However, fungicides and plant root secretions may impact the diversity and abundance of microbiota structure and enzymatic activities in the plant rhizosphere. In this study, we analyzed soil samples from the rhizosphere of four cannabinoid-rich hemp (Cannabis sativa) cultivars (Otto II, BaOx, Cherry Citrus, and Wife) subjected to three different treatments (natural infection, fungal inoculation, and fungicide treatment). DNA was extracted from the soil samples, 16S rDNA was sequenced, and data were analyzed for diversity and abundance among different fungicide treatments and hemp cultivars. Fungicide treatment significantly impacted the diversity and abundance of the hemp rhizosphere microbiota structure, and it substantially increased the abundance of the phyla Archaea and Rokubacteria. However, the abundances of the phyla Pseudomonadota and Gemmatimonadetes were substantially decreased in treatments with fungicides compared to those without fungicides in the four hemp cultivars. In addition, the diversity and abundance of the rhizosphere microbiota structure were influenced by hemp cultivars. The influence of Cherry Citrus on the diversity and abundance of the hemp rhizosphere microbiota structure was less compared to the other three hemp cultivars (Otto II, BaOx, and Wife). Moreover, fungicide treatment affected enzymatic activities in the hemp rhizosphere. The application of fungicides significantly decreased enzyme abundance in the rhizosphere of all four hemp cultivars. Enzymes such as dehydrogenase, dioxygenase, hydrolase, transferase, oxidase, carboxylase, and peptidase significantly decreased in all the four hemp rhizosphere treated with fungicides compared to those not treated. These enzymes may be involved in the function of metabolizing organic matter and degrading xenobiotics. The ecological significance of these findings lies in the recognition that fungicides impact enzymes, microbiota structure, and the overall ecosystem within the hemp rhizosphere.}, number={11}, journal={INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, author={Xu, Junhuan and Knight, Tyson and Boone, Donchel and Saleem, Muhammad and Finley, Sheree J. and Gauthier, Nicole and Ayariga, Joseph A. and Akinrinlola, Rufus and Pulkoski, Melissa and Britt, Kadie and et al.}, year={2024}, month={Jun} }

The wicking method has been employed to select the most hydrophilic sample of fabric upon irradiation. The micrographs obtained by scanning electron microscopy, transmission electron microscopy, and high-resolution transmission electron microscopy indicated the erosions occurring at the surface of nano-calcite after UV light irradiation, maintaining the crystallinity of the photocatalyst. The surface charge has been measured for as-fabricated and irradiated nano-calcite @ PF for the development of high negative zeta potential after UV light irradiation (−24.6 mV). The irradiated nano-calcite @ PF exhibited a significant change in its contact angle, and the wetting property was enhanced to a considerable extent on UV (55.32°) and visible light irradiation (79.00°) in comparison to as-fabricated nano-calcite @ PF (137.54°). The irradiated samples of nano-calcite @ PF delineated the redshift in harvesting of solar spectrum, as revealed by diffuse reflectance spectroscopy comparative spectra. Additionally, the band gap of untreated nano-calcite was found to be 3.5 eV, while UV- and visible light-irradiated PF showed a reduction in band gap up to 2.95 and 3.15 eV upon UV and visible light irradiation. The photocatalytic efficiency of mesoporous nano-calcite was evaluated by photocatalytic degradation of imidacloprid as the probe pollutant. Higher solar photocatalytic degradation of imidacloprid (94.15%) was attained by UV light-irradiated nano-calcite @ PF. The time-resolved photoluminescence study has verified the high photocatalytic activity of UV light-irradiated nano-calcite @ PF for the generation of high concentration of hydroxyl radicals. The highly efficient reusability of a nano-calcite-based solar photocatalytic reactor has been observed for 10 cycles of treatment of imidacloprid bearing wastewater. The enhanced photocatalytic activity of UV light-exposed (20 min), superhydrophilic, nano-calcite @ PF for mineralization of pollutants suggests it to be an efficient solar photocatalyst for environmental applications.}, number={39}, journal={ACS OMEGA}, publisher={American Chemical Society (ACS)}, author={Ashar, Ambreen and Qayyum, Ayesha and Bhatti, Ijaz Ahmad and Aziz, Humera and Bhutta, Zeeshan Ahmad and Abdel-Maksoud, Mostafa A. and Saleem, Muhammad Hamzah and Eletmany, Mohamed R.}, year={2023}, month={Sep}, pages={35722–35737} }

HYBRIDS 'MAMMOTH'}, volume={53}, ISSN={["2076-0906"]}, DOI={10.21162/pakjas/16.3769}, abstractNote={Gladiolus (Gladiolus L. hybrids), one of the most popular bulbous cut flowers of the world, has the problem of shorter vase life due to vascular occlusion by bacteria. Stem blockage in cut flowers is generally caused by bacterial proliferation along with their decay products (Teixeira-da-Silva, 2003). Bio-control through bacteria represent a potential alternative management approach (Jetiyanon and Kloepper, 2002) and may help in developing an organic method for effectively controlling detrimental microbes in the vase solutions (Carlson et al., 2015). The bio-control agents are used for biological management of pests to control a specific microbe (Shanmugam et al., 2011; Sajjad et al., 2014). Among bacterial antagonists, Pseudomonas fluorescens is most effective against a wide range of plant pathogens infecting different plants such as carnation, bean, radish, cucumber, tomato, and tobacco (van Loon et al., 1998), while P. fulva has extended vase life of cut zinnia stems (Carlson et al., 2015). Moreover, Burkholderia cepacia and Bacillus spp. (spore forming Gram-positive bacteria) have effectively been used to control plant diseases (Kloepper et al., 2004). Use of compatible and multiple bio-control agents in various groups also helps to control plant diseases, such as combinations of bacteria (Raupach and Kloepper, 1998; Shanmugam et al., 2002), fungi (Paulitz et al., 1990), bacteria and fungi (Duffy et al., 1996), yeasts (Janisiewicz, 1996), and bacteria and yeast (Janisiewicz and Bors, 1995). An experiment was conducted to compare different beneficial bacterial strains for their efficacy to control detrimental bacteria in vase solutions with gladiolus stems. There is dire need to develop organic preservatives for keeping flower organic grown without chemicals until end of vase life. However, there are currently no effective organic preservatives available in the market and those available are not effective (Ahmad et al., 2014). Organic carbohydrate source and acidifier are available but organic biocides are not available. Therefore, this study was conducted to elucidate the effect of bio-control bacterial strains, some of which have been proved effective for various agronomic crops, in controlling detrimental bacteria in vase solutions and effect on the postharvest water relations and quality characteristics of cut gladiolus. Moreover, the findings of the study would help develop an organic floral preservative to be used for handling organically grown cut flowers. Pak. J. Agri.
