Research ArticleOpen accessIn the keywordsAccumulation and Effect of Manganese on Chloroplasts and Antioxidant Responses in Arabidopsis ThalianaJun Xing, Xue Yang, Cailing YuanIn this study, 5-day-old seedlings of Arabidopsis thaliana were exposed to 0, 0.5, and 1.0 mmol/L MnCl₂ for 6 days by using three independent biological replicates. The results indicated that Mn content in roots exhibited a dose-dependent increase with rising external Mn supply. The elevated Mn levels led to significant reductions in the nutrient content of K, Ca, Na, and … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 18 Jul 2026 · 836 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTrace of Salinity of Sodium Chloride with Outcome on Enhancement Features of HerbageSona Pazdar, Saeid Eslamian, Kaveh Ostad-Ali-Askari et al.Salinity has a variety of salts, one of which is salinity of sodium chloride. Different plants react differently to salinity and their performance will vary according to their resistance, which after all the treatments, chlorophyll was measured. Depend on the outcomes of salinity consequences on native herbage; herbage features such as relative chlorophyll and chlorophyll fluorescence were decreased. Also, salinity … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 26 Jun 2019 · 7,044 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Investigation of Organelle Genomes of Extra Nuclear Sunflower Mutants with Variegated PhenotypeIrina Dremuk, Nikolay Kozel, Mariya Logacheva et al.The comparative analysis of complete chloroplast and mitochondrial DNA sequences of the original inbred line 3629 and three extra nuclear mutant lines variegated-1, variegated-15, variegated-17, obtained by the N-nitroso-N-methylurea induced mutagenesis, was done. The studied mutant lines were presented two different phenotypes with diverse chlorophyll content: Pale/green mutant line variegated-17 with 1.8% relative (to 3629 line) chlorophyll content in mutant … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,638 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVariability of Chloroplast DNA of Extranuclear Sunflower MutantsMarkin Nicolay, Aieksandr Usatov, Maria Logacheva et al.A comparative analysis of full-genome sequences of chloroplast DNA (cpDNA) of the original inbred line 3629 and three extranuclear mutants, which were obtained by the method of mutagenesis induced with N-nitroso-N-methylurea (NMU) and characterized by different level of chlorophyll insufficiency (en:chlorina-7-yellow-green leaves; chlorophyll content (a + b)-67.8% with respect to the line 3629, variegated-10-leaves with white zones; chlorophyll content (a … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Mar 2016 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEVALUATION FOR SALT STRESS TOLERANCE IN TWO STRAWBERRY CULTIVARSW. Al-Shorafa, A. Mahadeen, K. Al-AbsiSalt stress conditions have been found to destroy the vital physiological process in plant where slower cell division and cell enlargement or both and limit mineral nutrient uptake with clearly nutritional imbalance. A greenhouse pot experiment was carried out at Agricultural Research Station, Mu’tah University, Jordan to evaluate growth responses and mineral composition of two strawberry cultivars to salt stress … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 14 Apr 2014 · 7,700 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEFFECTS OF UV-B ON PHOTOSYNTHETIC PARAMETERS, LIPID PEROXIDATION, FLAVONOIDS AND GROWTH TRAITS OF CONOCARPUS LANCIFOLIUS (ENGL.)Patrice Suleman, Amina Redha, Mohamad Afzal, Redha Al-HasanConocarpus lancifolius is a perennial ornamental plant adapted to the semi-arid conditions of Kuwait. It accumulates most of its biomass during the stressful summer conditions which includes UV-B irradiation. The study evaluated equivalent UV-B irradiation intensities that plants would normally experience sometime during the course of a year in Kuwait. Leaf area, plant height, photosynthetic parameters, Lipid Peroxidation (LP) and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 23 Dec 2013 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAntagonistic Effects of Fertilizer on Photochemical Efficiency of Hibiscus cannabinus L. (Kenaf) Planted on Beach Ridges Interspersed with Swales SoilMohd-Hazimy Yusoff, Hazandy Abdul-Hamid, Arifin Abdu et al.Problem statement: Hibiscus cannabinus L. or Kenaf is a highly productive, warmseasonal C3 annual crop and is one of the potential candidates to substitute kenaf fiber as raw product for pulp and paper production. It survives well on less fertile soils including those of Beach Ridges Interspersed with Swales (BRIS) soil. Approach: The objective of this study was to determine … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 19 Sep 2011 · 8,512 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCharacteristic Study of the Marine Algae Sargassum sp. on Metal AdsorptionA. Saravanan, V. Brindha, Soundarajan KrishnanProblem statement: Biomass of brown marine macro algae is a biological resource that is available in large quantities and can form a good base for the development of biosorbent material. Approach: Algae have been found to be potentially suitable biosorbents because of its cheap availability, both in fresh or salt water, relatively high surface area and high binding affinity. Results: … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCorn (Zea Mays L.) Plant Characteristics and Grain Yield Response to N Fertilization Programs in No-Tillage SystemKesi Liu, Pawel WiatrakProblem statement: Nitrogen application timing and Nitrogen (N) rate are two important factors to influence corn production in No-Tillage (NT) system, but N recommendations may need to be revised due to insufficient rainfall in dryland rain-fed environment. Approach: This study was to determine the effects of two N application timing (planting and split application at planting and V6 corn growth … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 25 Mar 2011 · 8,343 accessesView PDFCite
