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