Temporal dynamics of protein and post-translational modification abundances in Populus leaf across a diurnal period

ABSTRACT: Populus spp. are dedicated woody biomass feedstocks for advanced biofuels and bioproducts. Proper growth and fitness of poplar as a sustainable feedstock depends on timely perception and response to environmental signals (e.g., light, temperature, water). Poplar leaves, like other C3 photosynthesis plants, have evolved oscillating or circadian rhythms that play important roles in synchronizing biological processes with external cues. To characterize this phenomenon at a molecular level, we employed bottom-up proteomics using high-resolution mass spectrometry and de novo-assisted database searching to identify abundance changes in proteins and post-translational modifications in poplar leaf tissue sampled across a 12/12-hour light/dark diurnal period.

Transcriptional profiling of UV-B response of Populus alba.

Project description:Microarray technology was used to assess transcriptome changes in poplar (Populus alba L.) under a realistic simulation of increased UV-B radiation. Plants were UV-Bbe (UV-B biologically effective radiation) supplemented with a dose of 6 kJ/m2/day for 12 hours per day and allowed to recover during the night. Poplar plants were UV-B treated using a refined controlled environment able to guarantee a realistic simulation of natural conditions, especially for light parameters such as presence of background UV-B radiation for control plants and balanced PAR/UV-A/UV-B ratio. A time course experiment was planned to look both at the rapid and delayed response of poplar to UVB; two time points after 3 h (T3h) and 30 h (6th hour of the third day of treatment, T30h) were considered. 4 independent biological replicates were analysed for each time point. Competitive hybridisations were carried out using the PICME 28K microarray. Keywords: Time course experiment, stress response

Project description:To obtain genes expression in different parts of 84k poplar stems, transcriptome sequencing was performed using Illumina Novaseq 6000 second-generation sequencing platform from Shanghai BIOZERON Co. Ltd (www.biozeron.com). Selecte three stem segments of plants REPEAT 1, 2 and 3 with good and similar growth to use: 2nd-3rd internodes (poplar stem top: PST1, PST2, PST3); 9th-10th internodes (poplar stem middle: PSM1, PSM2, PSM3); 14th-15th internodes (poplar stem bottom: PSB1, PSB2, PSB3). [Or the three repeating organisms are also called poplar A, B, C. From top to bottom, the three parts of the stem are also called stem 1, 2, 3.]

High resolution survey of drought, high salinity, heat and cold stress-induced transcriptome of bioenergy feedstock model plant western poplar (Populus trichocarpa) accession Nisqually-1

Project description:Abiotic stress is a major factor affecting the growth, development, yield and quality in plants including the important biomass yield such as in a bioenergy feedstock crops. In a first of its kind, RNA-seq based high resolution survey of abiotic stress-induced transcriptome of bioenergy feedstock model plant western poplar (Populus trichocarpa accesion Nisqually-1) was carried out by way of 81 libraries made from total RNA isolated from three tissues, mature vascular leaf, stem xylem and root sampled from plants subjected to untreated control and treated with four individual stress treatments cold, heat, drought and high salinity. For every tissue and treatment type including controls, three individual plants were used per treatment as biological replicates.

Project description:Populus×canescens inoculated with or without different ectomycorrhizal fungi, Paxillus involutus (MAJ) and Cenococcum geophilum Fr., were co-cultured in greeenhouse for 16 weeks, then exposed to different water conditions (well-watered, drought and re-watered) for 4 weeks. Poplar leaves and roots were harvest for RNA sequenceing.

Transcription profiling of poplar plants grown in different light and temperature cycles

Project description:Poplar (Populus trichocarpa, clone Nisqually-1) plants were grown in a Conviron PGR 15 growth chamber using precise control of temperature, light, and humidity. Diurnal (driven) conditions included 12L:12D light cycles and 25C/12C thermocycles in three different combinations. These were: photocycles (LDHH), 12 hrs. light (L)/12 hrs. dark (D) at a constant temperature (25C; HH); photo/thermocycles (LDHC): 12 hrs. light (L) /12 hrs. dark (D) with a high day temperature (25C) and a low night temperature (12C); and thermocycles (LLHC): continuous light (LL) with 12 hrs. high/12 hrs. low temperature (25C, day; 12C, night). Light intensity and relative humidity were 700 micromol m-2s-2 and 50%, respectively. Three-month-old poplar plants were entrained for at least one week under the respective condition prior to initiation of each experiment. Leaves and stems from individual poplar plants were collected every four hours for 48 hrs in driven (diurnal) conditions followed by a two day freerun spacer under continuous light/temperature followed by two additional days of sampling under the same continuous free run condition.

Identification of rust-induced genes in poplar using Populus 4.6K cDNA macroarray

Project description:cDNA macroarray expression profiling was carried out in poplar leaves upon infection with rust in order to identify genes expressed during tree defense response. For this purpose, we inoculated detached leaves of the interamerican hybrid poplar Populus trichocarpa x Populus deltoides 'Beaupré' grown in greenhouse either with spores of avirulent strain 93ID6 (incompatible interaction, I) or spores of virulent strain 98AG31 (compatible interaction, C) of the pathogenic rust fungus Melampsora larici-populina. Besides, we mock-inoculated 'Beaupré' leaves with water (control condition, T). Detached leaves were maintained in vitro in controled conditions to allow fungal infection and colonization of plant tissue. Leaves were sampled at 12, 24 and 48 hours post-inoculation (hpi) in a time-course experiment before (12 hpi) and after (24 and 48 hpi) that the fungus attempt to penetrate plant cells in mesophyll. Keywords: Plant tissue infection, Plant defense response, cDNA macroarray

Light/dark- and temperature-regulated transcriptional rhythms in adult Caenorhabditis elegans

Project description:Most organisms have an endogenous circadian clock that is synchronized to environmental signals such as light and temperature. Although circadian rhythms have been described in the nematode C. elegans at the behavioral level, these rhythms appear to be relatively non-robust. Moreover, in contrast to other animal models, no circadian transcriptional rhythms have been identified. Thus, whether this simple nematode contains a bona fide circadian clock remains an open question. We used microarray experiments to identify light- and temperature-regulated transcriptional rhythms in C. elegans, and show that subsets of these transcripts are regulated in a circadian manner. In addition, we find that light and temperature also globally drive the expression of many genes, indicating that C. elegans exhibits systemic responses to these stimuli. Populations of growth-synchronized wild-type C. elegans L1 larvae were entrained for 5 days until adulthood to 12:12 hr light/dark (LD) cycles (500-1000 lux) at a constant temperature of 18°C, or for 4 days to 12:12 hr temperature cycles (25:15°C - warm/cold or WC) in constant darkness. RNA was collected every 4 hrs during the last entrainment and the subsequent free-running days and analyzed via hybridization of Affymetrix GeneChips. L4 larvae were transferred to FUDR-containing plates to inhibit embryonic development.
