BackgroundProtium species produce abundant aromatic oleoresins composed mainly of different types of terpenes, which are highly sought after by the flavor and fragrance industry.ResultsHere we present (i) the first draft genome of an endemic tree of the Brazil’s Atlantic Rainforest (Mata Atlântica), Protium kleinii Cuatrec., (ii) a first characterization of its genes involved in the terpene pathways, and (iii) the composition of the resin’s volatile fraction. The de novo draft genome was assembled using Illumina paired-end-only data, totalizing 407 Mb in size present in 229,912 scaffolds. The N50 is 2.60 Kb and the longest scaffold is 52.26 Kb. Despite its fragmentation, we were able to infer 53,538 gene models of which 5,434 were complete. The draft genome of P. kleinii presents 76.67 % (62.01 % complete and 14.66 % partial) of plant-core BUSCO genes. InterProScan was able to assign at least one Gene Ontology annotation and one Pfam domain for 13,629 and 26,469 sequences, respectively. We were able to identify 116 enzymes involved in terpene biosynthesis, such as monoterpenes α-terpineol, 1,8-cineole, geraniol, (+)-neomenthol and (+)-(R)-limonene. Through the phylogenetic analysis of the Terpene Synthases gene family, three candidates of limonene synthase were identified. Chemical analysis of the resin’s volatile fraction identified four monoterpenes: terpinolene, limonene, α-pinene and α-phellandrene.ConclusionThese results provide resources for further studies to identify the molecular bases of the main aroma compounds and new biotechnological approaches to their production.

Ergosterol Synthesis

Terpenes represent the biggest group of natural compounds on earth. This large class of organic hydrocarbons is distributed among all cellular organisms, including fungi. The different classes of terpenes produced by fungi are mono, sesqui, di- and triterpenes, although triterpene ergosterol is the main sterol identified in cell membranes of these organisms. The availability of genomic data from members in the Ceratocystidaceae enabled the detection and characterization of the genes encoding the enzymes in the mevalonate and ergosterol biosynthetic pathways. Using a bioinformatics approach, fungal orthologs of sterol biosynthesis genes in nine different species of the Ceratocystidaceae were identified. Ergosterol and some of the intermediates in the pathway were also detected in seven species (Ceratocystis manginecans, C. adiposa, Huntiella moniliformis, Thielaviopsis punctulata, Bretziella fagacearum, Endoconidiophora polonica and Davidsoniella virescens), using gas chromatography-mass spectrometry analysis. The average ergosterol content differed among different genera of Ceratocystidaceae. We also identified all possible terpene related genes and possible biosynthetic clusters in the genomes used in this study. We found a highly conserved terpene biosynthesis gene cluster containing some genes encoding ergosterol biosynthesis enzymes in the analysed genomes. An additional possible terpene gene cluster was also identified in all of the Ceratocystidaceae. We also evaluated the sensitivity of the Ceratocystidaceae to a triazole fungicide that inhibits ergosterol synthesis. The results showed that different members of this family behave differently when exposed to different concentrations of triazole tebuconazole.

Myrtle rust caused by the pathogen Puccinia psidii is a disease of plants in the Myrtaceae that is currently not known to be present in New Zealand Its origin is Central/ South America but it has steadily spread around the world and is now found in Australia All New Zealand Myrtaceae species including indigenous species are at risk from myrtle rust infection but the extent of the impact on plant health is not known While the potential economic and environmental impacts of myrtle rust establishment in New Zealand have been well documented this paper explores potential sociocultural consequences for M257;ori All indigenous Myrtaceae species can be considered as taonga (or treasure) by M257;ori who have and continue to use the properties of some species in many ways (both tangible and intangible) Preparedness and response plans for a myrtle rust incursion in New Zealand should consider the values that M257;ori derive from these plants
