| Research Abstract |
Quantitative trait loci (QTL) for plant architecture, which could have a large impact on light capture efficiency and yield, were detected in tomatoes. Of these QTLs, QTL for canopy size was clustered with QTLs for leaf length and drooping angle. Therefore, it is likely that the canopy size is dependent on both leaf size and leaf drooping angle. Furthermore, QTLs for shoot nitrogen concentration and leaf length were co-located with expression QTL (eQTL) for nitrate transporter. This suggested that nitrogen distribution within plants affects leaf development.
