Genetic approaches for improvement of the crop potassium acquisition and utilization efficiency
2015
Wang, Yi | Wu, Wei-Hua
Potassium (K) is one of the essential macronutrients for higher plants, not only important for plant growth and development, but also crucial for crop yield and quality. The deficiency in K in large areas of arable land worldwide has become a limitation for sustainable development of agriculture, and threatens the world food security. Along with the increased limitation of K fertilizer supply, the genetic improvement of K utilization efficiency (KUE) of crop plants may become a feasible way to solve the problem. K nutrition depends on an underlying relationship with metabolic regulation which together influence crop yield, quality and responses to environmental stress. Manipulation of root architecture together with K transport and distribution within the plant offer great potential to improve KUE.
