Research ArticleOpen accessIn the abstractSocial Capital Concerning a Conservation of Sweet Wild Trees (Phak Whanpa) in a Northeastern Thailand CommunityPhiphaporn Ravipolsadtanan, Worapol Aengwanich, Prasopsuk LittidetProblem statement: Thai people favored to eat Sweet Wild Trees (Phak Whan Pa). The wild trees naturally grew quite slowly in the forests. Their leaves, eaten as vegetables, could not meet market demand nationwide. Seedling was difficult and people were not interested in planting them. Support from government and/or public sectors was slow. Those were the causes for shortages of … …Journal of Social Sciences, Vol. 5, Issue 1 · 31 Mar 2009 · 7,794 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeed Germination and Seedling Survival of Spartina alterniflora LoiselPatrick D. Biber, John D. CaldwellSpartina alterniflora (smooth cordgrass) is a widespread intertidal salt marsh plant that is frequently used in coastal restoration projects. Seeds collected in 2004 were tested for seed germination and seedling survival after 6 months of cold seed storage to determine differences among collection locations (experiment 1). Seeds collected in 2005, after Hurricane Katrina, were tested for seed germination and seedling … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,704 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGamma Radiosensitivity Study on Chili (Capsicum annuum)Shairul Rizdiyandi Omar, Osumanu Haruna Ahmed, Shaharudin Saamin, Nik Muhamad Ab. MajidInduced mutation by gamma irradiation has been found to be a very useful technique for crop improvement. Apart from this, the proper use of induced mutation in plant breeding has become a profitable approach. This investigation was carried out to determine the LD50 and effect of gamma rays on germination, plant height, survival percentage, root length, root dry weight and … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 9,033 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGamma Radiosensitivity Study on Long Bean (Vigna sesquipedalis)Ellyfa Kon, Osumanu Haruna Ahmed, Shaharudin Saamin, Nik Muhamad Ab. MajidThis study was conducted to determine the LD50 and effect of gamma ray on germination percentage, plant height, survival percentage, root length, root dry weight and shoot dry weight of seedlings derived from seeds of long bean (Vigna sesquipedalis). Seeds of this crop were treated with 300, 400, 500, 600 and 800 Gy gamma rays at Malaysian Institute of Nuclear … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,596 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHigh Level of Nicotianamine Synthase (NAS3) and Natural Resistance Associated Macrophage Protein (NRAMP4) Gene Transcription Induced by Potassium Nitrate in Trembling Aspen (Populus tremuloides)Karolina M. Czajka, Kabwe NkongoloChanges in gene transcription in response to excess metal concentrations have been reported in many organisms, including yeast, microorganisms and plants. Most investigations on the effects of nickel toxicity in plants use commercial salts whose effects have not been analyzed in detail. The main objective of the present study was to determine the effects of different doses of nickel nitrate … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 15 Jul 2018 · 10,884 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractChanges in Leaf Characteristics with Tree Age in Dryobalanops beccarii Dyer in a Restored Forest of Sarawak, MalaysiaEmilla Yastari LAPOK, ONG Kian Huat, John Keen CHUBO, Patricia KING Jie HungStudy on leaf properties of an endangered dipterocarp tree species, Dryobalanops beccarii, was conducted in a restored forest. The study focused on the morphology, nutrient concentration and gas exchange in well-developed leaves of D. beccarii at different ontogenetic phases. The hypothesis tested that leaf physiological and morphological changes are related to the nutrient concentration level of D. beccarii leaves in … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 25 Sep 2017 · 7,542 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDevelopment, Polymorphism and Cross-Species Transferability of Genomic SSR Markers in Duabanga Moluccana, an Indigenous Tree Species from SarawakKit-Siong Liew, Wei-Seng Ho, Shek-Ling Pang, Julaihi AbdullahIn this study, we used ISSR-suppression methods to develop a set of SSR markers for Duabanga moluccana. It is an indigenous fast growing tropical tree species. A total of 44 SSR regions were identified and specific primer pairs were designed. The SSR motifs contained perfect compound with 24 (54.5%) occurrences, followed by the imperfect compounds with 8 (18.2%), simple perfect … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 26 Jan 2016 · 7,784 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIllumina-Based De Novo Transcriptome Analysis and Identifications of Genes Involved in the Monolignol Biosynthesis Pathway in Acacia koaKazue Ishihara, Eric K.W. Lee, Isabel Rushanaedy, Dulal BorthakurAcacia koa is a leguminous timber tree endemic to the Hawaiian Islands. For breeding projects involved in improving wood quality of A. koa, understanding of genes influencing wood quality is crucial. Therefore, the objective of this study was to identify A. koa genes in the monolignol biosynthesis pathway, which is involved in wood formation and development. In this study, whole … …Current Research in Bioinformatics, Vol. 4, Issue 1 · 6 Aug 2015 · 11,037 accessesView PDF Cite
