Wild tomatoes, which grow wild mainly in the Andes Mountains, are adapted to a variety of natural environments (temperature, rainfall, altitude, etc.), and may have traits that are useful to humans. Photosynthesis is the most important metabolism that determines plant productivity, but there are currently no studies that have comprehensively investigated the photosynthetic characteristics of wild tomatoes. In this study, we compared the photosynthetic characteristics of eight wild tomatoes and two cultivated tomatoes, and found wild tomatoes with higher photosynthetic capacity than cultivated tomatoes, and that these photosynthetic characteristics are related to stomatal morphology and native environment.
The results of this research are expected to contribute to the development of highly productive tomato breeding by introducing the high photosynthetic capacity of wild tomatoes to cultivated tomatoes.
