Plant species‐rich systems tend to be more productive than depauperate ones. In agroecosystems, increasing crop plant diversity by including legumes often increases soil nitrogen (N) and improves soil fertility; however, such generality in outcomes of non‐leguminous crop mixture is unknown. Here, through a meta‐analysis of 174 individual cases, we...

Background Volatile organic compounds (VOCs) released by plants can act as signaling molecules mediating ecological interactions. Therefore, the study of VOCs mediated intra- and interspecific interactions with downstream plant physiological responses is critical to advance our understanding of mechanisms underlying information exchange in plants....

Climate change threatens global food and nutritional security through negative effects on crop growth and agricultural productivity. Many countries have adopted ambitious climate change mitigation and adaptation targets that will exacerbate the problem, as they require significant changes in current agri-food systems. In this review, we provide a r...

Plants release chemical signals to interact with their environment when exposed to stress. Khait and colleagues unveiled that plants 'verbalize' stress by emitting airborne sounds. These can train machine learning models to identify plant stressors. This unlocks a new path in plant-environment interactions research with multiple possibilities for f...

Terrestrial plants can affect the growth and health of adjacent plants via interspecific interaction. Here, we studied the mechanism by which plant root exudates affect the recruitment of the rhizosphere microbiome in adjacent plants - with implications for plant protection - using a tomato (Solanum lycopersicum)-potatoonion (Allium cepa var. agrog...

Plants have evolved sophisticated mechanisms to detect various forms of danger. Damage-associated molecular patterns (DAMPs) are endogenous danger molecules that are released from damaged cells and activate the innate immunity. Recent evidence suggests that plant extracellular self-DNA (esDNA) can serve as a DAMP molecule. However, the mechanisms b...

Interaction Despite numerous recent insights into neighbor detection and belowground plant communication mediated by root exudates, less is known about the specificity and nature of substances within root exudates and the mechanism by which they may act belowground in root-root interactions. Methods Here, we used a coculture experiment to study th...

Modification of biochar, such as impregnation with minerals, can improve biochar’s efficacy to mitigate heavy metal toxicity in plants. Biochar amendments can alter plant rhizosphere microbiome, which has profound effects on plant growth and fitness. Here, we tested whether rhizosphere microbiome is involved in the ability of silicon (Si)-modified...

Biochar amendment is acknowledged to favor plant resistance against soil‐borne diseases. Although plant‐beneficial bacteria enrichment in the rhizosphere is often proposed to be associated with this protection, the mechanism behind this stimulating effect remains unelucidated. Here, we tested whether biochar promotes plants to recruit beneficial ba...

Plants constantly communicate with coexisting neighbors and adjust their physiological and morphological characteristics, including changes in root system architecture (RSA). Increased or decreased biomass accumulation, horizontal and vertical asymmetric distribution are the main behavioral performances. Some evidence has shown that these performan...

Cover crops can improve soil biological health and alter the composition of soil microbial communities in agricultural systems. However, the effects of diversified cover crops on soil microbial communities in continuous cropping systems are unclear. Here, using different soil biochemical analysis, quantitative PCR and 16S rRNA amplicon sequencing,...

In this study, we investigated the effects of wheat root exudates on soil bacterial communities in the watermelon rhizosphere using quantitative PCR and Illumina MiSeq sequencing. The qPCR results showed that wheat root exudates significantly increased the abundance of total bacteria, Pseudomonas, Bacillus and Streptomyces spp. Illumina MiSeq seque...

Plant interspecific interactions can be influenced by common mycorrhizal networks (CMNs), which mediate nutrient trade (rarely focused on K and such fungal benefits), but the involved mechanisms remain unclear. To test whether and how CMNs mediate nutrient trade to benefit individuals during interspecific interactions, the growth advantage and K di...

The application of biochar stimulates the activities of microorganisms that affect soil quality and plant growth. However, studies on the impacts of biochar mainly focus on a monoculture, its effects on interspecific interactions are rarely reported. Here, we investigated the impacts of biochar on tomato/potato–onion intercropped (TO) in a pot expe...

Agricultural intensification is known to alter the assembly of soil microbial communities, which regulate several critical ecosystem processes. However, the underlying ecological processes driving changes in microbial community assembly, particularly at the regional scale, remain poorly understood. Using 16S rDNA sequencing, we characterized soil b...

Background and aimsCrop diversification usually increase nutrient use efficiency and productivity of crops, but we still lack deeper understandings of the underlying mechanisms. Here we aimed to study the role of root exudates and soil microbial communities in mobilization of soil P during an intercropping system.Methods Different barrier treatment...

