Selection of Reference Genes for RT-qPCR Analysis Under Extrinsic Conditions in the Hawthorn Spider Mite, Amphitetranychus viennensis.

ABSTRACT: Hawthorn spider mite, Amphitetranychus viennensis Zacher, is an economically important arthropod pest for fruit trees and woody ornamental plants. Extensive and repetitive use of synthetic acaricides has led to the development of resistance in A. viennensis. To understand the molecular basis of pesticide resistance, and to develop genetic-based control alternatives (e.g., RNAi-based biopesticides), a standardized protocol for real-time quantitative reverse transcription PCR (RT-qPCR) is needed. In the proceeding phase of this research, we screened for the internal references for RT-qPCR analysis from a pool of A. viennensis housekeeping genes under the intrinsic conditions, including developmental stage, sex, and diapause. Here, we continued our efforts to search for the reference genes under an array of extrinsic conditions, including temperature, humidity, photoperiod, host plant, and dietary RNAi. The stability of these candidate reference genes was investigated using geNorm, NormFinder, BestKeeper, and ?Ct method, respectively. Finally, RefFinder, a statistical platform integrating all four algorisms, provided a comprehensive list of genes for each extrinsic condition: (1) EF1A, ?-tubulin and Actin3 were the best candidates for temperature, (2) GAPDH, 18S, and Actin3 were the most stable genes for humidity, (3) V-ATPase B, Actin3, and 18S were the top reference genes for photoperiod, (4) GAPDH, V-ATPase B, and ?-tubulin were recommended for host plants, and (5) GAPDH, V-ATPase B, and RPS9 were the top choices for dietary RNAi. Overall, V-ATPase B, GAPDH, and Actin3 were the most commonly selected reference genes in A. viennensis regardless of the experimental conditions, including both intrinsic and extrinsic. Information present here lays the foundation for the genomic and functional genomic research in A. viennensis.

Project description:Hawthorn spider mite, Amphitetranychus viennensis Zacher, is one of the most devastating pests of deciduous fruit trees. The overall goal of this research is to develop a standardized protocol for real-time quantitative reverse transcription PCR (RT-qPCR) analysis in A. viennensis following the MIQE (minimum information for publication of Quantitative real time PCR experiments) guidelines. Based on the previous knowledge, we hypothesized that internal references for RT-qPCR analysis reside in housekeeping genes (HKGs). To test this hypothesis, we examined the stability of nine HKGs from A. viennensis, including 18S ribosomal RNA (18S), 28S ribosomal RNA (28S), Elongation factor 1-alpha (EF1A), Actin3, V-ATP vacuolar-type H+-ATPase (V-ATPase), ?-tubulin (?-tubulin), Ribosomal protein L13 (RPL13), 40S ribosomal protein S9 (RPS9), and Glyceraldehyde 3-phosphate dehydrogenase (GAPDH). The expression profile of these candidates under intrinsic conditions was evaluated by a panel of computational programs, including geNorm, Normfinder, BestKeeper, and ?Ct method. Based on RefFinder, a comprehensive software integrating all four above-mentioned algorithms, V-ATPase, Actin3, and GAPDH are the top three reference genes, which are stably expressed across all the intrinsic conditions, including developmental stage, sex, and diapause. In addition, we compared reference genes recommended for different developmental stages among the nine cell-content feeding arthropods, including four spider mites, A. viennensis, Tetranychus urticae, Tetranychus cinnabarinus, and Panonychus citri, and five hemipterans, Myzus persicae, Aphis gossypii, Toxoptera citricida, Lipaphis erysimi, and Sogatella furcifera. Not surprisingly, rRNAs and ribosomal proteins, the most abundant RNA species, is the top choice, and follows by EF1A, Actin, GAPDH, and tubulin. Information present here lays the foundation for the genomic and functional genomic research in cell-content feeding arthropods in general and A. viennensis in particular.
