Populus tissue analysis

ABSTRACT: We analyzed the transcriptome in roots, young and mature leaves, nodes and internodes in the reference genotype Nisqually-1 and identified a core set of approximately 10,000 genes expressed in common among vegetative organs. Quantitative contrasts of transcript levels among organs identified expected patterns of expression associated with organ-specific physiological processes, although a surprisingly high number of defense-related genes were preferentially expressed in young leaves and nodes. Application of a novel runs test established an objective criterion for the identification of genomic regions in which adjacent genes were expressed more frequently than expected by chance, suggesting the presence of chromatin domains. Comparisons between P. trichocarpa Nisqually-1 and the P. tremula X P. alba hybrid INRA 717-1B4 revealed similar expression patterns, particularly in stems. Although a comparison to Arabidopsis thaliana revealed similar proportions of expressed genes in leaves and stems, there was very little conservation between rank correlations of expression patterns. Keywords: gene expression

Transcriptomic and proteomic analyses of distinct Arabidopsis organs reveal high PSI-NDH complex accumulation in stems

Project description:In addition to leaves, the main site of photosynthetic reactions, active photosynthesis also takes place in stems, siliques and tree trunks. Although non-foliar photosynthesis has a marked effect on plant growth and yield, only limited information on the expression patterns of photosynthesis-related genes and the structure of photosynthetic machinery in different plant organs has been available. Here, we report the results of transcriptomic analysis of various organs of Arabidopsis thaliana and compare the gene expression profiles of young and mature leaves with a special focus on photosynthetic genes. Further, we analyzed the composition and organization of the photosynthetic electron transfer machinery in leaves, stems and green siliques at the protein level using BN-PAGE. RNA-Seq analysis revealed unique gene expression profiles in different plant organs and showed major differences in the expression of photosynthesis-related genes in young as compared to mature rosettes. Gel-based proteomic analysis of the thylakoid protein complex organization further showed that all studied plant organs contain the necessary components of the photosynthetic electron transfer chain. Intriguingly, stems accumulate high amounts of PSI-NDH complex, which has previously been implicated in cyclic electron transfer.

Effect of MiSSP7 overexpression on the Poplar root transcriptome

Project description:The Poplar transcriptome was analyzed in Populus tremulaxPopulus alba clone 717-1B4 control roots and in two poplar lines overexpressing MiSSP7. We performed 9 hybridizations (NimbleGen) with samples derived from Populus tremulaxPopulus alba clone 717-1B4 control roots, as well as from roots of LINE1 and LINE2 MiSSP7 overexpressor poplars (3 biological replicates each). All samples were labeled with Cy3.

Cell wall proteome of sugarcane young and mature leaves and stems

Project description:By characterizing the cell wall proteomes of different sugarcane organs (leaves and stems) at two developmental stages (young vs mature/apical vs basal), it was possible to address unique characteristics in each of them. Four-month-old leaves showed a higher proportion of oxido-reductases and proteins related to lipid metabolism (LM), besides a lower proportion of proteins acting on polysaccharides, in comparison to four-month-old internodes. It was possible to note that sugarcane leaves and young stems have the highest LM rate than all species, which was assumed to be linked to cuticle formation. The data generated enriched the number of cell wall proteins (CWPs) identified in sugarcane, reaching 277. To our knowledge, sugarcane has now the second higher coverage of monocot CWP in plants

RNA-seq analysis of rice leaves, nodes and stems

Project description:To explore the molecular mechanism of callus formation in nodes, we performed an RNA-seq experiment, using a mixture of nodes I and II compared to stems and mature leaves. We identified 1,741 candidate genes that were preferentially expressed in the node.

Regulation of gene expression by Candidatus Liberibacter asiaticus in stem and root of Sweet orange (Citrus Sinensis)

Project description:Candidatus Liberibacter asiaticus infection of citrus is characterized by symptom variability within and among organs. In order to identify molecular processes involved in the regulation of organ response to Ca. Liberibacter infection, the gene expression patterns in C. sinensis leaf, stem, and root was examined in Affymetrix microarray. Our analyses showed that Ca. L. asiaticus reprograms several cellular and metabolic processes in C. sinensis, with most categories regulated in leaves, followed by stems and least in roots. Among them, we identified genes whose expression is regulated in organ-specific manner, reflecting organ specialization in the molecular response to Ca. L. asiaticus. Differences in gene expression were expected between these organs because of functional divergence among them.

Effect of Methyl jasmonate of the Poplar root transcriptome

Project description:Illumina HiSeq technology was used to generate mRNA profiles from Populus tremula x alba INRA 717-1B4 roots treated with Methyl jasmonate. Samples were harvested after two weeks either from untreated control roots or from Methyl jasmonate treated roots. Paired-end (2X100bp) reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) using CLC Genomics Workbench 6. mRNA profiles from Populus tremula x alba INRA 717-1B4 roots treated with Methyl jasmonate as well as from control roots were generated by paired-end (2X100bp) Illumina HiSeq sequencing. Four samples were sequenced per lane, two biological replicates per treatment.

Expression data from leaves of GA-deficient and GA-insensitive transgenic poplar

Project description:We used whole-genome microarrays to identify differentially expressed genes in leaves of GA-deficient (35S::PcGA2ox) and/or GA-insensitive (35S::rgl1) transgenics as compared to WT poplar (717-1B4 genotype). Our work suggests that the molecular machinery that reduces gibberellins (GAs) concentration and signaling is a major route for restraining growth under both immediate and imminent adverse conditions. We show that inhibition of growth as a result of water deprivation and short days (SDs) coincides with up-regulation of several DELLA and GA2ox encoding genes in poplar. Likewise, GA-deficient and GA-insensitive transgenics, with up-regulated GA2ox and DELLA domain proteins, elicited a hypersensitive growth inhibition in response to both drought and SDs. Because the GA-modified transgenic showed accelerated response to drought and SD, we hypothesized that the mechanisms associated with these responses are constitutively elevated even under control conditions (well-watered, long day photoperiod). Therefore, we used whole-genome poplar microarray to study transcriptome level changes in the leaves of transgenic compared to WT plants grown under control environment. Genetic background for all plants was INRA 717-1B clone (Populus tremula x Populus alba). Expression analysis was preformed on three individual genotypes; wild-type (WT, untransformed control), 35S::PcGA2ox and 35S::rgl1. Leaves from two independent biological replicates per genotype were used, each pooled from 20 clonally propagated plants.
