Research ArticleOpen accessPhrase in the titleComparison of Molecular Markers ISSR, SSR and RFLP to Study the Genetic Variation of Strawberry CultivarsGanies Riza Aristya, Rina Kasiamdari, Muhammad Fauzi Arif et al.Strawberry is grown in Indonesia because it has potential high economic value. The purpose of this study was to investigate relationship of phenetic lineage and genetic variations in 12 strawberry cultivars using three different molecular marker methods, including ISSR, SSR and RFLP. Five primers of ISSR markers were used and they generated 53 bands with 44 polymorphic DNA bands. Percentage … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 19 Mar 2019 · 9,182 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleGenetic Diversity of Some Saudi Barley (Hordeum Vulgare L.) Landraces Based on Two Types of Molecular MarkersMohamed Abdel Hamid Mohamed El-Awady, Adel Ahmed El-Sayed El-Tarras, Salah El-Din El-AssalProblem statement: Very little is known about the genetic diversity and morphological variability present in barley landrace in KSA, a country experiencing loss of biodiversity because of replacement of landraces with modern landraces. Approach: The molecular markers RAPD and ISSR were used as an efficient tools to estimate the intra-and inter-cultivar polymorphism among six barley KSA landraces collected from different … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 12 Mar 2012 · 7,502 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleIdentification of Molecular Markers Differentiating Betula papyrifera and B. pumila Populations from Northern Ontario (Canada)Nastaran Moarefi, Paul Michael, Peter Beckett, Kabwe NkongoloBetula is a polyploid and highly polymorphic genus with several species known to hybridize very readily. This high level of introgression has resulted in hybrid populations where different species are sympatric. The main objectives of the present study were to identify putative hybrids between B. papyrifera and B. pumila in the Greater Sudbury Region (Northern Ontario) and to develop ISSR … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 30 Nov 2018 · 8,057 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEarly Diagnosis of Breast Cancer using Molecular, Biochemical and Pathological MarkersSalah El-Din El-Assal, Adel A. El-Tarras, Samir M. Abd-allaProblem statement: Laboratory diagnosis of breast cancer in most of the hospitals has traditionally been performed using cell culture and the direct hormone receptor assay, which are money and time consuming. Approach: This study was performed in order to direct the attention toward increasing the efficiency of early diagnosis in clinical laboratories at the western region of KSA and Egypt … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 8,056 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMolecular Characterization of Black Bengal and Jamuna Pari Goat Breeds By RAPD MarkersM.A. Rahman, S.M.M. Rahman, M.A. Jalil et al.This experiment was conducted in the Genetics, Breeding and Reproductive Biotechnology Laboratory under Goat and Sheep Production Research Division, Bangladesh Livestock Research Institute (BLRI), Saver, Dhaka, Bangladesh. DNA was extracted from 14 goat breeds and the extracted DNA was observed by gel electrophoresis. Eight goat specific primers were synthesized by ASM-800 DNA synthesizer and screened in the study and all … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 31 Dec 2006 · 9,584 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenetic and Environmental Interactions in Spring Wheat Resistance to Bipolaris Sorokiniana Root Rot in KazakhstanYerlan Dutbayev, Ardak Bolatbekova, Aidana Kharipzhanova et al.Common root rot caused by Bipolaris sorokiniana represents a major constraint to wheat production in Kazakhstan. This study evaluated the resistance of 30 spring bread and durum wheat genotypes under diverse environmental and treatment conditions in two contrasting regions (Almaty and Aktobe) during 2024. The experimental design included three treatment regimes: fungicide application, artificial inoculation with the pathogen, and natural … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 7 Mar 2026 · 1,517 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVariability and Genetic Structure in a Commercial Field of Tequila Plants, Agave tequilana Weber (Agavaceae)Martha Isabel Torres-Moran, Ana Paulina Velasco-Ramirez, Salvador Antonio Hurtado-de la Pena et al.Crops of the tequila plant (Agave tequilana) are produced mainly from offshoots of mother plants in established commercial fields. This propagation method is significant, as it is believed that it facilitates the spread of disease because of the crop’s low genetic variability and is also necessary because it is regulate the use of just that variety in tequila industry. Different … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 22 Feb 2013 · 8,093 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCharacterization of the Genetic Diversity of Peach Cultivars in Taif by RAPD-PCRMohamed A. Nagaty, Salah El-Din El-Assal, Mahmoud M. RifaatProblem statement: Peach genotypes from the Kingdom of Saudi Arabia were not adequately characterized at the biological and molecular levels. This study was carried out to characterize nine peach cultivars growing in Taif (KSA) at the biological and molecular levels. Approach: For the nine peach cultivars studied, flowering and fruiting indices were determined and eight, 10-base primers were used to … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,271 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMolecular Characterization of Banana (AA) Diploids with Contrasting Levels of Black and Yellow Sigatoka ResistanceClaudia Fortes Ferreira, Sebastiao Oliveira Silva, Nivia Paula Damasceno Sobrinho et al.Most banana cultivars are susceptible to many diseases, whereas Sigatoka leads to greatest yield losses. One of the strategies to overcome this disease is thorough banana genetic breeding which consists in the obtainment of improved (AA) diploids which are then crossed with triploids obtaining (AAAB) tetraploid disease resistant bananas also presenting other important agronomic characteristics. The prior knowledge of the … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,652 accessesView PDFCite
