Abstract

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 branching may influence intra-plant genetic variation and on the role of physiological integration between plant modules for the phenotypic expression of this variation. I also discuss some possible consequences of the interaction of somatic mutations and shoot ontogeny for the study of seedling recruitment and phenotypic plasticity in plant populations.

Key words
