Cell cycle genes are activated earlier than respiratory genes during release of grapevine buds from endodormancy
(Taylor & Francis, 2017)
Single-bud cuttings of Vitis vinifera L exposed to forced growing conditions were used to investigate the involvement of phytohormones, abscisic acid (ABA), auxin (Aux) and cytokinin (CK) in the release of buds from the ...
ABA biosynthesis genes are down regulated while auxin and cytokinin biosynthesis genes are up-regulated during the release of grapevine buds from endodormancy
Auxin–cytokinin (CK) interactions have been extensively studied in the control of bud outgrowth in herbaceous plants. However, in temperate woody plants where the meristem of dormant buds can be repressed by either exogenous ...
SIMILARITIES BETWEEN NATURAL AND CHEMICALLY INDUCED BUD-ENDODORMANCY RELEASE IN GRAPEVINE VITIS VINIFERA L.
(ELSEVIER SCIENCE BV, 2010)
Similarities between natural and chemically induced bud-endodormancy release in grapevine Vitis vinifera L.
(ELSEVIER SCIENCE BV, 2010-05-19)
Bud-break in grapevines (Vitis vinifera L) can be poor and uneven in locations that have warm winters with insufficient chilling. Growers in these regions use hydrogen cyanamide (HC), a dormancy-breaking compound, to ...
Is GABA-shunt functional in endodormant grapevine buds under respiratory stress?
It has been suggested that a respiratory stress is part of the mechanism through which the dormancy-breaking compounds, hydrogen cyanamide (HC) and sodium azide, induce the release of buds from the endodormancy (ED) ...
Alterations in the pattern of peroxidase isoenzymes and transient increases in its activity and in H2O2 levels take place during the dormancy cycle of grapevine buds: The effect of hydrogen cyanamide
Polymorphism of peroxidase (Px) and changes in its activity and in H 2O2 content were studied in buds of grapevine during dormancy. Three isoforms of Px were detected in bud-extracts, two basic and one acidic, however, the ...
Possible role of catalase in post-dormancy bud break in grapevines
(URBAN & FISCHER VERLAG, BRANCH OFFICE JENA, 2005-03)
Changes in the activity of catalase (Cat) and in the levels of H2O2 were followed throughout dormancy in buds of grapevines (Vitis vinifera L.). In grapevines grown in the Elqui valley in Chile, a region with warm-winters, ...
Hypoxia and hydrogen cyanamide induce bud-break and up-regulate hypoxic responsive genes (HRG) and VvFT in grapevine-buds
It has been reported that dormancy-breaking compound hydrogen cyanamide (HC) stimulates the fermentative pathway and inhibits respiration in grapevinebuds, suggesting in this way, that a respiratory stress must be ...
The dormancy-breaking stimuli “chilling, hypoxia and cyanamide exposure” up-regulate the expression of a-amylase genes in grapevine buds
It has been suggested that respiratory stress is involved in the mechanism underlying the dormancybreaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels ...
The dormancy-breaking stimuli "chilling, hypoxia and cyanamide exposure" up-regulate the expression of α-amylase genes in grapevine buds
It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels ...
