Effect of UV-B radiation on the photoprotective and antioxidant response in Vaccinium corymbosum L.: An approach to the UV-B resistance mechanisms.
(2017)
Despite the Montreal protocol success and the eventual recovery of the ozone layer over Antarctica, there are still concerns about increased levels of ultraviolet-B (UV-B) radiation in the Southern Hemisphere. It is expected ...
Acclimation to UV irradiance in Gracilaria chilensis Bird, McLachlan & Oliveira (Gigartinales, Rhodophyta)
(Springer Netherlands, 1996)
Photoautotrophs can cope with an increase in ultraviolet (UV) irradiance in the aquatic environment, through protection and acclimation mechanisms (i.e. synthesis of UV-absorbing compounds). This capacity has been proven ...
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 ...
Sensitivity of yellow passion fruit plants to ultraviolet-B radiation
(2012)
The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted ...
Effects of UV-B radiation on Lecanicillium spp., biological control agents of the coffee leaf rust pathogen
(Sociedade Brasileira de Fitopatologia, 2014-10-01)
Coffee leaf rust is the main disease of coffee and its causal agent is naturally hyperparasited by Lecanicillium lecanii, indicating its potential for biocontrol. Ultraviolet-B (UV-B) radiation is an important factor that ...
UV-B impairs growth and gas exchange in grapevines grown in high altitude
(Wiley Blackwell Publishing, Inc, 2013-09)
We previously demonstrated that solar ultraviolet-B (UV-B) radiation levels in high altitude vineyards improve berry quality in Vitis vinifera cv. Malbec, but also reduce berry size and yield, possibly as a consequence of ...
Solar UV-B radiation affects leaf quality and insect herbivory in the southern beech tree Nothofagus antarctica
(Springer, 2004-03)
We examined the effects of solar ultraviolet-B (UV-B) radiation on plant-insect interactions in Tierra del Fuego (55°S), Argentina, an area strongly affected by ozone depletion because of its proximity to Antarctica. Solar ...
Role of constitutive nitric oxide synthases in the dynamic regulation of the autophagy response of keratinocytes upon UVB exposure
(Royal Society of Chemistry, 2020)
Ultraviolet B (UVB) radiation induces autophagy responses, which play a role in the regulation of the oncogenic processes of irradiated cells. However, the mechanism of autophagy responses post-UVB irradiation remains to ...
Analysis of UV-B regulated miRNAs and their targets in maize leaves
(Landes Bioscience, 2013-10)
UV-B radiation elicits physiological and developmental changes in plants. In this work, to characterize the mechanisms of gene regulation by UV-B radiation, the global miRNA expression profiles in juvenile maize leaves ...
