Characterization of the Plasma Membrane H+-ATPase in the Liverwort Marchantia polymorpha1[W][OA]
The plasma membrane H-ATPase generates an electrochemical gradient of H across the plasma membrane that provides the driving force for solute transport and regulates pH homeostasis and membrane potential in plant cells. Recent studies have demonstrated that phosphorylation of the penultimate threonine in H-ATPase and subsequent binding of a 14-3-3 protein is the major common activation mechanis...
متن کاملThe Elegant Simplicity of the Liverwort Marchantia polymorpha.
Plants have evolved several ways to remain dormant until the time is right for growth. For example, seeds maintain dormancy through the antagonistic effects of the phytohormones abscisic acid (ABA) and gibberellic acid. Auxin (indole-3-acetic acid [IAA]), in turn, regulates ABA-induced seed dormancy through its interaction with the ABA signaling pathway (Liu et al., 2013). Dormancy is also cruc...
متن کاملMolecular evolution of mitochondrial introns in the liverwort Marchantia polymorpha
We here describe in detail the characterization and molecular evolution of group II introns in the mitochondrial genome of the liverwort Marchantia polymorpha. We find that 18 introns of the 25 group II introns can be assigned by their similarities to six clusters, indicating an intra-genomic propagation of one ancestral intron each into the respective clusters in the liverwort mitochondrial ge...
متن کاملCryopreservation of Gemmae from the Liverwort Marchantia polymorpha L.
The liverwort Marchantia polymorpha L. is one of the key model plants in evo-devo studies, and an increasing number of transgenic and mutant lines have been established. For reliable long-term preservation of M. polymorpha plants, spores have been used, but crossing is indispensable to obtain them. Gemmae, however, are vegetative clones and readily available in large numbers without crossing, t...
متن کاملActin-dependence of the chloroplast cold positioning response in the liverwort Marchantia polymorpha L.
The subcellular positioning of chloroplasts can be changed by alterations in the environment such as light and temperature. For example, in leaf mesophyll cells, chloroplasts localize along anticlinal cell walls under high-intensity light, and along periclinal cell walls under low-intensity light. These types of positioning responses are involved in photosynthetic optimization. In light-mediate...
