Enset (Ensete ventricosum) is a multipurpose crop extensively cultivated in southern and southwestern Ethiopia for human food, animal feed, and fiber. It has immense contributions to the food security and rural livelihoods of 20 million people. Several distinct enset landraces are cultivated for their uses in traditional medicine. These landraces are vulnerable to various human-related activities and environmental constraints. The genetic diversity among the landraces is not verified to plan conservation strategy. Moreover, it is currently unknown whether medicinal landraces are genetically differentiated from other landraces. Here, we characterize the genetic diversity of medicinal enset landraces to support effective conservation and utilization of their diversity. We evaluated the genetic diversity of 51 enset landraces, of which 38 have reported medicinal value. A total of 38 alleles across the 15 simple sequence repeat (SSR) loci and a moderate level of genetic diversity (He = 0.47) were detected. Analysis of molecular variation (AMOVA) revealed that only 2.4% of the total genetic variation was contributed by variation among the medicinal and non-medicinal groups of landraces, with an FST of 0.024. A neighbor-joining tree showed four separate clusters with no correlation to the use-values of the landraces. Except for two, all “medicinal” landraces with distinct vernacular names were found to be genetically different, showing that vernacular names are a good indicator of genetic distinctiveness in these specific groups of landraces. The discriminant analysis of the principal components also confirmed the absence of distinct clustering between the two groups. We found that enset landraces were clustered irrespective of their use-value, showing no evidence for genetic differentiation between the enset grown for ‘medicinal’ uses and non-medicinal landraces. This suggests that enset medicinal properties may be restricted to a more limited number of genotypes, might have resulted from the interaction of genotype with the environment or management practice, or partly misreported. The study provides baseline information that promotes further investigations in exploiting the medicinal value of these specific landraces.

Abstract Background: Enset (Ensete ventricosum (Welw.) Cheesman) is a staple food for more than 20 million Ethiopians and only cultivated in the native indigenous farming systems of Ethiopia. In contrast to other cultivated species in the Musaceae family, enset has been relatively little studied at the molecular level. Application of advanced molecular genetic techniques requires rapid extraction of DNA of high quality and quantity. Fresh, lyophilized tissues, as well as tissues stored in liquid nitrogen are mainly preferred to avoid DNA degradation, thus most of the DNA extraction protocols recommend these types of tissues as starting material. However, such sample processing techniques are difficult to utilize in many developing countries and at collection sites of many endemic plant species, underutilized or orphan crop species like enset. These situations necessitate the development of alternative protocols for leaf preservation and optimized methods for isolating high-quality DNA from dried or preserved leaf samples. Results: In this study, three different leaf preservation and two DNA extraction methods were compared. Fresh young leaf tissue was preserved using the minor modified saturated NaCl-CTAB solution, silica gel or 96% ethanol at ambient temperature for more than 35 days. Subsequently, DNA was extracted using either the DNeasy Plant Mini Kit or the CTAB method. As compared to silica gel and 96% ethanol, the minor modified saturated NaCl-CTAB solution preserved the quality, quantity, and integrity of enset genomic DNA. This method consistently produced genomic DNA of high-quality and quantity at affordable cost. The DNeasy Plant Mini Kit method was found to be more efficient than the standard CTAB method, being faster and producing genomic DNA of higher quality. Conclusions: Using saturated NaCl-CTAB solution is an accessible, efficient, scalable, and inexpensive way to preserve enset leaves during collection and transportation. The preservation protocol was validated for leaf tissues of all cultivated and wild enset, and Entada landraces. Genomic DNA of high quality and quantity was obtained from preserved enset leaves, which can be used for further downstream applications including PCR and sequencing.

Drug-induced liver injury (DILI) is one of the cumbersome health-related problems which render approximately 50% of liver failure and patients to receiving liver transplantation every year. Antituberculosis drugs such as isoniazid and rifampicin are potentially rendering hepatotoxicity. Ensete ventricosum (Welw.) Cheesman is an herbaceous perennial plant that contributes to the indigenous ethnomedicinal values for the society. This study aimed to investigate the hepatoprotective effect of corm of Ensete ventricosum (Welw.) Cheesman extracts against isoniazid and rifampicin induced hepatotoxicity in Swiss albino mice. The study was conducted on 30 Swiss albino mice randomly allocated into five groups. Group I, group II, group III, group IV, and group V were the groups in which mice were given distilled water, only isoniazid and rifampicin, isoniazid and rifampicin along with 200 mg/kg corm of Ensete ventricosum (Welw.) Cheesman extract, isoniazid and rifampicin along with 400 mg/kg corm of Ensete ventricosum (Welw.) Cheesman extract, and isoniazid and rifampicin along with silymarin per oral per day, respectively. On the 30th day of the experiment, mice were sacrificed after anesthetized, and blood was drawn for the liver function test, and the liver was also taken from each experimental mouse for histopathological evaluation. Data were entered into EpiData version 3.1 subsequently exported to SPSS version 25 for analysis by using one-way ANOVA. Plasma alanine aminotransferase (ALT) levels, aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin (TBIL) of group II mice were significantly ( p < 0.05 ) elevated as compared to group I. The group of mice treated with a corm of Ensete ventricosum (Welw.) Cheesman at a dose of 400 mg/kg (group IV) and silymarin100 mg/kg (group V) showed a significant ( p < 0.05 ) decrease in ALT, AST, ALP, and TBIL as compared to the group II. The liver section of group II showed a change in liver architecture; however, these deformities were not noticed in group IV mice. The result showed corm of Ensete ventricosum (Welw.) Cheesman extract has a very promising hepatoprotective potential against isoniazid and rifampicin induced liver injury.

Abstract BackgroundEnsete ventricosum is an important food crop consumed in the form of Bulla and Kocho mainly used in the southern parts of Ethiopia for their sustainable livelihood and ensuring food security. Besides, it is used as animal feed, as well as a source of medicine and fiber. This study was undertaken on the morphological traits among the Enset (Ensete ventricosum) landraces and cultural use of the landraces for the livelihood of people in Mareka woreda, Dawro zone, southern Ethiopia. The study was carried out in purposively selected four kebeles of Mareka district’s Dawro zone.ResultsA total of 145 (20 purposively selected key informants and 125 randomly selected respondents) were interviewed using semi-structured interviews, and field observation was also used to collect ethnobotanical data. The morphological traits were measured according to IBPGR (International Board for Plant Genetic Resources) descriptors for Enset. The data were analyzed by using computer software SPSS v 16.0 as well as Excel 2010 spreadsheet. A total of 33 Enset landraces were identified from the study area. Farmers gave the name for their landraces based on the morphological trait and sources of planting material. Identified landraces were grouped into five clusters based on their morphological trait variability. Mean plant height, pseudostem height, and circumference, leaf size, and numbers have significant differences among clusters. Cluster number five had the highest mean in plant height, pseudostem height, and circumference and cluster number three had the lowest mean. The highest landrace richness was recorded from Ocha (3.18) while the lowest was from Guta (2.56). The most abundant landraces were Amiya, Hoeya, Boza, Yaka, Bothena, Ontha, Adinona, Shasha, and Keteriya in the Mareka district.ConclusionsThis study confirmed that the Dawro zone is rich in diversity of Enset, however, reduction in production and loss of some landraces was observed because of different factors. Therefore, attention must be given to the conservation and maintenances of Enset landraces by all the concerned bodies.
