TranscriptomicsMicroarray analysis of vegetative phase change in maize
Vegetative phase change is the developmental transition from the juvenile phase to the adult phase during which a plant becomes competent for sexual reproduction. Gain of ability to flower is often accompanied by changes in patterns of differentiation in newly forming vegetative organs. In maize, ...

TranscriptomicsHeterosis(II, Low scan)
Heterosis is the phenomenon whereby the progeny of particular inbred lines have enhanced agronomic performance relative to both parents. Although several hypotheses have been proposed to explain this fundamental biological phenomenon, the responsible molecular mechanisms have not been determined. ...

TranscriptomicsGene Expression between two cell layers in maize shoot apical meristem
All above ground organs of higher plants are ultimately derived from shoot apical meristems (SAMs). The SAM exhibits distinctive structural organization, and monocot SAMs such as maize are comprised of two cell layers, a single cell layered tunica (L1) and a corpus (L2). Although recent research ha...

TranscriptomicsGlobal gene expression analysis in the shoot apical meristem of maize
All above ground organs of higher plants are ultimately derived from specialized organogenic structures called shoot apical meristems (SAMs). It is comprised of pluripotent stem cells, which divide to regenerate themselves as well as to provide cells to form other organs such as leaves and stems. To...

TranscriptomicsA global analysis of gene expression in histological layers of the shoot apical meristem of maize
All above ground organs of higher plants are ultimately derived from specialized organogenic structures termed shoot apical meristems (SAMs). The SAM exhibits distinctive structural organization, marked by cell layering. Maize SAMs are comprised of two cell layers, L1 (single cell layered tunica) a...

TranscriptomicsDirect calibration of PICKY-designed microarrays
Picky is an optimal microarray design software which designed the NSF Rice 45K Array. A series of microarray experiments using a one-chip version of this array were conducted to validate as well as to develop a calibration method for Picky designed microarrays. Synthesized samples with known content...

TranscriptomicsGlobal Transcriptome Profiles in the Nodes of Rice During Spatial and Temporal Development
The following study was conducted to better understand the genetics of the spatial and temporal development of rice, especially as this relates to the development of lignocellulosic tissues. To do so, an oligonucleotide array was designed and created by the Plant Sciences Institute at Iowa State Uni...

TranscriptomicsNatural antisense transcripts accumulate for over 70% of maize genes and exhibit genotypic-specific expression patterns
Natural Antisense Transcripts (NATs) can regulate gene expression by virtue of their ability to form double-stranded RNA duplexes. To investigate NATs in the maize transcriptome, cDNAs from seedling of two inbred lines (B73 and Mo17) were hybridized to an oligonucleotide microarray designed to valid...
