Sequences for Climate Resilient Rice Crops

  • A genetic resource to increase rice adaptation to warming nights, which involves the regulation of grain weight and grain number per plant
  • Mitigates yield losses associated with rising temperatures
  • Generation of novel and useful cultivars, varieties, and lines

Abstract

Rice sequences involved in grain weight under high temperature conditions

Technology Description

This technology is rice sequences involved in grain weight under high temperature conditions and a method of making a mutant rice plant. High nighttime temperature (HNT) stress limits rice yield by reducing grain quality, weight and size/fertility. Under HNT stress, Lonely Guy-like 1 gene negatively regulates yield and contributes to grain weight variation. Mutation of this gene through gene editing results in heavier rice grains under both high day and night temperature stress. Overall, the identified heat tolerance gene mitigates yield losses by increasing single grain weight and grain number per plant.

Advantages

  • Stability – reduces variation in rice yield
  • Resilient – sustains productivity under high temperature stress
  • Versatile – potential use for other crops, e.g. wheat, corn, sorghum
  • Flexibility – resistant to high day and night temperature stress

Potential Applications

  • Agriculture – novel cultivars, varieties, and lines
  • Research Tool – breeding of climate resilient rice, plant breeding program
