Extended Data Table 4 Results of linear mixed-effects models (LMMs) testing the effects of domestication and improvement on ecophysiological traits

From: Early human selection of crops’ wild progenitors explains the acquisitive physiology of modern cultivars

  1. Results of LMMs with domestication (Dom) or improvement (Imp) as dependent variable, using the experimental dataset. Accession nested within crop species was considered as random factor. The table shows the Fd.f. value and significance of analysis of variance (ANOVA) tests. Significant values (P < 0.05) are highlighted in bold. The variance of the models explained by the fixed effects is given by the marginal pseudo-R2 (R2m), and the variance explained by both the fixed and random effects is given by the conditional pseudo-R2 (R2c). Abbreviations: Aarea, net photosynthetic rate per unit area; Amass, net photosynthetic rate per unit mass; gwv, stomatal conductance to water vapour; ETR, electron transport rate; Fv’/Fm’, photosystem II photochemical efficiency; iWUE, intrinsic water-use efficiency; SLA, specific leaf area; δ13C, 13C isotopic composition; δ15N, 15N isotopic composition; [Narea], area-based leaf N concentration; [Nmass], mass-based leaf N concentration; CN, leaf C to N ratio; and PNUE, photosynthetic N use efficiency.
