Abstract Fertilizer input is one of the effective forest management practices, which improves soil nutrients and microbial community compositions promotes productivity. However, few studies have explored response rhizosphere communities to various fertilization regimes across seasonal dynamics. Here, we collected samples from Phoebe bournei plantations investigate assemblages interactions microbiome short-term application four typical fertilizer practices (including chemical (CF), organic (OF), compound (CMF), no control (CK)). The amendments altered composition bacterial fungal communities, respectively. regime significantly affected diversity rather than diversity, fungi responded more sensitively bacteria season. Fertilization-induced networks were complex networks. Stochastic processes governed both drift dispersal limitation dominated Collectively, these findings demonstrate contrasting responses practices. strengthens changes succession key taxa in habitat.

QTL analysis and fine mapping of a major QTL and identification of candidate genes controlling curd setting height in cauliflower

Vegetable Research, Год журнала: 2024, Номер 4(1), С. 0 - 0

Опубликована: Янв. 1, 2024

Curd setting height, a critical component of plant plays an important role in ideotype construction and yield improvement cauliflower. However, the underlying mechanisms governing this trait Brassica crops remain unclear. In study, we developed two F₂ populations by crossing cauliflower DH line, ZAASC4101, having short main stem, with Brassica oleracea inbred lines possessing long stem. Subsequently, high-density linkage maps were constructed for each population using 10K MNP (multiple nucleotide polymorphism) array species. These covered genetic distances 8,373.66 cM 8,250.01 cM, respectively. Notably, major QTL related to curd height (BocDWARF1) was consistently identified on chromosome C01 highest LOD value both populations. Through analysis recombinants from F_2:3 F_3:4 at BocDWARF1 locus, successfully fine-mapped locus narrow interval delimited SNP markers 1_40298271 1_40400283. This corresponds approximately 102-kb region harboring 12 predicted genes. Combined parental resequencing data HDEM reference genome annotation information, proposed BolC1t04399H as most promising candidate gene. gene exhibits homology well-known height-controlling DWARF1 shows total four nonsynonymous SNPs exon between parents. study lays foundation map-based cloning provides valuable insights breeding improved varieties ideal height.

Arable soil and crop productivity are severely affected by salinization. Therefore, amendments an important measure for improving saline-alkali agricultural development. Desulfurized gypsum is a common amendment that has been used repeatedly alongside organic materials to improve the biological, physical, chemical properties of saline soil. This study takes typical farmland in Yulin as research object, five treatments were established: blank treatment (CK), single application 2.5 t ha −1 desulfurized (T), 1.5 green manure (TL), straw (TS), fertilizer (TV). The results show TV achieved significant improvement nutrients, carbon, enzyme activity, maize yield. In 2022 (2023), compared matter, TN, TP, TK, AP, AK increased significantly with CK when was applied. Soil phosphatase activity (SPA), urease (SUA) sucrase (SSA) higher other over two-year period. Furthermore, carbon (SOC), easily oxidizable (EOC), dissolved (DOC) microbial biomass (MBC) also 2023 treatments. Correlation analysis revealed positive relationship between yield ( P < 0.05). Thus, determined be optimal improvement. conclusion supported analyses performed using membership function analysis, gray correlation entropy TOPSIS model evaluation. this method increases quality, improves fertility, achieves high yields, provides scientific basis enhancing utilizing Loess Plateau.

Soil beneficial microorganism deficiency in the degraded grasslands have emerged as major factors negatively impacting soil quality and vegetation productivity. EM (effective microorganisms) has been regarded a good ameliorant improving microbial communities restoring of agricultural systems. However, knowledge was inadequate regarding effects adding on alpine grassland. Four levels addition (0, 150, 200, 250 mL m –2 ) were conducted to investigate properties microorganisms The increased aboveground biomass, organic carbon, total nitrogen, available phosphorus, but decreased electric conductivity. Meanwhile, relative biomasses gram-negative bacteria decreased, while ectomycorrhizal fungi arbuscular mycorrhizal after addition. relationship between environmental changed. restore effect with increase time. These results indicated that could be practice health grassland ecosystem.

Agronomy, Год журнала: 2024, Номер 14(5), С. 1016 - 1016

Опубликована: Май 10, 2024

Microbial inoculants derived from plant growth-promoting rhizobacteria (PGPR) offer eco-friendly alternatives to traditional chemical fertilizers, maintaining microbiota balance in agricultural systems. However, limited research has explored the combined effects of microbial and fertilizers on crop growth soil properties. In this study, we investigated seven fertilizer combinations, ranging no various proportions with inoculants, timothy (Phleum pratense L.) growth, chlorophyll content, properties, enzyme activities, communities. A randomized block design was employed analyze these effects. The results indicate that combination 85% significantly increased yield content. addition, a reduction 55% conjunction resulted comparable 100% inoculants. treatments notably elevated catalase, urease, acid phosphatase, invertase along fast-acting nutrient sequencing show abundance beneficial bacteria increased, while fungi decreased rhizosphere after application This study underscored potential reductions enhance microbiology, suppressing pathogenic fungi, thereby promoting yield. These findings provide theoretical basis for use sustainable practices, providing valuable insights optimizing formulations mitigate sustainability challenges posed by conventional fertilizers.
