Research ArticleOpen accessIn the abstractTransgenic Indian Cotton (Gossypium hirsutum) Harboring Rice Chitinase Gene (Chi II) Confers Resistance to Two Fungal PathogensM. Ganesan, P. Bhanumathi, K. Ganesh Kumari et al.Problem statement: The present investigation described a simple and reproducible protocol for transgenic cotton regeneration and characterization of chitinase (Chi II) gene expression against two different fungal pathogens in cotton. Approach: Transgenic cotton (Gossypium hirsutum cv. SVPR2) plants were produced by pCambia-bar-Chi II (13.8 kb) under the control of the CaMV 35S promoter, harbored in the strain LBA 4404 Agrobacterium … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 8,536 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHeavy Metals and Anion Levels in Some Samples of Vegetable Grown Within the Vicinity of Challawa Industrial Area, Kano State, NigeriaJ. C. Akan, F. I.A. Abdulrahman, V. O. Ogugbuaja, J. T. AyodeleProblem section: Effluents from the surrounding industries such as tannery and textile are used by vegetable farmers for the irrigation of their crops. These effluents may contain some toxic metals which bioaccumulate along the food chain. Moreover the uptake of such toxic metals by crops is governed by their availability and concentration in the soil. Therefore such crops may accumulate … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 9,278 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHard Coal Fly Ash and Silica-Effect of Fine Particulate Matter Deposits on Brassica chinensisChristian Ulrichs, Uwe Schmidt, Tanja Mucha-Pelzer et al.Problem statement: One focus in recent atmospheric pollution research is on fine Particle Matter (PM), especially as result of increasing traffic and anthropogenic activity in urban areas. Here, the impact on animal and human health has been in the center of many studies. Despite the fact that PM depositions can affect plants on the long term, there are only few … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,650 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDoes Trichomes on the Plant Epidermic Surface Disturb Ants Locomotion?Danon Clemes Cardoso, Maykon Passos Cristiano, Lenise Cristina Moraes Vilela, Tiago de Arruda MartinsProblem Statement: Many morphological characteristics, both physical and chemical, are used in the defense against herbivores on plants. Trichomes are structures used by plants as physics defense and when associated with glands combine physics and chemistry defense. Many species of ants are herbivores and use leaves and seeds, others ants use Extra Floral Nectars as a food resource, and the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,354 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,496 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInduced Resistance in Mycorrhizal Tomato is correlated to Concentration of Jasmonic AcidRupam KapoorThe study shows that Arbuscular Mycorrhizal Fungi (AMF) are capable of imparting disease tolerance in tomato plants pre-infected with Fusarium Oxysporum f. sp. Lycopersici (FOL). Inoculation of tomato seedlings with Glomus Macrocarpum (GM) or Glomus Fasciculatum (GF), 20 days after infection with FOL reduced pathogen spread and disease severity by 75 and 78 %, respectively. The mycorrhizal plants showed increased … …OnLine Journal of Biological Sciences, Vol. 8, Issue 3 · 30 Sep 2008 · 14,219 accessesView PDF Cite
