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
(Springer, 2017)
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 ...
Differences in respiration between dormant and non-dormant buds suggest the involvement of ABA in the development of endodormancy in grapevines
(Elsevier, 2016)
Grapevine buds (Vitis vinifera L) enter endodormancy (ED) after perceiving the short-day (SD) photoperiod signal and undergo metabolic changes that allow them to survive the winter temperatures. In the present study, we ...
Photoperiod modifies the diurnal expression profile of VvPHYA and VvPHYB transcripts in field-grown grapevine leaves
(2009)
Despite the crucial role that phytochromes (Phys) play in light perception and in the entrainment of the circadian clock to local time, the photoperiodic regulation of PHYA and PHYB gene expression has been poorly studied, ...
Relationship between bud cold hardiness and budbreak in two vitis vinifera L cultivars, chardonnay and thompson seedless
(Springer, 2021)
The lack of winter cold is a severe limitation for the cultivation of grapevines (Vitis vinifera L) in areas with warm winter climates. This phenomenon is currently becoming quite important due to global warming, which ...
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 ...
Sprouting of paradormant and endodormant grapevine buds under conditions of forced growth: similarities and differences
(Springer Verlag, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Main conclusion: Bud-break assays under forced growth conditions suggest that a drop in ABA content and an increase in sugars are common features in the sprouting ...
ABA promotes starch synthesis and storage metabolism in dormant grapevine buds
(Elsevier GmbH, 2019)
© 2019 Elsevier GmbH In grapevine (Vitis vinifera L.) buds, the short day (SD)-photoperiod induces endodormancy and increases the level of ABA and the expression of ABA key biosynthesis genes, which suggests that ABA could ...
Hydrogen peroxide increases during endodormancy and decreases during budbreak in grapevine (Vitis vinifera L.) buds
(MDPI, 2021)
Changes in the level of hydrogen peroxide (H2O2) is a good indicator to monitor fluctuations in cellular metabolism and in the stress responses. In this study, the changes in H2O2 content during bud endodormancy (ED) and ...
Is GABA-shunt functional in endodormant grapevine buds under respiratory stress?
(Springer, 2013)
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) ...
