Developmental Plasticity, Straight from the Worm’s Mouth
نویسندگان
چکیده
Developmental plasticity in response to environmental conditions (polyphenism) plays an important role in evolutionary theory. Analyzing the nematode taxon Pristionchus, Ragsdale et al. demonstrate that a single gene underlies the nematode's ability to develop distinct mouth forms in response to environmental changes.

Feeding plasticity in the nematode Pristionchus pacificus is influenced by sex and social context and is linked to developmental speed.
The increasing evidence for a role of developmental plasticity in evolution offers exciting prospects for testing interactions between ecological and developmental genetic processes. Recent advances with the model organism Pristionchus pacificus have provided inroads to a mechanistic understanding of a developmental plasticity. The developmental plasticity of P. pacificus comprises two disconti...
متن کاملA Developmental Switch Coupled to the Evolution of Plasticity Acts through a Sulfatase
Developmental plasticity has been suggested to facilitate phenotypic diversity, but the molecular mechanisms underlying this relationship are little understood. We analyzed a feeding dimorphism in Pristionchus nematodes whereby one of two alternative adult mouth forms is executed after an irreversible developmental decision. By integrating developmental genetics with functional tests in phenoty...
متن کاملChromatin remodelling and antisense-mediated up-regulation of the developmental switch gene eud-1 control predatory feeding plasticity
Phenotypic plasticity has been suggested to act through developmental switches, but little is known about associated molecular mechanisms. In the nematode Pristionchus pacificus, the sulfatase eud-1 was identified as part of a developmental switch controlling mouth-form plasticity governing a predatory versus bacteriovorous mouth-form decision. Here we show that mutations in the conserved histo...
متن کاملDevelopmental Effects of Melatonin on Synaptic Plasticity of Hippocampal CA1 Neurons in Visual Deprived Rats
Background & Aims: Change in visual experience impairs circadian rhythms. In this study, The effects of visual deprivation during critical period of brain development and melatonin intake on synaptic plasticity of hippocampal CA1 neurons were evaluated. Methods: This experimental study was done on male rats kept in standard 12 hour light/dark condition (L...
متن کاملDevelopmental effect of light deprivation on synaptic plasticity of rats' hippocampus: implications for melatonin
Objective(s): There are few reports have demonstrated the effect of a change-in-light experience on the structure and function of hippocampus. A change-in-light experience also affects the circadian pattern of melatonin secretion. This study aimed to investigate developmental effect of exogenous melatonin on synaptic plasticity of hippocampus of light deprived rats. Materials and Methods: The ...
