“…Canna indica is currently being studied as a potential option for CW [13]. When compared to Phragmites australis, a commonly utilized plant for CWs, the key benefit of the Canna plant is its high biomass production with a fast development rate [8]. Because fast-growing plants with huge roots are favourable for nitrifying bacteria to improve nitrification, the biofilm's surface area is increased by their quick growth rate and large biomass [18].…”

“…Hydraulic loading rates, water retention time, water depth, CW design and construction, and feeding mode are all important operational factors that influence CW treatment performance [2]. CWs are getting more and more popular as a treatment option for a variety of wastewaters, including industrial, agricultural, and household wastewaters, landfill leachate, and stormwater runoff [1,[6][7][8]. Several studies have shown that these systems are effective at removing carbon, nitrate, phosphate, and heavy metals [9,10].…”

This article reviews investigations in which Canna indica was utilized in constructed wetlands (CW) for wastewater treatment of a variety types. It is strongly urged that ornamental flowering plants be used in CWs as monoculture or mixed species to improve the appearance of CWs whilst still treating wastewater. Plants play important roles in CWs by giving the conditions for physical filtration of wastewater, a large specific surface area for microbial growth, and a source of carbohydrates for bacteria. They absorb nutrients and integrate them into plant tissues. They release oxygen into the substrate, establishing a zone in which aerobic microorganisms can thrive and chemical oxidation can occur. They also provide wildlife habitat and make wastewater treatment system more visually attractive. The selection of plant species for CW is an important aspect during the CW design process. Canna indica’s effectiveness in CWs has shown encouraging results for eliminating contaminants from wastewater. There is still a scarcity of information on the mechanisms involved in removal of specific contaminants such as pharmaceuticals, personal care products, hormones, pesticides and steroids and their potential toxicity to the plants. Therefore, this paper reviews some published information about the performance of Canna indica in wastewater treatment, as well as potential areas for future research.

“…Constructed wetlands depend on biological processes like plant assimilation and biodegradation, chemical processes like adsorption and precipitation, and physical processes like filtration and sedimentation for the treatment of wastewater (Pinninti et al, 2022). Plants play a significant role in CWs processes.…”

In recent times, interest in decentralized sanitation alternatives, especially constructed wetlands (CWs), has spiked because of the need for wastewater treatment systems that allow effluent reuse, all in an effort to try and meet the rising demand for new water sources. Therefore, due to the increase in research in the subject area, the present study aimed to identify the research trends and prevailing themes in the existing literature on constructed wetlands as domestic wastewater treatment systems. A scientometric methodology was adopted in the study. The scientometric review was conducted using the VOSviewer and Citespace software. A total of 68 peer-reviewed journal articles were quantitatively analyzed using Various methods such as co-authorship analysis, co-citation analysis, and keyword analysis. Constructed wetlands were found to be very effective and efficient in pollutant removal, nutrient recycling, and water recycling through the identified clusters. The advancement and modification of CWs to make them better at treating new toxins was a welcome notion in the field. However, the lack of extensive collaboration among researchers needs to be improved for the betterment of the field through ideas and information exchange. The study was limited because it was conducted using the Scopus database and only focused on domestic wastewater. Therefore, future research can be centred around other types of wastewater using databases other than Scopus.

“…These studies have also evaluated the utilization of various resources and the breeding of varieties. Studies on C. indica focus on its ability to purify heavy metals, such as copper, nickel, zinc, cadmium ( Dong et al, 2019 ), chromium, and lead, and remove nitrogen and phosphorus from sewage water ( Pinninti et al, 2021 ). A few studies have reported on the genomes of C. edulis and C. indica .…”

Canna edulis Ker-Gawl and Canna indica L. are species belonging to the Cannaceae family and both have a very high economic value. Here, we aimed to assemble genomes of C. edulis and C. indica at the chromosome level to generate a reference genome for the Cannaceae family. We also comparatively analyzed the genomes of C. edulis and C. indica and examined the molecular mechanisms responsible for the remarkable differences in plant characteristics in C. edulis varieties. Our results indicated that genome-wide duplication events had recently occurred in C. edulis and C. indica. The comparative analysis of the genomes of C. edulis and C. indica revealed that C. edulis exhibited a remarkable level of replication of genes in the starch and sucrose metabolic pathways, especially during sucrose hydrolysis. This finding is consistent with the fact that the starch content of the C. edulis tuber is higher than that of C. indica. Simplified genome re-sequencing revealed the population structure of 241 C. edulis genes, and a genome-wide association study of leaf traits revealed the location of key genes related to leaf color and morphology. These findings extend our understanding of Cannaceade at the molecular level, and provide an effective theoretical basis for further study and utilization of Cannaceae plants.
