Water relations are one the most difficult traits to phenotyp e due to the complex properties of soils\, rapidly changing soil/atmospher e water status and the interaction of drought with other stress factors. W e recently developed a general framework combining functional physiologica l phenotyping and functional mapping to bridge the phenotype-genotype gap. More recently\, we employed a physio-functional approach to study the who le-plant water relations and the underlying molecular mechanisms in soybea n and cowpea\, a water profligate and conservative legume crop\, respectiv ely. Continuous transpiration rate monitoring demonstrated that cowpea use d water more conservatively under earlier drought stages\, but tended to m aintain higher transpiration under prolonged drought. Interestingly\, we o bserved a soybean-specific transpiration rate increase accompanied by phas e shift under mild drought. Transcriptomic analysis suggested a dehydratio n avoidance mechanism of cowpea\, in which the VuHAI3 and VuTIP2 \;3 genes were suggested to be involved. Drought also differently affe cted clock gene expressions between species in a drought scenario-dependen t manner\, which in turn differentially perturbated rhythm of downstream g enes. Gene network analysis identified a pair of negatively-correlated mod ules between species. Module hub genes\, including the ABA-degrading gene GmCYP707A4 and the trehalose-phosphatase/ synthase gene VuTPS9 were identified. Functional analyses verified< i> VuTPS9 as regulating transpiration and thus likely water use behaviors. These findings enable the drawing of a comp rehensive picture of the mechanisms underlying the profligate versus conse rvative water use strategies in legumes.
