Overview

What is he best known for?

The fields of study he is best known for:

  • Enzyme
  • Gene
  • Botany

His primary areas of study are Biochemistry, Catalase, Superoxide dismutase, Glutathione reductase and Antioxidant. In general Biochemistry, his work in Glutathione, Enzyme, Amino acid synthesis and Methionine is often linked to Homoserine dehydrogenase linking many areas of study. His Catalase research incorporates themes from Peroxidase, Malondialdehyde and Shoot, Horticulture.

His Superoxide dismutase study which covers Lipid peroxidation that intersects with APX. His studies deal with areas such as Botany and Hordeum vulgare as well as Glutathione reductase. In his work, Saccharum officinarum and Food science is strongly intertwined with Reactive oxygen species, which is a subfield of Antioxidant.

His most cited work include:

  • Making the life of heavy metal-stressed plants a little easier (825 citations)
  • Response of antioxidant enzymes to transfer from elevated carbon dioxide to air and ozone fumigation, in the leaves and roots of wild-type and a catalase-deficient mutant of barley (362 citations)
  • Antioxidant enzymes responses to cadmium in radish tissues. (331 citations)

What are the main themes of his work throughout his whole career to date?

Biochemistry, Antioxidant, Horticulture, Superoxide dismutase and Catalase are his primary areas of study. His work on Lysine, Enzyme, Amino acid and Lipid peroxidation as part of general Biochemistry research is often related to Aspartate kinase, thus linking different fields of science. His biological study spans a wide range of topics, including Oxidative stress and Glutathione.

His Horticulture study integrates concerns from other disciplines, such as Photosynthesis, Botany and Nutrient. His Superoxide dismutase study focuses on Glutathione reductase in particular. The study incorporates disciplines such as Peroxidase and Malondialdehyde in addition to Catalase.

He most often published in these fields:

  • Biochemistry (40.70%)
  • Antioxidant (20.16%)
  • Horticulture (19.77%)

What were the highlights of his more recent work (between 2017-2021)?

  • Horticulture (19.77%)
  • Antioxidant (20.16%)
  • Cultivar (5.04%)

In recent papers he was focusing on the following fields of study:

Ricardo Antunes Azevedo mainly focuses on Horticulture, Antioxidant, Cultivar, Shoot and Photosynthesis. The concepts of his Horticulture study are interwoven with issues in Lipid peroxidation, Malondialdehyde, Nutrient and Root hair. His Antioxidant research is multidisciplinary, incorporating elements of Peroxidase, Enzyme and Oxidative stress.

Peroxidase is closely attributed to Glutathione reductase in his study. The Phytotoxicity study combines topics in areas such as Ecotoxicology and Catalase. The subject of his Glutathione research is within the realm of Biochemistry.

Between 2017 and 2021, his most popular works were:

  • Plants facing oxidative challenges—A little help from the antioxidant networks (93 citations)
  • Hormesis in plants under Cd exposure: From toxic to beneficial element? (38 citations)
  • Temporal dynamic responses of roots in contrasting tomato genotypes to cadmium tolerance. (27 citations)

In his most recent research, the most cited papers focused on:

  • Enzyme
  • Gene
  • Botany

The scientist’s investigation covers issues in Horticulture, Nutrient, Cultivar, Toxicity and Superoxide dismutase. His Horticulture research incorporates elements of Ecotoxicology, Mode of action, Metal toxicity and APX. His research in APX intersects with topics in Malondialdehyde, Glutathione reductase and Bioaccumulation.

His study in Superoxide dismutase is interdisciplinary in nature, drawing from both Lactuca, Plastoglobule, Phloem and Catalase. He performs multidisciplinary study on Catalase and Aspartate kinase in his works. His Antioxidant research includes themes of Reactive oxygen species, Oxidative phosphorylation and Biotechnology.
