Regulation of Transpiration by Stomata02:04

Regulation of Transpiration by Stomata

28.6K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Light Acquisition02:16

Light Acquisition

8.5K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

  • To facilitate the development of resilient crop varieties with optimized stomatal patterning.

Main Methods:

  • Non-destructive imaging of leaf surfaces using a handheld microscope in the plant's growing environment.
  • Automated image analysis employing a machine learning model for stomatal detection, counting, and measurement.
  • Validation of the machine learning model against manual measurements, showing high accuracy (88-99%).

Main Results:

  • The developed method significantly reduces time for stomatal data acquisition and analysis.
  • Accurate measurements of stomatal number, size, and aperture were achieved.
  • Contrasting stomatal phenotypes were rapidly identified using the new method.
