Adaptation of the Drosophila circadian clock to seasonal changes in temperature and photoperiod
No full textIn Drosophila melanogaster, splicing of an intron in the 3' untranslated region of the period (per) mRNA (herein referred to as dmpi8) is enhanced at cold temperatures, leading to more rapid daily increases in per transcript levels and earlier "evening" activity. We show that shortening the photoperiod (day-length) enhances daily fluctuations in the splicing of dmpi8 and advances its cycle, whereas the amplitude of the clock-regulated daytime decline in splicing increases as temperatures rise. Our results identify a novel non-photic role for NORPA in the temperature regulated repression of dmpi8 splicing.
In related work I found that two haplotypes (termed VT1.1 and VT1.2) in the per 3' UTR with six natural polymorphisms showed differential splicing efficiency in inbred flies, transgenic flies, and S2 cells. The VT1.1 haplotype leads to better dmpi8 splicing and earlier evening activity. Splicing assays in S2 cells also suggest that efficient dmpi8 splicing promotes per mRNA export. Our results suggest that splicing of dmpi8 plays a major role for Drosophila in adapting to local climates.
This dissertation also shows that light acutely stimulates the expression of tim at cold but not warm temperatures and that this is regulated at the transcriptional level. Cold-specific stimulation of tim RNA abundance requires CLK or CYC but not PER, TIM, CRY, or the canonical phototransduction pathway. The photoinduction of tim is temporally restricted to the daily rising phase in tim mRNA levels, likely ensuring that sunrise does not prematurely stimulate tim expression during unseasonably cold long days.
My work suggests a model whereby temperature and day-length are integrated to set the phase of the clock in a seasonably appropriate manner. Namely, during cold short days, stimulation of per dmpi8 splicing and photoinduction of tim mRNA transcription ensures that both per and tim transcripts accumulate more rapidly, leading to Drosophila exhibiting preferential activity during the warmer daytime hours despite the earlier onset of dusk. Conversely, during warm long days, the inefficient splicing of dmpi8 and lack of light stimulated tim transcription delay evening activity such that flies avoid the deleterious effects of the hot midday hours.Ph.D.Includes bibliographical references (p. 121-135)
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
