“…These genera were also found in previous studies on E. ulmoid es ( Dong et al, 2020 , 2021a ) and are beneficial microorganisms with potential ecological functions for medicinal plants ( Quijada et al, 2018 ; Asaf et al, 2020 ; Webster et al, 2020 ). Highly abundant unique bacteria of the rhizosphere soil samples included Bacteroidia, Clostridiales, Saccharibacillus , Spirochaeta , and Erysipelotrichaceae , which have specific selective effects on the soil, predominantly exist in the soil, and play an important role in geo-biological-chemical circulation ( Wilms et al, 2006 ; Namirimu et al, 2019 ). Most of the bacteria unique to the bark are those with relatively older evolutionary status, such as the Planctomycetes, which are important for the nitrogen cycle ( Cavalier-Smith, 2002 ).…”

Medicinal plants are inhabited by diverse microbes in every compartment, and which play an essential role in host growth and development, nutrient absorption, synthesis of secondary metabolites, and resistance to biological and abiotic stress. However, the ecological processes that manage microbiota assembly and the phenotypic and metabolic characteristics of the core microbiota of Eucommia ulmoides remain poorly explored. Here, we systematically evaluated the effects of genotypes, compartment niches, and environmental conditions (climate, soil nutrition, and secondary metabolites) on the assembly of rhizosphere soil and bark associated bacterial communities. In addition, phenotypic and metabolic characteristics of E. ulmoides core microbiota, and their relationship with dominant taxa, rare taxa, and pharmacologically active compounds were deciphered. Results suggested that microbiota assembly along the two compartments were predominantly shaped by the environment (especially pH, relative humidity, and geniposide acid) and not by host genotype or compartment niche. There were 690 shared genera in the rhizosphere soil and bark, and the bark microbiota was mainly derived from rhizosphere soil. Core microbiota of E. ulmoides was a highly interactive “hub” microbes connecting dominant and rare taxa, and its phenotypic characteristics had a selective effect on compartment niches. Metabolic functions of the core microbiota included ammonia oxidation, nitrogen fixation, and polyhydroxybutyrate storage, which are closely related to plant growth or metabolism. Moreover, some core taxa were also significantly correlated with three active compounds. These findings provide an important scientific basis for sustainable agricultural management based on the precise regulation of the rhizosphere soil and bark microbiota of E. ulmoides.

“…Cuando son sometidas a factores de estrés, como cambios en el pH o salinidad (por condiciones climáticas variables), los mecanismos de equilibrio homeostático que presentan las células bacterianas, como ser la modificación de componentes lipídicos de membrana o la producción de solutos compatibles a fin de disminuir la desregulación salina; podrían explicar, en principio, la presencia de cepas con características de crecimiento ácido en suelos salinos-alcalinos (Papadimitriou et al, 2016;Liu, Chan, Chen, Solem y pág. 90 Jensen, Namirimu , Kim y Zo, 2019).…”

<p>La variabilidad climática local constituye uno de los factores naturales más significativos en los procesos y dinámicas que ocurren en un determinado paisaje. Por esta razón, es importante conocer los montos pluviométricos y su distribución temporal, como así también la recurrencia y magnitud de eventos de inundación y sequía. Por otra parte, el conocimiento de la presencia de bacterias lácticas en función de las condiciones ambientales es de sumo interés, tanto para la producción de quesos artesanales como industriales. En este marco, el objetivo de este trabajo fue relacionar la presencia de bacterias lácticas autóctonas en ambientes naturales y las características del paisaje asociadas a la variabilidad climática local. Los resultados permitieron demostrar que la situación ambiental al momento del muestreo, se relacionó directamente con la capacidad de crecimiento de las cepas de bacterias lácticas bajo estudio en condiciones <em>in vitro</em>.</p>
