Project description:Eucalyptus urophylla is a commercially important wood crop plantation species due to its rapid growth, biomass yield, and use as bioenergy feedstock. We characterized the genetic diversity and population structure of 332 E. urophylla individuals from 19 geographically defined E. urophylla populations with a reliability of 14,468 single nucleotide polymorphisms (SNPs). We compared the patterns of genetic variation among these 19 populations. High levels of genetic diversity were observed throughout the 19 E. urophylla populations based on genome-wide SNP data (HE=0.2677 to 0.3487). Analysis with STRUCTURE software, Principal component analysis (PCA) and a neighbor-joining (NJ) tree indicated that E. urophylla populations could be divided into three groups, and moderate and weak population structure was observed with pairwise genetic differentiation (FST) values ranging from −0.09 to 0.074. The low genetic diversity and shallow genetic differentiation found within the 19 populations may be a consequence of their pollination system and seed dispersal mechanism. In addition, 55 core germplasms of E. urophylla were constructed according to the genetic marker data. The genome-wide SNPs we identified will provide a valuable resource for further genetic improvement and effective use of the germplasm resources.

Project description:In order to study the effect of polyploidization on gene expression in the leaves of Eucalyptus urophylla, triploid obtained by sexual polyploidization and its diploid control were used as materials, and leaves at different growth stages of different ploidies were collected for transcriptome sequencing.

Project description:We present a label free proteome dataset of the vascular sap proteome of three commercially important Eucalyptus species (Eucalyptus camaldulensis, Eucalyptus grandis and Eucalyptus urophylla). Protein extraction from the vascular system was carried out using a pressure bomb, in solution digested and peptides were analyzed using a Q-Exactive instrument. Protein identification was carried out using stringent database searches and only in silico predicted extracellular proteins were considered as part of the sap proteome. The results here described can be used as a reference for the proteome sap analysis of Eucalyptus plants grown under different conditions.

Project description:The daily cycle of night and day affects the behaviour and physiology of almost all living things. At the molecular level, many genes show daily changes in expression levels. To determine whether changes in transcript abundance occur in wood forming tissues of Eucalyptus trees we used a cDNA microarray to examine gene expression levels at roughly four hour intervals throughout the day. Experiments were performed using RNA extracted from two biological replicates - GU (Eucalyptus grandis x E. urophylla) and GC (Eucalyptus grandis x camaldulensis) trees. A loop design was used, linking six time points. A dye swap was incorporated to eliminate dye bias.

Project description:The intense human activities can cause irreversible environmental problems. Eucalyptus is a forest species widely used in planted forests, with a great capacity to assist in the mitigation of CO2 emissions and accumulation due to its C3 metabolism and high retention of carbon molecules in its biomass. The objective of this study was to investigate the differences in the sap proteome of two Eucalyptus species grown in an atmosphere enriched with CO2. For this purpose, young Eucalyptus grandis and Eucalyptus urophylla plants were grown in growth chambers 20 days under controlled atmospheric CO2 rates. The vascular proteome revealed 146 extracellular proteins, and their relative abundance was associated with the enriched atmosphere treatments. The analysis of protein function and abundance revealed that E. grandis proteins are mainly involved in organic substance metabolism and proteolysis, while less abundant proteins are related to cellular defense responses. Similar results were obtained for E. urophylla, with the most abundant proteins performing metabolic functions, while the least abundant protein was related to oxidative stress. These results may contribute to a better understanding of the mechanisms involved in the response of eucalyptus species to increased CO2 and provide useful information for the management and cultivation of these species in high levels of carbon dioxide environments.
