Journal ArticleDOI

Alteration of plant physiology by glyphosate and its by-product aminomethylphosphonic acid: an overview

Marcelo Pedrosa Gomes, +7 more
- 01 Sep 2014 - 
TL;DR: The present review provides an overall picture of alterations of plant physiology caused by environmental exposure to glyphosate and its metabolite AMPA, and summarizes their effects on several physiological processes, particularly on photosynthesis, from photochemical events to C assimilation and translocation, as well as oxidative stress.
Journal ArticleDOI

Ecophysiological and anatomical changes due to uptake and accumulation of heavy metal in Brachiaria decumbens

Marcelo Pedrosa Gomes, +4 more
- 01 Oct 2011 - 
TL;DR: Evaluating the effect of levels of soil contamination on biomass production, on photosynthetic characteristics and on anatomical changes in roots and leaves of brachiaria indicates that B. decumbens seems to have some degree of heavy metal tolerance.
Journal ArticleDOI

Differential effects of glyphosate and aminomethylphosphonic acid (AMPA) on photosynthesis and chlorophyll metabolism in willow plants.

Marcelo Pedrosa Gomes, +5 more
- 01 Jun 2016 - 
TL;DR: It is observed that AMPA and glyphosate trigger different mechanisms leading to decreases in chlorophyll content and photosynthesis rates in willow plants, which may be due to various glyphosate:AMPA ratios in those plants.
Journal ArticleDOI

Reactive oxygen species and seed germination

Marcelo Pedrosa Gomes, +2 more
- 01 Jun 2013 - 
TL;DR: Reactive oxygen species (ROS) are continuously produced by the metabolically active cells of seeds, and apparently play important roles in biological processes such as germination and dormancy.
Journal ArticleDOI

Ciprofloxacin induces oxidative stress in duckweed (Lemna minor L.): Implications for energy metabolism and antibiotic-uptake ability.

Marcelo Pedrosa Gomes, +7 more
- 15 Apr 2017 - 
TL;DR: The results indicate that instead of being a photosystem II binding molecule, Cipro induces oxidative stress by targeting the mitochondrial ETC, which would explain the observed effects of the antibiotic on non-target eukaryotic organisms.
