Here, we review rate variation within each of these three components, with an emphasis on plant nuclear genes. Evolutionary rates vary among nucleotide sites as a consequence of selection and mutational biases. Mutation varies among sites as a …

WebSomatic mutations are common in plants, and they may accumulate and be passed on to gametes. The determinants of somatic mutation accumulation include the intraorganismal selective effect of mutations, the number of cell divisions that separate the zygote from … 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 ...
