Project description:Purpose: The goals of this study was to obtain transcriptome data from five developmental stages of adventitious roots of Pyrus ussuriensis Maxim using transcriptome analysis (RNA-Seq) and qRT-PCR analysis. Mathods: The mRNA profiles of the adventitious root development of Pyrus ussuriensis on day 0, day 3, day 6, day 9, and day 12 were examined by deep sequencing, in triplicate, using Illumina HiSeq 2000. Ultra™ RNA LibraryPrep Kit for Illumina® (NEB, USA) following manufacturer’s recommendations and indexcodes were added to attribute sequences to each sample. qRT–PCR validation was performed using TaqMan and SYBR Green assays. Results: The transcriptome regulation analysis of the Pyrus ussuriensis adventitious root formation was performed on this study. And a total of 19,470 DEGs (Differentially Expressed Gene), which were mainly enriched in hormone synthesis and signaling pathways, energy metabolism, synthesis and metabolism of secondary products, were detected. the key regulatory genes of adventitious root formation were screened, mainly including the gene family WOX, LBD and SRS. Auxin, plays a key role in the induction and development of root primordium, its signal transduction pathway-related genes were up-regulated during the induction period of root primordium, and down-regulated during the development of root primordia. Carotenoids is the precursor substance of abscisic acid synthetize. And for the reasons that the genes of carotenoid synthesis and signal transduction pathway of abscisic acid were down-regulated during the period of stable development and the root primordium induction, and up-regulated during the period of root primordium development of adventitious root, it was supposed that abscisic acid was a control substance, that regulated the metabolic network of development of adventitious roots. Conclusions: Our results provide a comprehensive high-resolution characterization of gene expression profiles during the pear root transition process.A number of DEGs were detected from the root primordium to adventitious root growth stages, and these belonged to hormone metabolism pathways.These results provide a valuable resource for studies in other closely related species with similar agricultural and productive value. The differentially expressed genes dataset will also provide useful candidate genes for functional analysis of pear rooting.

Project description:For the RNA-seq experiments approximately 3 cm stem segments were excised from 2-week-old in vitro plants and subsequently transfer to 1/2 MS medium and harvested the basal ends of stem cuttings (0.5 cm) at different time points(0, 0.5, 1, 2, 6, 12, 24, 48 and 96 h). Samples were collected from two biological replicates (40 cuttings each).

Project description: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.

Project description:Our previous studies have shown that exogenous ethylene (ETH) may induce plant adventitious root development in cucumber. In this study, transcriptome technique was used to explore the key genes in ETH-induced rooting. The results revealed that ETH regulated 1415 diferentially expressed genes (DEGs) during rooting, among which 687 DEGs were up-regulated and 728 DEGs were down-regulated. According to Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis, the critical pathways involved in ETH-induced adventitious root development were selected for further study, including carbon metabolism [starch and sucrose metabolism, glycolysis / gluconeogenesis, citrate cycle (TCA cycle), oxidative phosphorylation, fatty acid biosynthesis and fatty acid degradation], secondary metabolite biosynthesis (phenylalanine metabolism and flavonoid biosynthesis) and plant hormone signal transduction. In carbon metabolism, ETH reduced t the expression of CsHK2, CsPK2 and CsCYP86A1, whereas enhanced the expression of CsBAM1 and CsBAM3. Moreover, ETH negatively regulated the transcript level of CsPAL and CsF3’M and positively mediated that of CsPAO in secondary metabolite biosynthesis pathway. Additionally, ETH could induce adventitious rooting by negatively regulating auxin and ETH signal transduction-related genes (CsLAX5, CsGH3.17, CsSUAR50 and CsERS) and positively regulating ABA and BR signaling transduction-related genes (CsPYL1, CsPYL5, CsPYL8, CsBAK1 and CsXTH3) . Furthermore, the results of real-time PCR about the mRNA levels of these genes were consistent with transcriptome results. Therefore, ETH may induce adventitious root development by regulating carbon metabolism-related genes, secondary metabolite biosynthesis-related genes and plant hormone signal transduction-related genes.

Project description: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. (2010) and included a normalized cDNA library from different time points after taking the cuttings from mother plant. Because physiological processes and molecular changes specifically involved in AR formation were considered as of major interest, rather than those associated with wound responses, a filtration approach was chosen to eliminate primarily wound-responsive genes. This study is mainly focused on changes in transcript abundances of genes related to specific metabolic pathways or cellular events including primary metabolism, membrane transport, cell division or signalling during various phases of AR formation.
