This study aimed to evaluate the intake and nutrient digestibility, water, and nitrogen balance of Santa In?es crossbred ewes under confinement receiving reductions in the water supply. Thirty-two Santa In?es crossbred ewes, at an average body weight of 32.2 ± 7.4 kg and age of 2.3 ± 0.99 years, were distributed in a completely randomized design, with four treatments, and eight animals per treatment, the treatments were 100%, 80%, 60%, and 40% of ad libitum water. Nutrient intake and digestibility, water and nitrogen balance, and perfor- mance were evaluated. The reductions in the water supply did not promote significant alterations, in the nutrient intake, or apparent digestibility of the animals (P > 0.05). A linear decreasing effect was observed for free water intake (P < 0.001), total water intake (P < 0.001), total urine output (P = 0.008), water excreted via urine (P = 0.006), water excreted via feces (P = 0.006), total water losses (P < 0.001), water absorbed (P < 0.001), and nitrogen excreted via feces (P = 0.002). The water and nitrogen balance and performance were not influenced by water offers (P > 0.05). It was concluded that water offers of up to 40% of ad libitum intake, do not promote negative effects on intake and apparent nutrient digestibility, mineral intake, nitrogen balance, and water balance in Santa In?es ewes. |

Low soil phosphorus (P) availability is a major constraint for crop production in tropical regions. The rice (Oryza sativa) proteinkinase,PHOSPHORUS-STARVATION TOLERANCE1 (OsPSTOL1), was previously shown to enhance P acquisition and grain yield in rice under P deficiency. We investigated the role of homologs of OsPSTOL1 in sorghum (Sorghum bicolor) performance under low P. Association mapping was undertaken in two sorghum association panels phenotyped for P uptake, root system morphology and architecture in hydroponics and grain yield and biomass accumulation under low-P conditions, in Brazil and/or in Mali. Root length and root surface area were positively correlated with grain yield under low P in the soil, emphasizing the importance of P acquisition efficiency in sorghum adaptation to low-P availability. SbPSTOL1 alleles reducing root diameter were associated with enhanced P uptake under low P in hydroponics, whereas Sb03g006765 and Sb03g0031680 alleles increasing root surface area also increased grain yield in a low-P soil. SbPSTOL1 genes colocalized with quantitative trait loci for traits underlying root morphology and dry weight accumulation under low P via linkage mapping. Consistent allelic effects for enhanced sorghum performance under low P between association panels, including enhanced grain yield under low P in the soil in Brazil, point toward a relatively stable role for Sb03g006765 across genetic backgrounds and environmental conditions. This study indicates that multiple SbPSTOL1 genes have a more general role in the root system, not only enhancing root morphology traits but also changing root system architecture, which leads to grain yield gain under low-P availability in the soil.
