Chromatin dynamics during plant sexual reproduction
Plants have the remarkable ability to establish new cell fates throughout their life cycle, in contrast to most animals that define all cell lineages during embryogenesis. This ability is exemplified during sexual reproduction in flowering plants where novel cell types are generated in floral tissues of the adult plant during sporogenesis, gametogenesis, and embryogenesis. While the molecular a...
متن کاملInfluences of clonality on plant sexual reproduction.
Flowering plants possess an unrivaled diversity of mechanisms for achieving sexual and asexual reproduction, often simultaneously. The commonest type of asexual reproduction is clonal growth (vegetative propagation) in which parental genotypes (genets) produce vegetative modules (ramets) that are capable of independent growth, reproduction, and often dispersal. Clonal growth leads to an expansi...
متن کاملSexual signaling on a cellular level: lessons from plant reproduction.
In this essay, I convey the results of some of our recent studies of reproduction in the model plant, Arabidopsis thaliana. Our work has been influenced by the investigations of a large and interactive community of researchers studying a variety of plant systems, including lily, tobacco, maize, and plants from the mustard family (for recent reviews, see Cheung et al., 2000; Dixit and Nasrallah,...
متن کاملPlant Sexual Reproduction : Aspects of Interaction , History and Regulation Michiel
Sexual reproduction in angiosperms is an interactive process involving the sporophyte, gametophytes, embryo and endosperm as well as the environment, aimed at achieving pollination, fertilization and dispersal. This interaction occurs via an interface with nutrients and signals outside the cell and even outside the plant. Sexual reproduction has a history. In water, algae have different types o...
متن کاملTemperature stress and plant sexual reproduction: uncovering the weakest links.
The reproductive (gametophytic) phase in flowering plants is often highly sensitive to hot or cold temperature stresses, with even a single hot day or cold night sometimes being fatal to reproductive success. This review describes studies of temperature stress on several crop plants, which suggest that pollen development and fertilization may often be the most sensitive reproductive stage. Tran...
