| 31. | There also exist PTOX cyanophages that contain copies of the gene for the plastid oxidase.
|
| 32. | Late into the constriction phase, dynamin proteins assemble around the outer plastid-dividing ring,
|
| 33. | Plastids have DNA sequences that indicate origin from the cyanobacteria ( blue-green algae ).
|
| 34. | In contrast, they have no effect on the plastids of the highly developed vascular plants.
|
| 35. | This is supporting the endosymbiotic theory and indicates an evolution of plastid division in land plants.
|
| 36. | As a result, many plastid and mitochondrial processes are driven by nuclear encoded gene products.
|
| 37. | The process of secondary endosymbiosis left its evolutionary signature within the unique topography of plastid membranes.
|
| 38. | All dinoflagellates contain red algal plastids or remnant ( nonphotosynthetic ) organelles of red algal origin.
|
| 39. | In some cases these plastids may be reduced in their metabolic and / or photosynthetic capacity.
|
| 40. | Amyloplasts are plastids, specifically leucoplasts.
