Description
Quinoa is a highly nutritious seudocereal crop that is not well adapted to heat. Improving understanding of quinoa responses to heat would help expand its cultivation to regions with warmer climates. This study profiled gene expression of quinoa plants from accession QQ74 (PI 614886) treated with high tempreatures during anthesis of the main panicle, which lasted 11 days. Heat was applied in four different treatments to profile gene expression changes from root or shoot heating. Treatments were: 1. control with both roots and shoots at 22°C, 2. heated roots with roots at 30°C and shoots at 22°C, 3. heated shoots with roots at 22 °C and shoots at 35°C, and 4. heated roots and shoots with roots at 30°C and shoots at 35°C. Healthy leaves from 3 plants per treatment were sampled from the mid section of the plants, during the first (day 1) and last day (11) of heat treatment, at Zeitgeber time 2. Gene expression of each of the three heat treatments was compared to control using the Kallisto-Sleuth pipeline. These gene expression profiles of quinoa under heat are made available as a community resource to improve understanding of quinoa responses to heat. Overall design: Quinoa QQ74 (PI 614886) root vs. shoot heating 2x2 factorial design, with 4 treatments: 1. control with both roots and shoots at 22°C, 2. heated roots with roots at 30°C and shoots at 22°C, 3. heated shoots with roots at 22 °C and shoots at 35°C, and 4. heated roots and shoots with roots at 30°C and shoots at 35°C. Heat treatment started at first anthesis and lasted 11 days. Leaf tissue from 3 plants was sampled from each treatment, during days 1 and 11 of heat, for a total of 24 samples analyzed. Each plant was considered a replicate.
