“…Few studies reported the association of various endophytic bacteria and fungi with different parts of C. speciosus plant [44][45][46][47][48][49] . These research works also showed that the endophytes had effect on plant growth [44][45][46][47] . Some studies showed that the endophytic microorganisms produced pharmacologically active substances, such as antifungal and anti-cancer compounds 48,49 .…”

Costus speciosus (J. Koenig) Sm., commonly known as crepe ginger, is primarily used as an ornamental plant worldwide. The aim of this research was to study the phytoconstituents of locally collected C. speciosus plant samples and test their antimicrobial effect against selected bacterial strains. Phytochemical analysis showed the presence of alkaloids, flavonoids, steroids, phenolic compounds, tannins, glycosides, and cardiac glycosides in the extracts. The extracts displayed variable degrees of antibacterial activity against the microorganisms in a bioautography experiment based on thin-layer chromatography. All the extracts showed activity against S. aureus, and none showed any activity against P. aeuroginosa. The ethanol and ethyl acetate extracts from the plant leaf and stem showed efficacy against S. typhi and B. subtilis, while the ethyl acetate extracts prevented the growth of S. pneumoniae. Only the ethanol extract from plant leaves had a negligible effect on K. pneumoniae. Bangladesh J Microbiol, Volume 39, Number 2, December 2022, pp 46-52

“…Lettuce growth promoted the abundance of 17 bacterial reads, and four of the promoted genera have been associated with plant symbiotic or protective abilities ( Rhodoferax , Fluviicola , Cytophaga , and Knoellia) . Rhodoferax members can degrade chemical herbicides [ 71 ], and Fluviicola is a common member of the rice rhizosphere [ 56 ]. Bacteria within the genus Cytophaga are present in the barley rhizosphere, and may contribute to the turnover of carbon, phosphorus, and nitrogen in soil ecosystems [ 72 ].…”

Soil microbiome disruption reveals specific and general plant-bacterial relationships in three agroecosystem soils

Soil microbiome disruption methods are regularly used to reduce populations of microbial pathogens, often resulting in increased crop growth. However, little is known about the effect of soil microbiome disruption on non-pathogenic members of the soil microbiome. Here, we applied soil microbiome disruption in the form of moist-heat sterilization (autoclaving) to reduce populations of naturally occurring soil microbiota. The disruption was applied to analyze bacterial community rearrangement mediated by four crops (corn, beet, lettuce, and tomato) grown in three historically distinct agroecosystem soils (conventional, organic, and diseased). Applying the soil disruption enhanced plant influence on rhizosphere bacterial colonization, and significantly different bacterial communities were detected between the tested crops. Furthermore, bacterial genera showed significant abundance increases in ways both unique-to and shared-by each tested crop. As an example, corn uniquely promoted abundances of Pseudomonas and Sporocytophaga, regardless of the disrupted soil in which it was grown. Whereas the promotion of Bosea, Dyadobacter and Luteoliobacter was shared by all four crops when grown in disrupted soils. In summary, soil disruption followed by crop introduction amplified the plant colonization of potential beneficial bacterial genera in the rhizosphere.

Whereas the promotion of Bosea, Dyadobacter and Luteoliobacter was shared by all crops grown in all disrupted soils. In summary, soil disruption followed by crop introduction amplified plant-mediated selection of plant benefiting bacterial genera.
