Superoxide dismutases and superoxide reductases
Yuewei Sheng,Isabel A. Abreu,Diane E. Cabelli,Michael J. Maroney,Anne-Frances Miller,Miguel Teixeira,Joan Selverstone Valentine,Joan Selverstone Valentine +7 more
TL;DR: The SORs and three very different types of SOD enzymes are redox-active metalloenzymes that have evolved entirely independently from one another for the purpose of lowering superoxide concentrations, suggesting that, from the start of the rise of O2 on Earth, the chemistry of superoxide has been an important factor during evolution.
Journal ArticleDOI
Superoxide dismutases-a review of the metal-associated mechanistic variations.
Isabel A. Abreu,Diane E. Cabelli +1 more
TL;DR: This review describes copper, zinc superoxide dismutase and manganese superoxide Dismutase in terms of the details of their catalytic properties, with an emphasis on the mechanistic differences between the enzymes.
Journal ArticleDOI
The Arabidopsis E3 SUMO ligase SIZ1 regulates plant growth and drought responses.
TL;DR: It is concluded that SIZ1 regulates Arabidopsis growth and that this SUMO E3 ligase plays a role in drought stress response likely through the regulation of gene expression.
Journal ArticleDOI
Recent Updates on Salinity Stress in Rice: From Physiological to Molecular Responses
Sónia Negrão,Brigitte Courtois,Nourollah Ahmadi,Isabel A. Abreu,Nelson J. M. Saibo,Margarida Oliveira +5 more
TL;DR: The most recent data on the salinity effect on rice physiology and stress adaptation, including implications on growth regulation and reproductive development are presented and the most promising candidate genes involved in salt stress response are focused on.
Journal ArticleDOI
New allelic variants found in key rice salt-tolerance genes: an association study.
Sónia Negrão,M. Cecília Almadanim,Inês S. Pires,Isabel A. Abreu,João Maroco,Brigitte Courtois,Glenn B. Gregorio,Kenneth L. McNally,M. Margarida Oliveira +8 more
TL;DR: Five nonsynonymous SNPs significantly associated with salt-stress traits are found, including a T67K mutation that may cause the destabilization of one transmembrane domain in Os HKT1;5, and a P140A alteration that significantly increases the probability of OsHKT 1;5 phosphorylation.
