Overview

What is he best known for?

The fields of study he is best known for:

  • Bacteria
  • Enzyme
  • Botany

Tongmin Sa mainly investigates Botany, Methylobacterium, Methylobacterium oryzae, Rhizosphere and Agronomy. His Botany research incorporates themes from Oryza sativa and Pepper, Horticulture. His studies in Horticulture integrate themes in fields like Catalase, Monocrotophos, Ajmalicine and Bacteria.

He combines subjects such as Chlorophyll, Mycorrhiza and Spore with his study of Methylobacterium oryzae. His Rhizosphere study integrates concerns from other disciplines, such as Host, Soil microbiology and Microbial inoculant. His Agronomy research integrates issues from Salinity, Soil salinity, Agriculture, Soil test and Ecosystem.

His most cited work include:

  • Enhancement of growth and salt tolerance of red pepper seedlings (Capsicum annuum L.) by regulating stress ethylene synthesis with halotolerant bacteria containing 1-aminocyclopropane-1-carboxylic acid deaminase activity. (167 citations)
  • Characterization of 1-aminocyclopropane-1-carboxylate (ACC) deaminase containing Methylobacterium oryzae and interactions with auxins and ACC regulation of ethylene in canola ( Brassica campestris ) (91 citations)
  • A meta-analysis of arbuscular mycorrhizal effects on plants grown under salt stress. (84 citations)

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

His primary areas of investigation include Botany, Horticulture, Bacteria, Agronomy and Inoculation. His biological study spans a wide range of topics, including Methylobacterium and Rhizosphere, Rhizobacteria. His Horticulture study combines topics in areas such as Photosynthesis, ACC deaminase and Pseudomonas.

Tongmin Sa has included themes like Thiosulfate, Food science, Gene and Microbiology in his Bacteria study. The various areas that he examines in his Agronomy study include Soil water, Salinity and Nutrient. His research investigates the connection with Inoculation and areas like Shoot which intersect with concerns in Symbiosis.

He most often published in these fields:

  • Botany (41.80%)
  • Horticulture (23.81%)
  • Bacteria (22.22%)

What were the highlights of his more recent work (between 2016-2021)?

  • Horticulture (23.81%)
  • Botany (41.80%)
  • Salinity (9.52%)

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

His main research concerns Horticulture, Botany, Salinity, Bacteria and Rhizobacteria. The concepts of his Horticulture study are interwoven with issues in Photosynthesis and Stomatal conductance. His studies deal with areas such as Proteobacteria, Verrucomicrobia and Herbaspirillum as well as Botany.

His Salinity study frequently draws parallels with other fields, such as Methylobacterium oryzae. Tongmin Sa has researched Bacteria in several fields, including Food science and Plant growth. His research integrates issues of Bioremediation, Microorganism, Phytoremediation, Environmental remediation and Nutrient in his study of Rhizobacteria.

Between 2016 and 2021, his most popular works were:

  • Plant–microbiome interactions: from community assembly to plant health (83 citations)
  • Characterizing endophytic competence and plant growth promotion of bacterial endophytes inhabiting the seed endosphere of Rice. (58 citations)
  • Beneficial Soil Bacterium Pseudomonas frederiksbergensis OS261 Augments Salt Tolerance and Promotes Red Pepper Plant Growth. (36 citations)

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

  • Bacteria
  • Enzyme
  • Botany

His primary areas of study are Botany, Salinity, Soil water, Proteobacteria and Horticulture. His work on Shoot as part of general Botany study is frequently connected to Hyaline layer, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His work on Soil salinity as part of general Salinity study is frequently linked to Ion transporter, bridging the gap between disciplines.

His study in Soil water is interdisciplinary in nature, drawing from both Verrucomicrobia, Bacterial phyla and Microbial population biology. The Proteobacteria study combines topics in areas such as Oryza and Oryza sativa. As a part of the same scientific study, Tongmin Sa usually deals with the Horticulture, concentrating on Pseudomonas frederiksbergensis and frequently concerns with Superoxide dismutase, Biofertilizer and Agronomy.
