Overlap of differentially expressed genes of all genotype comparisons. 4). Compatible with any devices. Download List of Library Books and Periodicals book written by Montreal. The parental inbred line with the larger estimated expression level within a given gene was termed high parent (HP), whereas the other parent was labeled as low parent (LP). Plant physiology describes the physiology and functioning of the plants. Besides, the subject is closely connected to the fields such as plant morphology, phytochem… Overview of RNA-seq sample relationship. For all four tissues, the pairwise comparison between the two parental inbred lines B73 and Mo17 revealed the highest number of differentially expressed genes. We thank Hans-Peter Piepho (Institute for Crop Sciences, Biostatistics Unit, University of Hohenheim, Stuttgart, Germany) for advice in statistical questions. It also deals with the topics including seed germination, environmental stress physiology, stomata function and dormancy. Both the main- and subplot represent in a split plot design a randomization unit and need therefore be represented by a random error term each.

S1). nonadditive expression, widely varied between different species, tissues, and genotypes (Guo et al., 2006; Stupar and Springer, 2006; Swanson-Wagner et al., 2006; Uzarowska et al., 2007; Stupar et al., 2008; Hoecker et al., 2008b; Paschold et al., 2012). Anatomy& Physiology. 4; Supplemental Tables S1 and S2). Among the expressed genes with SNPs, only between 28% (3,596/12,963 in cortex) and 30% (3,809/12,903 in meristematic zone) were nonsyntenic. Hypothesis tests were performed using the contrasts.fit function of the Bioconductor package limma (Smyth, 2005). The comparison between cortex and stele, which are both complementary tissues of the differentiation zone and between the elongation and the meristematic zone, revealed the smallest numbers of differentially expressed genes (Fig. A, Color-coded schematic of the four mechanically separated maize primary root tissues: yellow, cortex (C); light green, stele (S); green, elongation zone (EZ); dark green, meristematic zone (MZ). Differentially expressed genes (DEGs) were identified on the basis of six pairwise comparisons between the four analyzed root tissues: cortex (C, yellow), stele (S, light green), elongation zone (EZ, green), and meristematic zone (MZ, dark green) among the four maize genotypes B73 (A), Mo17 (B), and their reciprocal hybrids B73xMo17 (C) and Mo17xB73 (D). In total, 1,056 and 824 nonadditively expressed genes were exclusively identified in the hybrids B73xMo17 and Mo17xB73, respectively. Whilst multi author texts can cause problems of lack of uniformity of approach, each contributor has been made aware of the contents of the other chapters in an attempt both to provide continuity and to prevent glaring overlaps.

In all inbred versus hybrid comparisons, a significantly higher number of differentially expressed genes was preferentially expressed in the hybrids. For subsequent analyses only uniquely mapping reads with a maximum of two mismatches out of 36 bp and with ideally 5 bp tails for every 76 bp were used. J.A.B., A.P., and F.H. Several genetic hypotheses have been proposed that make the combination of a remarkable number of genes responsible for heterosis. Fast Download Speed ~ Commercial & Ad Free. Fotos, Videos, Dokumente und mehr ganz einfach speichern und teilen - überall und auf jedem Gerät, und das kostenlos. or. 1A), based on a RNA-seq dataset from our laboratory (Paschold et al., 2014). Unexpected allelic expression patterns might be predetermined by the epigenetic status of the parental genomes and the activation of transposable elements or uniparental expression of noncoding RNAs (for review, see Groszmann et al., 2013). For all four possible parent-hybrid comparisons, in each tissue between 1,104 (B73 versus B73xMo17 in elongation zone) and 1,582 (Mo17 versus B73xMo17 in stele) differentially expressed genes were estimated by controlling the false discovery rate (FDR) at 5% and an absolute log2 fold change (FC) > 1 (Fig. Within each class, the overlap of the nonadditively expressed genes between the two hybrids was significantly higher than expected. The activation state of malate dehydrogenase, which reflects reduced thioredoxin and NADP/NADPH ratios, was found to … Supplemental Data File S1. Premium PDF Package . These genetic hypotheses attribute heterosis to the complementation of superior dominant alleles (dominance hypothesis), allelic interactions at one or multiple loci (overdominance hypothesis), or epistatic interactions between nonallelic genes (for review, see Birchler et al., 2006; Hochholdinger and Hoecker, 2007). The numbers in parentheses indicate the total number of genes with unexpected allelic ratio in the corresponding root tissue.

