Research ArticleOpen accessIn the keywordsAgrobacterium-mediated Genetic Transformation in Cucumber (Cucumis sativus L.)A. Vasudevan, N. Selvaraj, A. Ganapathi, C.W. ChoiThe present study was undertaken to develop efficient transformation protocol for cucumber cv. Poinsett 76 using Agrobacterium strain EHA 105. Five-day-old mature cotyledon explants was used for transformation study. The infected explants were co-cultivated for 2 days in MS medium containing BA (1.0 mg Lˉ1). The selection of transformed shoots was carried out in MS medium fortified with BA (1.0 … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 8,901 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsChlorophyll and Protein Changes Observed Post Co-Cultivation of Explants with Agrobacterium Tumefaciens in Soybean (Glycine max L. Merr.)Phetole MangenaAlthough, Agrobacterium-mediated genetic transformation represents a major milestone in agricultural biotechnology for crop improvement against biotic and abiotic stresses. Further insights on the interactions between this bacterium and explants required for in vitro plant regeneration remain scant. This study investigated the changes in chlorophyll content and protein profiles of cotyledonary node explants co-cultivated with A. tumefaciens in soybean. Soybean seeds … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 7 Dec 2022 · 5,046 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMorphogenesis in Tissue Culture of Local Kazakh Cotton VarietiesBishimbayeva Nazira, Yertayeva Bakhyt, Amirova Aigul, Rakhimbayev IzbasarCallus was initiated from hypocotyl and cotyledon explants of seven of commercial Kazakh cotton cultivars on MS medium supplemented with 0,1 mg L-1 2,4-D and 0,5 mg L-1 kinetin. The percentage of callus formation ranged from 64,0 to 91,0% for cotyledons and from 72 to 90% for hypocotyls. Study of morphological heterogeneity peculiarities of metamorphosis and histological structure of calli … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 12 Jul 2017 · 7,171 accessesView PDF Cite

Case ReportOpen accessIn the abstractSome Biological Characteristics and Prediction of Sheep Productivity at Different Variants of Breed SelectionKolosov Yuri A., Klimenko Aleksander I., Vasilenko Vyacheslav N. et al.The paper presents the findings on the morpho structural diversity of sheep placenta, depending on such factors as age, exterior and physique characteristics, breeds, ewes prolificacy that are fundamental in assessing progeny viability. The experiment involved the ewes of the Caucasian and North Caucasian meet-and-wool breeds inseminated by the rams of the same breeds as well as the Texel, Poll … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 1 Dec 2017 · 7,618 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOligoglucans as Elicitors of an Enzymatic Antioxidant System in Zucchini Squash (Cucurbita pepo L.) Seedlings at Low TemperatureAbel Ceron-Garcia, Gustavo Adolfo Gonzalez-Aguilar, Irasema Vargas-Arispuro et al.Abstract: Problem statement: Non-controlled low temperatures affect physiological and biochemical processes leading to Reactive Oxygen Species (ROS) accumulation in plants, which normally are stabilized by the antioxidant system. Superoxide Dismutase (SOD), Ascorbate Peroxidase (APX) and Catalase (CAT) are the most important ROS-detoxification enzymes in stressed plants. Approach: The activity of these enzymes were examined in response to fungal Oligoglucans (OG) … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,306 accessesView PDF Cite
