Description
Summary:Knowledge of natural variation among ecotypes and recombinant inbred lines of Arabidopsis thaliana L. Heynh for season-long water-use efficiency (WUE, moles of carbon accumulated per mole of water used) is useful in the design of experiments to understand the genetic control of this phenomenon. Water-use efficiency among 31 container-grown Arabidopsis ecotypes ranged from a high of 2.40 to a low of 1.86 mg/g (grams of dry aerial biomass per gram of water used). Genetic variance for WUE was observed among 80 F, recombinant inbred lines (RILs) derived from a cross between the highest (Lip-0) by the lowest (Edi-0) ecotype. The heritability of WUE was calculated as 0.18 +/- 0.07. The mean WUE for the ten highest and ten lowest RILs was 2.42 and 1.05 mg/g, respectively. A significant difference was observed in the composition of stable isotopes of plant carbon (delta 13C) between the mean of the ten highest (-31.23 per thousand) and the mean of the ten lowest (-31.96 per thousand) RILs based on WUE. Characterization of the 80 RILs provides a structured population for further genetic and physiologic study of WUE
