Organelle Inheritance
The need to inherit those membranes that arise from the ER is much less clear. As an example, the integral *Imperial Cancer Research Fund Cell Biology Laboratory membrane proteins and lipids of the Golgi apparatus are derived entirely from the ER. If a daughter did not 44 Lincoln's Inn Fields London WC2A 3PX inherit a copy of the Golgi apparatus, it should be able to synthesize one de novo. Sev...
متن کاملUniparental inheritance of organelle genes
the remarkable and varied molecular and cellular mechanisms that produce these patterns. I will also consider the evolutionary consequences of uniparental inheritance and some of the proposed evolutionary explanations for this remarkable difference between the inheritance of organelle and nuclear genes. Patterns and mechanisms of uniparental inheritance vary widely Correns studied the four-o'cl...
متن کاملTransgene inheritance in plants.
The patterns of transgene inheritance in plants and the possible explanations for non-Mendelian transmission are reviewed. The non-Mendelian inheritance of a transgene has been recorded with a frequency between 10% and 50% in transgenic plants produced either by Agrobacterium-mediated transformation or through particle bombardment. Different effects such as deletion, duplication, rearrangement,...
متن کاملOrganelle biogenesis and positioning in plants.
The biogenesis and positioning of organelles involves complex interacting processes and precise control. Progress in our understanding is being made rapidly as advances in analysing the nuclear and organellar genome and proteome combine with developments in live-cell microscopy and manipulation at the subcellular level. This paper introduces the collected papers resulting from Organelle Biogene...
متن کاملMitochondrial membrane potential: a trait involved in organelle inheritance?
Which mitochondria are inherited across generations? Are transmitted mitochondria functionally silenced to preserve the integrity of their genetic information, or rather are those mitochondria with the highest levels of function (as indicated by membrane potential Δψm) preferentially transmitted? Based on observations of the unusual system of doubly uniparental inheritance of mitochondria and o...
