Retarded growth of leaf and root organs in nsn1. a Eight-day-old seedlings of wild type and nsn1, showing reduced size of cotyledons and late initiation of the first leaf in nsn1. Scale bar: 1 mm. b Statistical analysis of cotyledon area of 8-day-old seedlings. c Twenty-one-day-old wild type and nsn1 plants. d Leaf area analysis of the fifth leaf from 21-day-old plants. e Ten-day-old seedlings grown on MS medium showing retarded root growth in nsn1 as compared with the wild type. f Statistical analysis of the primary root length of 10-day-old seedlings. For the statistical analysis, three biological replicates were conducted with 15 plants measured for each experiment
