"During ID-IV we reported that TE was closely related to the capacity\r\nto restrict transpiration under high vapor pressure deficit\r\n(VPD). Experiments were undertaken to evaluate other possible\r\nfactors influencing TE. Experiments across seasons varying\r\nin VPD conditions and across water regimes showed that\r\nmaize had a higher TE than sorghum and pearl millet. While\r\nC4 cereals should, theoretically, have similar TE, 100 years of\r\nbreeding in maize could be responsible for these differences,\r\npossibly from increased rates of carbon fixation deriving from\r\nselective pressure underincreased planting densities. These\r\nresults then open an opportunity to accelerate breeding in\r\nsorghum and pearl millet by specifically targeting the possible\r\nreasons for these differences (RUE, density “resistance”). Further\r\nexperimentation was undertaken in which ears and panicles\r\nwere severed from the plants and showed that TE was depressed\r\nin maize and sorghum, respectively, while it was not in\r\npearl millet, which produced many new tillers and nodal tillers.\r\nThis work then raised the question of source-sink relationship\r\nin setting carbon demand and then photosynthetic activity. Finally,\r\nTE assessed in C4 cereals, grown in four different soils\r\nand two different VPD seasons, showed large TE differences\r\namong soils during the high VPD season, with a degree of species-by-soil\r\ninteraction. We interpret these differences to be a\r\nconsequence of different hydraulic soil properties likely affecting\r\nthe transpiration response under high VPD. Results will be\r\ndiscussed with regard to breeding targets in “less-bred” crops\r\n(pearl millet, sorghum) and with regards to better understanding\r\nGxExM interactions."^^ .
