Chloroplast DNA (cpDNA), also known as plastid DNA (ptDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus.
Chloroplasts that are the product of secondary endosymbiosis may have additional membranes surrounding these three. [30] Inside the outer and inner chloroplast membranes is the chloroplast stroma, a semi-gel-like fluid [23] that makes up much of a chloroplast's volume, and in which the thylakoid system floats.
For example, chloroplasts in plants and green algae have lost all phycobilisomes, the light harvesting complexes found in cyanobacteria, red algae and glaucophytes, but instead contain stroma and grana thylakoids. The glaucocystophycean plastid—in contrast to chloroplasts and rhodoplasts—is still surrounded by the remains of the ...
Like mitochondria, chloroplasts have a double-membrane envelope, called the chloroplast envelope, but unlike mitochondria, chloroplasts also have internal membrane structures called thylakoids. Furthermore, one or two additional membranes may enclose chloroplasts in organisms that underwent secondary endosymbiosis , such as the euglenids and ...
Chlororespiration basics. Chlororespiration is a respiratory process that takes place within plants. Inside plant cells there is an organelle called the chloroplast which is surrounded by the thylakoid membrane.
Possible cladogram of chloroplast evolution [2] [3] Circles represent endosymbiotic events. For clarity, dinophyte tertiary endosymbioses and many nonphotosynthetic lineages have been omitted. a It is now established that Chromalveolata is paraphyletic to Rhizaria .
U.S. President-elect Donald Trump said "anything can happen" when asked about the chances of going to war with Iran during his next term in an interview with Time, coinciding with his being named ...
For example, 25 chloroplast genomes were sequenced for one molecular phylogenetic study. [1] The flowering plants are especially well represented in complete chloroplast genomes. As of January, 2017, all of their orders are represented except Commelinales, Picramniales, Huerteales, Escalloniales, Bruniales, and Paracryphiales.
