摘要： White clover (Trifolium repens L.) is an important pasture legume in many regions of the world. A commercial cultivar of white clover (cv. Patriot) was transformed with a Medicago truncatula L. transcription factor gene, WXP1, and a reporter gene, beta-glucuronidase (GUS). The WXP1 gene and the GUS gene were placed under control of the Arabidopsis CER6 promoter. GUS staining and cross-section analysis revealed the CER6 promoter directed constitutive expression in leaves and epidermis preferential expression in petioles of white clover. Independent transgenic WXP1 lines, empty vector and wild-type controls were subjected to drought stress treatment. The plants were characterised by measuring several physiological parameters including gas exchange, chlorophyll fluorescence, relative water content and leaf water potential. The WXP1 transgenic lines had higher net photosynthetic rates, higher efficiency of PSII, higher relative water content and leaf water potential under drought-stressed conditions. Consistent with the results from physiological analyses, the transgenic white clover plants carrying WXP1 showed improved tolerance to drought stress.
