(Submitter supplied) Despite the economic importance of grasses as food, feed and energy crops, little is known about the genes that control their cell wall synthesis, assembly and remodelling. Here we provide a detailed transcriptome analysis that allowed the identification of genes involved in grass cell wall biogenesis. Differential gene-expression profiling, using maize oligonucleotide arrays, was used to identify genes differentially expressed between an elongating internode, containing cells exhibiting primary cell wall synthesis, and an internode that had just ceased elongation and in which many cells were depositing secondary cell wall material. more...

(Submitter supplied) affy_ccr_maize - affy_ccr_maize - Cinnamoyl-CoA reductase (CCR) catalyzes a key step in monolignol biosynthesis. We show that downregulation of CCR in maize was associated with lower lignin content and a strong decrease in H units. Concomitantly, these cell wall modifications were associated with higher digestibility. On another hand, immunocytochemistry indicated a modification of lignification pattern and cellulose content. more...

(Submitter supplied) Cotton fiber ESTs were generated from 7-10 dpa fibers from the diploid species, Gossypium arboreum L. cv. AKA8401, at the Cotton Functional Genomic Center (CFGC) at the University of California-Davis (UCD) (cfgc.ucdavis.edu). A Unigene (UG)/Non-redundant (NR) set of 13,947 quality-controlled consensus sequences that define the cotton fiber transcriptome during rapid fiber elongation was assembled by Arpat et al 2004. more...

(Submitter supplied) Aerenchyma is a specialized tissue consisting of longitudinal gas spaces, which enables internal movement of gases (e.g., O2, CO2, ethylene and methane), in plant roots, petioles and stems. Especially, internal transport of oxygen via aerenchyma from shoots to roots is very important for adaptation or survival of plants under waterlogged condition. To identify aerenchyma formation-associated genes expressed in maize root, we used LM combined with a microarray for monitoring genes expressed in root cortical cells under three conditions: under aerobic condition and under waterlogged condition with and without pretreatment with 1-MCP, an inhibitor of ethylene perception.

(Submitter supplied) Drought is a major abiotic stress that threatens global food security. Circular RNAs (circRNAs) are endogenous RNAs. How these molecules influence plant stress responses remains elusive. Here, a large scale circRNA profiling identified 2174 and 1354 high-confidence circRNAs in maize and Arabidopsis, respectively, and most were differentially expressed in response to drought. A substantial number of drought-associated circRNA hosting genes were involved in conserved or species-specific pathways in drought responses. more...

(Submitter supplied) Dicer enzymes function at the core of RNA silencing to defend against exogenous RNA, or as an endogenous mechanism of gene regulation. Plant DICER-LIKE4 (DCL4) performs dual functions, acting in antiviral defense, as well as in development via the biogenesis of tasiR-ARFs. These small RNAs play an essential role in the grasses and act to spatially define the expression domain of AUXIN RESPONSE FACTOR3 (ARF3) transcription factors. more...

(Submitter supplied) The goal of the experiment was to perform a large scale study of circadian regulation of gene expression in maize. To identify maize genes with expression regulated by the circadian clock, transcript levels in the aerial tissues of young maize seedlings were determined by transcriptional profiling with the Affymetrix GeneChip Maize Genome Array. Maize inbred B73 seedlings were grown inside Conviron growth chamber. more...

(Submitter supplied) Periods of soil water deficit could occur at any time during the crop season, but maize is particularly sensitive to water stress around flowering time. At this time the stress usually causes remarkable yield loss. Heading time, which is just before tassel flowering, is one of the most important stages that maize productivity would be affected severely if plants encounter water stress. The whole-genomic gene expression changes of maize plants in response to water deficit stress at this stage have not been studied. more...

(Submitter supplied) The present study profiled and analyzed gene expression of the maize ear at four key developmental stages. Based on genome-wide profile analysis, we detected differential mRNA of maize genes. Some of the differentially expressed genes (DEGs) were predicted to be potential candidates of maize ear development. Several well-known genes were found with reported mutants analyses, such as, compact plant2 (ct2), zea AGAMOUS homolog1 (zag1), bearded ear (bde), and silky1 (si1). more...
