【Objective】 In this study, the chromosome localization of TaPHT2;1, a phosphate transporter gene in wheat, was determined by using Chinese spring(CS) and its chromosome-based ditelosimic lines of B genome. Moreover, the expression pattern of TaPHT2;1 as well as its relationship with plant dry matter production and P use efficiency was studied under high- and low-Pi conditions.【Method】The cultivar CS together with its chromosome-based ditelosimic lines of B genome as well as wheat cultivars with varied P use...
