Abstract
Potassium (K) is an essential macronutrient for plant growth and development and influences yield and quality of agricultural crops. Maize (Zea mays) is one of the most widely distributed crops worldwide. In China, although maize consumes a large amount of K fertilizer, the K uptake/utilization efficiency (KUE) of maize cultivars is relatively low. Elucidation of KUE mechanisms and development of maize cultivars with higher KUE are needed. Maize KUE is determined by K+ uptake, transport, and remobilization, which depend on a variety of K+ channels and transporters. We review basic information about K+ channels and transporters in maize, their functions and regulation, and the roles of K+ in nitrogen transport, sugar transport, and salt tolerance. We discuss challenges and prospects for maize KUE improvement.

期刊介绍:
The major aims of The Crop Journal are to report recent progresses in crop sciences including crop genetics, breeding, agronomy, crop physiology, germplasm resources, grain chemistry, grain storage and processing, crop management practices, crop biotechnology, and biomathematics.
The regular columns of the journal are Original Research Articles, Reviews, and Research Notes. The strict peer-review procedure will guarantee the academic level and raise the reputation of the journal. The readership of the journal is for crop science researchers, students of agricultural colleges and universities, and persons with similar academic levels.
