“…In addition to ethylene, other hormones and signaling substances, such as auxin and nitric oxide (NO), have been involved in the up-regulation of Fe and P acquisition genes [3,4,29,68,[75][76][77][78][79][80][81]. In both deficiencies, the activating effect of auxin, ethylene and NO depend on the Fe or P status of the plants [68,69,75,76], which suggests the existence of additional Fe-and P-related signals acting in conjunction with ethylene, auxin and NO [82].…”

“…The formation of proteoid roots, as well as the expression of the LaSCR1 and LaSCR2 genes, which are crucial for the formation of this type of roots, were induced after the application of GSNO (S-nitrosoglutathione), a NO donor, to Fe-and P-sufficient lupine plants [80]. Likewise, both the expression of the aforementioned genes and the formation of proteoid roots were inhibited after the application of cPTIO (2-4-carboxyphenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide), a NO scavenger, under P, Fe or P and Fe deficiency conditions [80]. P and Fe deficiencies not only share the same activating signals in their respective responses, but also repressive ones.…”

Similarities and Differences in the Acquisition of Fe and P by Dicot Plants

This review deals with two essential plant mineral nutrients, iron (Fe) and phosphorus (P); the acquisition of both has important environmental and economic implications. Both elements are abundant in soils but are scarcely available to plants. To prevent deficiency, dicot plants develop physiological and morphological responses in their roots to specifically acquire Fe or P. Hormones and signalling substances, like ethylene, auxin and nitric oxide (NO), are involved in the activation of nutrient-deficiency responses. The existence of common inducers suggests that they must act in conjunction with nutrient-specific signals in order to develop nutrient-specific deficiency responses. There is evidence suggesting that P-or Fe-related phloem signals could interact with ethylene and NO to confer specificity to the responses to Fe-or P-deficiency, avoiding their induction when ethylene and NO increase due to other nutrient deficiency or stress. The mechanisms responsible for such interaction are not clearly determined, and thus, the regulatory networks that allow or prevent cross talk between P and Fe deficiency responses remain obscure. Here, fragmented information is drawn together to provide a clearer overview of the mechanisms and molecular players involved in the regulation of the responses to Fe or P deficiency and their interactions.

“…No formation of cluster roots occurs with addition of the donor under P-sufficient conditions, indicating that the nitric oxide signal has to be associated with a P-starvation signal to become active. Nitric oxide is also involved in cluster-root formation induced by iron (Fe) deficiency [43].Cytokinins are important components in regulating lateral root formation, and strong antagonists of auxin-mediated cluster-root formation [30,32]. The presence of cytokinins in the growth medium strongly suppresses cluster-root formation [29].…”

Mycorrhizas play a pivotal role in phosphorus (P) acquisition of plant roots, by enhancing the soil volume that can be explored. Non-mycorrhizal plant species typically occur either in relatively fertile soil or on soil with a very low P availability, where there is insufficient P in the soil solution for mycorrhizal hyphae to be effective. Soils with a very low P availability are either old and severely weathered or relatively young with high concentrations of oxides and hydroxides of aluminium and iron that sorb P. In such soils, cluster roots and other specialised roots that release P-mobilising carboxylates are more effective than mycorrhizas. Cluster roots are ephemeral structures that release carboxylates in an exudative burst. The carboxylates mobilise sparingly-available sources of soil P. The relative investment of biomass in cluster roots and the amount of carboxylates that are released during the exudative burst differ between species on severely weathered soils with a low total P concentration and species on young soils with high total P concentrations but low P availability. Taking a modelling approach, we explore how the optimal cluster-root strategy depends on soil characteristics, thus offering insights for plant breeders interested in developing crop plants with optimal cluster-root strategies.

+ is a major source of inorganic nitrogen for rice (Oryza sativa), and NH 4 + is known to stimulate the uptake of phosphorus (P). However, it is unclear whether NH 4 + can also stimulate P remobilization when rice is grown under P-deficient conditions. In this study, we use the two rice cultivars 'Nipponbare' and 'Kasalath' that differ in their cell wall P reutilization, to demonstrate that NH 4 + positively regulates the pectin content and activity of pectin methylesterase in root cell walls under 2P conditions, thereby remobilizing more P from the cell wall and increasing soluble P in roots and shoots. Interestingly, our results show that more NO (nitric oxide) was produced in the rice root when NH 4 + was applied as the sole nitrogen source compared with the NO 3 2. The effect of NO on the reutilization of P from the cell walls was further demonstrated through the application of the NO donor SNP (sodium nitroprusside) and c-PTIO (NO scavenger 2-(4-carboxyphenyl)-4, 4, 5, 5-tetramethylimidazoline-1-oxyl-3-oxide). What's more, the P-transporter gene OsPT2 is up-regulated under NH 4 + supplementation and is therefore involved in the stimulated P remobilization. In conclusion, our data provide novel (to our knowledge) insight into the regulatory mechanism by which NH 4 + stimulates Pi reutilization in cell walls of rice.
