Evolution of Oleosin in Land Plants
Oleosins form a steric barrier surface on lipid droplets in cytoplasm, preventing them from contacting and coalescing with adjacent droplets. Oleosin genes have been detected in numerous plant species. However, the presence of oleosin genes in the most basally diverging lineage of land plants, liverworts, has not been reported previously. Thus we explored whether liverworts have an oleosin gene...
متن کاملEvolution of Primitive Land Plants: A Review
Our understanding of the evolution of primitive land plants is overviewed. Molecular phylogenetic data suggest that the suggested ancestor of the land plants is Charophyceae, although other ancestry is suggested based on different lines of evidence. Invasion to land environment during the mid-Ordovician or earlier should have been made possible by chemical compounds, ozone, flavonoid, cutin, sp...
متن کاملLand Plant Evolution: Listen to Your Elders
The genetic and molecular basis of the developmental programs underlying adaptive morphological changes is largely unknown. A new study reveals an ancient gene that has been instrumental for the generation of morphological diversity and adaptation in land plants.
متن کاملThe timescale of early land plant evolution
Establishing the timescale of early land plant evolution is essential for testing hypotheses on the coevolution of land plants and Earth's System. The sparseness of early land plant megafossils and stratigraphic controls on their distribution make the fossil record an unreliable guide, leaving only the molecular clock. However, the application of molecular clock methodology is challenged by the...
متن کاملThe evolution of land plant cilia.
Eukaryotic cilia/flagella are ancient organelles with motility and sensory functions. Cilia display significant ultrastructural conservation where present across the eukaryotic phylogeny; however, diversity in ciliary biology exists and the ability to produce cilia has been lost independently on a number of occasions. Land plants provide an excellent system for the investigation of cilia evolut...
