| 1 | Arabidopsis NLP7 improves nitrogen use efficiency and yield in cotton显示文摘Background: Nitrogen(N) is a required macronutrient for cotton growth and productivity. Excessive N fertilizers are applied in agriculture for crop yield maximization, which also generates environmental pollution. Improving crop N use efficiency(NUE) is the most economical and desirable way of reducing fertilizer application and environmental pollution. NUE has been an important issue in cotton. So far there is no report on cotton NUE improvement via transgenic approach. Nin-like proteins(NLP) are transcription factors regulating NUE. We previously demonstrated that At NLP7 improved NUE and biomass when overexpressed in Arabidopsis. However, it is not known whether At NLP7 can be used to improve NUE in crops.Results: To test the feasibility, we expressed At NLP7 in cotton and evaluated NUE and yield of the transgenic cotton in the field. Transgenic cotton showed improved NUE and yield under both low and high N conditions. In addition, plant biomass, amount of absorbed N, N contents, activities of N-assimilating enzymes, and the expression of N-related marker genes were significantly increased in transgenic cotton compared with the wild type control, suggesting that At NLP7 enhances NUE in cotton.Conclusion: Together, our results demonstrate that At NLP7 is a promising candidate to improve NUE and yield in cotton. | JAN Sami Ullah LIAQAT Ayesha ZHU Yonghong LI Jing ZHANG Huangyang ABDALLA Mohnad WU Jie XIANG Chengbin WU Shenjie ALFATIH Alamin | 2022 | Journal of Cotton Research2022，5，1： | 0 |
