(Submitter supplied) The loss of rooting capability following the transition from the juvenile to the mature phase is a known phenomenon in woody plant development. Eucalyptus grandis was used here as a model system to study the differences in gene expression between juvenile and mature cuttings. RNA was prepared from the base of the two types of cuttings before root induction and hybridized to a DNA microarray of E. grandis. more...

(Submitter supplied) Rooting capability is one of the economically traits lost during the juvenile to mature phase change in woody plants. A comprehensive microarray analysis was performed to compare the profiles of gene expression in juvenile and mature cuttings from E. grandis, either auxin treated or untreated on days, 0, 1, 3, 6, 9 and 12 post excision. At the end of the experiment, root primordia were observed only in auxin treated juvenile cuttings. more...

(Submitter supplied) Background: The change from juvenile to mature phase in woody plants is often accompanied by a gradual loss of rooting ability, as well as by reduced microRNA (miR) 156 and increased miR172 expression. Results: We characterized the population of miRNAs of Eucalyptus grandis and compared by Northern blot the gradual reduction in miR156 and increase in miR172 expression during development to the loss of rooting ability. more...

(Submitter supplied) To reveal transcriptome dynamics during adventitious root formation in a coniferous tree, C. japonica, we conducted custom microarry experiments. Three parts from cuttings of easy-to-root clone of C. japonica were collected at eight time points during adventitious root formation. The results revealed major turning points on transcriptome toward adventitious root formation and the expression behavior of genes related to carbohydrate, plant hormone and others suggested the important biological changes for adventitious root formation.

(Submitter supplied) 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, juvenile leaves differ from adult leaves in morphology, anatomy, and cell wall composition. Whereas the normal sequence of juvenile followed by adult is repeated with every sexual generation, this sequence can be altered in maize by the isolation and culture of the shoot apex from an adult phase plant; an “adult” meristem so treated reverts to forming juvenile vegetative organs. more...

(Submitter supplied) The gene expression profiles of the differentiating xylem of 91 Eucalyptus grandis backcross individuals were characterized following a loop design (Churchill, G.A. Nat Genet. 2002 Dec;32 Suppl:490-5). In this design, RNA from genotype 1666 (labeled with Cy5) was hybridized with RNA from genotype 1667 (labeled with Cy3) on the first slide(GEO accession number GSM7637); the same genotype 1667 (now labeled with Cy5) was compared with genotype 1669 (Cy3) on the second slide (GSM7638), and so on. more...

(Submitter supplied) The cDNA microarray comprises 2608 ESTs, with four replicates. 555 ESTs represent the UniGene set derived from the sequencing of a cDNA library from Eucalyptus grandis differentiating xylem generated by the Forest Biotechnology Group at NCSU (egx prefix). The remaining 2053 ESTs are from four libraries from Eucalyptus grandis leaf and root tissue and two libraries from Eucalyptus tereticornis flower tissues, kindly made available by DuPont (Scott Tingey, DuPont Crop Genetics, Newark, DE). more...

(Submitter supplied) In order to identify genes specifically induced during various developmental stages of Adventitious Root (AR) formation (described in Ahkami et al. 2009) in leafy cuttings of Petunia hybrida (line W115) and to describe the series of physiological processes during adventitious rooting, a microarray-based transcriptome analysis in the stem base of the cuttings was conducted. The microarray was described by Breuillin et al. more...
