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: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.

The overall design of the custom microarray used in this study is described in Breuillin et al. (2010). In brief, a database of 24,816 unigene sequences (including 4,700 ESTs from P. hybrida cutting base and all public available P. hybrida and P. axillaris sequences) was used for construction of a custom microarray.

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: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. In juvenile cuttings, 363 transcripts were specifically upregulated, enriched in enzymes of oxidation/reduction processes. In contrast, in mature cuttings, 245 transcripts were specifically upregulated, enriched in transcription factors involved in the regulation of secondary metabolites. A gene encoding for nitrate reductase (NIA), an enzyme that is known to be involved in nitric oxide (NO) production, was among the genes that were upregulated in juvenile cuttings. Concomitantly, a transient burst of NO upon excision was higher in juvenile cuttings than in mature ones. Treatment with a NO donor improved rooting of both juvenile and mature cuttings. A single NIA gene was found in the newly released E. grandis genome sequence, the cDNA of which was isolated, overexpressed in Arabidopsis plants and shown to increase NO production. Therefore, higher levels of NIA in E. grandis juvenile cuttings might lead to their better ability to produce NO and form adventitious roots. The Arabidopsis transgenic plants did not exhibit significantly increased lateral or adventitious roots, suggesting that spatial and temporal rather than a constitutive increase in NO is favorable for root formation.

Project description:Cell totipotency and pluripotency are the cellular basis for root regeneration in Platycladus orientalis cuttings, and the regeneration of adventitious roots is a key determinant for improving stem-cutting. However, the cellular basis and physiological regulation of adventitious root formation are still ambiguous. In this work, root primordia initiation and organogenesis were histologically observed, dynamic alterations in soluble proteins were monitored, and Tandem Mass Tag protein profiling during adventitious root development was carried out.

The Arabidopsis transgenic plants did not exhibit significantly increased lateral or adventitious roots, suggesting that spatial and temporal rather than a constitutive increase in NO is favorable for root formation. E. grandis seedlings were grown from seeds to the age of 6-7 months. The seedlings were pruned either at 10-15 cm or at 150-200 cm above the ground. The newly developed shoots were used as cuttings. To induce rooting, auxin (6000 ppm of K-IBA), was applied by quick dipping (20 sec). Stem cuttings taken from low-pruned seedlings were found to be easy-to root, exhibiting 45% rooting after 14 days and 60% after 35 days. These cuttings were defined as juvenile (RNA from two biological replicates was extracted). In contrast, stem cuttings taken from high pruned seedlings, barely rooted (5%) after 35 days, and were defined as mature (RNA from two biological replicates was extracted). The two biological replicates was used to dye swap experimental design.
