Tammy L. Sage spends much of her time researching Photosynthesis, C4 photosynthesis, Chloroplast, Botany and Vascular bundle. Her study in Photosynthesis is interdisciplinary in nature, drawing from both Evolutionary dynamics, Biological evolution and Function. Tammy L. Sage has included themes like Citric acid cycle and Nitrogen assimilation in her C4 photosynthesis study.

Her biological study spans a wide range of topics, including Convergent evolution and Clade. Her Botany research integrates issues from Caryophyllales and Okenia. Her Vascular bundle study also includes

  • Organelle that connect with fields like Arabidopsis, Mutant and Green fluorescent protein,
  • Plasmodesma together with Callose and Biophysics.

Between 2017 and 2021, her most popular works were:

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

  • Botany
  • Gene
  • Ecology

Her scientific interests lie mostly in C4 photosynthesis, Photosynthesis, Alloteropsis semialata, Developmental change and Anatomy. Her research integrates issues of Carbon gain, Carbon assimilation, Biological evolution, Function and Evolutionary dynamics in her study of C4 photosynthesis.
