Project description:Iron (Fe) is an essential micronutrient for the survival and proliferation of plants. Plants have evolved complex mechanisms to maintain Fe homeostasis in response of Fe deficiency conditions. To explore the mechanisms of Populus tomentosa response to Fe deficiency, we evaluated the physiological, biochemical and transcriptome differences of P. tomentosa between Fe-sufficient and Fe-deficient conditions. The results showed that, under Fe-free conditions, the chlorophyll synthesis and photosynthesis pathways in shoots were extremely depressed. The inhibition of these pathways caused chlorosis and reduced shoot growth. Meanwhile, although both two photosynthetic systems (PSI and PSII) were inhibited under Fe limited conditions, PSI is affected more serious and earlier than PSII. In order to maintain Fe homeostasis, several genes involved in Fe regulation network were differentially expressed. At the late period of Fe deficiency response, some genes (BTS, bHLH38/39 and PYE) in PYE regulatory network were up-regulated in roots, while some root-specific ethylene-dependent FIT regulatory genes (EIN3, ERF and FIT) were down-regulated. Moreover, FRO2 was induced in P. tomentosa roots to reduce more Fe3+, which is similar with other strategy I plants. It is interest that we found another Fe2+ transporter gene (NRAMP1) was induced, instead of the well-known Fe2+ transporter gene (IRT1) for strategy I plants, to promote Fe2+ absorption at the Fe deficiency late stage.

Project description:Illumina GAIIx technology was used to generate mRNA profiles from the ectomycorrhizal fungi Laccaria bicolor colonizing roots of Populus trichocarpa. Samples were taken after two, four and 12 weeks of contact in order to identify mycorrhiza-regulated transcripts. 37bp reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) and the Laccaria bicolor (http://genome.jgi-psf.org/Lacbi2/Lacbi2.home.html) reference genomes using CLC Genomics Workbench 6.

Project description:Poplar GeneChip was employed to detect genes expressed during the whole floral developmental process, in order to improve understanding of poplar flower development, since current knowledge on flower development was mainly from model plant Arabidopsis. Male and female floral buds of Populus tomentosa were selected at successive stages of the whole development process for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain genes contributed to floral development, but not the dynamic expression changes. To that end, equal amount of floral buds RNA per gender from different stages were mixed for the detection of expressed genes.

Project description:Just as animal monozygotic twins can experience different environmental conditions by being reared apart, individual genetically-identical trees of the genus Populus can also be exposed to contrasting environmental conditions by being grown in different locations. As such, clonally-propagated Populus trees provide an opportunity to interrogate the impact of individual environmental history on current response to environmental stimuli. To test the hypothesis that current responses to an environmental stimulus, drought, are contingent on environmental history, the transcriptome-level drought responses of three economically important hybrid genotypes: DN34 (Populus deltoides x P. nigra); Walker (P. deltoides var. occidentalis x (P. laurifolia x P. nigra)); and, Okanese (‘Walker’ x (P. laurifolia x P. nigra)) derived from two different locations were compared. Strikingly, differences in transcript abundance patterns in response to drought were based on differences in geographic origin of clones for two of the three genotypes. This observation was most pronounced for the genotypes with the longest time since establishment and last common propagation. Differences in genome-wide DNA methylation paralleled the transcriptome level trends, where the clones with the most divergent transcriptomes and clone history had the most marked differences in the extent of total DNA methylation, suggesting an epigenetic basis for the clone-history-dependent transcriptome divergence. The data provide insights into the interplay between genotype and environment in the ecologically and economically important Populus genus, with implications for both the industrial application of Populus trees, and the evolution and persistence of these important tree species.
