The visual deficiency symptoms developing on plants constitute the ultimate manifestation of
suboptimal nutrient supply. In classical plant nutrition, these symptoms have been …

Background Suboptimal water and nutrient availability are primary constraints in global
agriculture. Root anatomy plays key roles in soil resource acquisition. In this article we …

Optimal plant development requires root uptake of 14 essential mineral elements from the
soil. Since the bioavailability of these nutrients underlies large variation in space and time …

In order to optimally establish their root systems, plants are endowed with several
mechanisms to use at distinct steps during their development. In this review, we zoom in on …

It is well known that glutamate (Glu), a neurotransmitter in human body, is a protein amino
acid. It plays a very important role in plant growth and development. Nowadays, Glu has …

Plant nitrogen (N), acquired mainly in the form of nitrate and ammonium from soil, dominates
growth and development, and high-yield crop production relies heavily on N fertilization. The …

Highlights•Root nitrate sensing is affected by rhizosphere pH and water availability.•Nitrate
transporters are involved in sensing cellular pH changes.•Root derived small mobile …

Nitrogen (N) is the most abundant mineral nutrient required by plants, and crop productivity
depends heavily on N fertilization in many soils. Production and application of N fertilizers …

The enzymatic controlled metabolic processes in cells occur at their optimized pH ranges,
therefore cellular pH homeostasis is fundamental for life. In plants, the nitrogen (N) source …
