Poplar estradiol study-TRANSCRIPTOMIC ANALYSIS OF POPLAR STEM ACCOMMODATION TO REPEATED BENDING Species: Populus tremula x Populus aba

ABSTRACT: affy_pop_2011_08 - poplar estradiol study - genes regulated by PtaZFP2 in absence of mechanical stress - genes regulated by PtaZFP2 after one bending.Species: Populus tremula x Populus alba-The laboratory previously established a poplar transgenic line overexpressing PtaZFP2 under the control of an estradiol-inducible promoter. - the experiment, conducted on 3-month-old hydroponically-grown poplars, consists in the comparison of WT poplars treated with estradiol and the PtaZFP2-overexpressing line treated with estradiol. We also compared unbent and bent PtaZFP2-overexpressing poplars. The applied strain is quantitatively controlled (Coutand & Moulia, 2000, JExpBot; coutand et al., 2009, Plant Physiology) 9 arrays - poplar; time course

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.

Identification of rust-induced genes in poplar using Populus PICME 28K cDNA microarrays

Project description:Microarray 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 with spores of avirulent strain 93ID6 of the pathogenic rust fungus Melampsora larici-populina (incompatible interaction, I48). Besides, we mock-inoculated 'Beaupré' leaves with water (control condition, T48). Detached leaves were maintained in vitro in controled conditions to allow fungal infection and colonization of plant tissue. Leaves were sampled 48 hours post-inoculation after that the fungus attempt to penetrate plant cells in mesophyll. Competitive hybridization between transcripts of incompatible interaction (I48) and control condition (T48) was done on Populus PICME 28K cDNA microarray. Keywords: Time-course infection of plant tissue, defense response, cDNA microarray

Identification of rust-induced genes in poplar using Populus 2.0 NimbleGen oligoarray

Project description:Oligoarray 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 I48) or spores of virulent strain 98AG31 (compatible interaction C48) of the pathogenic rust fungus Melampsora larici-populina. Besides, we mock-inoculated 'Beaupré' leaves with water (control condition, T48). Detached leaves were maintained in vitro in controled conditions to allow fungal infection and colonization of plant tissue. Leaves were sampled 48 hours post-inoculation after that the fungus attempt to penetrate plant cells in mesophyll. Keywords: Plant tissue infection, Plant defense response, Oligonucleotide array

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.

male and female poplar leaves phosphoproteome

Project description: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.

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
