Genetic Diversity Analysis of faba bean (Vicia faba L.) Based on EST-SSR Markers

Agricultural Sciences in China 2011年第6期10卷 838-844页

faba bean （Vicia faba L.）, one of the most important legumes in the world, evolved different types of cultivars due to its partial cross-pollination. The development of simple sequence repeat （SSR） markers from expressed sequence tags （EST） provided a useful tool for investigation of its genetic diversity. The purpose of the present study was to investigate the genetic diversity of faba bean from China and Europe using EST-SSR markers. 5 031 faba bean ESTs from the NCBI database were downloaded and assembled into 1 148 unigenes. A total of 107 microsatellites in 96 unigenes were identified, indicating that merely 8.36% of sequences contained SSRs. The most abundant SSR within faba bean was tri-nucleotide repeat motif, and among all the tri-nucleotide repeats, the motif AAG/CTT was the most abundant type. Based on these results, 11 EST-SSR markers were used to assess the genetic diversity of 29 faba bean cultivars from China and Europe with two to three alleles per locus. The polymorphism information content value ranged from 0.0644 to 0.4278 with an average of 0.2919. Principal coordinate analysis （PCA） and phylogenetic clustering based on these 11 EST-SSR markers distinguished these cultivars into different groups. The results indicated that faba bean in China had a narrow genetic basis, and the additional sources of genetic cultivars/accessions should be introduced to enhance the genetic variability. The results of this study proved that the EST-SSR marker is very effective in evaluation of faba bean germplasm.

Nanoparticle Treatments Based on Zinc Oxide and Moringa oleifera Leaf Extracts Alleviate Salinity Stress in faba bean (Vicia faba L.)

Salinity stress limits crop growth and productivity, including legumes in various regions worldwide. The impact of foliar-applied zinc nanoparticles (ZnNPs) and combined zinc nano-loaded with moringa extracts (ZnONPs) on salt tolerance in faba beans (cultivar, Giza-716) grown under saline soil (50 and 100 mM NaCl) was investigated. Moringa oleifera extract has been used as a chelating agent to synthesize zinc oxide nanoparticles. The crystalline structure, morphology, and chemical composition of ZnO nanoparticles were studied using various characterization techniques, including UV-visible spectroscopy (UV), Fourier Transform Infrared Analysis (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Morphological, chemical, and biochemical parameters of plants at 60 and 90 days after sowing were assessed. Salinity stress caused a remarkable reduction in growth traits, photosynthetic pigments and proline levels of the faba bean. Foliar spray with ZnNPs and ZnONPs on faba bean grown under saline soils promoted plant growth parameters (i.e., shoot length, numbers of leaves, relative water content, shoot and roots fresh and dry weights), photosynthetic pigments (Chl a, b, total chlorophyll, and carotenoids), proline and mineral elements (Na+, K+, Ca2+, and Zn2+) compared to control. However, at 100 mM NaCl, there were no significant variations in the mentioned parameters. This study suggested that there is potential for foliar spraying with ZnNPs and ZnONPs in improving growth parameters, photosynthesis efficiency and biochemical aspects of faba bean plants under saline conditions.

Assessment of Factors Influencing Chocolate Spot (Botrytis fabae) Disease Epidemics of faba bean (Vicia faba L.) at Tach Gayint District in North Western Ethiopia

Open Journal of Ecology 2022年第7期12卷 391-406页

作者： Merkuz Abera Meseret Semagn Plant Sciences College of Agriculture and Environmental Sciences Bahir Dar University Bahir Dar Ethiopia

faba bean (Vicia faba L.) is one of the oldest domesticated food legumes that have been cultivated for at least 5000 years. It is a multi-purpose crop that plays an important role in the socio-economic life of farming communities in Ethiopia. Chocolate spot disease, caused by Botrytis fabae is one of the yield limiting factors of this crop resulting in yield losses up to 68% in Ethiopia. A field survey was conducted in Tach Gayint district South Gondar Administrative Zone during the 2020/2021 main cropping season to assess the importance of the chocolate spot disease of faba bean. A total of 60 faba bean farmer fields were assessed in six (6) Kebele Administrations and most farmer fields were affected by chocolate spots. But the status of disease incidence and severity was varied. Significant differences among locations were observed due to altitude, soil type, planting density, date of planting, crop growth stages and farm history of the fields. Independent variables like Altitude, farm history, crop growth stage, date of planting and planting density were significantly associated with both disease incidence and severity when entered first and last into a model. The finding indicates that the lowest plant density and late planting of the crop reduce the incidence and severity of the disease.
