Molecular Regulators of Embryonic Diapause and Cancer Diapause-like State

open access: yesCells, 2022
Embryonic diapause is an enigmatic state of dormancy that interrupts the normally tight connection between developmental stages and time. This reproductive strategy and state of suspended development occurs in mice, bears, roe deer, and over 130 other ...

Predicting the potential geographical distribution of the harlequin ladybird, Harmonia axyridis, using the CLIMEX model - BioControl [PDF]

open access: yes, 2008
Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) is a ladybird beetle native to temperate and subtropical parts of Asia. Since 1916 populations of this species have been introduced throughout the world, either deliberately, or by accident ...

Steroid hormone ecdysone deficiency stimulates preparation for photoperiodic reproductive diapause.

open access: yesPLoS Genetics, 2021
Diapause, a programmed developmental arrest primarily induced by seasonal environmental changes, is very common in the animal kingdom, and found in vertebrates and invertebrates alike.

Summer Diapause of the Clover Leaf Weevil, \u3ci\u3eHypera Punctata,\u3c/i\u3e and Lesser Clover Leaf Weevil, \u3ci\u3eHypera Nigrirostris,\u3c/i\u3e in Wisconsin [PDF]

open access: yes, 2017
Low respiration rates, immobility, lack of feeding, and undeveloped reproductive systems confirmed a summer diapause in the overwintered and current-year adults of the clover leaf weevil, Hypera punctata, and lesser clover leaf weevil, Hypera ...

Cell cycle dynamics during diapause entry and exit in an annual killifish revealed by FUCCI technology

open access: yesEvoDevo, 2019
Background Annual killifishes are adapted to surviving and reproducing over alternating dry and wet seasons. During the dry season, all adults die and desiccation-resistant embryos remain encased in dry mud for months or years in a state of diapause ...

Life Cycles of \u3ci\u3eLeuctra Duplicata\u3c/i\u3e and \u3ci\u3eOstrocerca Prolongata\u3c/i\u3e in an Intermittent Streamlet in Quebec (Plecoptera: Leuctridae and Nemouridae) [PDF]

open access: yes, 2017
Large populations of Ostrocerca prolongata and Leuctra duplicata developed in a small intermittent stream in the foothills of the Laurentian Highlands of Quebec. Both species were univoltine in 1974-1975.

Transcriptome Characterization Analysis of Bactrocera minax and New Insights into Its Pupal Diapause Development with Gene Expression Analysis

open access: yesInternational Journal on Biological Sciences, 2014
Bactrocera minax is a major citrus pest distributed in China, Bhutan and India. The long pupal diapause duration of this fly is a major bottleneck for artificial rearing and underlying mechanisms remain unknown. Genetic information on B.

Uterine fluid proteome changes during diapause and resumption of embryo development in roe deer (Capreolus capreolus)

open access: yesReproduction, 2019
The uterine microenvironment during pre-implantation presents a pro-survival milieu and is essential for embryo elongation in ruminants. The European roe deer (Careolus capreolus) pre-implantation embryo development is characterised by a 4-month period ...

Metabolomics Reveals Changes in Metabolite Profiles among Pre-Diapause, Diapause and Post-Diapause Larvae of Sitodiplosis mosellana (Diptera: Cecidomyiidae)

open access: yesInsects, 2022
Sitodiplosis mosellana, a notorious pest of wheat worldwide, copes with temperature extremes during harsh summers and winters by entering obligatory diapause as larvae. However, the metabolic adaptive mechanism underlying this process is largely unknown.