The traditional way of monocropping and current strategies of use of inorganic chemical-based pesticides and fertilizers are the main barriers in development of sustainable agriculture. Similarly, sickness is a growing issue because of degradation of agricultural land due to continuous sole cropping. On the other hand, intercropping is an old but e...

Palmitic acid (PA) in root exudates or decaying residues can reduce the incidence of soil-borne diseases and promote the growth of some crop plants. However, the effects of PA on soil-borne pathogens and microbial communities are poorly understood. Here, we investigate the effects of PA on overall watermelon microbial communities and the population...

e studied the effects of exogenously applied palmitic acid (PA) on reactive oxygen species (ROS) production, defense-related enzyme activity and malondialdehyde (MDA) content of roots and analyzed the response of defense-related genes in Fusarium oxysporum f.sp.niveum (FON) inoculated watermelon (Citrullus lanatus (Thunb.) Matsum. et Nakai). Our re...

Facilitative interactions occur between the plants in intercropping systems, however, the underlying allelopathy mechanisms are poorly understood. We determined the effects of potato-onion (Allium cepa var. agrogatum Don.) intercrop on root morphology of tomato (Lycopersicon esculenum L.) through volatile organic compounds (VOCs). There were four t...

We studied the effects of 7-crop rotations and continuous - monocropping systems on soil microorganism and its feedback. The results showed that absolute abundance of soil bacteria (Pseudomonas and Bacillus) in tomato - celery - cucumber - cabbage and cucumber - tomato - cucumber - cabbage rotation were significantly higher than control (CK). Absol...

Straw amendment can improve soil properties and is an effective strategy to control soil-borne diseases. However, gramineous straw application to vegetable fields has rarely been studied. In this study, rice straw was added to the field of Chinese cabbage for one or two years (repeated), and Chinese cabbage plant growth, disease occurrence and chan...

The low availability of soil nutrients such as phosphorus (P) has a huge impact on crop production. At the same time, crop plants have also developed complex adaptive mechanisms to low availability of nutrients for their survival. These physiological, molecular, and biochemical responses to P stress involve sensing, signaling pathways, systemic com...

Background and aims The relationship between wheat root exudates and watermelon rhizosphere microbial communities in wheat/watermelon cropping system is well documented now, however, less is known about the activity of allelochemicals in wheat root exudates against watermelon Fusarium oxysporum f. sp. niveum (FON), and how it may influence belowgro...

We grew cucumber in pots in greenhouse for 9-successive cropping cycles and analyzed the rhizosphere Pseudomonas spp. community structure and abundance by PCR-denaturing gradient gel electrophoresis and quantitative PCR. Results showed that continuous monocropping changed the cucumber rhizosphere Pseudomonas spp. community. The number of DGGE bands...

Continuous monocropping can cause the buildup of autotoxins (e.g., phenolic compounds) in the soil, which can alter soil microbial community and inhibit plant growth. However, how different phenolic compounds affect certain soil microbiota is unclear. Here, we studied the response of cucumber rhizosphere Trichoderma spp. community to exogenously ap...

We investigated in greenhouse experiment, the effects of intercropping of wheat (Triticum aestivum L.) with cucumber (Cucumis sativus L.) on the leaf senescence of later crop. The leaves of the cucumber plants under wheat intercropping (CW) showed higher chlorophyll content and lower intercellular CO2 concentration than in cucumber monocropping (C...

Plant-microbes interactions in soil are mainly driven by plant root exudates. However, how different compounds present in root exudates can affect the specific soil microbial communities has not been well studied yet. We studied the glucose, succinic, p-hydroxybenzoic, p-coumaric and glutamic acids on soil Pseudomonas spp. communality in a microcos...

Sub-optimal temperatures can adversely affect tomato (Solanum lycopersicum) growth, and K+ plays an important role in the cold tolerance of plants. However, gene expression and K+ uptake in tomato in response to sub-optimal temperatures are still not very clear. To address these questions, one cold-tolerant tomato cultivar, Dongnong 722 (T722), and...

It is well established now that cropping system has great influence on soil microbial communities, but still advance techniques are required to study more of changes in soil microbiota during cropping systems. Here we used high-throughput sequencing to explore the effects of crop rotation with Indian mustard on composition of cucumber rhizosphere f...

In the last few decades, incredible advances have been made in understanding the way of communication among members of kingdom plantae. Some plants fight for their existence and try to suppress the growth of other plants, while some share resources to benefit each other for their survival. During all these processes, plants use several biotic and a...
