Soil sickness a severe problem in tobacco production, leading to soil-borne diseases and reduce in tobacco yield. This occurs as a result of the interaction between root exudates and rhizosphere microorganisms, which is however, little studied until now. By combining the field investigation and pot experiment, we found the output yield consistently decreased during the first 10 years of continuous cropping in a tobacco field, but increased at the 15th year (15Y). The root exudate and rhizosphere bacterial community was further analyzed to reveal the underlying mechanism of the suppressive soil formation. Root exudate of 15Y tobacco enriched in amino acids and derivatives, while depleted in the typical autotoxins including phenolic acids and alkaloids. This was correlated to the low microbial diversity in 15Y, but also the changes in community composition and topological properties of the co-occurrence network. Especially, the reduced autotoxins were associated with low Actinobacteria abundance, low network complexity and high network modularity, which significantly correlated with the recovered output yield in 15Y. This study revealed the coevolution of rhizosphere microbiota and root exudate as the soil domesticated by continuous cropping of tobacco, and indicated a potential role of the autotoxins and theirs effect on the microbial community in the formation of suppressive soil.

“…Recently it has been reported that cropping patterns such as monoculture, intercropping, and crop rotation exerted a strong effect on the rhizosphere microbiome assembly (Wu et al, 2020;Li et al, 2022;Zhou et al, 2023). For example, consecutive monoculture of blueberry, Chinese fir, and tobacco remarkably alter the assembly of microbial communities in the rhizosphere (Che et al; Chen J. et al; Wang P. et al).…”

“…Increasing evidence has shown that plant allelopathy, replant disease, and interspecific facilitation in intercropping systems are facilitated by the integrative effects of plant-microbe interactions mediated by root exudates (Li et al, 2020;Mwendwa et al, 2021;Xu et al, 2021;Zhou et al, 2023). Yang et al indicate that root exudates of Rehmannia glutinosa could stimulate the proliferation of Fusarium oxysporum, which alters the expression patterns of Leucine-rich repeat receptor-like protein kinases (RgLRRs), disorders the growth and development of R. glutinosa, and finally results in the formation of replant disease.…”

Editorial on the Research TopicRhizosphere interactions: root exudates and the rhizosphere microbiomeThe rhizosphere, a term introduced by Lorenz Hiltner in 1904, is defined as a thin layer of soil that surrounds and is influenced by plant roots (Philippot et al., 2013). It can be divided into several distinct zones, including the endorhizosphere, the rhizoplane, and the ectorhizosphere (Morgan et al., 2005). The rhizosphere is one of the key interfaces between plants and their environment, with intensive root-induced physical, chemical, and biological processes . It is also considered a hotspot for plantmicrobe interactions because plant roots release enormous amounts of photosynthetically fixed carbon into the surrounding soil. Root exudation typically creates a nutrient-rich rhizosphere microenvironment in which microbial activity is stimulated. Root exudates consist of a wide variety of primary and secondary compounds, including carbohydrates, amino acids, and organic acids, phenolics, flavonoids, auxins (Zhu et al., 2016). They provide a readily bioavailable supply of nutrients and energy for microbial growth and also act as a signaling messenger to shape the rhizosphere microbiome (Luo et al., 2020;Koprivova and Kopriva, 2022). The rhizosphere microbiome, referred to as the plant's second genome, plays a crucial role in plant growth and health (Berendsen et al., 2012). The rhizosphere is colonized by a huge number of microorganisms and invertebrates, which exert either positive, negative, or neutral effects on plant growth and fitness. In recent years, there has been a growing interest in exploring plant-microbe rhizosphere interactions, termed rhizosphere cross-talk, in natural and agricultural ecosystems.The number of records retrieved through Web of Science with keywords 'rhizosphere interactions' or 'plant-microbe interactions' or 'rhizosphere crosstalk' or 'plant-soil feedbacks' or 'rhizosphere microbiome' increased from 406 (1948406 ( -2000406 ( ) to 1924406 ( (2001406 ( -2010406 ( ) and then to 11,451 (2011406 ( -2023406 ( ) (data retrieved August 12, 2023. As a response to the importance of plant-microbiome rhizosphere interactions, we proposed the Research Topic "Rhizosphere Interactions: Root Exudates and Rhizosphere Microbiome".

“…Allelopathy is a significant factor influencing plant interactions during intercropping. This is a biological phenomenon in which plants release bioactive compounds (allelochemicals) that affect the growth, development, and physiological processes of nearby plants. − The identification of allelochemicals in plants and their environments is crucial to understanding the interactions between plants and allelopathy. To date, a substantial number of allelochemicals have been studied and identified from various plant species.…”
