“…Se reconoce que el gradiente de modernización (Figura 2, abajo) repercute negativamente en la biodiversidad microbiana de los agroecosistemas (Lupatini, Korthals, de Hollander, Janssens & Kuramae, 2017;Martínez-Romero, Noyola, Taype, Martínez-Romero & Dávila, 2020). Desde los años 90, se ha reportado que existe una menor microbiodiversidad en hábitats modificados Vol.…”

“…La domesticación de las plantas también ha ocasionado que estas recluten microorganismos distintos a los de sus ancestros (Martínez-Romero et al, 2020). Por ejemplo, el microbioma de la rizosfera de dos variedades de frijol, una silvestre y otra domesticada, presenta cambios asociados a la estructura de sus raíces (Pérez-Jaramillo et al, 2017).…”

La microbiología agrícola busca reemplazar a los agroquímicos por microorganismos o sus productos como agentes de control biológico, debido a que el uso de tecnologías de la revolución verde tiene efectos negativos sobre el ambiente, los productores y sus familias, los consumidores y la salud de los cultivos. Sin embargo, el conocimiento actual acerca de las interacciones benéficas planta-bacteria en ambientes complejos es limitado e insuficiente, para lograr el éxito esperado de los productos biológicos. Las milpas son agroecosistemas tradicionales donde se cultivan diversas variedades de maíz nativo con otras especies asociadas; no se utiliza riego, ni labranza y aunque su aplicación va en aumento, comúnmente no se utilizan agroquímicos; por esto, la milpa representa una fuente de conocimiento sobre prácticas sustentables. Recientemente, se han descrito cambios en las comunidades microbianas de los sistemas agrícolas a causa de la modernización y a la domesticación de las plantas. En la milpa, también se han identificado interacciones benéficas planta-bacteria que parecen haberse perdido en los cultivos modernos. En esta revisión, discutimos las estrategias clásicas y modernas de la microbiología agrícola que pueden ser aplicadas en el estudio de la milpa. El establecimiento de la milpa como modelo de estudio de las interacciones planta-bacteria puede resultar en la generación del conocimiento necesario para disminuir el uso de agroquímicos en los sistemas agrícolas modernos, así como evitar su creciente uso en las milpas.

“…Thus, symbiotic interactions are undoubtedly a crucial feature for all life forms. In particular, interactions between microorganisms and larger animals are now gaining interest in transdisciplinary research given the implications not only for agriculture, sustainable environments and global warming, but also for human health, from metabolic control to cancer and cardiovascular disease to psychiatry (Cavicchioli et al, 2019;Cho & Blaser, 2012;Cryan et al, 2020;Martínez-Romero et al, 2020).…”

All life on earth is intrinsically linked. At the very foundation of everyevolutionary interaction are microorganisms; integral components in thecomposition of both organisms and ecosystems. This perspectivechallenges the traditional conception of monogenetic biologicalindividuals, suggesting living beings are actually composite multi-speciescomplexes; holobionts. In the present article, we introduce the conceptof the holobiont mind; a biogenic conception of cognition. Wefurthermore expand on the idea of the mind as the emerging product ofmulti-genomic morphology of a composite agent, in ever changinginteraction with its ecological niche. We briefly review recent evidence onthe Brain-Gut-Microbiome axis and the Microbiome of the BuiltEnvironment in order to provide a bridge between the Holobiont Mindand the 4E approach to Cognition, two complementary lines of evidencethat have not been linked before, opening novel venues for research withdirect impact on health and disease.

“…in the animal gut and in plant roots (Turner et al, 2013;Hacquard et al, 2015). However, how this can imply coevolution and consideration of the holobiont as a unit of selection is still hotly debated (Moran and Sloan, 2015;Koskella and Bergelson, 2020). Indeed, the host-associated microbiota is not fully stable, and rapid variation in its composition and functioning can take place.…”

“…Classically, plant domestication has involved selection of varieties on the basis of phenotypic features relevant to the farmer and adapted to the agricultural practices, without considering the associated microbiota. Since crops mostly rely on external inputs (e.g., fertilizers) and not on associated microbes, a decrease of microbiota diversity has been observed (Escudero-Martinez and Bulgarelli, 2019;Martínez-Romero et al, 2020), reducing the buffering effect offered by a diverse holobiont. For instance, in legumes it has been demonstrated that in the wild-growing varieties the symbiotic potential is usually higher than in commercial ones (Provorov and Tikhonovich, 2003).…”

Mutualistic interactions have great importance in ecology, with genetic information that takes shape through interactions within the symbiotic partners and between the partners and the environment. It is known that variation of the host-associated microbiome contributes to buffer adaptation challenges of the host’s physiology when facing varying environmental conditions. In agriculture, pivotal examples are symbiotic nitrogen-fixing rhizobia, known to contribute greatly to host (legume plants) adaptation and host productivity. A holistic view of increasing crop yield and resistance to biotic and abiotic stresses is that of microbiome engineering, the exploitation of a host-associated microbiome through its rationally designed manipulation with synthetic microbial communities. However, several studies highlighted that the expression of the desired phenotype in the host resides in species-specific, even genotype-specific interactions between the symbiotic partners. Consequently, there is a need to dissect such an intimate level of interaction, aiming to identify the main genetic components in both partners playing a role in symbiotic differences/host preferences. In the present paper, while briefly reviewing the knowledge and the challenges in plant–microbe interaction and rhizobial studies, we aim to promote research on genotype x genotype interaction between rhizobia and host plants for a rational design of synthetic symbiotic nitrogen-fixing microbial communities to be used for sustainably improving leguminous plants yield.
