations arising in plants can be inherited by naturally occurring mechanisms of sexual and asexual reproduction. Long life span, large clone size, and the complete regeneration of buds each year may permit an indivdual plant or clone to evolve. Plants may even develop as mosaics of genetic variation.
