Iron (Fe) is an essential micronutrient for plants, as a cofactor in multi-heme cytochromes and within iron-sulfur clusters. However, Fe can be toxic at high concentrations. Free cells disrupt the cell redox balance toward pro-oxidant state, generating oxidative stress. The focuses of this review were to elucidate detoxification strategies used by well describe excess effects on plant body its impact physiological, morphological metabolic traits. Therefore, we highlight importance evaluating...
Potassium (K+) is an essential macro-element for plant growth and development given its implication in major processes such as photosynthesis, osmoregulation, protein synthesis, enzyme function. Using 30-day-old Cakile maritima plants halophyte model grown under K+ deprivation 15 days, it was analyzed at the biochemical level to determine metabolism of reactive oxygen species (ROS), key photorespiratory enzymes, main NADPH-generating systems. starvation-induced oxidative stress noticed by...
Abstract The use of aerial spraying herbicide in large areas is common Brazil, especially glyphosate, which the most extensively used worldwide. A portion can reach non-target species, resulting damage these species and causing severe implications for local biodiversity. Thus, this study aimed to evaluate responses leaves Handroanthus chrysotricus (Mart. Ex DC) Mattos (Bignoniaceae) Garcinia gardneriana (Planch. & Triana) Zappi (Clusiaceae) glyphosate its potential biomonitoring purposes,...
Arsenic (As) pollution is a major environmental concern due to its worldwide distribution and high toxicity organisms. The fern Pityrogramma calomelanos one of the few plant species known be able hyperaccumulate As, although mechanisms involved are largely unknown. This study aimed investigate metabolic adjustments in As‐tolerance P. . For this purpose, ferns with five seven fronds were exposed series As concentrations. Young used for biochemical analysis metabolite profiling using gas...
O objetivo deste trabalho foi avaliar o efeito do silício (Si) no processo infeccioso de Phakopsora pachyrhizi em folíolos soja cultivada solução nutritiva com ou sem Si. Observações realizadas sob microscópio luz e eletrônico varredura indicaram que, nos das plantas supridas Si, as urédias foram menores menor número. Houve redução 27, 23 60% número lesões, fechadas abertas, respectivamente, Plantas Si apresentam sintomas da ferrugem-asiática-da-soja.
Chemical weed control is essential to ensure high levels of productivity in agricultural areas, and glyphosate-based herbicides (GBHs) are the most widely used on a global scale. Glyphosate-based inhibit 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPS) enzyme, which impairs shikimate pathway often leads plant death. However, indirect effects GBHs physiology can also lead The objectives this review discuss biochemical, physiological, structural changes that GBH application produces...
When glyphosate is applied, some of the herbicide can reach adjacent vegetation and impact natural plant community structure diversity over long term. This study evaluated response leaves Zeyheria tuberculosa (Vell.) Bureau ex Verl. (Bignoniaceae) to glyphosate. Plants were exposed aerial applications at concentrations 0, 360, 720, 1080, or 1440 g acid equivalent (a.e.)·ha −1 . The shikimic in herbicide-treated plants always higher than controls. Visual symptoms became apparent four days...
Fluoride (F) is the most phytotoxic atmospheric pollutant. The use of plants for passive or active biomonitoring has been a common strategy to detect abnormal F concentrations. Tree species are mostly used, although high sensitivities some, associated with costly processes plant replacement, will increase cost outlays F-biomonitoring processes. After few days exposure, F-sensitive often die, and must be replaced in stations. We therefore investigated potential grass Panicum maximum...
6-Phosphogluconate dehydrogenase (6PGDH; EC 1.1.1.44) catalyzes the third and irreversible reaction of pentose phosphate pathway (PPP). It carries out oxidative decarboxylation 6-phosphogluconate to yield ribulose-5-phosphate, carbon dioxide NADPH. In higher plants, 6PGDH has several subcellular localizations including cytosol, chloroplast, mitochondria peroxisomes ( Corpas et al., 1998 ; Krepinsky 2001 Mateos 2009 Fernández-Fernández Corpas, 2016; Hölscher 2016 ). Using Arabidopsis thaliana...
