| Research Abstract |
Arabidopsis FOX (Full-length cDNA over-expressor genes) agrobacterium librarys were transformed into established AtHAK5 promoter::luciferase Arabidopsis plants. These AtHAK5 promoter::luciferase plants with FOX library have been screened and more than 200 candidate transgenic plants that have higher luciferase activity under full nutrient condition have been isolated. Among them, fifteen lines were analyzed to determine which gene is overexpressed, and some candidates were analyzed for their expression in response to nutrient deficiency. The overexpression plants and knockout plants of WRKY TF were obtained. The overexpression plants showed increased tolerance to potassium deficient condition.
