Sorghum accessions Macia (thermo-tolerant), SC224 (cold-tolerant), and RTx430 (heat-/cold-susceptible) respond to heat stress through gene regulation linked to the circadian clock. This linkage is stronger in the tolerant lines.
Africa’s high sorghum production and consumption, coupled with its low grain yield due to phosphorus deficiency in soil, could be improved by enhancing natural soil phosphorus utilization, as demonstrated by research on two sorghum genotypes in Ghana.
This pair of Al-stress-induced WRKY TFs are mainly expressed in the roots of sweet sorghum, where they regulate Al tolerance genes involved in citric acid secretion, callose degradation and cell wall modification.
