Overview

What is he best known for?

The fields of study he is best known for:

  • Photosynthesis
  • Gene
  • Metabolism

His primary areas of investigation include Photosynthesis, Carbon dioxide, Botany, Photochemistry and Isoprene synthase. Agu Laisk has included themes like Environmental chemistry, Electron transport chain, Chloroplast and Plastoquinone in his Photosynthesis study. His studies deal with areas such as Ozone concentration, Ozone and Water vapor as well as Environmental chemistry.

His Electron transport chain research is multidisciplinary, incorporating elements of Cytochrome b6f complex, Singlet oxygen, Photoinhibition and Electron transfer. His work carried out in the field of Photochemistry brings together such families of science as Quantum yield and Quenching. He works mostly in the field of P700, limiting it down to topics relating to Photosystem and, in certain cases, Photosystem I, as a part of the same area of interest.

His most cited work include:

  • Ozone concentration in leaf intercellular air spaces is close to zero. (392 citations)
  • The interplay between limiting processes in C3 photosynthesis studied by rapid-response gas exchange using transgenic tobacco impaired in photosynthesis (105 citations)
  • Calculation of Leaf Photosynthetic Parameters Considering the Statistical Distribution of Stomatal Apertures (100 citations)

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

His main research concerns Photosynthesis, Photochemistry, Electron transport chain, Photosystem I and Photosystem II. His Photosynthesis research includes elements of Biophysics and Carbon dioxide. The study incorporates disciplines such as Cytochrome b6f complex, Quenching, Reaction rate constant and Chlorophyll fluorescence in addition to Photochemistry.

The various areas that Agu Laisk examines in his Electron transport chain study include Electron transfer and Analytical chemistry. His work on P700 as part of general Photosystem I research is frequently linked to Far-red, thereby connecting diverse disciplines of science. His P680 study, which is part of a larger body of work in Photosystem II, is frequently linked to Oxygen evolution, bridging the gap between disciplines.

He most often published in these fields:

  • Photosynthesis (60.92%)
  • Photochemistry (35.63%)
  • Electron transport chain (31.03%)

What were the highlights of his more recent work (between 2010-2020)?

  • Photosystem II (29.89%)
  • Photochemistry (35.63%)
  • Photosynthesis (60.92%)

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

Agu Laisk spends much of his time researching Photosystem II, Photochemistry, Photosynthesis, Electron transport chain and Chlorophyll fluorescence. Agu Laisk focuses mostly in the field of Photosystem II, narrowing it down to matters related to Plastoquinone and, in some cases, Cytochrome b6f complex and Recombination. His Photochemistry study combines topics in areas such as Yield, Quantum yield, P680 and P700.

Photosynthesis is a subfield of Botany that Agu Laisk investigates. His research investigates the connection between Electron transport chain and topics such as Analytical chemistry that intersect with problems in Amaranth. His Chlorophyll fluorescence course of study focuses on Quenching and Photosynthetic reaction centre and Saturation.

Between 2010 and 2020, his most popular works were:

  • Action spectra of photosystems II and I and quantum yield of photosynthesis in leaves in State 1. (53 citations)
  • Induction of a longer-term component of isoprene release in darkened aspen leaves: origin and regulation under different environmental conditions (39 citations)
  • Competition between isoprene emission and pigment synthesis during leaf development in aspen (37 citations)

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

  • Photosynthesis
  • Gene
  • Metabolism

Agu Laisk mainly investigates Botany, Carbon dioxide, Photosynthesis, Oxygen and Analytical chemistry. Botany is frequently linked to Biophysics in his study. His Carbon dioxide study combines topics from a wide range of disciplines, such as Pentanes and Photosynthetic pigment.

His Photosynthesis study incorporates themes from Electron transport chain and Amaranth. His Oxygen research is multidisciplinary, incorporating perspectives in Biphasic kinetics, Compensation point and Chlororespiration. His Analytical chemistry research incorporates themes from Yield, Photochemistry, Quantum yield and Photosystem II.