Gene lists for all analyzed expression patterns in the four tissues of the primary maize roots. We determined if the evolutionary origin of genes correlates with the intraspecific transcriptome diversity between parental inbred lines B73 and Mo17 and their reciprocal hybrids. In the meristematic zone, new root cells are formed by cell division and are dislocated proximally into the elongation zone, where they elongate. In comparison, 47% (78/166) of genes with unexpected allelic ratios were nonsyntenic in cortex, 41% (73/177) in the elongation zone, 58% (118/202) in the meristematic zone, and 39% (124/321) in the stele (Fig. 1C). Library, available in PDF, EPUB, and Kindle, or read full book online anywhere and anytime. In this study, we investigated how the genetic divergence of the maize inbred lines B73 and Mo17 and their F1 hybrid progeny is reflected in differential, nonadditive, and allelic expression patterns in primary root tissues. Advances in Plant Physiology Vol 17 . In a comparative genomic study in Arabidopsis (Arabidopsis thaliana), it was shown that disease resistance genes were significantly overrepresented among genes found in nonsyntenic regions (Freeling et al., 2008). While the reciprocal hybrids, which contain an identical nuclear genome, did not display any differentially expressed genes, the genetically distinct parents displayed a high degree of differential gene expression. SPE is an extreme instance of expression complementation in which genes are expressed in both reciprocal hybrids but only in one of the two parental inbred lines (Paschold et al., 2012). Guyton and Hall is a book for First Year MBBS Students and is the best and recommended book for Physiology. Easy! Using the allelic read counts, the hypothesis test that the ratio of the expression of the parental alleles in both inbred lines equals to the ratio of the expression of the parental alleles in a specific hybrid was performed by applying the contrasts.fit function in limma (Smyth, 2005). The number of genes in each expression class was estimated by combining three pairwise t tests that compared the expression level of the hybrid with each parent and between both parents (Supplemental Table S2). Get any books you like and read everywhere you want. In all four genotypes, the relative number of differentially expressed genes in the six comparisons was similar. Taiz & Zeiger- Plant Physiology. Plant Physiology by Taiz and Zeiger (2010) “Stress is a disadvantageous influence exerted on a plant by external abiotic or biotic factor(s), such as infection, or heat, water and anoxia. Advances in Plant Physiology Vol 15 . In the past 50 years, global maize production has increased almost 5-fold (http://faostat3.fao.org/). These observations underscore the role of these genes in shaping the transcriptomic landscape of the reciprocal maize hybrids B73xMo17 and Mo17xB73, which might be associated with the developmental manifestation of heterosis. A similar observation was made in the four maize primary root tissues, where nonsyntenic genes were significantly overrepresented among genes displaying SPE patterns (Paschold et al., 2014). conceived the research; J.A.B. Supplemental Table S2. Based on the synteny to sorghum, the genome of maize can be subdivided into two subgenomes, which contain pairs of duplicated genes shared by both subgenomes but also single-copy genes present in only one of the two subgenomes (Schnable et al., 2011). This Decision is addressed to Professor J. Geuns, KUL, Laboratory of Plant Physiology, Kardinaal Mercierlaan 92, 3001 Heverlee, Belgium. This result is consistent with the previous findings obtained in maize top ear shoots (Qin et al., 2013), in which approximately two-thirds of the differentially expressed genes were up-regulated in the F1 hybrid relative to the parental inbred lines. Intermediate numbers of differentially expressed genes were observed in comparisons of hybrids with one of the parental inbred lines. To identify overrepresented biological and molecular functions among the nonsyntenic genes with nonadditive and allelic expression patterns, a Gene Ontology (GO) analysis was performed. Hierarchical clustering and multidimensional scaling plots of all samples revealed high correlation of gene expression in the adjacent meristematic and elongation zones and only low correlation of these zones with cortex and stele tissue of the differentiation zone (Fig. The 64 cDNA libraries were loaded on two flow cells according to a split plot design (supplemental table S1 in Paschold et al., 2014). Seeds of many plant species are green during embryogenesis.

Similarly, mapping of Mo17 genomic sequences to the B73 reference genome revealed that only 63% of the sequences were identical in both genotypes (Wei and Wang, 2013). 5C; Supplemental Data File S1). No differentially expressed genes were detected between reciprocal hybrids, which share the same nuclear genome. our understanding of the factors affecting the growth and productivity of grasslands has trailed in the shadow of the determined efforts made to improve our knowledge of cereals and, to a somewhat lesser extent, legumes. READ PAPER. In addition, normally distributed random effects for main- and subplot were included. A previous study of our research group revealed dynamic root tissue-specific patterns of single-parent expression (SPE), an extreme instance of expression complementation in which genes are expressed in both reciprocal hybrids but only in one parental inbred line (Paschold et al., 2014).
