Light-dependent transcriptional events during resting egg hatching of the rotifer Brachionus manjavacas

Light-dependent transcriptional events during resting egg

26 27 Rotifer resting eggs often have to endure harsh environmental conditions during the diapause phase. 28 They are stimulated by light to hatch. In order to study the hatching mechanism, we observed 29 resting eggs and measured their transcriptional expression under different light exposure periods 30 (total darkness, and after 30 min, and 4h light). By using differential-display reverse tra...

Monogonont Rotifer, Brachionus calyciflorus, Possesses Exceptionally Large, Fragmented Mitogenome

In contrast to the highly conserved mitogenomic structure and organisation in most animals (including rotifers), the two previously sequenced monogonont rotifer mitogenomes were fragmented into two chromosomes similar in size, each of which possessed one major non-coding region (mNCR) of about 4-5 Kbp. To further explore this phenomenon, we have sequenced and analysed the mitogenome of one of t...

Moderately lower temperatures greatly extend the lifespan of Brachionus manjavacas (Rotifera): Thermodynamics or gene regulation?

Environmental temperature greatly affects lifespan in a wide variety of animals, but the exact mechanisms underlying this effect are still largely unknown. A moderate temperature decrease from 22°C to 16°C extends the lifespan of the monogonont rotifer Brachionus manjavacas by up to 163%. Thermodynamic effects on metabolism contribute to this increase in longevity, but are not the only cause. W...

Joint inhibition of TOR and JNK pathways interacts to extend the lifespan of Brachionus manjavacas (Rotifera)

The TOR kinase pathway is central in modulating aging in a variety of animal models. The target of rapamycin (TOR) integrates a complex network of signals from growth conditions, nutrient availability, energy status, and physiological stresses and matches an organism's growth rate to the resource environment. Important remaining problems are the identification of the pathways that interact with...
