Flavonoids’ presence in sorghum roots may lead to frost-resistant crop

  • That is important because sorghum is a crop that can respond to climate change because of its high water- and nitrogen-use efficiency.
  • In this study, researchers found evidence that plant genetic variation influences root flavonoids and the composition of the soil microbial community, and that low temperatures affect these relationships.
  • Of those “near-isogenic” lines of sorghum — alike except for two genes involved in the production of flavonoids — one set of lines inherently produced flavonoids, the second set lacked genes to produce flavonoids, and the third type only produced flavonoids when the plants were exposed to stress such as frost and fungal pathogens.
