Proteomics reveals proteins linked to the quality of wood in contrasting xylem of Eucalyptus clones
نویسندگان
چکیده
Background Eucalyptus spp. is a genus widely planted in many tropical and subtropical regions of the world as a major source in the production of pulp and paper. Aiming to meet the demand required by the world market papermaker, with the need for greater productivity in forests, as well as higher quality of wood, reducing the amount of lignin and extractive, is that proteomics emerges as an additional tool to help accelerate progress in the selection of elite clones.

Eucalyptus transcriptome analysis revealed molecular chaperones highly expressed in xylem
Background Plant development is very plastic, being coupled to environmental cues. As sessile organisms, plants must be able to respond rapidly to environmental stresses such as changes in temperature and salinity, heavy metals and water deficit. Efficient stress response systems are prerequisites for plant survival and productivity [1]. Molecular chaperones (or Heat Shock Proteins – HSP) compo...
متن کاملProteomics of Plasma Membranes from Poplar Trees Reveals Tissue Distribution of Transporters, Receptors, and Proteins in Cell Wall Formation*
By exploiting the abundant tissues available from Populus trees, 3-4 m high, we have been able to isolate plasma membranes of high purity from leaves, xylem, and cambium/phloem at a time (4 weeks after bud break) when photosynthesis in the leaves and wood formation in the xylem should have reached a steady state. More than 40% of the 956 proteins identified were found in the plasma membranes of...
متن کاملGenetic control of Eucalyptus urophylla and E. grandis resistance to canker caused by Chrysoporthe cubensis
Chrysophorte cubensis induced canker occurs in nearly all tropical and subtropical regions where eucalypts are planted, causing losses in both wood quality and volume productivity, especially so in the warmer and more humid regions of Brazil. The wide inter and intra-specific genetic variability of resistance to canker among Eucalyptus species facilitates the selection of resistant plants. In t...
متن کاملComparative transcriptome analysis of tree Eucalyptus species using RNAseq technology: analysis of genes interfering in wood quality aspects
Background The Eucalyptus wood is one of the most important raw materials for pulp and paper industry. Brazil is currently the first producer of short-fiber pulp and sixth in total production of cellulose. To maintain the industrial competitiveness, investment in genomic research started in 2002 with the GENOLYPTUS project (Brazilian Network of Eucalyptus Genome Research). Recently, a new trans...
متن کاملVariability in wood properties of promising willow clones
The objective of the article is to investigate the variability in growth and wood properties of the willow clones. The growth and wood traits of four year old 21 clones willow clones were investigated. Analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. Among the growth parameters the maximum heritability value was shown by height wh...
