Analysis of the workers head transcriptome of the Asian subterranean termite, Coptotermes gestroi

Abstract: The lower termite, Coptotermes gestroi (Isoptera: Rhinotermitidae), is originally from Southeast Asia and has become a pest in Brazil. The main goal of this study was to survey C. gestroi transcriptome composition. To accomplish this, we sequenced and analyzed 3003 expressed sequence tags (ESTs) isolated from libraries of worker heads. After assembly, 695 uniESTs were obtained from which 349 have similarity with known sequences. Comparison with insect genomes demonstrated similarity, primarily with genes from … Show more

“…Potential cellulolytic enzymes were identified using this criteria, such as the match to probable β-glucosidase (GH3) from Dictyoglomus turgidum , two GH7 protein matches, one derived from Pleurotus sp . and another from the uncultivated symbiotic protist Hodotermopsis sjoestedti , as well matches to GH9, from Reticulitermes flavipes and C. formosanus , which are endogenous cellulases from termites [19,22-25]. Two protein matches with high confidence were assigned to CBM families 6 and 27, derived from Salinispora arenicola and Thermotoga sp ., respectively (Additional File 1).…”

“…Caste-regulatory primer pheromones and the social environment have also been studied in the same context ( Tarver et al, 2010 ; Sen et al, 2013 ). Other studies have included tissue-directed subtractive hybridizations, random/ de novo cDNA library sequencing and/or cDNA oligonucleotide microarrays to reveal caste-biased gene expression ( Weil et al, 2009 ; Ishikawa et al, 2010 ; Leonardo et al, 2011 ; Hojo et al, 2012 ; Huang et al, 2012 ; Husseneder et al, 2012 ; Terrapon et al, 2014 ). The over-arching themes emerging from this work include caste and morphogenesis-associated gene expression, endocrine signaling, vitellogenesis, reproduction-related processes, and regulatory mechanisms that maintain juvenile worker states in lower termites.…”

“…C. gestroi has protists and bacteria in its hindgut and it is capable to produce several carbohydrate-active enzymes, however, the occurrences of these enzymes were only reported throughout biochemical assays and proteomic data (Franco Cairo et al, 2011 ; Lucena et al, 2011 ). Moreover, CAZy genes in this termite specie were only described for endogenous endo-glucanase ( Cg EG1-GH9) and β-glucosidase ( Cg BG1-GH1) (Leonardo et al, 2011 ; Franco Cairo et al, 2013 ). Recently, a metagenomic approach in C. gestroi 's gut provided only insights in the CAZy gene repertoire for the free-living bacteria (Do et al, 2014 ), thus, the metatranscriptomic and the metaproteomic profile of CAZy and PAD enzymes endogenously synthesized by C. gestroi as well as by their symbiotic protists remains unclear.…”
