Oxidative stress homeostasis in grapevine (Vitis vinifera L.)
TL;DR: This review will focus on antioxidant metabolites, antioxidant enzymes, transcriptional regulation and cross-talk with hormones prompted by abiotic stress conditions, and three situations that require specific homeostasis balance: biotic stress, the oxidative burst in berries at veraison and in vitro systems.
Journal ArticleDOI
RAPD Assessment for Identification of Clonal Identity and Genetic Stability of in vitro Propagated Chestnut Hybrids
TL;DR: Randomly amplified polymorphic DNA (RAPD) was used as a tool to assess the clonal identity of four in vitro propagated chestnut rootstock hybrids, and polymorphism was detected between the material propagated in vitro and the donor plants they originated from.
Journal ArticleDOI
Chlorophyll fluorescence as an indicator of photosynthetic functioning of in vitro grapevine and chestnut plantlets under ex vitro acclimatization
TL;DR: The results taken as a whole suggest that 300 μmol m−2 s−1 is the upper threshold for acclimatization of chestnut although grapevine showed a better response than chestnut to an increase in light.
Journal ArticleDOI
In vitro propagation of chestnut (Castanea sativa×C. crenata): Effects of rooting treatments on plant survival, peroxidase activity and anatomical changes during adventitious root formation
TL;DR: The sequential anatomical changes during the rooting process were similar in both root induction treatments and in the acclimatization stage, 100% survival was obtained with microplants with ex vitro-developed roots, compared to only 50% for microplant with in vitro- developed roots.
Journal ArticleDOI
Antioxidant defence system in plantlets transferred from in vitro to ex vitro: effects of increasing light intensity and CO2 concentration
Luísa C. Carvalho,Sara Amâncio +1 more
TL;DR: The results suggest that GSH and e are reliable indicators of autotrophic functioning, discriminating between the environmental conditions that accelerate the acquisition of full autotrophy.
