Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Enzyme
  • Fungus

Juan A. Ocampo focuses on Botany, Mycorrhiza, Glomus, Arbuscular mycorrhiza and Phycomycetes. His Botany study combines topics from a wide range of disciplines, such as Pycnoporus cinnabarinus and Rhizobiaceae. His Mycorrhiza research includes elements of Fungi imperfecti, Microbiology, Defence mechanisms, Elicitor and Pseudomonas syringae.

His research integrates issues of Lactuca and Spore germination in his study of Glomus. His Arbuscular mycorrhiza research incorporates elements of Mutualism, Abscisic acid, Biosynthesis, Mutant and Plant physiology. His Phycomycetes study integrates concerns from other disciplines, such as Salicylic acid, Nicotiana tabacum and Solanaceae.

His most cited work include:

  • Regulation of the plant defence response in arbuscular mycorrhizal symbiosis. (273 citations)
  • FACTORS AFFECTING THE VESICULAR-ARBUSCULAR INFECTION AND MYCORRHIZAL DEPENDENCY OF THIRTEEN WHEAT CULTIVARS (267 citations)
  • Induction of Ltp (lipid transfer protein) and Pal (phenylalanine ammonia‐lyase) gene expression in rice roots colonized by the arbuscular mycorrhizal fungus Glomus mosseae (131 citations)

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

His primary areas of study are Botany, Mycorrhiza, Glomus, Phycomycetes and Arbuscular mycorrhiza. His Colonization research extends to the thematically linked field of Botany. His Mycorrhiza study combines topics in areas such as Poaceae, Agronomy, Plant physiology, Fungi imperfecti and Mycelium.

He focuses mostly in the field of Glomus, narrowing it down to topics relating to Spore germination and, in certain cases, Hyphal growth. His Phycomycetes research includes themes of Lactuca, Liliaceae and Solanaceae. His biological study spans a wide range of topics, including Jasmonic acid, Glomeromycota and Mutant.

He most often published in these fields:

  • Botany (81.16%)
  • Mycorrhiza (50.72%)
  • Glomus (47.10%)

What were the highlights of his more recent work (between 2011-2020)?

  • Botany (81.16%)
  • Arbuscular mycorrhiza (18.12%)
  • Rhizophagus irregularis (5.07%)

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

The scientist’s investigation covers issues in Botany, Arbuscular mycorrhiza, Rhizophagus irregularis, Horticulture and Inoculation. His Botany research incorporates themes from Oxidative stress, Mycorrhiza and Mutant. His Mycorrhiza research focuses on subjects like Plant physiology, which are linked to Phosphate and Reactive oxygen species.

His Arbuscular mycorrhiza research is multidisciplinary, incorporating perspectives in Jasmonic acid and Oxylipin. The various areas that Juan A. Ocampo examines in his Rhizophagus irregularis study include Shoot, Dry weight, Straw and Olea. His research investigates the connection with Inoculation and areas like Fungus which intersect with concerns in Cultivar and Fusarium oxysporum.

Between 2011 and 2020, his most popular works were:

  • Role of arbuscular mycorrhizal fungus Rhizophagus custos in the dissipation of PAHs under root-organ culture conditions (44 citations)
  • A comparison of wild-type, old and modern tomato cultivars in the interaction with the arbuscular mycorrhizal fungus Glomus mosseae and the tomato pathogen Fusarium oxysporum f. sp. lycopersici. (40 citations)
  • Late activation of the 9-oxylipin pathway during arbuscular mycorrhiza formation in tomato and its regulation by jasmonate signalling (37 citations)

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

  • Botany
  • Enzyme
  • Fungus

Juan A. Ocampo mainly investigates Botany, Arbuscular mycorrhiza, Gene, Antioxidant and Oxidative stress. He studies Solanum, a branch of Botany. His Solanum research integrates issues from Rhizophagus irregularis, Reactive oxygen species, Mycorrhiza and Plant physiology.

The Arbuscular mycorrhiza study combines topics in areas such as Glomus, Inoculation, Cultivar and Fusarium. His studies deal with areas such as Endogeny and Calcium as well as Gene. His research in Antioxidant intersects with topics in Glutathione, Penicillium and Horticulture.
