dc.description.abstract | Background: Knowledge about vitellogenesis in spiders is rudimentary. Therefore, the aim of study was to check
the vitellogenin (Vg) presence in various tissues of the female spider Parasteatoda tepidariorum, determine when
and where vitellogenesis starts and takes place, and the putative role of selected hormones in the vitellogenesis.
Results: Here we show two genes encoding Vg (PtVg4 and PtVg6) in the genome of the spider P. tepidariorum.
One gene PtVg4 and three subunits of Vg (250 kDa, 47 kDa and 30 kDa) are expressed in the midgut glands, ovaries
and hemolymph. Heterosynthesis of the Vg in the midgut glands and autosynthesis in the ovaries were observed.
Vitellogenesis begins in the last nymphal stage in the midgut glands (heterosynthesis). However, after sexual
maturity is reached, Vg is also synthesized in the ovaries (autosynthesis). Changes in the PtVg4 expression level and
in the Vg concentration after treatment with 20-hydroxyecdysone, a juvenile hormone analog (fenoxycarb) and an
antijuvenoid compound (precocene I) were observed. Therefore, we propose a hypothetical model for the hormonal
regulation of vitellogenesis in P. tepidariorum.
Conclusions: Our results are the first comprehensive study on spider vitellogenesis. In our opinion, this work will open
discussion on the evolutionary context of possible similarities in the hormonal control of vitellogenesis between
P. tepidariorum and other arthropods as well as their consequences. | pl_PL |
