Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Gene
  • Photosynthesis

Botany, Photosynthesis, Horticulture, Acclimatization and Chlorophyll are his primary areas of study. His research is interdisciplinary, bridging the disciplines of Nutrient and Botany. José C. Ramalho combines topics linked to Chlorophyll a with his work on Photosynthesis.

His Horticulture study combines topics in areas such as Catalase, Superoxide dismutase and Antioxidant. As part of one scientific family, José C. Ramalho deals mainly with the area of Acclimatization, narrowing it down to issues related to the Canephora, and often APX. José C. Ramalho interconnects Agronomy, Quercus suber, Chlorophyll fluorescence and Photosystem II in the investigation of issues within Stomatal conductance.

His most cited work include:

  • Impacts of drought and temperature stress on coffee physiology and production: a review (285 citations)
  • Comparison of resistance to drought of three bean cultivars (126 citations)
  • Manganese accumulation in rice: implications for photosynthetic functioning. (113 citations)

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

His main research concerns Horticulture, Photosynthesis, Botany, Agronomy and Stomatal conductance. His Coffea canephora, Cultivar and Canephora study, which is part of a larger body of work in Horticulture, is frequently linked to Context, bridging the gap between disciplines. His Photosynthesis research integrates issues from Acclimatization, Chlorophyll and Coffea arabica.

His Botany research includes themes of Actinorhizal plant and Frankia. In the subject of general Agronomy, his work in Crop is often linked to Shading, thereby combining diverse domains of study. His Stomatal conductance study incorporates themes from Water-use efficiency and Plant physiology.

He most often published in these fields:

  • Horticulture (59.84%)
  • Photosynthesis (49.00%)
  • Botany (36.55%)

  • Horticulture (59.84%)
  • Photosynthesis (49.00%)
  • Biofortification (20.08%)

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

His primary areas of study are Horticulture, Photosynthesis, Biofortification, Agronomy and Context. His biological study spans a wide range of topics, including Acclimatization and Transpiration. His Photosynthesis research is multidisciplinary, incorporating elements of Coffea arabica and Drought tolerance.

The various areas that he examines in his Biofortification study include Biotechnology and Oryza sativa. José C. Ramalho studies Agronomy, focusing on Crop in particular. His RuBisCO research incorporates themes from Photosynthetic capacity, Chlorophyll and Photosystem.

Between 2018 and 2021, his most popular works were:

  • Why could the coffee crop endure climate change and global warming to a greater extent than previously estimated (36 citations)
  • Why could the coffee crop endure climate change and global warming to a greater extent than previously estimated (36 citations)
  • SELENIUM BIOFORTIFICATION OF RICE THROUGH FOLIAR APPLICATION WITH SELENITE AND SELENATE (14 citations)

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

  • Botany
  • Gene
  • Ecology

José C. Ramalho spends much of his time researching Horticulture, Photosynthesis, Acclimatization, Drought tolerance and RuBisCO. Horticulture is frequently linked to Genetic divergence in his study. His Photosynthesis research focuses on subjects like Agronomy, which are linked to Nutrient.

His Acclimatization research is multidisciplinary, relying on both Membrane fluidity, Lipid metabolism, Food science and Membrane lipids. The Drought tolerance study combines topics in areas such as Zeaxanthin, Photoprotection, Primary metabolite, Stomatal conductance and Biomass partitioning. His study in RuBisCO is interdisciplinary in nature, drawing from both AMAX, Photosystem and Vigna.
