Flavonoids as developmental regulators
Current Opinion in Plant Biology, 2005Flavonoids, usually regarded as dispensable phytochemicals derived from plant secondary metabolism, play important roles in the biology of plants by affecting several developmental processes. Bioactive flavonoids also signal to microbes, serve as allelochemicals and are important nutraceuticals in the animal diet.

Developmental regulation of oligosialylation in zebrafish
Glycoconjugate Journal, 2008Zebrafish appears as a relevant model for the functional study of glycoconjugates along vertebrate's development. Indeed, as a prelude to such studies, we have previously identified a vast array of potentially stage-specific glycoconjugates, which structures are reminiscent of glycosylation pathways common to all vertebrates.

Developmental regulation of the cell cycle
Current Opinion in Genetics & Development, 1992The control of metazoan cell proliferation, a problem long the domain of cell culture studies, is now being examined in developing animals. Surprisingly, developmental regulation is mediated at a variety of cell-cycle stages. Highly conserved cell-cycle control mechanisms provide a focus for studying the regulatory processes involved.

Developmental regulators in Aspergillus fumigatus
Journal of Microbiology, 2016The filamentous fungus Aspergillus fumigatus is the most prevalent airborne fungal pathogen causing severe and usually fatal invasive aspergillosis in immunocompromised patients. This fungus produces a large number of small hydrophobic asexual spores called conidia as the primary means of reproduction, cell survival, propagation, and infectivity.

Developmental regulation of TCR efficiency
European Journal of Immunology, 2000Unresponsiveness of mature T cells to the same self-peptide/self-MHC molecule complexes with which thymocytes have reacted during positive selection results from an increase of activation thresholds during maturation. The molecular events accounting for this increase are still unknown.

Developmental regulation of erythropoietin and erythropoiesis
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1997It is well established that erythropoiesis occurs first in the yolk sac, then in the liver, subsequently moving to the bone marrow and, in rodents, the spleen during development. The origin of the erythropoietic precursors and some factors suggested to be important for the changing location of erythropoiesis are discussed in this review. Until recently,

Developmental regulation of somatic imprints
Differentiation, 2011Genomic imprinting is an epigenetic phenomenon guiding the allele-specific marking of parental alleles. Genes regulated by imprinting are only or preferentially expressed from a single allele during development and in the adult, and the transcriptional activity of each allele is dictated by its parental origin.

Regulation by proteolysis: Developmental switches
Current Opinion in Microbiology, 1999The energy-dependent proteases originally defined in Escherichia coli have proven to have particularly important roles in bacterial developmental systems, including sporulation in Bacillus subtilis and cell cycle in Caulobacter. Degradation of key regulatory proteins participates, with regulation of synthesis and activity of the regulators, to ensure ...

Developmental regulation of microbial biofilms
Current Opinion in Biotechnology, 2002Sophisticated molecular and microscopic methods used to study biofilm formation are rapidly broadening our understanding of surface-attached microbial communities in a wide variety of organisms. Regulatory mechanisms involved in the attachment and subsequent development of mature biofilms are being elucidated.

The origins of developmental gene regulation
Evolution & Development, 2017SUMMARYThe leap from simple unicellularity to complex multicellularity remains one of life's major enigmas. The origins of metazoan developmental gene regulatory mechanisms are sought by analyzing gene regulation in extant eumetazoans, sponges, and unicellular organisms.
