Any process that modulates the frequency, rate or extent of DNA replication.

Any process in which DNA and associated proteins are formed into a compact, orderly structure.

A sulfide oxidation process that proceeds via the reaction catalyzed by siroheme sulfite reductase.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

The chemical reactions and pathways resulting in the formation of amino acids containing sulfur, comprising cysteine, methionine and selenocysteine.

The pathways by which inorganic sulfate is processed and incorporated into sulfated compounds.

The chemical reactions and pathways involving the nonmetallic element sulfur or compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione.

A sulfide oxidation process that proceeds via the reaction catalyzed by siroheme sulfite reductase.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Any process in which plastidial DNA and associated proteins are formed into a compact, orderly structure.

Any process that modulates the frequency, rate or extent of DNA replication.

Any process in which DNA and associated proteins are formed into a compact, orderly structure.

The chemical reactions and pathways involving the nonmetallic element sulfur or compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cold stimulus, a temperature stimulus below the optimal temperature for that organism.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating an increase or decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.

The chemical reactions and pathways resulting in the formation of hydrogen sulfide, H2S.

The space enclosed by the double membrane of a chloroplast but excluding the thylakoid space. It contains DNA, ribosomes and some temporary products of photosynthesis.

The region of a chloroplast to which the DNA is confined.

The region of a chloroplast to which the DNA is confined.

A multisubunit iron flavoprotein, which in yeast is composed of 2 alpha and 2 beta subunits. Catalyzes the reduction of sulfite to sulfide.

The space enclosed by the double membrane of a chloroplast but excluding the thylakoid space. It contains DNA, ribosomes and some temporary products of photosynthesis.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A multisubunit iron flavoprotein, which in yeast is composed of 2 alpha and 2 beta subunits. Catalyzes the reduction of sulfite to sulfide.

A multisubunit iron flavoprotein, which in yeast is composed of 2 alpha and 2 beta subunits. Catalyzes the reduction of sulfite to sulfide.

A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.

Any member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid.

The double lipid bilayer enclosing the chloroplast and separating its contents from the rest of the cytoplasm; includes the intermembrane space.

Thin filamentous structure extending from the surface of all plastid types examined so far, including chloroplast, proplastid, etioplast, leucoplast, amyloplast, and chromoplast. In general, stromules are more abundant in tissues containing non-green plastids, and in cells containing smaller plastids. The primary function of stromules is still unresolved, although the presence of stromules markedly increases the plastid surface area, potentially increasing transport to and from the cytosol. Other functions of stromules, such as transfer of macromolecules between plastids and starch granule formation in cereal endosperm, may be restricted to particular tissues and cell types.

A dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The cell membranes and intracellular regions in a plant are connected through plasmodesmata, and plants may be described as having two major compartments: the living symplast and the non-living apoplast. The apoplast is external to the plasma membrane and includes cell walls, intercellular spaces and the lumen of dead structures such as xylem vessels. Water and solutes pass freely through it.
