PLANTS have many characteristics allowing the accumulation of somatic mutations: lack of a germ line, open systems of growth, flexible meristem organizations and the fact that most ...
WebCRC gene is essential for female development and plants lacking this will not produce pistils. So cells expressing this gene will give rise to female parts [ref]. Nonetheless mutation happening at any stage of the development of floral meristem can be transmitted to the pollens/ovules if the mutated cells stochastically give rise to that lineage. WebMar 11, 2024 · Abstract. Somatic mutations can have important effects on the life history, ecology, and evolution of plants, but the rate at which they accumulate is poorly …
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 are common in plants, and they may accumulate and be passed on to gametes.
