Review ArticleOpen accessIn the abstractDrought and Terminal Heat Stress Effects and Its Management on Wheat Genotypes: A ReviewSantosh Gupta, Prabin Kumar Mahato, Naresh Upadhyaya et al.Wheat (Triticum aestivum) is a vital cereal crop that plays a crucial role in global food security, supplying essential calories and protein to over 80% of the world's population. In recent decades, the effects of climate change, particularly rising temperatures, have raised concerns about Wheat production worldwide. The optimal daytime temperature for Wheat growth during its reproductive stage is around … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 21 Nov 2024 · 8,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Seaweed Extracts on Rice Growth and Tolerance to Salinity, Drought and Blast (Magnaporthe oryzae)Mir Sayeada Alam, Jannatun Nayeema, S. M. Rafiquzzaman, Motaher HossainRice, a primary staple, confronts a multitude of biotic and abiotic stresses. Drought and salinity, exacerbated by climate change and blast disease caused by Magnaporthe oryzae, significantly contribute to yield losses. To tackle the problems, two types of seaweeds-one known as Hypnea musciformis and another unknown-were collected from Saint Martin, Cox's Bazar, Bangladesh and then examined for the potential of … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 May 2024 · 6,506 accessesView PDFCite
Research ArticleOpen accessIn the abstractChlorophyll 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 PDFCite
Research ArticleOpen accessIn the abstractDifferential Gene Transcription in Red Oak (Quercus rubra) Genotypes Resistant to Copper ToxicityProulx Migueal, Paul Michael, Charnelle Djeukam, Kabwe NkongoloToxicity of metals is a major abiotic stressor of plants. Copper (Cu) is one of the most abundant metals in soils from the Greater Sudbury Region (GSR) due to its mining history. Recent studies have described several transporters and chelating proteins involved in copper resistance. Quercus rubra (Red Oak) is a common species that grows in metal contaminated soils in … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 11 Dec 2017 · 8,545 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
EditorialOpen accessIn the abstractAn Opportunity for the Agricultural Sector: The Renewable Energy SourcesRiccardo Testa, Salvatore TudiscaToday, among the most important issue for energy decisions by policymakers, there are security challenges and environmental impacts on climate change and economic aspects. Since the seventies, in fact, global warming and environmental issues have had an increasing importance in international debate, attracting the attention of several scientific studies (Landi and Benelli, 2016). Many of these studies denoted that over … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 6 Sep 2016 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Salt Stress on Ion Balance at Vegetative Stage in Rice (Oryza sativa L.)Kirill V. Azarin, Andrey V. Alabushev, Alexander V. Usatov et al.Rice (Oryza sativa L.) plants were subjected to NaCl stress within 35 days. The shoot dry weight, root dry weight, total survival percentage and contents of inorganic ions in dry samples of stressed plants were measured to identify the physiological adaptive mechanisms by which rice plants at vegetative stage tolerate salt stresses. Laboratory testing of the 10 rice cultivars showed … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 21 Mar 2016 · 7,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Evaluation of Sugarcane Orange Rust for First Clonal Stage of the CP Cultivar Development ProgramDuli Zhao, R. Wayne Davidson, Miguel Baltazar, Jack C. ComstockConsistent development of high-yielding sugarcane (a complex hybrid of Saccharum spp.) cultivars with resistance or tolerance to biotic and abiotic stresses is critical to commercial sugarcane production. Currently, orange rust (caused by Puccinia kuehnii E.J. Butler) is a big challenge for the sugarcane production in Florida, USA. A better understanding of sugarcane genotypic variability in response to orange rust disease … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 1 · 27 Jan 2015 · 7,900 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,135 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant and Photosynthetic Responses in Plants Under Boron Toxicity: A ReviewLucia Guidi, Alberto Pardossi, Elena Degl’Innocenti, Marco LandiBoron (B) is a micronutrient that has long been known essential not only for plants and animals. Otherwise, in crop plants the range of B concentration from essentiality to toxicity appears extremely narrow. Although B deficiency has been well investigated, during recent years many researchers have also investigated boron toxicity effects, making progress in the comprehension of boron transport within … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 5 Jul 2012 · 12,762 accessesView PDFCite
