(Submitter supplied) As maize seedlings germinate into the soil, they encounter an environment teeming with insects seeking rich sources of nutrition. Maize presumably has developed a number of molecular mechanisms to ensure survival at the beginning of its life cycle. Bioassays indicated maize seedlings were more toxic to caterpillars than shoots from 3 or 4 leafed plants. Microarray technology was utilized to document the expression of a number of genes with potential defensive functions in seedling tissue. more...

(Submitter supplied) In the current study a microarray (46k, University of Arizona, USA) analysis of 21 European maize (Zea mays L.) parental inbred lines (14 dent and 7 flint) was applied. The aim was the identification of parental genes which expression levels are correlated to heterosis and/or hybrid performance for grain yield (GY) and grain dry matter content (GDMC) in the hybrid progeny (F1). Therefore gene expression profiles of differentially expressed genes of the parental inbred lines at the seedling stage were correlated with GY- and GDMC-field data of 98 flint x dent factorial crosses gained at six different locations in Germany. more...

(Submitter supplied) Stalk borers are major pests for some of the most important crops in the world, such as maize or rice. Plant defense mechanisms against these herbivores have been poorly investigated. The maize´s stalk responds to insect feeding activating defense genes including hormone biosynthetic-related or proteinase inhibitor transcripts. The most outstanding conclusion is that cells in the maize´s stalk undergo cell wall fortification after corn borer tunneling. more...

(Submitter supplied) Waterlogging stress (WS) in a dynamic environment seriously limits plant growth, development, and yield. The regulatory mechanism underlying WS conditions at an early stage in maize seedlings is largely unknown. In the present study, the primary root tips of B73 seedlings were sampled before (0 h) and after (2 h, 4 h, 6 h, 8 h, 10 h, and 12 h) WS and then subjected to transcriptome sequencing, resulting in the identification of differentially expressed protein-coding genes (DEpcGs) and long non-coding RNAs (DElncRs) in response to WS. more...

(Submitter supplied) Genome-wide gene expression atlas of maize inbred line B73. Maize inbred B73 was used for constructing the gene atlas. Plants were grown in Plano silt loam soil at the West Madison Agricultural Research Station, Verona, WI during Summer 2008. During field preparation, 200 kg/acre of Urea (46-0-0) was applied. One day after planting, herbicides including Callisto (142 g/acre), Dual II (710 ml/acre), and Simazine (227 g/acre) were applied. more...

(Submitter supplied) 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 study global gene expression in maize SAM and very young primordia (P0 and P1), RNA was extracted from both SAMs (SAMs per se plus P0 and P1) and above-ground portions of seedlings collected from 14-day old B73 seedlings. more...
