Research ArticleOpen accessEvery word in the titleRoot Elongation, Root Surface Area and Organic Acid by Rice Seedling Under Al3+ and/or H+ StressA. Elisa Azura, J. Shamshuddin, C.I. FauziahProblem statement: Under acidic condition, Al3+ is the most common species in solution. An experiment was conducted to study the effects of Al and/or pH on rice seed germination, root morphology and organic acids release. This study was conducted at ambient temperature in Malaysia. Approach: Two experiments were conducted: (1) Rice seeds undergoing germination were exposed to 0.5 mM CaCl2 … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDifferences in the Response of Diploid and Tetraploid Anthurium andraeanum Seedling Roots to Salt StressYun Zhang, Yongping Zhang, Yongxu Qiao et al.To investigate the effects of salt stress on the growth, development, and endogenous hormone content of roots in diploid and tetraploid seedlings of Anthurium andraeanum, the enhanced salt tolerance was elucidated. The seedlings of A. andraeanum 'Pink champion' were placed at NaCl concentrations of 0, 50, 100, 150, and 200 mmol·L⁻¹. The results indicated that NaCl stress can reduce leaf … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 29 Jan 2026 · 1,776 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effects of Costus Root Aqueous Extract against Schistosomiasis, Liver Damage and Oxidants in Mouse Models of Schistosoma mansoni InfectionAreej Jameel M. AlghabbanSchistosomiasis is one of the major human parasitic diseases in many developing countries that causing chronic ill health in humans. The present work aimed to study the possible curative role of Costus (Saussurea lappa) root extract against Schistosoma mansoni infection induced liver toxicity, cytokines, oxidative stress and DNA damage in mice. 40 adult male micewere divided into four groups (G1, … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 15 Apr 2021 · 6,409 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIncreasing the Strength of Standard Involute Gear Teeth with Novel Circular Root Fillet DesignV. Spitas, Th. Costopoulos, C. SpitasIn this study the idea of spur gear teeth with circular instead of the standard trochoidal root fillet is introduced and investigated numerically using BEM. The strength of these new teeth is studied in comparison with the standard design by discretizing the tooth boundary using isoparametric Boundary Elements. In order to facilitate the analysis the teeth are treated as non-dimensional … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,586 accessesView PDFCite
Review ArticleOpen accessIn the abstractStrigolactones in Plant Stress Adaptation: Mechanisms and Agricultural PotentialHumayra Ferdus, Mahabuba Mostafa, Md. Motaher HossainAbiotic stresses have significant negative effects on the growth, development, and productivity of crop plants, which are critical to global agricultural production and ecosystem stability. Strigolactones (SLs), a family of carotenoid-derived plant phytohormones, have been identified as playing key roles in plant development and adaptive responses to environmental stimuli. Initially recognized as signaling molecules in host-parasite interactions and as symbiotic … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 3 Oct 2026 · 559 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferential Response of Chitosan-Pretreated Rice Cultivars at the Seedling Stage to Drought Stress on Growth and Leaf MetabolitesWasinee Pongprayoon, Sataporn Deeying, Sakchai Hongthong et al.The escalating prevalence of drought stress presents a significant obstacle to global rice cultivation, particularly in arid regions affected by climate change-induced water scarcity. Despite extensive research on the efficacy of exogenously applied chitosan in enhancing drought tolerance across various crops, there remains a gap in understanding the differential responses of chitosan-treated rice seedlings among different cultivars and different chitosan … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 20 Dec 2024 · 5,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Drought Resistance in Spring Wheat (Triticum aestivum L.) Through Chelated Zinc Seed Treatment: An Experimental StudyBekzak Amantayev, Gulden Kipshakbayeva, Arysgul Turbekova et al.Climate change-induced drought is a significant threat to global food security, particularly affecting wheat yields. Despite various strategies to enhance drought resistance in crops, the effectiveness of chelated Zinc (Zn) as a seed treatment agent remains underexplored, especially in the early stages of wheat ontogenesis. This study aims to fill this gap by evaluating the effectiveness of zinc as a … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 26 Sep 2024 · 4,414 accessesView PDFCite
