Identification of genes involved in cell wall biogenesis in grasses by differential gene expression profiling of elongating and non-elongating maize internodes
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 a detailed transcriptome analysis that allowed the identification of genes involved in grass cell wall biogenesis is provided. Differential gene expression profiling, using maize oligonucleotide arrays, was used to id...
متن کاملComparative Spatial Variability in Faunal Composition Along Two Middle Devonian Paleoenvironmental Gradients
Previous studies of spatial patterns among fossil assemblages have demonstrated the utility of gradient analysis as a n investigative tool inpaleobiology. However, because lateral samples in these studies have routinely been widely spaced (commonly tens of kilometers apart), there is little sense of the degree to which faunas vary locally, relative to variation observed a t larger scales along ...
متن کاملRapid wall relaxation in elongating tissues.
Reported differences in the relaxation of cell walls in enlarging stem tissues of soybean (Glycine max [L.] Merr.) and pea (Pisum sativum L.) cause measurements of the yield threshold turgor, an important growth parameter, to be in doubt. Using the pressure probe and guillotine psychrometer, we investigated wall relaxation in these species by excising the elongating tissue in air to remove the ...
متن کاملTranscriptional Profiles Uncover Aspergillus flavus-Induced Resistance in Maize Kernels
Aflatoxin contamination caused by the opportunistic pathogen A. flavus is a major concern in maize production prior to harvest and through storage. Previous studies have highlighted the constitutive production of proteins involved in maize kernel resistance against A. flavus' infection. However, little is known about induced resistance nor about defense gene expression and regulation in kernels...
متن کاملCell wall development in maize coleoptiles.
The physical bases for enhancement of growth rates induced by auxin involve changes in cell wall structure. Changes in the chemical composition of the primary walls during maize (Zea mays L. cv WF9 x Bear 38) coleoptile development were examined to provide a framework to study the nature of auxin action. This report documents that the primary walls of maize cells vary markedly depending on deve...
