Molecular mapping and characterization of QTLs for grain quality traits in a RIL population of US rice under high nighttime temperature stress

The analysis of the mapped QTLs and their genetic dissection in the US grown japonica rice genotypes, Cypress and Lagrue at genomic and transcriptomic levels The gene expression profiling using Deseq was performed using data collected under control and heat stress For heat stress:a day/night temperature of 30°C (86°F)/28°C (82.4°F) for 10 h (20:00–6:00) was maintained while the control treatment was set at a day/night temperature of 30°C (86°F)/22.2°C (72°F) until harvest maturity (approximately 18–20% grain moisture content) Comparative gene expression analysis between Cypress and Lagrue to study the effect of high night temperature during grain filling across two genotypes.
