Structural aspects of dormancy in quinoa (Chenopodium quinoa): Importance and possible action mechanisms of the seed coats [PDF]
, 2015 Two possible sources of resistance to pre-harvest sprouting were evaluated in quinoa. They showed dormancy at harvest and significant variations in dormancy level in response to environmental conditions experienced during seed development.

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

A Perspective on Secondary Seed Dormancy in Arabidopsis thaliana
Plants, 2020 Primary seed dormancy is the phenomenon whereby seeds newly shed by the mother plant are unable to germinate under otherwise favorable conditions for germination.

MECHANICS OF DORMANCY IN SEEDS
American Journal of Botany, 1916 Dormancy in plants is common in three organs, seeds, spores, and buds. In this paper I shall limit myself entirely to the discussion of dormancy in seeds for three reasons: far more critical and analytical work has been done on dormancy in seeds than upon the other two organs; obscure correlation effects do not play as prominent a part as in buds; and ...

Using automated sanding to homogeneously break seed dormancy in black locust (Robinia pseudoacacia L., Fabaceae) [PDF]
, 2017 peer reviewedPhysical dormancy of Robinia pseudoacacia seeds makes it a challenge for scientists and forest managers to obtain a homogeneous germination for larger seed samples. Water imbibition of the seeds can be achieved through manual piercing of the

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

ICE1 and ZOU determine the depth of primary seed dormancy in Arabidopsis independently of their role in endosperm development [PDF]
, 2018 Seed dormancy is a widespread and key adaptive trait that is essential for the establishment of soil seed banks and prevention of preharvest sprouting. Herein we demonstrate that the endosperm-expressed transcription factors ZHOUPI (ZOU) and INDUCER OF ...

Seed dormancy concepts in orchids: Dendrobium cruentum as a model species.
, 2022 Generally, orchids produce dust-like seeds in which endosperm reduction and embryo undifferentiation represent a derived state shared with species in about 11 other plant families.
