“…In the absence of the AMF R. clarus , we observed nodulation of P. gonoacantha , which is contrary to the report of Jesus et al (), but in accordance with Júnior et al (). However, on non‐mycorrhizal plants, nodules were non‐fixing and did not promote plant growth, except for those obtained with Pa. nodosa STM 7144 for which inoculation had an impact on plant dry weight, although no nitrogenase activity (ARA) could be detected (Figure b,c).…”

“…In our more controlled conditions in France, these degrading communities might be absent, and thus inefficient nodules were maintained for longer periods. Interestingly, over shorter periods (11 weeks) in greenhouses in Brazil, but under more controlled conditions with plants cultivated in Magenta pots, Júnior et al () only obtained amorphous nodules on P. gonoacantha , in the absence of AMF.…”

“…and Piptadenia paniculata Benth., have the property of being dependent on arbuscular mycorrhization to form nitrogen‐fixing nodules. In more controlled conditions, Júnior, Jesus, Lisboa, Berbarac, and Faria () showed that, in the absence of AMF, only inefficient, amorphous nodules were formed. Co‐inoculation with AMF allowed these authors to observe plant growth promotion with contrasting responses between different fungal and rhizobial strains.…”

Tripartite interactions between legumes and their root symbionts (rhizobia and arbuscular mycorrhizal fungi, AMF) are poorly understood, although it is well established that only specific combinations of symbionts lead to optimal plant growth. A classic example in which to investigate such interactions is the Brazilian legume tree Piptadenia gonoacantha (Caesalpinioideae), for which efficient nodulation has been described as dependent on the presence of AMF symbiosis. In this study, we compared the nodulation behaviour of several rhizobial strains with or without AMF inoculation, and performed analyses on nodulation, nodule cytology, N-fixing efficiency, and plant growth response. Nodulation of P. gonoacantha does not rely on the presence of AMF, but mycorrhization was rhizobial strain-dependent, and nodule effectiveness and plant growth were dependent on the presence of specific combinations of rhizobial strains and AMF. The co-occurrence of both symbionts within efficient nodules and the differentiation of bacteroids within nodule cells were also demonstrated. Novel close interactions and interdependency for the establishment and/or functioning of these symbioses were also revealed in Piptadenia, thanks to immunocytochemical analyses. These data are discussed in terms of the evolutionary position of the newly circumscribed mimosoid clade within the Caesalpinioid subfamily and its relative proximity to non-nodulated (but AMF-associated) basal subfamilies.

“…Similarly, when studying the associative effect of Rhizobium and PSB on chickpea yield, Alagawadi and Gaur (1988) reported an increased bioavailable P fraction, N uptake, and yield as a response to co-application of both strains under superphosphate fertilization, thus suggesting that co-applying nutrient-supplying microbes could halve chemical N input. On another hand, some plant species like Piptadenia gonoacantha cannot nodulate in the absence of mycorrhizal colonization and when P is a limiting factor and that AMF are likely to be involved in the BNF process as recently demonstrated by Júnior et al (2017) .…”

Soil Microbial Resources for Improving Fertilizers Efficiency in an Integrated Plant Nutrient Management System

Tomorrow’s agriculture, challenged by increasing global demand for food, scarcity of arable lands, and resources alongside multiple environment pressures, needs to be managed smartly through sustainable and eco-efficient approaches. Modern agriculture has to be more productive, sustainable, and environmentally friendly. While macronutrients such as nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) supplied by mineral fertilizers are vital to crop production, agriculturally beneficial microorganisms may also contribute directly (i.e., biological N2 fixation, P solubilization, and phytohormone production, etc.) or indirectly (i.e., antimicrobial compounds biosynthesis and elicitation of induced systemic resistance, etc.) to crop improvement and fertilizers efficiency. Microbial-based bioformulations that increase plant performance are greatly needed, and in particular bioformulations that exhibit complementary and synergistic effects with mineral fertilization. Such an integrated soil fertility management strategy has been demonstrated through several controlled and non-controlled experiments, but more efforts have to be made in order to thoroughly understand the multiple functions of beneficial microorganisms within the soil microbial community itself and in interaction with plants and mineral resources. In fact, the combined usage of microbial [i.e., beneficial microorganisms: N2-fixing (NF), P-solubilizing, and P mobilizing, etc.] and mineral resources is an emerging research area that aims to design and develop efficient microbial formulations which are highly compatible with mineral inputs, with positive impacts on both crops and environment. This novel approach is likely to be of a global interest, especially in most N- and P-deficient agro-ecosystems. In this review, we report on the importance of NF bacteria and P solubilizing/mobilizing microbes as well as their interactions with mineral P fertilization in improving crop productivity and fertilizers efficiency. In addition, we shed light on the interactive and synergistic effects that may occur within multi-trophic interactions involving those two microbial groups and positive consequences on plant mineral uptake, crop productivity, and resiliency to environmental constraints. Improving use of mineral nutrients is a must to securing higher yield and productivity in a sustainable manner, therefore continuously designing, developing and testing innovative integrated plant nutrient management systems based on relevant biological resources (crops and microorganisms) is highly required.

“…Cabe destacar que la colonización fúngica con Bacteriano 2629 superó al testigo fertilizado (Cuadro 4). Este fenómeno de incremento en la colonización natural de HMA, a través de la inoculación de rizobacterias, aunque no está esclarecido, también fue reportado en la leguminosa Piptadenia gonoacantha con cepas de rizobacterias f ijadoras de nitrógeno (Junior et al, 2017).…”

Los inoculantes microbianos poseen gran importancia ecológica y económica en la agricultura. Se evaluó la efectividad agrobiológica de la inoculación de cepas microbianas en sorgo (D-47) cultivado en condiciones de riego y temporal. Fueron seis cepas experimentales de hongos micorrízicos arbusculares [3 (Funneliformis mosseae), 20 (Gigaspora albida), 32 (F. mosseae), 35 (F. mosseae), 39 (F. mosseae) y 55 (Gigaspora albida)], un consorcio de bacterias promotoras de crecimiento [Pseudomonas spp. (Bacteriano 2709)] (Ba), micorriza arbuscular INIFAP (Rhizophagus intraradices) (M) y testigo fertilizado (TF), con dosis de 60-40-00 y 120-40-00, para temporal y riego, respectivamente. Se midió clorof ila (SPAD), nitrógeno (N), fósforo (P), hierro (Fe) y zinc (Zn) foliar, biomasas foliar y radical, colonización micorrízica y rendimiento de grano. Las cepas microbianas influyeron de forma diferente en las características de sorgo sembrado en los agroambientes. En general se observó mejor respuesta del sorgo en la condición de riego. El contenido de Zn, la colonización micorrízica y biomasa radical, no fueron influenciados por la condición de humedad. En riego, los mayores índices de clorof ila fueron con TF y M; en la absorción de N destacaron TF, M y las cepas 3 y 32; los mayores valores de P se observaron con la cepa 35; para Fe sobresalió la cepa 32. Así mismo, el consorcio Bacteriano 2709 incrementó el Zn, mientras que en temporal fue la cepa 39. La mayor colonización se registró en M y cepas 55, 39 y 35. En rendimiento de grano, las cepas 39, 3 y M, fueron competitivas con TF y superaron al resto de los tratamientos. Los resultados demostraron que la expresión del potencial de los inoculantes microbianos en la nutrición y rendimiento de sorgo, variaron en función a la cepa utilizada y a la condición de riego y temporal.
