Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Enzyme
  • Horticulture

Rajaram Panneerselvam focuses on Catharanthus roseus, Botany, Antioxidant, Horticulture and Catalase. Rajaram Panneerselvam has included themes like Proline, Proline oxidase, Salinity and Sowing in his Catharanthus roseus study. In the subject of general Botany, his work in Shoot, Photosynthetic pigment, Chlorophyll and Photosynthesis is often linked to Secondary metabolite, thereby combining diverse domains of study.

His work in Photosynthesis addresses subjects such as Plant morphology, which are connected to disciplines such as Drought tolerance. Many of his research projects under Antioxidant are closely connected to Ascorbic acid with Ascorbic acid, tying the diverse disciplines of science together. His studies examine the connections between Horticulture and genetics, as well as such issues in Catharanthus, with regards to Ecophysiology.

His most cited work include:

  • Drought stress in plants: A review on morphological characteristics and pigments composition (642 citations)
  • Antioxidant defense responses: physiological plasticity in higher plants under abiotic constraints (298 citations)
  • Understanding water deficit stress-induced changes in the basic metabolism of higher plants – biotechnologically and sustainably improving agriculture and the ecoenvironment in arid regions of the globe (240 citations)

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

Botany, Horticulture, Antioxidant, Superoxide dismutase and Triadimefon are his primary areas of study. His work on Proline expands to the thematically related Botany. The Chlorophyll, Paclobutrazol and Shoot research Rajaram Panneerselvam does as part of his general Horticulture study is frequently linked to other disciplines of science, such as Hexaconazole, therefore creating a link between diverse domains of science.

His work on Lipid peroxidation and DPPH as part of general Antioxidant study is frequently connected to Ascorbic acid, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His Superoxide dismutase study combines topics in areas such as Peroxidase, Polyphenol oxidase and Catalase. His Triadimefon research includes themes of Raphanus, Sugar, Biochemistry and Seedling.

He most often published in these fields:

  • Botany (61.70%)
  • Horticulture (50.00%)
  • Antioxidant (36.17%)

What were the highlights of his more recent work (between 2011-2019)?

  • Botany (61.70%)
  • Antioxidant (36.17%)
  • Superoxide dismutase (31.91%)

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

Rajaram Panneerselvam mainly investigates Botany, Antioxidant, Superoxide dismutase, Rauvolfia serpentina and Catalase. His study connects Horticulture and Botany. His research in the fields of Lipid peroxidation overlaps with other disciplines such as Ascorbic acid.

His Superoxide dismutase research incorporates elements of Proline and Osmoprotectant. His Catalase research focuses on Food science and how it connects with Elicitor. His work in Drought stress covers topics such as Setaria which are related to areas like Chlorophyll.

Between 2011 and 2019, his most popular works were:

  • ROS Scavenging System, Osmotic Maintenance, Pigment and Growth Status of Panicum sumatrense Roth. Under Drought Stress (43 citations)
  • Studies on methanolic extract of Rauvolfia species from Southern Western Ghats of India – In vitro antioxidant properties, characterisation of nutrients and phytochemicals (27 citations)
  • Biochemical Alterations in White Yam (Dioscorea rotundata Poir.) under Triazole Fungicides : Impacts on Tuber Quality (18 citations)

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

  • Botany
  • Enzyme
  • Ecology

The scientist’s investigation covers issues in Rauvolfia serpentina, Botany, Antioxidant, Ascorbic acid and Panicum sumatrense. His research on Botany often connects related topics like Horticulture. His Antioxidant research is multidisciplinary, relying on both Panicum, Enzyme assay and Food science.

Ascorbic acid overlaps with fields such as Triadimefon, Fungicide and Anthocyanin in his research. Rajaram Panneerselvam interconnects Proline, Superoxide dismutase, Catalase, Abiotic component and Drought tolerance in the investigation of issues within Panicum sumatrense. His work carried out in the field of Catalase brings together such families of science as Osmoprotectant, Chlorophyll and Agronomy.
