Plant 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 کاملGametophyte interaction and sexual reproduction: how plants make a zygote.
The evolutionary success of higher plants relies on a very short gametophytic phase, which underlies the sexual reproduction cycle. Sexual plant reproduction takes place in special organs of the flower: pollen, the male gametophyte, is released from the anthers and then adheres, grows and interacts along various tissues of the female organs, collectively known as the pistil. Finally, it fertili...
متن کاملSexual reproduction in octocorals
For octocorals, sexual reproductive processes are fundamental to maintaining populations and influencing macroevolutionary processes. While ecological data on octocorals have lagged behind their scleractinian counterparts, the proliferation of reproductive studies in recent years now enables comparisons between these important anthozoan taxa. Here we review the systematic and biogeographic patt...
متن کاملSexual reproduction in Aspergillus flavus.
Aspergillus flavus is the major producer of carcinogenic aflatoxins in crops worldwide and is also an important opportunistic human pathogen in aspergillosis. The sexual state of this heterothallic fungus is described from crosses between strains of the opposite mating type. Sexual reproduction occurred between sexually compatible strains belonging to different vegetative compatibility groups. ...
متن کاملEffects of Sexual Reproduction
Example 5.5: Near-critical binary splitting. The theorem applies to binary splitting where the probability of division is p(z) = 1/2+1/(2z), and q(z) = 1− p(z) is the probability of no children, if population size is z. Thus, m(z) = 1 + 1/z and the process is supercritical, but approaches criticality as z increases. The probability generating function of the offspring number is fz(s) = q(z) + p...
