To explore and utilize the abundant soil microorganisms their beneficial functions, high-throughput sequencing technology was used to analyze microbial compositions in rhizosphere of red green amaranth varieties. The results showed that significant differences composition could be found plants with different color phenotypes. Firstly, bacterial were significantly between amaranths. Among them,

ABSTRACT The rhizosphere, as the primary site of plant–soil –microbe interactions, plays an important role in plant productivity. influence species on rhizosphere soil properties and how this shapes productivity grassland ecosystems remains poorly understood. Therefore, study analyzed changes bacterial community structure metabolites perennial cultivated grassland. aim was to elucidate pathways underlying mechanisms by which physicochemical properties, structure, Taking monocropping grasslands established with three common grass from Qinghai –Tibet Plateau research objects, a comprehensive conducted using replicated field trials. Rhizosphere samples were collected Elymus breviaristatus , Festuca sinensis Poa pratensis . results indicated significant differences productivity, diversity, among grasslands. Among them, ANPP (589.17 g·m −2 ), root biomass (3601.67 moisture (18.15%) Verrucomicrobiota (3.60%) are higher than those while relative abundance Firmicutes (0.82%) is lower that topological characteristics networks varied different species. abundances consisting phenylalanine, proline, raffinose, maltotriose, uridine, 2‐methylbenzaldehyde differed treatments. Pathway analysis highlighted upregulation ABC transporters pyrimidine metabolism compared Moreover, secreted more prevents recruitment pathogenic bacteria (such ) promotes thus improving These findings show around Lake result interaction nutrients, metabolites, microorganisms. From ecological point view, conducive improvement forage yield restoration degraded

Root hairs are specialized tubular extensions that play a pivotal role in nutrient absorption and plant-soil interactions. Typically, they originate from epidermal cells, which differentiate into either hair cells or non-hair cells. In blueberry (Vaccinium spp.), the roots devoid of root hairs. To examine mechanisms responsible for hairless phenotype, this study conducted anatomical molecular biological investigations on blueberry. The exhibit uniformity size cross-sectional dimensions, with each cell interfacing two neighboring cortical This distinctive pattern, differs three known patterns observed other plant species, is classified as type IV. CAPRICE (CPC) gene, encodes an R3-type MYB transcription factor, positive regulator differentiation Arabidopsis. Functional analyses utilizing Arabidopsis demonstrated VcCPC homolog retained its capacity to promote formation wild-type cpc mutant plants. GUS histochemical analysis revealed promoter active multiple organs transgenic Arabidopsis, including leaves, flowers, fruit, maturation zone, but not regions associated fate determination, such elongation zone meristematic zone. Complementation chimeric VcCPCpro::VcCPC construct did restore hair-deficient phenotype. Substitution sequence (nt - 709 1) AtCPC 683 effectively restored phenotype mutant. Blueberry IV patterning, previously identified epidermis-cortex patterns. Although maintains conserved promoting apical silencing VcCPC, conjunction novel epidermal-cortical may contribute Substituting native development mutant, indicating regulatory elements present promoter, absent might mediate phenotypic divergence.

Current agricultural practices face numerous challenges, including declining soil fertility and heavy reliance on chemical inputs. Rhizosphere microbial metabolites have emerged as promising agents for enhancing crop health yield in a sustainable manner. These metabolites, phytohormones, antibiotics, volatile organic compounds, play critical roles promoting plant growth, boosting resistance to pathogens, improving resilience environmental stresses. This review comprehensively outlines the mechanisms through which rhizosphere influence health, traits, functional components, yield. It also discusses potential applications of secondary biofertilizers highlights challenges associated with their production practical use. Measures overcome these are proposed, alongside an exploration future development fertilizer industry. The findings presented here provide scientific basis utilizing enhance sustainability, offering new strategies management. Integrating could lead increased productivity, improved quality, reduced dependence synthetic inputs, thereby supporting more environmentally friendly resilient system.
