“…Faba bean intercropped with garlic obviously up-regulated the nodule numbers and nodules dry www.nature.com/scientificreports www.nature.com/scientificreports/ weight of faba bean 27 . Likewise, in the intercropping system of wheat and broad bean, the intercropped faba bean could up-regulate the nodule numbers, nodules dry weight and single nodule dry weight, suggesting that the intercropping could enhance the nodulation ability of faba bean 16 . The mentioned results may support that intercropping between alfalfa and triticale can enhance alfalfa's ability to compete for nitrogen, and the nodulation and N fixation ability of alfalfa are derived from low N. In this regard, the closer the intercropped roots of alfalfa and triticale interact, the better the nodulation and N fixation in alfalfa will exhibit.…”

Cereal/legume intercropping is likely to achieve the optimal exploitation of soil and atmospheric nitrogen (N) sources to maintain high production and quality levels with low N inputs, as an attempt to eliminate underlying environmental effects. Nevertheless, the extent of the effect of cereal/legume intercropping on nodulation and N fixation of intercropped legumes in root interaction requires extensive verification. In the present study, root interaction of alfalfa/triticale intercropping was simulated in pots with the use of root separation types (pot with no barrier (A-T), pot with nylon mesh barrier (NA-T), pot with plastic barrier (PA-T), and alfalfa alone (SA)) in pots. Moreover, the experiment was measured at a range of N levels (N 21 , N 210) and growing stages (branching, budding and initial flowering stages) in growth chamber. As alfalfa was growing, the total nodule number (TNN), effective nodule number (ENN) and nitrogenase activity (NA) of alfalfa with AT and other cropping systems more noticeably differed from each other at higher N levels, whereas their diversification was reduced at lower N levels. As alfalfa was growing continuously, fresh nodule weight per plant (PNW) and single fresh nodule weight (SNW) with AT and other cropping systems were amplified more significantly. The nodulation and N fixation ability under N 21 were more significant than those under N 210. Dry weight of plant per pot (TDW) and nitrogen accumulation of plant per pot (TNA) with AT were obviously higher than those with other systems in the initial flowering stage, except for TNA under N 21. The parameters regarding the nodulation and N fixation ability were significantly positively correlated on the whole. However, SNW and TNA were not significantly correlated, neither were SNW and TDW. According to the mentioned results, the closer root interaction, the better the nodulation form and N fixation ability of alfalfa will be, and the higher the biomass and N accumulation of all plants in pots will be. Interspecific facilitation in alfalfa/triticale intercropping system resulted in a greater yield and N accumulation; it also ultimately enhanced nodulation and N fixation ability, which can be applied in sustainable systems to avoid N loss to the environment and enhance N use efficiency.

“…The accumulation of autotoxic compounds is an important factor contributing to soil sickness, as autotoxic compounds can promote the propagation of soil-borne pathogens (Bever et al, 2012;Zhou et al, 2017). It has been shown that interspecific plant interactions are able to change plant secondary metabolism (Broz et al, 2010;Li et al, 2016;Liu et al, 2017). Lv et al (2018) found that the intercropping of wheat inhibited watermelon from exudating phenolic autotoxins.…”

Enhancing the plant rhizosphere microbial community function by increasing plant diversity in the field is a promising strategy for enhancing agricultural sustainability. This study evaluated the effectiveness of the intercropping of wheat in controlling cucumber Fusarium wilt disease. Bacterial community diversity and abundance in cucumber rhizosphere were estimated by high-throughput amplicon sequencing and quantitative polymerase chain reaction (PCR). Results showed that the intercropping of wheat inhibited the severity of cucumber seedling Fusarium wilt disease, increased the alpha diversity and altered the composition of the bacterial community in cucumber rhizosphere. Compared with monocropped cucumber, intercropped cucumber had higher relative abundances of Anaerolineae, Deltaproteobacteria, Phycisphaerae and Planctomycetacia, and lower Alphaproteobacteria and Cyanobacteria. Moreover, the intercropping of wheat promoted bacterial genera with plant-beneficial potential (e.g. Pseudomonas, Haliangium and Archangium spp.) in cucumber rhizosphere. Quantitative PCR confirmed that Pseudomonas spp. abundance was higher in intercropped cucumber rhizosphere than in monocropped cucumber rhizosphere. Overall, the intercropping of wheat decreased the severity of Fusarium wilt of cucumber and promoted potential plant-beneficial microbes in cucumber rhizosphere.

“…Flavonoids serve as primary signals and are released by the host plants that act as chemoattractants [ 42 ], activating the expression of rhizobia node genes. The function of flavonoids in the nodulation process has been studied by several researchers [ 42 - 44 ]. Van Noorden et al [ 45 ] observed the interaction of Sinorhizobium meliloti with 131 identified proteins in Medicago truncatula .…”

: Plants do not grow in isolation, rather they are also hosts to a variety of microbes in their natural environments. While, few thrive in the plants for their sole benefit, others may have a direct bearing on plants in a symbiotic manner. Unravelling plant-microbe interactions is a crucial component to recognize the beneficial and detrimental impact of microbes on plants. Also, by affecting the environment around plants, microbes may indirectly influence the plants. The progress in sequencing technologies in the genomics era and several omics tool has grown in biological science. Studying the complex nature of plant-microbe interactions can offer several strategies to increase productivity of plants in an environmentally friendly manner by providing better insights. This review brings forward the recent works performed in building omics strategies that decipher the interactions between plantmicrobiome. At the same time, this study further explores other associated mutually beneficial aspects of plant-microbe interactions such as plant growth promotion, nitrogen fixation, stress suppressions in crops and bioremediation. This work also provides a better intelligence about metabolic interactions between the microbe and the plant through omics approaches. The review explores advances in the study of Arabidopsis as an important avenue to serve as a baseline tool to create models that help in scrutinizing various factors that contribute to the elaborate relationship between the plant and microbes. Causal relationships between plants and microbes can be established through systematic gnotobiotic experimental studies to test hypotheses on biologically derived interactions. This review will bring forth recent advances in the study of plant-microbe interactions keeping in view the advantages of these interactions in improving nutrient uptake and plant health.
