Testing models for the leaf economics spectrum with leaf and whole-plant traits in Arabidopsis thaliana.

Blonder B, Vasseur F, Violle C, Shipley B, Enquist BJ, Vile D - AoB Plants (2015)

Bottom Line: We use structural equation modelling applied to multiple ecotypes, recombinant inbred lines, near isogenic lines and vascular patterning mutants of Arabidopsis thaliana that express LES trait variation.We show that a wide variation in multiple functional traits recapitulates the LES at the whole-plant scale.Venation networks remain a key hypothesis for the origin of the LES, but simpler explanations also cannot be ruled out.

Pairwise correlations between LES traits, VD and LDMC for multiple A. thaliana genotypes. Grey points indicate individual leaves; black points, genotype means. Symbols indicate genotype category: circles, mutants; triangles, NILs; pluses, RILs, crosses, ecotypes. Pairwise relationships between traits are shown, with lines indicating standard major axis regressions on genotype-mean log10-transformed data. Solid lines, P < 0.05; dashed lines, not significant. Regression statistics are shown in the lower panel for each pairwise relationship.

PLV049F2: Pairwise correlations between LES traits, VD and LDMC for multiple A. thaliana genotypes. Grey points indicate individual leaves; black points, genotype means. Symbols indicate genotype category: circles, mutants; triangles, NILs; pluses, RILs, crosses, ecotypes. Pairwise relationships between traits are shown, with lines indicating standard major axis regressions on genotype-mean log10-transformed data. Solid lines, P < 0.05; dashed lines, not significant. Regression statistics are shown in the lower panel for each pairwise relationship.

Mentions: We first assessed correlations between LES traits. Consistent with a previous demonstration (Vasseur et al. 2012), LES correlations between Am, LL, LMA and Nm were found across genotypes (Fig. 2). All pairwise correlations between these genotype-mean values were significant (standard major axis regressions, all P < 0.05, R2 > 0.31), with signs the same as those described by the interspecific LES (Wright et al. 2004).Figure 2.
