Control of developmental timing in Caenorhabditis elegans.
Studies of the nematode Caenorhabditis elegans have identified genetic and molecular mechanisms controlling temporal patterns of developmental events. Mutations in genes of the C. elegans heterochronic pathway cause altered temporal patterns of larval development, in which cells at certain larval stages execute cell division patterns or differentiation programs normally specific for other stage...
متن کاملDevelopmental robustness in the Caenorhabditis elegans embryo.
Developmental robustness is the ability of an embryo to develop normally despite many sources of variation, from differences in the environment to stochastic cell-to-cell differences in gene expression. The nematode Caenorhabditis elegans exhibits an additional level of robustness: Unlike most other animals, the embryonic pattern of cell divisions is nearly identical from animal to animal. The ...
متن کاملGenotype-specific developmental plasticity shapes the timing and robustness of reproductive capacity in Caenorhabditis elegans
The effects of environmental stress on developmental phenotypes allows us to observe the adaptive capacity of various genotypes. In single-genotype populations, this allows for observing the effects of standing variation on the process of developmental plasticity. Typically, such efforts do not allow us to distinguish the effect of genotype from the effects of environment. In the Nematode Caeno...
متن کاملThe TRIM-NHL Protein LIN-41 Controls the Onset of Developmental Plasticity in Caenorhabditis elegans
The mechanisms controlling cell fate determination and reprogramming are fundamental for development. A profound reprogramming, allowing the production of pluripotent cells in early embryos, takes place during the oocyte-to-embryo transition. To understand how the oocyte reprogramming potential is controlled, we sought Caenorhabditis elegans mutants in which embryonic transcription is initiated...
متن کاملThe evolution of plasticity of dauer larva developmental arrest in the nematode Caenorhabditis elegans
Organisms can end up in unfavourable conditions and to survive this they have evolved various strategies. Some organisms, including nematodes, survive unfavourable conditions by undergoing developmental arrest. The model nematode Caenorhabditis elegans has a developmental choice between two larval forms, and it chooses to develop into the arrested dauer larva form in unfavourable conditions (sp...
