Webster

photo-epinasty (n.)

A disproportionately rapid growth of the upper surface of dorsiventral organs, such as leaves, through the stimulus of exposure to light.

photo-epinasty Sentence Examples

  1. Photo-epinasty is a physiological response exhibited by certain plants where their leaves curl downwards in response to bright light.
  2. The photo-epinasty mechanism helps plants avoid photoinhibition by reducing excessive sunlight exposure to their photosynthetic apparatus.
  3. Legumes and members of the Cucurbitaceae family commonly display photo-epinasty as an adaptive response to high irradiance.
  4. Photo-epinasty is triggered by blue light-absorbing photoreceptors, which activate a signaling cascade leading to leaf movement.
  5. Phytochrome B is the primary photoreceptor involved in mediating photo-epinasty in response to changes in the red to far-red light ratio.
  6. Blue light induces a rapid photo-epinastic response, while far-red light alleviates the response, allowing leaves to return to their original position.
  7. The photo-epinastic response is influenced by environmental cues such as temperature, light intensity, and developmental stage of the plant.
  8. Photo-epinasty is a reversible process, with leaves recovering their normal orientation once exposed to lower light intensities.
  9. The photo-epinastic response plays a role in optimizing leaf orientation for efficient light capture and photosynthesis under varying light conditions.
  10. Studying photo-epinasty provides insights into the complex light-signaling pathways that regulate plant growth and development.
