Poplar woody root proteome during the transition dormancy-active growth [PDF]

, 2013
Woody plants living in temperate climates finely regulate their growth and development in relation to seasonal changes; their transition from vegetative to dormancy phase represents an adaptation to their environment. Events occurring in the shoot during

Evolutionary trade-offs in dormancy phenology

eLife
Seasonal animal dormancy is widely interpreted as a physiological response for surviving energetic challenges during the harshest times of the year (the physiological constraint hypothesis).

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Extrato de alho melhora a superação da dormência de videiras ‘Niagara Rosada’em regiões subtropicais. [PDF]

, 2010
Nas regiões com invernos amenos, normalmente as exigências de frio para a quebra de dormência de gemas de videiras não são atendidas, e apenas os produtos altamente tóxicos CaCN2 e H2CN2 são recomendados na viticultura convencional para quebra de ...

Physiological Studies on Dormancy in Cape Tulip [PDF]

Australian Journal of Biological Sciences, 1969
A high proportion of cormils of the two· leaved species of the weed, Cape tulip, showed long-term dormancy, and e.xperiments showed that this dormancy is not due to a high level of endogenous growth inhibitors but is due to physical factors associated with the presence of intact cormil coats.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Carbon disulphide promotes sprouting of potato minitubers [PDF]

, 2010
We investigated the effects of postharvest application of carbon disulphide (CS2) in various concentrations (0, 15, 25, 35, 45 and 55 ml m-3) and with different exposure duration (24, 48, 72 and 96 h) on breaking of dormancy and sprouting of potato ...

Establishment of in vitro tissue cultures from Echinacea angustifolia D.C. adult plants for the production of phytochemical compounds [PDF]

, 2009
SUMMARY The establishment of in vitro cultures of Echinacea angustifolia D.C. was obtained directly from sections of flower stalks of adult plants. The shoot formation was obtained from this plantmaterial placed on a modified MS basal medium named CH ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

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

Physiological and biochemical changes in Pterogyne nitens tull. Seeds during the artificial aging process

Pesquisa Agropecuária Tropical, 2012
The accelerated aging test is usually used to evaluate seeds vigor and quality. This study aimed to investigate and establish relations among deterioration, physiological changes, and catalase enzyme activity, during the artificial aging process of ...
