These findings provide a better understanding of the regulation mechanisms controlling chloroplast development and ribosome assembly in plant organelles.
Webb18 juni 2024 · Genes for many chloroplast ribosomal proteins, as well as proteins with auxiliary roles in ribosome biogenesis or functioning, reside in the nucleus. Here, we … Chloroplasts are one of many types of organelles in the plant cell. They are considered to have evolved from endosymbiotic cyanobacteria. Mitochondria are thought to have come from a similar endosymbiosis event, where an aerobic prokaryote was engulfed. This origin of chloroplasts was first … Visa mer A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, … Visa mer Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA (cpDNA) was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast … Visa mer Distribution in a plant Not all cells in a multicellular plant contain chloroplasts. All green parts of a plant contain chloroplasts—the chloroplasts, or more specifically, the chlorophyll in them are what make the photosynthetic parts of a plant green. The Visa mer Chloroplasts are a special type of a plant cell organelle called a plastid, though the two terms are sometimes used interchangeably. There are many other types of plastids, … Visa mer The first definitive description of a chloroplast (Chlorophyllkörnen, "grain of chlorophyll") was given by Hugo von Mohl in 1837 as discrete bodies within the green plant cell. In 1883, Andreas Franz Wilhelm Schimper would name these bodies as "chloroplastids" … Visa mer In land plants, chloroplasts are generally lens-shaped, 3–10 μm in diameter and 1–3 μm thick. Corn seedling chloroplasts are ≈20 µm in volume. Greater diversity in chloroplast shapes exists among the algae, which often contain a single chloroplast that can be shaped … Visa mer Guard cell chloroplasts Unlike most epidermal cells, the guard cells of plant stomata contain relatively well-developed … Visa mer
