Seasonal and developmental timing of flowering

The Plant Journal, 2010
SummaryThe coordination of the timing of flowering with seasonal and development cues is a critical life‐history trait that has been shaped by evolution to maximize reproductive success. Decades of studying many plant species have revealed several of the fascinating systems that plants have evolved to control flowering time: such as the perception of ...

Control of developmental timing in animals

Nature Reviews Genetics, 2001
The molecular mechanisms that time development are now being deciphered in various organisms, particularly in Caenorhabditis elegans. Key recent findings indicate that certain C. elegans timekeeping genes are conserved across phyla, and their developmental expression patterns indicate that a timing function might also be conserved.

Human encephalization and developmental timing

Journal of Human Evolution, 2005
Human evolution is frequently analyzed in the light of changes in developmental timing. Encephalization in particular has been frequently linked to the slow pace of development in Homo sapiens. The "brain allometry extension" theory postulates that the progressive extension of a conserved primate brain allometry into postnatal life was the basis for ...

Developmental aspects of timing behavior in children

Neurotoxicology and Teratology, 2004
This research examined the association of age, sex, and intelligence on the performance of a time production (temporal response differentiation, TRD) task. Variations of this task have been used extensively with both animals and humans to study factors that affect aspects of timing ability.

An analysis of developmental timing in Dictyostelium discoideum

Developmental Biology, 1983
A new method has been developed to assess the minimum complexity and relationships of those pathways (developmental timers) which time the consecutive stages of a developing system (Soll, 1983). This method has been applied to the morphogenetic program of Dictyostelium discoideum and has resulted in (1) a minimum estimate of the number of components ...

Nutrient Signaling and Developmental Timing of Maturation

2013
In animals, developmental timing of sexual maturation is tightly linked to nutrition and growth. Maturation only occurs once the juvenile has acquired sufficient nutrients and completed enough growth to produce a reproductively mature adult with a genetically predefined body size.

The Timing of Syllable Repetitions in Developmental Dyslexia

Journal of Speech, Language, and Hearing Research, 1990
The temporal organization of motor speech was examined in dyslexic dolescents and adults without overt speech difficulties, matched normal readers, and learning disabled adolescents without reading difficulties. Subjects were asked to repeat nonsense two- and three-syllable strings in time to each of four metronome speeds.

Developmental Timekeeping: Marking time with antisense

Current Biology, 1994
Post-transcriptional regulation of the heterochronic gene lin-14 by the binding of a natural antisense RNA controls the temporal pattern of larval development in the nematode Caenorhabditis elegans.

Times of Life and Timing in Developmental Psychology

Culture & Psychology, 2006
For the many aspects of psychological time, there are many approaches to understanding, including cultural theories, psychological studies, philosophical analyses and mathematical models. A useful approach is to assume that there are many kinds of psychological time in coexistence, and to distinguish their different cultural and meaning-based contexts,
