Different rhizosphere soil microbes are recruited by tomatoes with different fruit color phenotypes

Abstract

Background To explore and utilize abundant soil microbes and their beneficial functions, the bacterial and fungal compositions in rhizospheres between red- and yellow-fruited tomato varieties were analyzed using high-throughput sequencing technique. Result Our results indicated that different soil microbes in rhizospheres of tomatoes were exactly recruited by different color fruit tomatoes. For the reasons as not only soil bacterial community, but also soil fungal compositions were all different between red and yellow fruit tomatoes. For example, Nocardioides, norank_f_norank_o_Vicinamibacterales, norank_f_norank_o_norank_c_KD4-96, norank_f_Birii41, norank_f_norank_o_S085 and Bradyrhizobium were the specific dominant soil bacterial genera, and Lecythophora, Derxomyces and unclassified_f_Pyronemataceae were the dominant soil fungal genera in the rhizospheres of red tomato varieties. By contrast, unclassified_f__Micromonsporaceae, Acidipila, Roseisolibacter, Gaiella and norank_f_Xanthobacteraceae were the unique dominant soil bacterial genera in the rhizospheres of yellow tomato varieties. And unclassified_o__Onygenales, Trichocladium, unclassified_c__Sordariomycetes, Pseudogymnoascus, Acremonium, Oidiodendron, Phialemonium, Penicillium, Phialosimplex were the unique dominant soil fungal genera in rhizospheres of yellow tomato varieties. Moreover, a higher abundance of specific soil bacterial and fungal genera in the rhizosphere was found in rhizospheres of the yellow than those of the red tomato varieties. Conclusion Soil bacterial and fungal compositions in rhizospheres between red- and yellow-fruited tomato varieties were found significantly different which growing in the same environment under the identical managements. It suggested that different soil microbes in rhizospheres exactly were recruited by different phenotypes tomato varieties related to fruit color formation.

Changes in Soil Phosphorus Availability and Microbial Community Structures in Rhizospheres of Oilseed Rapes Induced by Intercropping with White Lupins

“…Moreover, soil microbial biomass is also an important indicator for evaluating soil fertility [ 46 ], and the turnover of soil MBP could release inorganic phosphorus [ 52 ]. Additionally, soil phosphatases can be produced by plant roots and microbes in soil [ 53 ].…”

“…Sequencing was performed using Illumina’s MiSeq PE250 and MiSeq PE300 platform (Shanghai Majorbio Biopharm Technology Co., Ltd., Shanghai, China). The processing and analysis of sequencing data were described previously in detail [ 45 , 46 ]…”

Geographical variation of Geochemistry and Bacteriome of Maize Rhizosphere in Agricultural Farmlands

“…The ability of rhizosphere Streptomyces to enhance crop growth and stem ambient stress to promote crop health has variously reported in many crops(Hu et al, 2020;Kum and Ince, 2021;Pang et al, 2022). the maize apparently related with marginal differences among the habitats(Ni et al, 2023) and differ according to phylogenetic distance of crops(Chen et al, 2022;Lopes et al, 2023), in this case, the maize. The highest bacterial richness estimated via diversity indexes associated with Ma2R (6017) further consolidate the assertion that the rhizosphere in the southern part are relatively more nutritive for maize cultivation.…”

How Rhizosphere Microbial Assemblage Is Influenced by Dragon Fruits with White and Red Flesh

“…Additionally, a mulberry variety resistant to bacterial wilt was reported to be enriched with fungal communities that can prevent the spread of soil-borne diseases, enhance plant drought resistance, and provide tolerance against biological or abiotic stresses [23]. Chen et al [24] found that different rhizospheric soil microbes are recruited by tomatoes with different fruit color phenotypes. Xiao et al [25] also found differences in rhizospheric microbes recruited by different watermelon phenotypes relating to rind color formation.…”
