The lipid bilayer membrane of any thylakoid within a plastid.

The proteinaceous ground substance of plastids.

Unstacked thylakoids that connect the grana stacks through the stroma.

A photochemical system containing P700, the chlorophyll a dimer that functions as a primary electron donor. Functioning as a light-dependent plastocyanin-ferredoxin oxidoreductase, it transfers electrons from plastocyanin to ferredoxin.

An integral membrane complex containing P680, the chlorophyll a molecule that functions as a primary electron donor. In the light, functioning as a water-plastoquinone oxidoreductase, it transfers electrons from water to plastoquinone.

The precursor of other plastids.

Any process that increases the frequency, rate or extent of RNA-mediated transposition. RNA-mediated transposition is a type of transpositional recombination which occurs via an RNA intermediate.

Any process that increases the frequency, rate or extent of transposition. Transposition results in the movement of discrete segments of DNA between nonhomologous sites.

Any process that modulates the frequency, rate or extent of RNA-mediated transposition. RNA-mediated transposition is a type of transpositional recombination which occurs via an RNA intermediate.

Any process that modulates the frequency, rate or extent of transposition. Transposition results in the movement of discrete segments of DNA between nonhomologous sites.

Any process that decreases the frequency, rate or extent of transposition. Transposition results in the movement of discrete segments of DNA between nonhomologous sites.

Any process that decreases the rate of the directed movement of calcium ions into the cytosol of a cell. The cytosol is that part of the cytoplasm that does not contain membranous or particulate subcellular components.

Any process that stops, prevents or reduces the frequency, rate or extent of calcium ion transmembrane transport.

Any process that decreases the concentration of calcium ions in the cytosol.

Any process that increases the rate of the directed movement of calcium ions into the cytosol of a cell. The cytosol is that part of the cytoplasm that does not contain membranous or particulate subcellular components.

Any process that activates or increases the frequency, rate or extent of calcium ion transmembrane transport.

Any process that increases the concentration of calcium ions in the cytosol.

Any process that decreases the frequency, rate or extent of RNA-mediated transposition. RNA-mediated transposition is a type of transpositional recombination which occurs via an RNA intermediate.

A three dimensional regular lattice found in etioplasts. It is composed of a continuous system of tubules but when exposed to light the symmetrical arrangement is rapidly lost as tubules become pinched off into two dimensional sections of lattice. These for perforated sheets of membrane that move apart, extend and increase, finally establishing the typical granal and intergranal lamellae of the mature chloroplast.
