(Submitter supplied) Colored-leaf plants are increasingly popular and have been attracting more and more attentions. However, studies about the anthocyanin components and molecular mechanisms of anthocyanin biosynthesis in QHP and ZSY was still unclear. In present study, an integrated metabolite and transcriptome profiling analysis was performed to explore the anthocyanin compositions and the specific regulatory network of anthocyanin biosynthesis in purple leaves of QHP and ZSY. more...

(Submitter supplied) Although poplars are good candidates for the phytoremediation of cadmium (Cd)-polluted soils and sulfur is a key player in modulating Cd detoxification and accumulation in plants, the physiological and molecular mechanisms underlying sulfur-mediated Cd accumulation remain largely unknown. To investigate physiological and transcriptomic regulation mechanisms of poplars in response to Cd exposure and different sulphate (S) supply levels, Populus deltoides saplings were exposed to either 0 or 50 µM Cd together with one of low, moderate and high S levels. more...

(Submitter supplied) Small non-coding RNAs (sncRNAs) are generated from different genomic loci and have important roles in biological processes, such as cell proliferation and regulation of gene expression. Next-generation sequencing (NGS) has provided an unprecedented opportunity to discover and quantify diverse kinds of sncRNAs, such as tRFs (tRNA-derived small RNA fragments), phasiRNAs (phased, secondary, small interfering RNAs), piRNAs and plant specific 24-nt short interfering RNAs (siRNAs). more...

(Submitter supplied) Ecto- and endo-mycorrhizal colonization of Populus roots have a positive impact on the overall tree health and growth. A complete molecular understanding of these interactions will have important implications for increasing agricultural or forestry sustainability using plant:microbe-based strategies. These beneficial associations entail extensive morphological changes orchestrated by the genetic reprogramming in both organisms. more...

(Submitter supplied) Diseases of poplar caused by the fungal pathogen Sphaerulina musiva and related species are of growing concern, particular with the increasing interest in intensive popluliculture to meet increasing energy demands. S. musiva is able to cause infection on leaves, resulting in defoliation and canker formation on stems. To gain a greater understanding of the different responses of poplar species to infection with their natural Sphaerulina species, RNA-seq was conducted on leaves of Populus deltoides, P. more...

(Submitter supplied) We conducted micro-array analysis to quantify the global transcriptome variations in floral organs of a male and female tree allowing for identification of sex-linked transcripts. We used RNA samples from male floral buds in August and female floral buds in Spetemeber. Bud scale were removed. While the sampling time differed, the developmental stage of the floral organs was similar between the male and female.

(Submitter supplied) Laccaria bicolor transcript profiles of different tissues and mycorrhizal root tips from different host trees were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) Laccaria bicolor genome sequence version 1. One goal was to compare gene expression profiles from ectomycorrhizal root tips with different host plants.

(Submitter supplied) The majority of trees live in association with symbiotic fungi, which facilitate their access to soil nutrients. The ectomycorrhizal symbiosis represents a complex biological system involving multifaceted interactions between the two partners. The establishment of the symbiosis depends on various conditions (e.g. climate), but also on the genetic traits of the partners. To evaluate the impact of the genetic predisposition on the development and functioning of ectomycorrhizas, we compared the transcriptome of roots from Populus trichocarpa and Populus deltoides colonized with Laccaria bicolor.

(Submitter supplied) cDNA macroarray expression profiling was carried out in poplar roots in order to identify genes regulated in response to exposition to copper stress. For this purpose, plants of a Populus deltoides clone grown in a hydroponic system during four weeks were incubated in a nutrient solution (Hoagland's modiefied salt, ¼ strength) supplemented with copper (0 µM (control), 30 µM and 60 µM). Roots were sampled at 12 and 24 h after exposition in a time-course experiment.

(Submitter supplied) To identify candidate genes involved in maturation and flowering, we conducted microarray expression studies using two poplar genotypes (Populus trichocarpa x P. deltoides hybrids) represented in continuous age gradients of one to six years. We designed 70-mers for 228 poplar genes and microarray studies were carried out using the microplate-based 96-well BioGridArray platform (GeneXP Biosciences). Floral buds, vegetative buds and shoot tips were collected at different seasonal time points from juvenile and adult trees and from both basal and upper branches of mature trees.
