Microarray analysis of gene expression patterns in immature ear, seedling, and embryo tissues from the maize inbred lines B73 and Mo17 identified numerous genes with variable expression. Some genes had detectable expression in only one of the two inbreds; most of these genes were detected in the genomic DNA of both inbreds, indicating that the expression differences are likely caused by differe...

twenty local and foreign maize (zea mays l.) hybrids in five different maturity groups were evaluated in mashhad, iran for two years (2007-2009). three planting dates (5th may, 20th may and 5th june) and hybrids were arranged in a randomized complete block design as split plot arrangements, with three replications. the planting dates were in main plots and hybrids in subplots. the results indic...

Allele-specific expression refers to the preferential expression of one of the two alleles in a diploid genome, which has been thought largely attributable to the associated cis-element variation and allele-specific epigenetic modification patterns. Allele-specific expression may contribute to the heterosis (or hybrid vigor) effect in hybrid plants that are produced from crosses of closely-rela...

The transcription factor ZmbHLH16, the maize ortholog of OsTIP2 (OsbHLH142), was isolated in the present study. Tissue expression analysis showed that ZmbHLH16 is preferentially expressed in male reproductive organs. Subcellular location analysis of ZmbHLH16 via rice protoplast indicated that it is located in the nucleus. Through nucleotide variation analysis, 36 polymorphic sites in ZmbHLH16, ...

ERITABLE variations in inbred strains of maize occur infrequently. All H the mutations BO far found either do not increase the amount of growth and productiveness or clearly reduce the plants in some degree (JONES 1924, 193a, 1944; SINGLETON 1943). Several changes have been noted recently and reported in a preliminary way (JONES 1944) which reduce the vigor of the inbred plants but which increa...

Much of the variation in forage dibut there have been few significant breeding efforts specifically dedicated to improving maize forage yield or quality by breeders in the gestibility can be ac...

Nitrogen rate and time of application are among the major abiotic factors limiting productivity maize. The research was, therefore, carried out to examine response two maize varieties (Omankwa Pioneer hybrid) four different times N : P K 15 fertilizer during growing season in Ghana. experiment was arranged a randomized complete block design with eight treatment combinations three replications. ...
