Male and female poplar leaves phosphoproteome

ABSTRACT: Nitrogen is a key factor impacting plant physiological processes and protein abundance. Although many proteins were changed substantially in poplar under N deficiency, the post-translational modifications in male and female poplars are still unclear. Therefore, we selected male and female poplars and analysed the changes of protein phosphorylation in response to N-deficient conditions.

Phosphoproteomic and Metabolomic Analyses Reveal Sexually Differential Regulatory Mechanisms in Poplar to Nitrogen Deficiency.

Journal of proteome research 20200204 3

Nitrogen (N) is a key factor impacting physiological processes in plants. Many proteins have been investigated in male and female poplars under N limitation. However, little is known about sex differences in the protein modifications and metabolites that occur in poplar leaves in response to N deficiency. In this study, as compared to N-deficient males, N-deficient females suffered greater damage from N deficiency, including chloroplast disorganization and lipid peroxidation of cellular membrane ...[more]

High productivity in hybrid-poplar trees without isoprene emission to the atmosphere

Project description:The use of hybrid-poplar tree plantations as a source for biofuels and biomass production in temperate regions of the Northern Hemisphere has also, unintentionally, increased forest isoprene emissions to the atmosphere. The consequences of increased isoprene emissions include higher rates of tropospheric ozone production and increases in atmospheric aerosol production. Using RNA interference (RNAi) to suppress isoprene emission in several gene insertion events of hybrid-poplars, we show that this trait, which has been assumed as a requisite for the tolerance of abiotic stress, is not required for high rates of woody biomass production, even in extremely hot and dry climates. Biomass production over four years in experimental poplar plantations in Arizona and Oregon was similar among genetic lines that emitted or did not emit significant amounts of isoprene. Lines that had substantially reduced isoprene emission rates also showed decreases in flavonol pigments, which reduce oxidative damage during extremes of abiotic stress; a pattern that would be expected to amplify metabolic dysfunction during abiotic stress. Compensatory increases in the expression of other proteomic components, however, such as those that disable superoxide and other free radicals, and the fact that most biomass is produced during the spring, prior to the hottest and driest part of the growing season, explains the apparent paradox of high biomass production with low isoprene emission. The results of this study provide optimism for designing agroforest plantations of the future that provide high rates of lignocellulose production while eliminating detrimental effects of isoprene emission on atmospheric quality.

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.

Poplar tissue types 1

Project description:Global gene expression pattern of different poplar tissue types were determined using a Nimblegen microarray based on JGI v1.1 gene models. All tissue except reproductive tissue were obtained from the same clone used for the poplar genome sequencing project (Populus trichocarpa Nisqually-1). Reproductive tissue were from wild Populus trichocarpa trees.

Poplar cultivars Soligo and Carpacio

Project description:affy_genomic_poplar - affy_genomic_poplar - The project aims to identify genes of interest for water deficit acclimation in poplar. We look for genes and gene expression networks related to drought stress in two hybrid cultivars, differing in their drought tolerance in field. Affymetrix poplar genome array was designed on several Populus species. In order to deal with comparative approaches, we checked the convenience of the array by hybridizing genomic DNA of the two hybrid cultivars (Populus deltoides × Populus nigra, namely ‘cv Carpaccio’ and ‘cv Soligo’). This point is important as transcript sequence might have diverged in the two genomes (Fossati et al, 2005), which could lead to absence of hybridization without physiological meaning. -Two poplar cultivars, Soligo (S) and Carpacio (C) were grown in controlled conditions. Mature leaves were collected and genomic DNA was extracted from leaves in CTAB buffer. gDNA was fragmented with DNAse1. DNA fragments were labelled with Biotin N6-ddATP and hybridized on Affymetrix poplar genome array. Two technical replicates per genotype were performed.

Watanabe2018_Simple markov model

Project description:Simple Markov model. There are 3 disease states: Healthy, Sick, and Dead, where the Dead state is terminal. The yearly transition probabilities are: Healthy to Dead: 0.01; Healthy to Sick: 0.2 for Male and 0.1 for Female; Sick to Healthy: 0.1; Sick to Dead: 0.3. The transition probability now depends on the cohort (Male or Female) and can be expressed as a function of a Boolean covariate Male. Initial conditions: Healthy = (50 Male, 50 Female), Sick = (0,0) and Dead = (0,0). Output: Number of men and women in each disease state for years 1-10.
