Eiji Gotoh, Adaptation to weak light environments in plants -Chloroplast photorelocation movements and leaf anatomy changes-
, International Congress on Photosynthesis Research 2022, 2022.08, More than 70% of the plant species on Earth thrive on the forest floor, where trees obstruct sunlight. These plants are exposed to a wide range of light intensities, ranging from dim light (only a fraction of the sunlight) to direct sunlight filtering through the trees. While light is essential for photosynthesis and provides energy to plants, strong light can be detrimental. As a result, plants have developed mechanisms to sense the direction and intensity of light, allowing them to adapt to varying light conditions at the organelle, cellular, and tissue levels.
One of the plant responses to the light environment is chloroplast photorelocation movements. Plants can modulate light absorption in their leaves by altering the intracellular arrangement of chloroplasts in response to light intensity. This enables them to optimize photosynthesis in low-light conditions while safeguarding against light-induced damage in high-light conditions. Through studying model plant mutants, our research group has demonstrated the significance of changes in chloroplast localization for plant growth. Additionally, we have researched 250 plant species on forest floors throughout Japan, examining the chloroplast movement and the morphology of palisade cells. Our findings indicate that cell shape is adapted to the specific light environment. In this presentation, I would like to share our latest discoveries obtained through a comprehensive analysis of wild plants.. |
