Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Botany
  • Fungus

His primary scientific interests are in Botany, Strigolactone, Medicago truncatula, Mycorrhiza and Cell biology. His research in Botany intersects with topics in Rhizophagus irregularis, Organogenesis and Symbiosis. His studies deal with areas such as Karrikin, Orobanche and Parasitic plant as well as Strigolactone.

His Karrikin study integrates concerns from other disciplines, such as Apical dominance, Shoot and Apocarotenoid. As a part of the same scientific family, Guillaume Bécard mostly works in the field of Medicago truncatula, focusing on Sinorhizobium meliloti and, on occasion, Bioassay. His biological study spans a wide range of topics, including Arbuscular mycorrhiza, Ecology, Mycelium and Metabolism.

His most cited work include:

  • Strigolactone inhibition of shoot branching (1446 citations)
  • Strigolactone inhibition of shoot branching (1446 citations)
  • Fungal lipochitooligosaccharide symbiotic signals in arbuscular mycorrhiza (691 citations)

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

His main research concerns Botany, Symbiosis, Mycorrhiza, Fungus and Medicago truncatula. His Botany research incorporates elements of Glomeromycota, Strigolactone and Cell biology. The various areas that Guillaume Bécard examines in his Strigolactone study include Karrikin, Phosphate and Parasitic plant.

Guillaume Bécard has included themes like Ecology, Colonization and Gene in his Symbiosis study. The study incorporates disciplines such as Daucus carota, Glomus, Rhizobiaceae, Arbuscular mycorrhiza and Phycomycetes in addition to Mycorrhiza. His Medicago truncatula research incorporates themes from Host, Sinorhizobium meliloti and Nod factor.

He most often published in these fields:

  • Botany (107.87%)
  • Symbiosis (61.80%)
  • Mycorrhiza (34.83%)

What were the highlights of his more recent work (between 2014-2021)?

  • Botany (107.87%)
  • Symbiosis (61.80%)
  • Fungus (30.34%)

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

Guillaume Bécard spends much of his time researching Botany, Symbiosis, Fungus, Medicago truncatula and Cell biology. His Botany research includes themes of Arbuscular mycorrhizal fungi, Auxin and Colonization. Guillaume Bécard interconnects Spore and Hypha in the investigation of issues within Symbiosis.

His studies in Fungus integrate themes in fields like Glomerales, Diversisporales, Obligate, Phylogenomics and Glomeromycota. In his research, Nod and Kingdom Fungi is intimately related to Heritability, which falls under the overarching field of Medicago truncatula. His research integrates issues of Regulation of gene expression, Downregulation and upregulation, Gene and microRNA in his study of Cell biology.

Between 2014 and 2021, his most popular works were:

  • Primary transcripts of microRNAs encode regulatory peptides (197 citations)
  • A Survey of the Gene Repertoire of Gigaspora rosea Unravels Conserved Features among Glomeromycota for Obligate Biotrophy. (70 citations)
  • Sl-IAA27 regulates strigolactone biosynthesis and mycorrhization in tomato (var. MicroTom). (36 citations)

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

  • Gene
  • Botany
  • Fungus

Guillaume Bécard mainly focuses on Cell biology, Botany, Fungus, Regulation of gene expression and Symbiosis. In his study, Medicago truncatula is inextricably linked to Gene, which falls within the broad field of Cell biology. His work blends Botany and MRNA Sequencing studies together.

His Fungus research is multidisciplinary, incorporating perspectives in Cleavage, Meristem, Obligate, Phylogenomics and Glomeromycota. His study looks at the relationship between Regulation of gene expression and topics such as microRNA, which overlap with Arbuscular mycorrhiza. His Symbiosis research integrates issues from Strigolactone, Gene silencing, Auxin and Metabolic pathway.
