Bottom Line: The field measurements showed that WUE of M. lutarioriparius in the semiarid location was significantly higher than that in the wet location.It was also found that the relatively high expression variation of the WUE-related genes was affected to a larger extent by environment than by genetic variation.The study demonstrates that transcriptome-wide correlation between physiological phenotypes and expression levels offers an effective means for identifying candidate genes involved in the adaptation to environmental changes.

Comparison of water use efficiencies (WUE) of M. lutarioriparius between two sites. The empty boxplot shows the mean value of WUE in Jiangxia of Hubei Province (JH) and the solid boxplot the mean value of WUE in Qingyang of Gansu Province (QG). The t test between the WUE values in JH and QG is examined and the result shows that the WUE value of M. lutarioriparius is significantly higher in QG than in JH (P <0.001).

Figure 2: Comparison of water use efficiencies (WUE) of M. lutarioriparius between two sites. The empty boxplot shows the mean value of WUE in Jiangxia of Hubei Province (JH) and the solid boxplot the mean value of WUE in Qingyang of Gansu Province (QG). The t test between the WUE values in JH and QG is examined and the result shows that the WUE value of M. lutarioriparius is significantly higher in QG than in JH (P <0.001).

Mentions: WUE ranged from 2.484 to 4.027 μmol mmol–1 in JH, while it ranged from 2.886 to 4.930 μmol mmol–1 in QG. The minimum value of WUE was lower in JH than in QG, and the maximum value of WUE showed the same pattern. In addition, the average WUE in JH and QG were 3.340 and 3.956 μmol mmol–1, respectively. In order to detect the differences of WUE between M. lutarioriparius individuals in JH and QG, an unpaired two-group Student’s t test analysis was carried out which showed that the WUE of M. lutarioriparius individuals was significantly higher in QG than those in JH (P <0.001; Fig. 2). The CO2 assimilation rate (A) and transpiration rate (E) were recorded for all individuals in both fields (see Supplementary Fig. S1 at JXB online).
