Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Botany
  • Enzyme

Rajbir S. Sangwan mainly focuses on Biochemistry, Cell biology, Transformation, Phloem and Mutant. His work on Plant physiology expands to the thematically related Biochemistry. His biological study spans a wide range of topics, including Arabidopsis thaliana, Anther dehiscence, Pollen maturation and Botany.

His work carried out in the field of Botany brings together such families of science as Organogenesis and Cytokinin, Auxin. His Transformation research integrates issues from Explant culture and Cell division. His Brassinosteroid and Arabidopsis study in the realm of Mutant connects with subjects such as Abiotic component.

His most cited work include:

  • Trehalose and plant stress responses: friend or foe? (244 citations)
  • Glutamine Synthetase in the Phloem Plays a Major Role in Controlling Proline Production (174 citations)
  • Characterization of competent cells and early events of Agrobacterium-mediated genetic transformation in Arabidopsis thaliana (172 citations)

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

Rajbir S. Sangwan spends much of his time researching Botany, Biochemistry, Explant culture, Callus and Transformation. His Botany study incorporates themes from Cytokinin and Somatic embryogenesis, Tissue culture. His work in Biochemistry tackles topics such as Phloem which are related to areas like Cytosol and Glutamine synthetase.

His work on Micropropagation as part of general Explant culture research is often related to Vigna subterranea, thus linking different fields of science. His Callus research is multidisciplinary, incorporating elements of Datura, Murashige and Skoog medium and Biennial plant. The various areas that Rajbir S. Sangwan examines in his Transformation study include Genetically modified crops and Marker gene.

He most often published in these fields:

  • Botany (53.85%)
  • Biochemistry (24.18%)
  • Explant culture (24.18%)

What were the highlights of his more recent work (between 2007-2017)?

  • Botany (53.85%)
  • Arabidopsis (12.09%)
  • Mutant (12.09%)

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

Botany, Arabidopsis, Mutant, Arabidopsis thaliana and Biochemistry are his primary areas of study. His research integrates issues of Morphogenesis and Horticulture in his study of Botany. His studies deal with areas such as Organogenesis, Immunogold labelling, Transformation and Auxin as well as Arabidopsis.

His research in Organogenesis intersects with topics in Lateral root formation, Shoot, Meristem, Cell biology and Cytokinin. The study incorporates disciplines such as Biotic stress, Abiotic stress and Sugar in addition to Mutant. The Arabidopsis thaliana study combines topics in areas such as Picloram, Agrobacterium, Agrobacterium tumefaciens, Marker gene and Molecular biology.

Between 2007 and 2017, his most popular works were:

  • Trehalose and plant stress responses: friend or foe? (244 citations)
  • De novo shoot organogenesis: from art to science (118 citations)
  • The Arabidopsis sweetie mutant is affected in carbohydrate metabolism and defective in the control of growth, development and senescence (50 citations)

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

  • Gene
  • Botany
  • Enzyme

His scientific interests lie mostly in Mutant, Biochemistry, Morphogenesis, Arabidopsis and Botany. His Mutant research is multidisciplinary, incorporating perspectives in Biotic stress, Plant physiology, Trehalose, Plant cell and Plant defense against herbivory. The Arabidopsis thaliana, Carbohydrate metabolism and Abiotic stress research Rajbir S. Sangwan does as part of his general Biochemistry study is frequently linked to other disciplines of science, such as Abiotic component, therefore creating a link between diverse domains of science.

His Morphogenesis research includes themes of Organogenesis, Auxin, Shoot and Cell biology. His work deals with themes such as Cytokinin and Meristem, which intersect with Arabidopsis. The study of Botany is intertwined with the study of Doubled haploidy in a number of ways.
