Nitrate, Auxin and Cytokinin-A Trio to Tango

Nitrogen is an important macronutrient required for plant growth and development, thus directly impacting agricultural productivity. In recent years, numerous studies have shown that nitrogen-driven growth depends on pathways that control nitrate/nitrogen homeostasis and hormonal networks that act both locally and systemically to coordinate growth and development of plant organs. In this review, we will focus on recent advances in understanding the role of the plant hormones auxin and cytokinin and their crosstalk in nitrate-regulated growth and discuss the significance of novel findings and possible missing links.

Nitrogen is essential for plant growth and its availability directly affects agricultural productivity. Recent studies have revealed the important roles of hormones auxin and cytokinin in nitrate-regulated growth. This review discusses the recent advancements in understanding the crosstalk between auxin and cytokinin and their significance in nitrate-driven growth, highlighting possible missing links.
