Chlamydomonas is used as a model organism for molecular biology, especially studies of flagellar motility and chloroplast dynamics, biogenesis, and genetics. One of the many striking features of Chlamydomonas is that it contains ion channels ( channelrhodopsins ) that are directly activated by light.
Plants have a number of different means to attract pollinators including color, scent, heat, nectar glands, edible pollen and flower shape. Along with modifications involving the above structures two other conditions play a very important role in the sexual reproduction of flowering plants, the first is the timing of flowering and the other is ...
Mitotic recombination is a type of genetic recombination that may occur in somatic cells during their preparation for mitosis in both sexual and asexual organisms. In asexual organisms, the study of mitotic recombination is one way to understand genetic linkage because it is the only source of recombination within an individual. [1]
Combretum micranthum is a species of flowering plant in the family Combretaceae.It is a shrub known as kinkeliba in Guinea, Benin, Burkina Faso, Senegal, Mali and the Gambia across multiple regional dialects, where it is often found in tiger bush and on hills in West Africa.
The fungus was originally described by Jean Bulliard in 1788 as Boletus betulinus. [1] It was transferred to the genus Piptoporus by Petter Karsten in 1881. [2] Molecular phylogenetic studies suggested that the species was more closely related to Fomitopsis than to Piptoporus, [3] [4] and the fungus was reclassified to Fomitopsis in 2016.
Three types of cell division: binary fission (taking place in prokaryotes), mitosis and meiosis (taking place in eukaryotes).. When cells are ready to divide, because cell size is big enough or because they receive the appropriate stimulus, [20] they activate the mechanism to enter into the cell cycle, and they duplicate most organelles during S (synthesis) phase, including their centrosome.
They share many similarities with the higher plants, including the presence of asymmetrical flagellated cells, the breakdown of the nuclear envelope at mitosis, and the presence of phytochromes, flavonoids, and the chemical precursors to the cuticle. [4] The sole method of reproduction in Chlorella is asexual and azoosporic. The content of the ...
Many model systems have been developed to better understand interactions between plants and bacterial, fungal, oomycete, viral, and nematode pathogens. A. thaliana has been a powerful tool for the study of the subdiscipline of plant pathology , that is, the interaction between plants and disease-causing pathogens .
