<title>Abstract</title> Apple replant disease (ARD) describes a phenomenon of reduction crop productivity in the early years orchard establishment sites previously planted to apple. Currently manipulation soil microbiome by (bio)fumigation is major approach alleviate ARD. Adjustment rootstock harsh biotic factors might be an alternative combat In this study we evaluated differences structure and composition between nursery mature trees, grown Nova Scotian apple orchards. We showed that tree...
The application of bacterial inoculums for improving plant growth and production is an important component sustainable agriculture. However, the efficiency perennial crop depends on ability introduced endophytes to exert impact host-plant over extended period time. This might be evaluated by response plant-associated microbiome inoculation. In this study, we monitored effect a single strain inoculation diversity, structure, cooperation in 1-year period. An endophyte (RF67) isolated from...
The tree fruit industry in Nova Scotia, Canada, is dominated by the apple (Malus domestica) sector. However, sector faced with numerous challenges, including replant disease (ARD), which a well-known problem areas intensive cultivation. A study was performed using 16S rRNA/18S rRNA and rRNA/ITS2 amplicon sequencing to assess soil- root-associated microbiomes, respectively, from mature orchards soil microbiomes alone uncultivated soil. results indicated significant (p < 0.05) differences...
The benefit sof municipal solid waste (MSW) compost on soil health and plant productivity are well known, but not its long-term effect microbial metabolic pathways. A 5-year study with annual (AN), biennial (BI) no (C, control) MSW application were carried out to determine the properties, microbiome function, plantgrowth TCA cycle metabolites profile of green beans (Phaseolus vulgaris), lettuce (Latuca sativa) beets (Beta vulgaris). increased nutrients organic matter leading a significant (p...
Using tandem mass spectrometry (MS/MS), we analyzed the proteome of Sinorhizobium medicae WSM419 growing as free-living cells and in symbiosis with Medicago truncatula. In all, 3,215 proteins were identified, over half open reading frames predicted from genomic sequence. The abundance 1,361 displayed strong lifestyle bias. total, 1,131 had similar levels bacteroids cells, low 723 prevented statistically significant assignments. Nitrogenase subunits comprised approximately 12% quantified...
Aloe vera is being identified as a potential medicinal plant for its application in industries well traditional usage.The gel obtained from the leaves of A. has numerous properties.In this study, using to extend shelf life Ampalavi mango fruits was studied.Even sized, uniform coloured, matured cultivar were surface cleaned and coated with 33%, 66% 100% gel, respectively.Results revealed that ripening delayed due coating.The total soluble solid (TSS), pH weight loss high uncoated fruits.The...
Compost residue enriches soil health with the potential to enhance plant metabolism and hormonal balance, but has not yet been studied. A study was performed determine how prevailing compost induces tomato (Solanum lycopersicum 'Scotia') morpho-physiology, phytohormones, secondary metabolites. Plants were grown in soils a previous history of annual (AN) biennial (BI) amendments. The controls without (C) amendment municipal solid waste (MSWC) alone. MSWC- AN-plants had similar significantly...
Sinorhizobium meliloti 1021 bacteria secretes a considerable amount of flavins (FLs) and can form nitrogen-fixing symbiosis with legumes. This strain is also associated non-legume plants. However, its role in plant growth promotion (PGP) non-legumes not well understood. The present study evaluated the development lettuce (Lactuca sativa) kale (Brassica oleracea var. acephala) plants inoculated S. (FL+) mutant 1021ΔribBA, limited ability to secrete FLs (FL−). results from this indicated that...
