“…Confirmation of putative defense mechanisms using bioassays with artificial diets developed for EAB (Keena et al ., ) have been a useful contribution (Whitehill et al ., ), but further verification is still required. The development of genomic and transcriptomic resources would also contribute to increased understanding of resistance mechanisms (Parent et al ., ). Currently, only a few published studies have explored the constitutive transcriptome of ash (Bai et al ., ) and EAB (Mittapalli et al ., ; Rajarapu, ).…”

63I.64II.64III.65IV.71V.7275References75 Summary We review the literature on host resistance of ash to emerald ash borer (EAB, Agrilus planipennis), an invasive species that causes widespread mortality of ash. Manchurian ash (Fraxinus mandshurica), which coevolved with EAB, is more resistant than evolutionarily naïve North American and European congeners. Manchurian ash was less preferred for adult feeding and oviposition than susceptible hosts, more resistant to larval feeding, had higher constitutive concentrations of bark lignans, coumarins, proline, tyramine and defensive proteins, and was characterized by faster oxidation of phenolics. Consistent with EAB being a secondary colonizer of coevolved hosts, drought stress decreased the resistance of Manchurian ash, but had no effect on constitutive bark phenolics, suggesting that they do not contribute to increased susceptibility in response to drought stress. The induced resistance of North American species to EAB in response to the exogenous application of methyl jasmonate was associated with increased bark concentrations of verbascoside, lignin and/or trypsin inhibitors, which decreased larval survival and/or growth in bioassays. This finding suggests that these inherently susceptible species possess latent defenses that are not induced naturally by larval colonization, perhaps because they fail to recognize larval cues or respond quickly enough. Finally, we propose future research directions that would address some critical knowledge gaps.

Introduction: The high-throughput genomic and transcriptomic approach has been developed and implemented to address the main challenges that the timber forestry sector faces, such as population growth, climate change, deforestation and the loss of forest ecosystem services. Objective: To carry out a bibliographic review focused on the genomes and transcriptomes of timber trees reported in the databases, with special attention to red cedar (Cedrela odorata L.), due to its importance as precious wood in Mexico. Methodology: A literature review was carried out, directed at studying timber trees with genomic and transcriptomic strategies in different databases such as Pubmed, Scopus, Google Scholar, ScienceDirect, Wiley Online Library, MDPI and Scielo to identify the timber species that have been reported genomes and transcriptomes. The structure of the review was the genomics of timber trees, the transcriptomics of wood, and the potential species for study due to their importance and finally, the databases for consultation. Subsequently, a bibliometric study was carried out with the bibliometrix library in R Studio. Main results: The first genome to be assembled at the chromosome level was the black cottonwood. Among the timber trees, the genomes of black cottonwood, desert poplar, eucalyptus and oak with a length of 392, 496, 691 and 789 Mb have been reported. Through study of the transcriptome, it has been possible to identify genes related to formation of the wood in a hybrid poplar (Populus alba L. × P. glandulosa) and P. tremula L. and with drought tolerance in Pinus massoniana and Pinus pinaster Aiton. In red cedar (Cedrela odorata L.), the transcriptome was obtained by sequencing a single leaf, identifying 52,181 gene models. In the NCBI, EMBL-EBI, TreeGenes, PLAZA databases and the hardwood genomics website it is possible to find information related to the genomics and transcriptomics of timber species. Implications: More research is required in omics in timber, particularly in red cedar, since the search on these topics yielded little information. Conclusion: Through the bibliographic review in databases, the timber trees that have a described genome and transcriptome were identified. This information can be used for the assembly and annotation of new genomes, identification of genes and molecular markers, among other applications.
