It is a simple two-step protocol, which is flexible and is automation compatible. FemINDICAtor plant gender detection kit uses a multiplexing strategy with an internal plant DNA reaction control to ensure accurate detection of plant gender for every reaction. Unlike other techniques, this multiplexing strategy verifies the performance of the assay when detecting gender, resulting in the minimization of false negatives due to reaction setup errors or failing experimental conditions.

Proceed directly to real-time quantitative PCR (qpcr) using a multiplex system of primers to detect the gender of the plant sample. Below is a simplified depiction of the qpcr assays. The forward and reverse primers have universal primer tails to enable potential Next Generation Sequencing of resulting products.

Begin with a 10% bleach wipe down of the workspace, including the bench top and all equipment being used (except the Bio-Rad CFX96 Touch TM Real-Time System and the Bio-Rad Personal PC). 2. Remove decontamination reagents and positive controls for the tested assays from the -20 o C freezer Decon Buffer and positive control Allow tubes to defrost at room temperature. Once defrosted, place tubes on ice Decon Enzyme Place directly on ice. 3. Before preparing the reaction, invert or vortex the tubes and spin-down the reagents Decon Buffer and Positive Control Vortex quickly followed by a pulse spin down in a micro centrifuge Decon Enzyme Invert the tube 5 times, followed by a pulse spin-down in a micro centrifuge Return all reagents to the ice. Do NOT vortex. 4. Begin with making 1Unit/µL stock of Decon Enzyme Label a 1.5ml tube 1:10 Decon Enzyme 4.2. Label a 1.5ml tube 1:10 Decon Buffer 4.3. Make a 1:10 dilution of Decon Buffer with H 2 O by adding 1ul of Decon Buffer into 9ul H 2 O Make a 1:10 dilution of 10 Unit/µL Decon Enzyme with previously diluted Decon Buffer. For every 1µL of 10 Unit/µL Decon Enzyme dilute with 9µL of diluted Decon Buffer. Note: It is best to add the largest volume reagent first, in this case Decon Buffer 4.5. Once combined, slowly tip mix or invert the tube 5 times Pulse spin-down in a micro centrifuge Return all reagents to the ice. 5. Make a master mix using the table below, labeling a 1.5ml tube as Decon MM Reagent 1 Reaction 24 Reactions (plus 2 48 Reactions (plus 4 excess rxn) excess rxn) Decon Buffer 0.75µL 19.5µL 39µL Diluted Decon Enzyme (1Unit/µL) 0.75µL 19.5µL 39µL H 2 O 1µL 26µL 52µL Total 2.5µL 65µL 130µL 5.1. The number of reactions must include a positive and negative control. For the positive control, make a 1:10 dilution. o 1ul of Positive Control (found in the kit) dilute with 9ul of H 2 O (found in the kit). For the negative control, use H 2 O (found in the kit). Note: It is best to add the largest volume reagent first, in this case the H 2 O Place the extraction plate on the magnet Use a new 96 well optical qpcr plate and label the plate Decontamination Plate_[date]. Add 2.5ul of Decon MM to each sample well, positive control well, and negative control well in the qpcr plate Remove the seal from the Extraction Plate and transfer 5uL of each sample into the corresponding well in the qpcr plate. Keep the extraction plate on the magnet when aspirating the 5uL Add 5uL of the diluted Positive Control to the corresponding well. Then add 5uL of water to the corresponding Negative Control well. Note: ALWAYS use a fresh tip for every liquid transfer into the qpcr plate Tip mix all wells by pipetting up and down 2 times. 6. Seal the plate with the adhesive seal, making sure to completely seal the plate wells using a pen or flat object to slide back and forth along the seal Spin down for at least 1 minute in the plate micro centrifuge Label the plate as Decontamination Plate [date] Place the sealed plate onto the Bio-Rad qpcr instrument, positioning the A1 well in the top left corner.

11 Page 11 of 11 Glossary and Definitions Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms. Polymerase Chain Reaction (PCR) is a technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. A fluorophore is a fluorescent chemical compound that can re-emit light upon light excitation. The Negative Controls are the samples where no Cq is expected. It helps to ensure that all Assay specific reactions are clean of contaminates. The Positive Control is the sample where a Cq is expected. It helps ensure that the FemINDICAtor Plant Gender Detection assay is working correctly. The gender specific Positive Control is targeting the male (Y) chromosome using the FAM flourophore. The Internal Control is added to every sample where a Cq is expected. It ensures the effectiveness and efficiency of each reaction. The internal control is targeting a Single Copy Control Gene or SCCG, using the HEX flourophore.
