thylakoid light-harvesting complex
|
GO_0009503 |
[A thylakoid membrane complex of chlorophylls a and b together with chlorophyll a-b binding proteins. In addition, LHCs contain a number of other proteins, the function of which is speculative, together with accessory pigments. The LHCs capture and transfer energy to photosystems I and II. An example of this is found in Arabidopsis thaliana.] |
|
cell plate
|
GO_0009504 |
[The nascent cell membrane and cell wall structure that forms between two daughter nuclei near the center of a dividing plant cell. It develops at the equatorial region of the phragmoplast. It grows outwards to join with the lateral walls and form two daughter cells.] |
|
chromoplast
|
GO_0009509 |
[A plastid containing pigments other than chlorophyll, usually yellow and orange carotenoid pigments.] |
|
chloroplast
|
GO_0009507 |
[A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.] |
|
plastid chromosome
|
GO_0009508 |
[A circular DNA molecule containing plastid encoded genes.] |
|
chromosome
|
GO_0005694 |
[A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information.] |
|
transmitting tissue development
|
GO_0010500 |
[The process whose specific outcome is the progression of the transmitting tract over time, from its formation to the mature structure. The transmitting tissue is the tissue in the style of a carpel through which the pollen tube grows; it connects the stigma and the inside of ovary.] |
|
gynoecium development
|
GO_0048467 |
[The process whose specific outcome is the progression of the gynoecium over time, from its formation to the mature structure. The gynoecium is the collective name for the carpels of a flower.] |
|
cytochrome b6f complex
|
GO_0009512 |
[Complex that transfers electrons from reduced plastoquinone to oxidized plastocyanin and translocates protons from the stroma to the lumen. The complex contains a core structure of three catalytic subunits: cytochrome b, the Rieske iron sulfur protein (ISP), and cytochrome f, which are arranged in an integral membrane-bound dimeric complex; additional subunits are present, and vary among different species.] |
|
cytochrome complex
|
GO_0070069 |
[A protein complex in which at least one of the proteins is a cytochrome, i.e. a heme-containing protein involved in catalysis of redox reactions.] |
|
etioplast
|
GO_0009513 |
[A plastid arrested in the development of chloroplasts from proplastids due to absence of light or low light conditions.] |
|
plasmodesmatal desmotubule
|
GO_0009510 |
[A tightly wound cylinder of membrane that is located within the plasmodesmal pore and runs the length of the plasmodesma. The desmotubule likely provides a rigid stability to plasmodesmata and confers a fixed diameter and pore size to the plasmodesmal canal, and is linked to the endoplasmic reticulum in each of the adjacent cell.] |
|
plasmodesmatal endoplasmic reticulum
|
GO_0009511 |
[Endoplasmic reticulum found in plasmodesmata, junctions connecting the cytoplasm of adjacent plant cells.] |
|
leucoplast
|
GO_0009516 |
[A colorless plastid involved in the synthesis of monoterpenes.] |
|
PSII associated light-harvesting complex II
|
GO_0009517 |
[Protein-pigment complex associated with photosystem II.] |
|
glyoxysome
|
GO_0009514 |
[A specialized form of peroxisome that contains the enzymes of the glyoxylate pathway. The glyoxysome is found in some plant cells, notably the cells of germinating seeds.] |
|
granal stacked thylakoid
|
GO_0009515 |
[Appressed thylakoid membranes that are part of a granum (stacked regions). A characteristic of these appressed regions is the preferential localization of photosystem II.] |
|
chloroplast thylakoid
|
GO_0009534 |
[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.] |
|
middle lamella
|
GO_0009519 |
[Layer of intercellular material, chiefly pectic substances, cementing together the primary walls of contiguous cells.] |
|
extracellular matrix
|
GO_0031012 |
[A structure lying external to one or more cells, which provides structural support, biochemical or biomechanical cues for cells or tissues.] |
