Special Issue Information

Dear Colleagues,

With the world's population expected to reach approximately 9 billion by 2050, food production needs to increase by 70 percent. Mineral nutrition deficiency is one of the most important agronomical problems. Current production systems are based on the use of high-yielding varieties and the application of large quantities of agrochemicals, which causes major environmental problems. One more sustainable alternative to the use of synthetic fertilizers is the use of beneficial microorganisms. To cope with nutrient deficiencies, plants develop morphological and physiological responses, mainly in their roots, aimed to facilitate nutrient acquisition. In the last years, it has been found that some rhizosphere microbes can induce physiological and morphological responses in roots of plants similar to the ones induced by plants under nutrient deficiencies. Elucidating the mode of action and main nodes of interconnection between rhizosphere microbes and nutrient deficiency response mechanisms is critical for optimizing the use of plant mutualistic microbes in agriculture.

Papers submitted to this article collection must report new results and the latest findings related to the roles of rhizosphere microbes on mineral nutrition in crops.

We particularly welcome manuscripts dealing with the following topics:

- Molecular, physiological or morphological mechanisms of action of microbes able to induce responses aimed to facilitate nutrient acquisition.

- Interaction of microbes with hormones implicated in nutrient deficiency responses regulation.

- Effects of applying individual microbial species or consortia of different microbial species.

All forms of submissions (i.e., original research papers, Mini Reviews, Methods, Perspectives, Hypothesis and Theories, and Opinion Articles) are welcome.

Iron (Fe) deficiency is among the most important agronomical concerns under alkaline conditions. Bicarbonate is considered an important factor causing Fe deficiency in dicot plants, mainly on calcareous soils. Current production systems are based on the use of high-yielding varieties and the application of large quantities of agrochemicals, which can cause major environmental problems. The use of beneficial rhizosphere microorganisms is considered a relevant sustainable alternative to synthetic fertilizers. The main purpose of this work has been to analyze the impact of the inoculation of tomato (Solanum lycopersicum L.) seedlings with the WCS417 strain of Pseudomonas simiae, in the presence or absence of bicarbonate, on plant growth and other physiological parameters. To conduct this research, three different inoculation methods were implemented: root immersion, foliar application, and substrate inoculation by irrigation. The results obtained show the ability of the P. simiae WCS417 strain to induce medium acidification in the presence of bicarbonate to increase the SPAD index and to improve the growth and development of the tomato plants in calcareous conditions provoked by the presence of bicarbonate, which indicates that this bacteria strain could have a great potential as an Fe biofertilizer.

Plant-essential phosphorus (P) is a sparingly available mineral in soils. Phosphorus fertilizers—produced by the transformation of insoluble to soluble phosphates—are thus applied to agroecosystems. With advancements in commercial agriculture, crops have been increasingly adapted to grow in fertile environments. Wild crop relatives, however, are adapted to grow in unfertilized soils. In response to these two conditions of P bioavailability (fertilized agroecosystems and unfertilized natural soils), domesticated crops and wild species employ different strategies to grow and develop. It is essential to understand strategies related to P acquisition that may have been lost to domestication, and here we present, for the first time, that across species, modern cultivars engage in physical (i.e., root morphological) mechanisms while their wild relatives promote ecological (i.e., root-microbial) mechanisms. Domesticated crops showcase shallower root system architecture and engage in topsoil foraging to acquire P from the nutrient-stratified environments common to fertilized agroecosystems. Wild species associate with P-cycling bacteria and AM fungi. This divergence in P recovery strategies is a novel delineation of current research that has implications for enhancing agricultural sustainability. By identifying the traits related to P recovery that have been lost to domestication, we can strengthen the P recovery responses by modern crops and reduce P fertilization. Full article
