Research ArticleOpen accessIn the keywordsMapping QTLs Linked to Physio-Morphological and Plant Production Traits under Drought Stress in Rice (Oryza sativa L.) in the Target EnvironmentS. Michael Gomez, S. Satheesh Kumar, P. Jeyaprakash et al.Drought stress is a major constraint for rice (Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions (QTLs) contributing in drought resistance will help to develop rice cultivars suitable for water-limiting environments through marker-assisted breeding. QTLs linked to physio-morphological and plant production traits under drought stress in the field were mapped by evaluating 177 F6 recombinant … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 14,471 accessesView PDF Cite

Review ArticleOpen accessIn the abstractGoats’ Litter Size Concerning Bone Morphogenetic Protein 15 Gene VariationsTebogo Letsukulo Percy Thepa, Thobela Louis Tyasi, Jones Ng’ambiBone morphogenetic protein 15 (BMP15), a member of the transforming growth factor-β (TGF-β) superfamily, plays essential roles in follicular development and ovulation. Single nucleotide polymorphisms (SNPs) in the BMP15 gene have been associated with litter size in multiple livestock species, yet no comprehensive systematic review has synthesized findings across goat breeds. This systematic review aimed to evaluate the association between … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 18 Feb 2026 · 1,405 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic 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 PDF Cite

Research ArticleOpen accessIn the abstractQuantitative Trait Loci Analysis of Novel Fusarium Head Blight Resistance in Tokai 66Y. Yen, A.M. H. Ibrahim, S. Malla et al.Problem Statement: Identification of Quantitative Trait Loci (QTLs) in durable resistant genotype is important for marker-assisted breeding. The study was conducted to identify QTLs linked to FHB resistance in 'Tokai 66', a Japanese genotype. Approach: A cross was made between Tokai 66 and Jagalene and the single seed descend was used to advance the population. The F2:4 and F2:5 populations … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,091 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharacterization of Bovine Calpastatin Gene in Nelore Cattle Using Polymerase Chain Reaction-Restricted Fragment Length PolymorphismsAlireza Majidi, Jothi Malar Panandam, Awis Qurni Sazili, Siti Shapor SirajProblem statement: In beef cattle production, of meat quality and carcass traits are important. Traditionally beef cattle breeding programs unfortunately are time consuming and also recording of carcass and growth traits need heavy cost, Approach: Marker Assisted Selection (MAS) should be utilized in beef herds, along with economically important phenotypic traits, for genetic progress to made with respect to improving … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 7,329 accessesView PDF Cite
