“…Group J0_5cm showed a higher OTU abundance of endophytic bacterial than group J5_10cm, most likely because the group J0_5cm was closer to the root, which indicated that it possessed the advantage of having more contact with the microorganisms in the environment around the root. However, endophytic bacterial can enter the host plant through tissue lesions and plant stomata ( Rincón and Neelam, 2021 ). The result showed that the endophytic bacterial community showed its highest diversity and richness in group J10_15cm, which may be because the endophytic bacterial in group J10_15cm was not only transferred vertically from the roots but also came in partly through the stomata of the stems and leaves.…”

Analysis of Endophytic Bacterial Diversity From Different Dendrobium Stems and Discovery of an Endophyte Produced Dendrobine-Type Sesquiterpenoid Alkaloids

As the unique component of Dendrobium, dendrobine-type sesquiterpenoid alkaloids (DSAs) possess a variety of medicinal properties. It has been well documented that plant endophytes can in vitro synthesize secondary metabolites identical or similar to metabolites produced by their host plants. This study aimed to investigate the composition and distribution of endophytic bacteria of Dendrobium stems by Illumina MiSeq platform sequencing and cultivation-dependent methods and then to assess the potential for endophytic bacteria to produce DSAs. Results indicated that it was necessary to combine both cultivation-dependent and cultivation-independent methods to analyze the community structure of endophytic bacterial in plants comprehensively. The length of the Dendrobium stems influenced the endophytic bacterial community. The diversity and richness of endophytic bacteria in group J10_15cm of stems were the highest, which showed a significant difference from the other stem groups. However, there was no certain connection between the diversity and richness of endophytic bacteria and the content of dendrobine. It was most likely due to the influence of several specific endophytic bacteria genera, such as Sphingomonas and Rhodococcus. Athelia rolfsii, Myrothecium roridum, as pathogenic fungi, and Pectobacterium carotovorum subsp. actinidiae, as pathogenic bacteria of Dendrobium, were used to determine the antimicrobial activities. In these assays, six strains belonging to five genera showed antimicrobial activity against at least two phytopathogens. The strain BL-YJ10_15-29 (Paracoccus pueri THG-N2.35, 98.98%) showed the best antimicrobial activity against the three phytopathogens. In addition, 2 DSAs (6-hydroxydendrobine and nobilonine) were identified in the fermentation supernatant of the strain CM-YJ10_15-44 (Pseudomonas protegens CHA0, 99.24%), whereas the whole-genome analysis results further demonstrated that the precursors of the two DSAs [geranyl-PP and (E, E)-famesyl-PP] were synthesized mainly through the methyl-D-erythritol 4-phosphate pathway in this strain. This study provides new insight into the studies on the biosynthesis of DSAs and provides potential biocontrol bacteria.

“…It is important to note that raw fruit and vegetables are also one of the main sources of pathogen acquisition including Listeria monocytogenes , Salmonella , Escherichia coli , all of which form health hazards 106 . A study by Rincón and Neelam 107 found that tomato, lettuce, spinach, maize, pepper, mustard, soybean, artichoke, and pumpkin mostly come with good bacteria. Broccoli, cauliflower, cabbage, carrot, celery, chili, cucumber, parsley, pepper, and radish often harbor pathogenic bacteria.…”

This paper investigates how reticulate evolution contributes to a better understanding of human sociocultural evolution in general, and community formation in particular. Reticulate evolution is evolution as it occurs by means of symbiosis, symbiogenesis, lateral gene transfer, infective heredity, and hybridization. From these mechanisms and processes, we mainly zoom in on symbiosis and we investigate how it underlies the rise of (1) human, plant, animal, and machine interactions typical of agriculture, animal husbandry, farming, and industrialization;(2) diet-microbiome relationships; and (3) host-virome and other pathogen interactions that underlie human health and disease. We demonstrate that reticulate evolution necessitates an understanding of behavioral and cultural evolution at a community level, where reticulate causal processes underlie the rise of synergistic organizational traits.

Aims: This study aimed to evaluate the genetic and functional diversity of bacteria associated with the surfaces of Prunus persica (L.) Batsch. Methodology: A total of 15 peach samples from various areas of Lahore city were collected and processed according to standard microbiological protocols. The final taxonomic status of bacterial strains was confirmed by 16S rRNA gene sequencing. Bacterial strains were screened for plant growth-promoting attributes that included auxin production, phosphate, and zinc solubilization, and hydrogen cyanide (HCN) production. Antimicrobial activity of strains was also evaluated. In pot trials, strains were evaluated for their role to enhance plant growth. Results: Analysis showed that bacterial isolates belonged to Bacillus, Staphylococcus, Klebsiella, Enterobacter, and Providencia genera. A strain KS 22 of Staphylococcus sciuri showed the highest production of auxin. In terms of antibiotic susceptibility, B. aerius KS 8 exhibited a pattern of sensitivity toward norfloxacin, amoxicillin, and clavulanic acid. For pot trials with cauliflower under laboratory conditions, S. sciuri KS 22 showed 3.1 folds increase in shoot length. In the case of tomato, P. rettgeri KS 23 recorded around 1.8 folds increase in shoot length over water-treated control. On the other hand, for cauliflower, around 1.3 folds increase in root length was exhibited by B. aerius KS 8, P. rettgeri KS 23, and E. cloacae KS 29. For tomato, B. aerius KS 8 showed 1.6 folds increase in root length in comparison to control. Under natural conditions, for cauliflower, the highest increase in shoot length was exhibited by P. rettgeri KS 23 and E. cloacae KS 29. Conclusion: Finally, it has been concluded that bacterial strains B. aerius KS 8, S. haemolyticus KS 9, S. sciuri KS 22, P. rettgeri KS 23, and E. cloacae KS 29 exhibited plant growth promotion in pot trials.
