Effect of day-length shortening on gene expression on pea aphid heads

(Submitter supplied) Seasonal photoperiodism is responsable in aphid for the switch from asexual to sexual reproduction. In order to identify genes regulating the photoperiodic response, a cDNA microarray from the pea aphid was used to compare RNA populations from short- and long-day reared aphids. Analyses revealed that 64 different transcripts were significantly regulated, with a strong biological signature for cuticular proteins and proteins involved in cellular signalling or signal transduction. more...

Transcriptomic and proteomic analyses of seasonal photoperiodism in the pea aphid

(Submitter supplied) Aphid adaptation to harsh winter conditions is illustrated by an alternation of their reproductive mode. Aphids detect photoperiod shortening by sensing the length of the night and switch from viviparous parthenogenesis in spring and summer, to oviparous sexual reproduction in autumn. The photoperiodic signal is transduced from the head to the reproductive tract to change the fate of the future oocytes from mitotic diploid embryogenesis to haploid formation of gametes. more...

Global gene expression during the photoinduction process.

(Submitter supplied) The molecular mechanism of photoperiodic time measurement remains unknown in animals. Japanese quail is an excellent model for studying these phenomena because of their rapid and dramatic response to photoperiod. When quail are transferred from short to long day conditions, increase in plasma gonadotrophin (luteinising hormone: LH) can be observed by the end of the first long day and this phenomenon is called “first day release model”. more...

Comparative genomic hybridization between chicken and Japanese quail

(Submitter supplied) Since Japanese quail and chicken belong to the same order Galliforms, DNA sequence of both species are highly conserved and proved to be applicable for various analyses each other. Quail are commonly used to address physiological questions for reasons of economy. To test whether chicken microarrays are useful to quail samples, we compared hybridization signals of chicken and quail genomic DNA on Affymetrix chicken genome array. more...

Arabidopsis thaliana gene expression changes upon treatment with green peach aphid saliva

(Submitter supplied) Myzus persicae (green peach aphid) feeding on Arabidopsis thaliana induces a defense response, quantified as reduced aphid progeny production, in infested leaves but not in other parts of the plant. Similarly, infiltration of aphid saliva into Arabidopsis leaves causes only a local increase in aphid resistance. Further characterization of the defense-eliciting salivary components indicates that Arabidopsis recognizes a proteinaceous elicitor with a size between 3 to 10 kD. more...

Identification of Differential Gene Expression During Transition of Bovine Corpus Luteum from Early To Mid–Phase.

(Submitter supplied) Prostaglandin F2 alpha (PGF2alpha) brings about regression of the bovine corpus luteum (CL). This luteolytic property of PGF2alpha is used in the beef and dairy cattle to synchronize estrus. A limitation of this protocol is an insensitivity of the early CL to luteolytic actions of PGF2alpha. The mechanisms underlying luteal sensitivity (LS) are poorly understood. The early CL has maximum number of PGF2alpha receptors; therefore differences in signaling events might be responsible for LS. more...

Genome-wide expression analysis of the mouse pars tuberalis (PT) under chronic short-day and long-day conditions

(Submitter supplied) Living organisms detect seasonal changes in day length (photoperiod), and alter their physiological functions accordingly, to fit seasonal environmental changes. This photoperiodic system is implicated in seasonal affective disorders and the season-associated symptoms observed in bipolar disease and schizophrenia. Thyroid-stimulating hormone beta subunit (Tshb), induced in the pars tuberalis (PT), plays a key role in the pathway that regulates animal photoperiodism. more...

Expression data from brain tissue of Rattus norvegicus treated with D-Serine

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

Expression data for reproductive development in rice

(Submitter supplied) Plants initially undergo a period of vegetative development, in which it produces leaves from shoot apical meristem (SAM) and roots from the root apical meristem. Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. more...

Comparative gene expression in the limbus of the vervet monkey

(Submitter supplied) The limbus is a unique anatomic structure that is highly innervated and vascularized yet sets the boundary for the avascularized cornea. The corneal epithelial stem cells are believed to reside at the limbus. The intrinsic and external molecular signals that modulate the differentiation and proliferation of the limbal stems cells are still largely unidentified because of a lack of known specific markers. more...

Common genome-wide patterns of transcript accumulation underlying the wing polyphenism and polymorphism in the pea aphid

(Submitter supplied) The pea aphid, Acyrthosiphon pisum, exhibits several environmentally cued polyphenisms, in which discrete, alternative phenotypes are produced. At low density parthenogenetic females produce unwinged female progeny, but at high density females produce progeny that develop with wings. These alternative phenotypes represent a solution to the competing demands of dispersal and reproduction. Males also develop as either winged or unwinged, but these alternatives are determined by a genetic polymorphism. more...

Gene expression in Drosophila montana
