Project description:BACKGROUND: Western flower thrips are considered the major insect pest of horticultural crops worldwide, causing economic and yield loss to Solanaceae crops. The eggplant (Solanum melongena L.) resistance against thrips remains largely unexplored. This work aims to identify thrips-resistant eggplants and dissect the molecular mechanisms underlying this resistance using the integrated metabolomic and transcriptomic analyses of thrips-resistant and -susceptible cultivars. RESULTS: We developed a micro-cage thrips bioassay to identify thrips-resistant eggplant cultivars, and highly resistant cultivars were identified from wild eggplant relatives. Metabolomic profiles of thrips-resistant and -susceptible eggplant were compared using the gas chromatography-mass spectrometry (GC-MS)-based approach, resulting in the identification of a higher amount of quinic acid in thrips-resistant eggplant compared to the thrips-susceptible plant. RNA-sequencing analysis identified differentially expressed genes (DEGs) by comparing genome-wide gene expression changes between thrips-resistant and -susceptible eggplants. Consistent with metabolomic analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of DEGs revealed that the starch and sucrose metabolic pathway in which quinic acid is a metabolic by-product was highly enriched. External application of quinic acid enhances the resistance of susceptible eggplant to thrips. CONCLUSION: Our results showed that quinic acid plays a key role in the resistance to thrips. These findings highlight a potential application of quinic acid as a biocontrol agent to manage thrips and expand our knowledge to breed thrips-resistant eggplant.

Project description:The EFSA Panel on Plant Health (PLH) performed a pest categorisation of Thrips palmi (Thysanoptera: Thripidae), for the EU. T. palmi is listed in Annex IAI of 2000/29 EC. Using molecular methods, cryptic speciation has been shown although no new species from the group have been formally described. Here, we consider T. palmi sensu lato as a defined species native to southern Asia, which has spread to tropical and subtropical countries in Asia, the Pacific, North, Central and South America, Africa and Australia. T. palmi has been reported from many different hosts in 20 botanical families; Cucurbitaceae, Solanaceae and Orchidaceae are of primary importance. T. palmi has been intercepted many times on plants from these families. Wild and cultivated hosts are widespread in the EU. However, as a subtropical and tropical species, only a small area of the EU provides climatic conditions where establishment may be possible outdoors. Several host plants are cultivated in glasshouses where conditions may be more favourable for establishment in year-round crops. There have been past outbreaks of T. palmi in EU glasshouses and outdoors in Portugal. T. palmi causes feeding and oviposition damage and populations in Asia are competent vectors of tospoviruses. Impacts could occur on many hosts, especially Cucurbitaceae, Solanaceae and ornamental plants particularly in glasshouses. Phytosanitary measures aim to prevent the entry of T. palmi specifically on cut flowers of Orchidaceae and fruits of Momordica and Solanum melongena. The species meets all the criteria assessed by the PLH Panel to satisfy the definition of a Union quarantine pest, while it does not satisfy all the criteria for it to be regarded as a Union regulated non-quarantine pest (RNQP).

Project description:The melon thrips, Thrips palmi is a serious pest and vector for plant viruses on a wide range of economically important crops. DNA barcoding evidenced the presence of cryptic diversity in T. palmi and that warrants exhaustive molecular studies. Our present study is on decoding the first complete mitochondrial genome of T. palmi (15,333 bp) through next-generation sequencing (NGS). The T. palmi mt genome contains 37 genes, including 13 Protein coding genes (PCGs), two ribosomal RNA (rRNAs), 22 transfer RNA (tRNAs), and two control regions (CRs). The majority strand of T. palmi revealed 78.29% A+T content, and 21.72% G+C content with positive AT skew (0.09) and negative GC skew (-0.06). The ATN initiation codons were observed in 12 PCGs except for cox1 which have unique start codon (TTG). The relative synonymous codon usage (RSCU) analysis revealed Phe, Leu, Ile, Tyr, Asn, Lys and Met were the most frequently used amino acids in all PCGs. The codon (CGG) which is assigned to Arginine in most insects but absent in T. palmi. The Ka/Ks ratio ranges from 0.078 in cox1 to 0.913 in atp8. We observed the typical cloverleaf secondary structure in most of the tRNA genes with a few exceptions; absence of DHU stem and loop in trnV and trnS, absence of DHU loop in trnE, lack of T-arm and loop in trnN. The T. palmi gene order (GO) was compared with ancestral GO and observed an extensive gene arrangement in PCGs, tRNAs and rRNAs. The cox2 gene was separated from the gene block 'cox2-trnL2' in T. palmi as compared with the other thrips mt genomes, including ancestor GO. Further, the nad1, trnQ, trnC, trnL1, trnV, trnF, rrnS, and rrnL were inversely transpositioned in T. palmi GO. The gene blocks 'trnQ-trnS2-trnD' and 'trnN-trnE-trnS1-trnL1' seems to be genus specific. The T. palmi mt genome contained 24 intergenic spacer regions and 12 overlapping regions. The 62 bp of CR2 shows the similarity with CR1 indicating a possible duplication. The occurrence of multiple CRs in thrips mt genomes seems to be a derived trait which needs further investigation. Although, the study depicted extensive gene rearrangements in T. palmi mt genome, but the negative GC skew reflects only strand asymmetry. Both the ML and BI phylogenetic trees revealed the close relationships of Thrips with Scirtothrips as compared to Frankliniella. Thus, more mt genomes of the diverse thrips species are required to understand the in-depth phylogenetic and evolutionary relationships.
