Annexins have previously been identified and characterized in Arabidopsis and rice. They compose a multigene family in plants. In this study, we indicated the isolation and characterization of maize annexin genes across a whole genome using bioinformatics, microarray and real-time PCR methods. A total of 12 members of this family were identified in the maize genome. The 12 maize annexins were d...

Growth and development of fall armyworm, Spodoptera frugiperda (J. E. Smith), were compared in two laboratory trials between individuals oered transgenic maize seedlings, conventional maize seedlings, or artificial diet. Transgenic maize seedlings in the first and second trials expressed Cry9C (Event CBH 351) and Cry1A(b) (Event MON 810) Bacillus thuringiensis (Berliner) (Bt) endotoxin genes, r...

Geminivirus infectivity is thought to depend on interactions between the virus replication-associated proteins Rep or RepA and host retinoblastoma-related proteins (pRBR), which control cell-cycle progression. It was determined that the substitution of two amino acids in the Maize streak virus (MSV) RepA pRBR-interaction motif (LLCNE to LLCLK) abolished detectable RepA-pRBR interaction in yeast...

Genetically modified (GM) maize expressing the Bt-toxin Cry1Ab (Bt-maize) was tested for effects on survival, growth, and reproduction of the water flea Daphnia magna, a crustacean arthropod commonly used as a model organism in ecotoxicological studies. In three repeated experiments, D. magna were fed 100% ground maize in suspension, using either GM or isogenic unmodified (UM) maize. D. magna f...

In this paper,according to the characteristics of maize disease knowledge,OWL DL language was used to build maize diseases ontology, and the reasoning rule of maize diseases was defined by using the expressive ability of SWRL rule language.The author introduced several realizable reasoning functions,and achieved the diagnostic reasoning of maize disease knowledge by Jess inference engine.The re...

genetically modified (gm) foods hold the key to ending hunger and malnutrition in africa.   due to the increasing number of gmos cultivation and delay in the approval of biosafety law in nigeria, it has become necessary to screen maize products in order to determine the identity of the consumed daily foodstuffs. in this study, dna extraction from raw and processed maize foods sold commercially ...

A 2-yr field experiment was conducted to determine the effects on Diabrotica spp. (Coleoptera: Chrysomelidae) of an insecticidal seed treatment (Poncho 1250, (AI)/clothianidin) and a granular insecticide (Aztec 2.1G, (AI)/tebupirimphos and cyfluthrin) alone and in combination with maize producing the insectidical toxin Cry3Bb1 derived from the bacterium Bacillus thuringiensis (Bt). Yields for B...

Possible non-target effect of transgenic cry1Ie maize exerts on natural enemy community biodiversity in the field is unresolved. In the present study, a 2-yr comparison of transgenic cry1Ie maize (Event IE09S034, Bt maize) and its near isoline (Zong 31, non-Bt maize) on natural enemy community biodiversity were compared with whole plant inspections, pitfall traps and suction sampler. Natural en...
