Phenotypic Characterization of Wild-Type and slm1 Plants of M. truncatula

GenotypeTerminal Leaflet Length (cm)Terminal Leaflet Width (cm)Petiole Length (cm)Rachis Length (cm)
Wild type1.80 ± 0.202.13 ± 0.126.53 ± 0.580.95 ± 0.13
slm1-11.47 ± 0.17*2.24 ± 0.157.41 ± 0.43*1.64 ± 0.15*

  • Leaflet length was measured from tip to base of the terminal leaflet. Leaflet width was measured from margin to margin of the terminal leaflet. Petiole and rachis length were measured on the first fully expanded trifoliate of 8-week-old plants. Numbers are presented as mean ± sd. The number of observations in each mean is 35. Asterisks indicate that the differences between the wild type and slm1 are statistically significant at P < 0.05.
