Research advances on embryonic diapause in mammals
Animal Reproduction Science, 2018Embryonic diapause occurs in over 130 species of mammals. In embryonic diapause, there is a reversible cessation phase in embryo development and subsequent reactivation and continuation of development with no adverse effects. This allows animals to prolong gestation and give birth to offspring at a more favorable time from a survival perspective ...

Embryonic diapause in vertebrates
Journal of Experimental Zoology, 1993AbstractEmbryonic diapause occurs in many species of vertebrates, but the physiological mechanisms which control this fascinating process are exceedingly different in the diverse groups which employ this reproductive strategy. In nonmammalian species and some bats, reduction in rate of embryonic development is temperature dependent, but this is not the

G protein-coupled receptor for diapause hormone, an inducer of Bombyx embryonic diapause
Biochemical and Biophysical Research Communications, 2006Bombyx diapause hormone was the first chemical substance identified as a maternal control factor that arrests offspring development. However, the molecular mechanisms by which the hormone transduces the signal to the oocyte that induces embryonic diapause immediately after mesoderm segmentation are not fully understood. Here, we describe a cDNA for a G

Eleven-month “Embryonic Diapause” Marsupial
Nature, 1966THE tammar, Protemnodon eugenii (Desm.), is included in the marsupial family Macropodidae in which the majority of species so far studied exhibit lactation-controlled delayed implantation1. Tyndale-Biscoe2 pointed out that, unlike eutherian mammals which have delayed implantation, the marsupial blastocyst does not implant as soon as development ...

Embryonic Diapause and Maternal Recognition of Pregnancy in Diapausing Mammals
2015The dynamic nature of early embryonic growth is at odds with the phenomenon of mammalian embryonic diapause, because embryos in diapause are in a state of suspended animation of varying duration. The signals that control embryonic diapause differ between species, but in all cases, it acts to synchronise reproduction with external factors to maximise ...

Breeding season and embryonic diapause in crabeater seals (Lobodon carcinophagus)
Reproduction, 2003Direct observation of 387 embryos in the early stages of development was combined with observations on breeding behaviour and reproductive biology obtained from the published literature, to estimate the timing of births, oestrus, ovulation and implantation, and to derive estimates of the duration of pregnancy, embryonic diapause and active gestation ...

Possible involvement of ecdysteroids in embryonic diapause of Locusta migratoria
Journal of Insect Physiology, 2002In the Ibaraki population (Japan) of Locusta migratoria, adult locusts produce diapause eggs under short-day (SD) conditions and non-diapause eggs under long-day (LD) conditions. The identity and titre of ecdysteroids in the ovaries and eggs from LD and SD adult females were investigated by RIA/HPLC.
