Dataset Information

Metagenomic 16S rRNA amplicon data of gut microbial diversity in three species of subterranean termites (Coptotermes gestroi, Globitermes sulphureus and Macrotermes gilvus).

ABSTRACT: In this paper, we present the metagenomic dataset of gut microbial DNA of the lower group of subterranean termites, i.e. Coptotermes gestroi, and the higher groups, i.e. Globitermes sulphureus and Macrotermes gilvus, in Penang, Malaysia. Two replicates of each species were sequenced using Next-Generation Sequencing (Illumina MiSeq) and analysed via QIIME2. The results returned with 210,248 sequences in C. gestroi, 224,972 in G. sulphureus, and 249,549 in M. gilvus. The sequence data were deposited in the NCBI Sequence Read Archive (SRA) under BioProject number of PRJNA896747. The community analysis showed that Bacteroidota is the most abundant phylum in C. gestroi and M. gilvus, while Spirochaetota is prevalent in G. sulphureus.

Project description:The survival and foraging of Coptotermesformosanus Shiraki in a microbe-rich environment reflect the adaptation of an extraordinary, sophisticated defense mechanism by the nest-mates. We aimed to explore the host pathogen interaction by studying caste-specific volatile chemistry and genes encoding the antioxidant defense of winged imagoes, nymphs, soldiers and workers of Formosan subterranean termites. Qualitative analyses of C.formosanus Shiraki performed by HS-SPME/GC-MS showed considerable variations in the chemical composition of volatile organic compounds (VOCs) and their proportions among all the castes. Winged imagoes produced the most important compounds such as naphthalene and n-hexanoic acid. The antifungal activity of these compounds along with nonanal, n-pentadecane, n-tetradecane, n-heptadecane and methyl octanoate against the conidial suspensions of Metarhiziumanisopliae and Beauveriabassiana isolates enable us to suggest that the failure of natural fungal infection in the nest is due to the antiseptic environment of the nest, which is mainly controlled by the VOCs of nest-mates. In addition, conidial germination of M.anisopliae and B.bassiana isolates evaluated on the cuticle of each caste showed significant variations among isolates and different castes. Our results showed that the conidia of M.anisopliae 02049 exhibited the highest germination on the cuticle of all the inoculated castes. Moreover, we recorded the lowest germination of the conidia of B.bassiana 200436. Caste-specific germination variations enabled us to report for the first time that the cuticle of winged imagoes was found to be the most resistant cuticle. The analysis of the transcriptome of C.formosanus Shiraki revealed the identification of 17 genes directly involved in antioxidant defense. Expression patterns of the identified antioxidant genes by quantitative real-time PCR (qPCR) revealed the significantly highest upregulation of CAT, GST, PRXSL, Cu/Zn-SOD2, TXN1, TXN2, TXNL1, TXNL2, TXNL4A and TPx genes among winged imagoes upon infection with the most virulent isolate, M.anisopliae 02049. Furthermore, soldiers showed the least expression of genes encoding antioxidant defense. Our findings indicated that the volatile chemistry of nest-mates and genes encoding antioxidant defense greatly contribute to the survival and foraging of Formosan subterranean termites in a microbe-rich habitat.
