However, this approach can be problematic since a high proportion of abnormal somatic embryos occur quite often in tissue culture. Genetic dissection - the isolation and characterization of mutants that are defective in embryogenesis. This approach has concentrated on pattern formation mutants, such as mutants that have altered apical-basal patterns or the radial patterns. State one way that plant development differs from animal development. Therefore, plant body shape is due to the rate and direction of cell division and cell elongation.
Plant development is continuous.
New plant organs are formed throughout their life by clusters of embryonic cells called meristems. Plants have tremendous developmental plasticity. Lost plant parts can be regenerated by meristems, and even entire plants can be regenerated from single cells. In addition, environmental factors such as light and temperature can greatly influence overall plant form.
