“…The trial showed that, a decade later, a combination of a legume tree with a cardon cactus, while detrimental to the legume, significantly increased the chances of the cactus surviving and growing in degraded soil. (Moreno et al 2017). Recently, inoculation of Brachiaria spp.…”

Azospirillum is one of the most studied plant growth-promoting bacteria (PGPB); it represents a common model for plantbacterial interactions. While Azospirillum brasilense is the species that is most widely known, at least 22 species, including 17 firmly validated species, have been identified, isolated from agricultural soils as well as habitats as diverse as contaminated soils, fermented products, sulfide springs, and microbial fuel cells. Over the last 40 years, studies on Azospirillum-plant interactions have introduced a wide array of mechanisms to demonstrate the beneficial impacts of this bacterium on plant growth. Multiple phytohormones, plant regulators, nitrogen fixation, phosphate solubilization, a variety of small-sized molecules and enzymes, enhanced membrane activity, proliferation of the root system, enhanced water and mineral uptake, mitigation of environmental stressors, and competition against pathogens have been studied, leading to the concept of the Multiple Mechanisms Hypothesis. This hypothesis is based on the assumption that no single mechanism is involved in the promotion of plant growth; it posits that each case of inoculation entails a combination of a few or many mechanisms. Looking specifically at the vast amount of information about the stimulatory effect of phytohormones on root development and biological nitrogen fixation, the Efficient Nutrients Acquisition Hypothesis model is proposed. Due to the existence of extensive agriculture that covers an area of more than 60 million hectares of crops, such as soybeans, corn, and wheat, for which the bacterium has proven to have some agronomic efficiency, the commercial use of Azospirillum is widespread in South America, with over 100 products already in the market in Argentina, Brazil, and Uruguay. Studies on Azospirillum inoculation in several crops have shown positive and variable results, due in part to crop management practices and environmental conditions. The combined inoculation of legumes with rhizobia and Azospirillum (co-inoculation) has become an emerging agriculture practice in the last several years, mainly for soybeans, showing high reproducibility and efficiency under field conditions. This review also addresses the use of Azospirillum for purposes other than agriculture, such as the recovery of eroded soils or the bioremediation of contaminated soils. Furthermore, the synthetic mutualistic interaction of Azospirillum with green microalgae has been developed as a new and promising biotechnological application, extending its use beyond agriculture.

“…También, en un estudio en la selva estacionalmente seca de Yucatán, se encontró que una parte importante de los árboles especialistas de selva secundaria son leguminosas que tienen pulvinos en las hojas (Sanaphre-Villanueva et al 2016). Las especies leguminosas se han propuesto como especies clave para la restauración de ecosistemas áridos (ver Siddique et al 2008, Padilla et al 2009, Moreno et al 2017) porque su capacidad de fijar nitrógeno es un elemento fundamental para su desempeño (Reich et al 2009). Además, estas especies tienden a producir mayor biomasa aérea (Barchuk et al 2006), lo que permite la incorporación de mayor hojarasca al suelo.…”

Antecedentes: La selva estacionalmente seca se puede recuperar usando plantaciones de restauración. La selección de especies para las plantaciones depende de su desempeño exitoso en las condiciones adversas de los sitios degradados. Hipótesis: Las especies leguminosas de estados sucesionales tempranos muestran mayor sobrevivencia en sitios degradados. Especies de estudio: Doce especies de árboles nativos de la selva estacional. Sitio y años de estudio: Pastizales excluidos de la ganadería en Quilamula, Tlaquiltenango, Morelos, México durante 28 meses de julio del 2017 a octubre del 2019. Métodos: Plantaciones experimentales para las 12 especies (N = 1,080 plantas). Se registró la supervivencia en octubre del 2017, junio y octubre del 2018 y en octubre del 2019 Resultados: Las especies sucesionales tempranas mostraron mayor supervivencia (27 %) que las tardías (20 %). Las leguminosas mostraron mayor supervivencia (25 %) que las no-leguminosas (22 %). Las especies tempranas no-leguminosas y las tardías leguminosas presentaron una supervivencia similar y esta fue mayor (> 30 %) que la de las especies leguminosas tempranas (< 18 %). Conclusiones: Para asegurar el éxito de plantaciones de restauración y acelerar la velocidad de recuperación se sugiere sembrar mezclas de especies sucesionales tempranas (i.e., Dodonaea viscosa Jacq. y Leucaena leucocephala (Lam.) De Wit) y la mayor cantidad posible de especies sucesionales tardías, leguminosas y no-leguminosas.

“…Pajares and Bohannan (2016) explained about the nitrogen-fixing bacteria in tropical forest. Bashan et al (2012) and Moreno et al (2017) scientifically proved that the PGPB and native plant species enhanced plant growth and soil stability in degraded forest and desert soil. Bashan et al (2012) and Liu et al (2013) reported that these bacteria accelerated the development of plant shoots and roots, increased the number of branches, nutrients and improved the survival rate in different forest seedlings of Prosopis articulata, Parkinsonia microphylla, and Parkinsonia florida and Fraxinus americana, respectively.…”

Indigenous plant growth-promoting bacteria enhance plant growth, biomass, and nutrient uptake in degraded forest plants

2018

The present study was aimed to isolate indigenous plant growth-promoting bacteria (PGPB) from Nanmangalam reserve forest, India and to analyze their positive impact on nursery plant species. In total, 160 isolates were obtained from different nitrogen-free Media (LGI, JMV, NFB). Amongst these, 12 isolates were shown positive for 5-8% of ammonia production nif H positive and then isolates were further tested for their plant growth-promoting (PGP) activity. Based on their PGP activity, nine isolates were selected, and applied in nurseries of twelve native plant species, along with organic manure and inorganic fertilizer. All the isolates were shown positive effects when compared to control. In that, five of these bacterial isolates, sp. RRB2, RRAK5, subsp. subtilis RRD8, RRAK1, and RRAN2, enhanced biomass production in several trees.
