Plant phosphorus (P)-use efficiency (PUE) is determined by a plant's capacity to produce yield (biomass or grain) per unit of P available to it. A plant can achieve a higher PUE by: (i) enhancing acquisition of P from the rhizosphere, called P-acquisition efficiency or external PUE; and/or (ii) enhancing utilisation of the acquired P towards ...

Nitrogen assimilation in plants: current status and future ...

N assimilation is a main process for N utilization in plants. NR, NiR, GS, GOGAT, and enzymes related to N assimilation are encoded by a small multigene family. Although a number of works have demonstrated their functions, the functions of each member is still not fully elucidated yet, especially for functions of ASN, GDH, and CPSase in crops ...

Potassium and phosphorus transport and signaling in …

Potassium transport and signaling in Arabidopsis. In root cells, after perception of external low K + stress, plants generate some signal molecules (e.g., Ca 2+, reactive oxygen species (ROS)) that regulate downstream K + channels and transporters at transcriptional and post-translational levels. The red dots represent Ca 2+ ions. AKT1, HAK5, and KUP7 are all involved in K + uptake.
