Effect of UV-B radiation on the contents of UV-B absorbing compounds and photosynthetic parameters in Parmotrema austrosinense from two contrasting habitats
(Wiley Blackwell Publishing, Inc, 2018-09)
We studied the resistance of Parmotrema austrosinense to UV-B stress. We focused on the effects of a high dose UV-B radiation on the content of chlorophylls, carotenoids and UV-B screening compounds. Photosynthetic parameters ...
Functional acclimation to solar UV-B radiation in Gunnera magellanica, a native plant species of southernmost Patagonia
(Wiley Blackwell Publishing, Inc, 2003-12)
The ecosystems of Tierra del Fuego (in southern Patagonia, Argentina) are seasonally exposed to elevated levels of ultraviolet-B radiation (UV-B: 280-315 nm), due to the passage of the 'ozone hole' over this region. In the ...

Solar UV-B and ABA Are Involved in Phenol Metabolism of Vitis vinifera L. Increasing Biosynthesis of Berry Skin Polyphenols
(American Chemical Society, 2011-05)
It has been previously found that abscisic acid (ABA) participates in the activation of grapevine leaf tissue defense against potentially damaging effects of solar ultraviolet-B radiation (UV-B), apparently by triggering ...
Composite films with UV barrier capacity to minimize flavored waters degradation
(Elsevier, 2019-09)
Secondary packages for commercial flavored waters were developed from composite films to reduce beverage UV degradation. Bottle packs of orange and grapefruit flavored waters (OFW and GFW), were wrapped with films based ...

An increase in the concentration of abscisic acid is critical for nitric oxide-mediated plant adaptive responses to UV-B irradiation
(Wiley Blackwell Publishing, Inc, 2009-12)
• Here, the link between UV-B stimulus and the abscisic acid (ABA)-induced nitric oxide (NO) synthesis pathway was studied in leaves of maize (Zea mays). • The ABA concentration increased by 100% in UV-B irradiated leaves. ...
Differential UVR8 Signal across the Stem Controls UV-B-Induced Inflorescence Phototropism
(American Society of Plant Biologist, 2019-09)
In the course of evolution, plants have developed mechanisms that orient their organs toward the incoming light. At the seedling stage, positive phototropism is mainly regulated by phototropin photoreceptors in blue and ...
Chromosomal loci important for cotyledon opening under UV-B in Arabidopsis thaliana
(BioMed Central, 2010-06)
Background: Understanding of the genetic architecture of plant UV-B responses allows extensive targeted testing of candidate genes or regions, along with combinations of those genes, for placement in metabolic or signal ...
