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.

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 Agilent qpcr instrument, positioning the A1 well in the top left corner.

Remove the seal from the Decontamination Plate carefully (pay attention not to spill any liquid). Add 11.25µL of probe MM to each of the corresponding detection assay wells in the spun-down decontamination 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. Note: Check for bubbles at the bottom of the wells (bubbles on the surface of the liquid is acceptable). If bubbles remain in the bottom of the wells, spin-down for another minute Re-label the plate as qpcr Plate_[date] Place the sealed plate onto the Agilent qpcr instrument, positioning the A1 well in the top left corner.

10 Page 10 of 10 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.
