A common molecular regulatory pathway that involves PHYA, PHYB and floral integrator genes CONSTANS (CO), FLOWERING LOCUS T (FT) and SUPRESSOR OF OVEREXPRESSION OF CO1 (SOC1) has been suggested to participate in the ...

Endodormancy (ED) and cold hardiness (CH) are two strategies utilized by grapevine (Vitis vinifera L.) buds to survive unfavorable winter conditions. Each phenomenon is triggered by different environmental cues—ED by ...

Main conclusion In grapevines, the increased expression of VvFT, genes involved in the photoperiodic control of seasonal growth (VvAP1, VvAIL2) and cell cycle genes (VvCDKA, VvCDKB2, VvCYCA1, VvCYCB, VvCYCD3.2) in the shoot ...

The production of temperate fruit trees in mild climates is dependent on the continuous criation of new cultivars with reduced chilling requirements and reliable methods to estimate them. Thus, it is necessary to study ...

The peach tree is a perennial species of economic importance in Brazil, however, not all cultivars are adapted to Brazilian growing conditions. The cultivars better adapt to the subtropical climate are those with low ...

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 ...

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 ...

A dynamic thermal time model (DTTM) has been developed to predict cold-hardiness in dormant grapevine buds, which uses daily mean temperatures as the only input variable. However, it has been recently reported that ...

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, ...
