Diatom DNA library preparation for Illumina Miseq Sequencing using the rbcL marker gene

Cecile Chardon, Valentin Vasselon, Marine Vautier, Sonia Lacroix, Agnès Bouchez, Frédéric Rimet, Isabelle Domaizon 10.17504/protocols.io.bd94i98w EcoALpsWater This protocol is part of the DNA workflow applied in the Eco-ALpsWater Project, here in particular to characterize the diversity of diatom assemblage in biofilms or plankton samples.Different studies have already revealed the potential of diatom metabarcoding applications for freshwater quality assessment (Kermarrec et al. 2014; Vasselon et al. 2017ab; Visco et al. 2015). The choice of the marker gene and barcode region is key for obtaining relevant inventories of diversity and precise taxonomic assignment. For benthic diatoms, the rbcL gene has proved to be an appropriate taxonomic marker for biomonitoring (Kermarrec et al. 2013, 2014; Vasselon et al. 2017a,b) and a well‐curated barcode reference library is already available to assign species names to rbcL sequences (R‐Syst::diatom, Rimet et al. 2016).For the Eco-AlpsWater project, biolfilms sampled in rivers and lakeshores are collected as described in the dedicated protocols (“Lake plankton sample collection ...” and “Biofilms sample collection ...”) and DNA is extracted as described in the protocol “Biofilms DNA extraction” ; all these protocols are part of the Deliverable D.T1.1.2. We present here the following step in the DNA workflow (i.e. PCR amplification of selected barcodes, and wet lab methods to prepare DNA library for downstream MiSeq Sequencing). This protocol has been used in recent studies (e.g. Keck et al 2018 ; Vasselon et al 2018) where diatoms metabarcoding has been used for ecological assessment of rivers.Several primers were proposed in the literature to characterize Diatom communities through environmental DNA metabarcoding approaches, including the 18S, COI and rbcL barcodes. Following the recommendation provided by Kermarrec et al. 2014, who compared the efficiency of those 3 barcodes to accurately characterize diatom communities from freshwater samples (lakes and rivers), the rbcL barcode will be used within the Eco-AlpsWater project as he provides a good taxonomical resolution.

Angel Justiz-Vaillant 10.17504/protocols.io.bjseknbe A protein that combines the binding capacity of SpA and SpG is not comercially available. It can be easy created in the laboratory by combining these two immunoglobulin-binding proteins to horseradish peroxidase by the periodate method [1]. However, a mixture of SpA and SpG could have the same effect as universal reagent in immunodetection. 1. Vaillant AJ, McFarlane-Andersonv N, Wisdom B, Mohammed W, Vuma S, et al.

High quality DNA extraction from very small individual insects
 
Resource Report
Resource Website
Sam Mugford, Roland Wouters, Thomas C Mathers, Saskia Hogenhout 10.17504/protocols.io.bg6wjzfe Genomic studies of natural populations frequently benefit by having data from single individuals. This approach has a number of advantages: it avoids the risk of accidently pooling together individuals of closely related species, and it enables better resolution of haplotypes by separating non-identical individuals. However, especially in the case of very small invertebrates, recovering sufficient nucleic acid from individual samples can be challenging. Here we present a method suitable for extraction of DNA from single individual aphids (weighing approximately 0.5mg). We are able to recover 100’s of ng of high-quality DNA suitable for whole-genome sequencing using short-read technologies. DNA extraction using Cetrimonium bromide (CTAB) is a tried and tested method, and the protocol presented here is adapted from that of Marzachì et al. (1998). We present some modifications to optimize this popular method to maximize yield and quality from small single insect samples.We have used this method across a range of aphid species, and also other sap-sucking hemipteran insects. It has enabled sequencing and de-novo assembly of a range of species from single individuals collected from the field, and also resequencing of individuals of the model aphid Myzus persicae. This is compatible with the method of ambient storage of dehydrated filed collected samples we describe in Wouters et al. (2020).Marzachì, C, Veratti, F, & Bosco, D (1998).
