Punctodera chalcoensis Stone et al. is a cyst nematode parasitizing corn (Zea mays L.) and teosinte (Zea mexicana (Schrad.) Kuntz) in Mexico (7). This nematode damages corn severely in Tlaxcala and Puebla states of Mexico (7). Pathogenic studies of P. chalcoensis on corn have been conducted in the greenhouse (2). Mundo-Ocampo and Baldwin (6) reported that P. chalcoensis induces a syncytium in r...
Abstract—Selenium is an-antioxidant which is important for human health enters food chain through crops. In Kenya Zea mays is consumed by 96% of population hence is a cheap and convenient method to provide selenium to large number of population. Several soil factors are known to have antagonistic effects on selenium speciation hence the uptake by Zea mays. There are no studies in Kenya that has...
agrobacterium tumefaciens mediated transformation may offer a better alternative than the biolistic gun for genetic transformation of maize plants. this gene delivery system results in a greater proportion of stable, low-copy number transgenic events than does the biolistic gun, and is highly efficient. in the present work, we studied maize transformation using a. tumefaciens by identifying som...
A natural dye lawsone (2-hydroxy-1, 4-naphthoquinone) was isolated from dry leaves of Lawsonia inermis L., by extraction with clove oil, ethyl alcohol, water and its effectiveness as staining agent for angiospermic stem tissue was studied. Lawsonia revealed meta-chromatic property of staining. A 10%w/v crude extract of Lawsonia inermis L., leaves in ethyl alcohol and water were used for stainin...
