Characterization of Transcriptional and Post-transcriptional Regulation of lin-42/Period During Post-embryonic Development of C. elegans
… However, regulation of period function in developmental pathways has not been characterized and appears to be different from its regulation and function in circadian pathways. lin-42 is the Caenorhabditis elegans ortholog of period and has both circadian and developmental timing functions. …

Bionomia e etologia do Mocis latipes (Guenee, 1852) (Lepidoptera-Noctuidae)
Data are given on the post-embryonic development under experimental conditions, of Mocis latipes (Guenée, 1852) ,a highly polyphagous species, with marked preference for Gramineas. Data are also given on its ethology.

Changes in gall bladder bile throughout development in Rana catesbeiana
… of the following throughout the course of post-embryonic development: the change in GI tract length and weight; the relative surfactant activity of the bile; the change in major bile pigments. The most rapid and profound morphological and physiological transitions occur during the period of …

Nutritional Control of L1 Arrest and Recovery in Caenorhabditis elegans by Insulin-like Peptides and Signaling
<p>Animals must coordinate development with fluctuating nutrient availability. Nutrient availability governs post-embryonic development in Caenorhabditis elegans: larvae that hatch in the absence of food do not initiate post-embryonic development but enter "L1 arrest" (or "L1 diapause") and can …

Analysing The Effects Of Loss Of Sin3 In Drosophila Melanogaster
… we show that SIN3 is not only required for embryonic viability but also for post-embryonic development. Genetic analysis suggests that the different isoforms of SIN3 may regulate unique sets of genes during development. The developmental lethality occurring due to ubiquitous knock down of …

Mechanisms of axial polarity modification during postembryonic development of the basal bilaterian Convolutriloba macropyga
… of asexual reproduction that involve dramatic postembryonic modification of their anterior-posterior (AP) axis. The acoel species <em>Convolutriloba macropyga</em> reproduces through a reversed polarity budding process in which offspring develop from two posterior budding sites with a complete …

Postembryonic Polarity Modification in the Acoel Convolutriloba longifissura
… mechanisms of L-R polarity modification during postembryonic development. Regeneration experiments have elucidated the temporal dynamics of midline re-specification, suggesting that parallel L-R axes replace the pre-existing midline prior to longitudinal fission. We have characterized the …

Appendage development and early Distal-less regulation in arthropods: A study of the chelicerate Tetranychus urticae (Acarida)
A major goal of evolutionary developmental biology is to explore mechanisms and events underlying evolution of the myriad body plan morphologies expressed both genetically and phenotypically within the animal kingdom. Arthropods exhibit an astounding array of morphological diversity both within and …

Elucidation of the Role of miR-184 in the Development and Maintenance of the Drosophila Melanogaster Nervous System
… other aspects of gene expression, by acting as post-transcriptional repressors of their messengerRNA (mRNA) targets. miR-184 is a highly conserved miRNA gene expressed in the Drosophila nervous system throughout development; and has been shown to target key regulators of differentiation, …

DRE-1/FBXO11, a Conserved F Box Protein, Regulates Apoptosis in C. elegans and is Mutated in Human Lymphoma
<p>In the course of metazoan embryonic and post-embryonic development, more cells are generated than exist in the mature organism, and these cells are deleted by the process of programmed cell death. In addition, cells can be pushed toward death when they accumulate genetic errors, are …

Unraveling The Molecular Mechanisms Of Insect Diversity
… merger between the fields of evolutionary and developmental biology ("evo-devo") have provided several examples illustrating that this extraordinary diversification may be due to evolved variation(s) in the developmental networks that control the formation of these structures. In addition, the …
