“…This study was conducted to determine the effects of artificially decreased VPD on silver birch (Betula pendula Roth.) and hybrid aspen (Populus tremula L.×P. tremuloides Michx.) foliar metabolite and nutrient profiles in a unique free air humidity manipulation (FAHM) field experiment during the fourth season of humidity manipulation, in 2011. …”

“…High temperature (HT) and drought are both critical factors that constrain tree growth and survival under global climate change, but it is surprising that the transcriptomic reprogramming and physiological relays involved in the response to HT and/or drought remain unknown in woody plants. Thus, Populus simonii saplings were exposed to either ambient temperature or HT combined with sufficient watering or drought. …”

“…We labeled transported inorganic carbon, spanning reported xylem concentrations, with (13)C and then manipulated transpiration rates in the dark in order to vary the rates of inorganic carbon supply to cut leaves from Brassica napus and Populus deltoides. We used tunable diode laser absorbance spectroscopy to directly measure the rate of gross (13)CO(2) efflux, derived from inorganic carbon supplied from outside of the leaf, relative to gross (12)CO(2) efflux generated from leaf cells. …”

We discuss several appropriate experimental designs for extensive GWAS in a given undomesticated tree population, such as omics-wide association studies and high-throughput phenotyping technologies. …”

Additionally, the expression patterns of JrPAL3, JrPAL7, JrPAL9, and JrPAL2-1 showed that they had high expression in female and male flowers. …”
