Legumes have important nutritional and economic values, but their production faces continuous cropping obstacles that seriously affect yield formation. In order to reduce the negative impact of legumes, it is necessary understand response mechanisms legumes cropping, causes measures alleviate obstacles. This review aimed identify current knowledge gap in field provide direction focus for future research. The start with soil degradation, leading oxidative stress plants. triggers expression plant-hormone- signal-molecule-related genes, activating defense system causing Although there has been progress researching these challenges legume crops, many questions remain. We believe exploration molecular crops responding rhizosphere signal exchange environment repair after long-term soybean, excavation candidate genes functional loci related are breakthroughs proposing effective obstacle management strategies future.

ABSTRACT Multifunctional plant growth-promoting rhizobacteria (PGPR) have garnered significant attention in agricultural applications; however, a few applied them crop rotation or intercropping fields. To identify PGPR with strong colonization ability and broad spectrum benefit, we screened strains from the local tobacco rhizosphere evaluated their effects across various crops farming systems. In this study, strain L8, identified as Bacillus thuringiensis , was selected multifunctional capable of producing indole-3-acetic acid (IAA), solubilizing potassium, mobilizing both organic inorganic phosphorus. Compared control group, soil treated L8 pot experiments showed significantly higher levels IAA, available Furthermore, plants inoculated exhibited improved growth parameters compared uninoculated control. The results indicated that control, increased fresh weight (by 83.18%), height 29.32%), relative chlorophyll content 14.33%), well phosphorus 23.78%) potassium 30.81%). Interestingly, not only enhanced but also root morphology, increasing length (1.55-fold), surface area (1.78-fold), volume (2.05-fold) These findings provide valuable insights into utilizing bacteria for production. Moreover, inoculation enriched matter nutrient wheat ( Triticum aestivum )-maize Zea mays ) peanut Arachis hypogaea within intricate tillage systems wheat-corn peanut-corn intercropping, can play crucial role promotion, yield increase, availability. IMPORTANCE aim to study application diverse complex planting systems, showing adaptability effectiveness contexts. suggests improves utilization soil, enhances health, plays through secretion substances like auxin (IAA). parallel, observed applying production efficiency wheat, corn, peanuts indicating method holds potential enhancing quality crops.

Continuous cropping obstacles pose significant constraints and urgent challenges in the production of Tussilago farfara L. This experiment investigated effects consecutive on T. over periods 1, 2, 3 years. It assessed yield quality flower buds, addition to physicochemical properties rhizosphere soil. The microbial community was analyzed through 16S rDNA ITS sequencing using Illumina Novaseq high-throughput technology, while also examining correlations among these factors. results reveal that as duration continuous increases, along with contents extract, tussilagone, total flavonoids, steadily decreased; soil pH, organic matter, available phosphorus, potassium, alkaline nitrogen, activities sucrose, catalase, phosphatase markedly decreased. As quantity diversity bacteria initially increase then decrease, number fungal species increases by 22.5%. Meanwhile, contributes a gradual reduction relative abundance beneficial genera such Ralstonia, Nitrospira, Trichoderma soil, harmful Mortierella, Fusarium, Tricharina accumulate significantly. Correlation analysis shows changes communities notably influence growth quality. study elucidates impacts properties, rhizosphere, providing scientific basis for further research barriers selection farfara.

As is well known, continuous cropping can lead to a decrease in crop yield and quality. Despite this, remains prevalent practical agricultural production, particularly the case of tobacco cultivation, owing its high economic value. The samples for this study were collected from flue-cured planting base located Huili County, Liangshan Yi Autonomous Prefecture, Sichuan Province, China. After years planting, has significantly decreased. In order explain microecological causes phenomenon, we non-continuous cropping, 5 years, 10 rhizosphere soil, analyzed effects long-term on nutrients, enzyme activities, microbial community structure, function soil. results showed that with majority nutrients (except phosphorus manganese) soil decreased significantly, structure changed significantly. Correlation network analysis changes closely related urease, active organic carbon, available iron content. functional based microorganisms genes microbiota may change content through iron_respiration, sulfur_respiration, Carbon fixation prokaryotes pathways. correlation mutually confirmed each other, both emphasizing important role carbon shaping community. Based study, propose improve by increasing levels readily oxidizable iron, urease activity future, so as alleviate negative impact yield. provide theoretical support modifying environment nutrient regulation, thereby enhancing plant growth context cropping.

Introduction Continuous cropping challenges have gradually emerged as pivotal factors limiting the sustainable development of agricultural production. Allelopathicals are considered to be primary obstacles. However, there is limited information on allelopathic accumulation across various continuous years and its correlation with associated challenges. Methods Tobacco was subjected varying planting durations: 1 year (CR), 5 (CC5), 10 (CC10), 15 (CC15). Results Our findings unveiled discernible disparities in tobacco growth patterns diverse periods. Notably, most pronounced were observed CC5 category, characterized by yield reduction, black shank outbreaks, a decline beneficial flora. Conversely, CC15 exhibited substantial reduction persisted no significant differences when compared CR. Within rhizosphere, we identified 14 distinct compounds, these compounds displaying noteworthy variations among four treatments. Redundancy analysis (RDA) revealed that eight autotoxic effects growth, MA, heptadecanoic acid, VA ranking potent inhibitors. Interaction network highlighted roles EA promoting pathogen proliferation impeding enrichment 13 bacterial genera. Furthermore, structural equation model elucidated MA primarily exert direct toxic tobacco, whereas fosters proliferation, inhibits bacteria, synergistically exacerbates alongside EA. Discussion These suggested The CC5, persisted. may play role this phenomenon interacting pathogens, genera,

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

Aviation mutagenesis is a breeding method for the rapid selection of superior plant varieties. In this study, rhizosphere soil chemical indexes, enzyme activities, and metabolites were measured in Dahongpao tea trees with aviation (TM) without (CK). The main distinguishing TM CK their relationships indexes activities analyzed obtained. results showed that there was no significant change soils’ pH compared to (p = 0.91), while all other significantly higher than < 0.05). addition, enzymes related nutrient cycling such as urease, protease, sucrase, acid phosphatase cellulase, antioxidants superoxide dismutase, catalase, peroxidase, polyphenol oxidase increased 0.05) soils CK. Soil metabolite analysis from carbohydrates, nitrogen compounds, amines. Of these, carbohydrates compounds positively correlated enzymes, whereas amine negatively organic matter, total nitrogen, potassium, available phosphorus; negative correlation oxidase, urease. It can be seen conducive improving ability tree aggregation transformation nutrients, increasing amount nutrients content which more promoting uptake by tree, thus growth tree.
