HAG3, a Histone Acetyltransferase, Affects UV-B Responses by Negatively Regulating the Expression of DNA Repair Enzymes and Sunscreen Content in Arabidopsis thaliana
(Oxford University Press, 2015-04)
Histone acetylation is regulated by histone acetyltransferases and deacetylases. In Arabidopsis, there are 12 histone acetyltransferases and 18 deacetylases. Histone acetyltransferases are organized in four families: ...
HAC1 and HAF1 histone acetyltransferases have different roles in UV-B responses in arabidopsis
(Frontiers Research Foundation, 2017-07)
Arabidopsis has 12 histone acetyltransferases grouped in four families: the GNAT/HAG, the MYST/HAM, the p300/CBP/HAC and the TAFII250/HAF families. We previously showed that ham1 and ham2 mutants accumulated higher damaged ...
Effects of solar ultraviolet radiation on photosynthesis of the marine red tide alga Heterosigma akashiwo (Raphidophyceae)
(Elsevier Science Sa, 2007-02)
In order to assess the short- and long-term impacts of UV radiation (UVR, 280–400 nm) on the red tide alga, Heterosigma akashiwo, we exposed the cells to three different solar radiation treatments (PAB: 280–700 nm, PA: ...
Analytical characterization and purification of a commercial extract of enzymes: a case study
(Elsevier Science, 2014-05-27)
This paper presents a rational strategy to identify and quantify the components of a commercial extract of the lipase B of Candida antarctica that can be extended to the analytical investigation of other crude extracts of ...
UV-B and abscisic acid effects on grape berry maturation and quality
(IOS PRESS, 2013-12)
This review provides an overview of existing literature on the effects of ultraviolet-B (UV-B) radiation and abscisic acid (ABA) on physiological and biochemical aspects affecting grape berry (Vitis vinifera L.) growth, ...
Effects of UV radiation on aquatic ecosystems and interactions with other environmental factors
(Royal Society of Chemistry, 2015-01)
Interactions between climate change and UV radiation are having strong effects on aquatic ecosystems due to feedback between temperature, UV radiation, and greenhouse gas concentration. Higher air temperatures and incoming ...
