| molecular function |
|---|
| | GO:0016168 | | chlorophyll binding | | Interacting selectively and non-covalently with chlorophyll; any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment. |
| | GO:0051738 | | xanthophyll binding | | Interacting selectively and non-covalently with xanthophylls, any of several neutral yellow to orange carotenoid pigments containing oxygen. |
| biological process |
|---|
| | GO:0010196 | | nonphotochemical quenching | | The process by which excess light energy absorbed by chlorophyll and not used to drive photosynthesis is emitted as heat. This process helps maintain the balance between dissipation and utilization of light energy to minimize generation of oxidizing molecules, thereby protecting the plant against photo-oxidative damage. |
| | GO:0015979 | | photosynthesis | | The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide (CO2) using energy obtained from light rather than from the oxidation of chemical compounds. |
| | GO:0080167 | | response to karrikin | | 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 karrikin stimulus. Karrikins are signaling molecules in smoke from burning vegetation that trigger seed germination for many angiosperms (flowering plants). |
| | GO:0010027 | | thylakoid membrane organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the thylakoid membrane. |
| cellular component |
|---|
| | GO:0009517 | | PSII associated light-harvesting complex II | | Protein-pigment complex associated with photosystem II. |
| | GO:0009507 | | chloroplast | | A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma. |
| | GO:0009534 | | chloroplast thylakoid | | Sac-like membranous structures (cisternae) in a chloroplast combined into stacks (grana) and present singly in the stroma (stroma thylakoids or frets) as interconnections between grana. An example of this component is found in Arabidopsis thaliana. |
| | GO:0009535 | | chloroplast thylakoid membrane | | The pigmented membrane of a chloroplast thylakoid. An example of this component is found in Arabidopsis thaliana. |
| | GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0009523 | | photosystem II | | A photosystem that contains a pheophytin-quinone reaction center with associated accessory pigments and electron carriers. In cyanobacteria and chloroplasts, in the presence of light, PSII functions as a water-plastoquinone oxidoreductase, transferring electrons from water to plastoquinone, whereas other photosynthetic bacteria carry out anoxygenic photosynthesis and oxidize other compounds to re-reduce the photoreaction center. |
| | GO:0009536 | | plastid | | 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. |
| | GO:0009579 | | thylakoid | | A membranous cellular structure that bears the photosynthetic pigments in plants, algae, and cyanobacteria. In cyanobacteria thylakoids are of various shapes and are attached to, or continuous with, the plasma membrane. In eukaryotes they are flattened, membrane-bounded disk-like structures located in the chloroplasts; in the chloroplasts of higher plants the thylakoids form dense stacks called grana. Isolated thylakoid preparations can carry out photosynthetic electron transport and the associated phosphorylation. |
