Global warming and food security are preeminent worldwide concerns. Various crop plants are exposed to heat stress during critical reproductive stages, having a devastating impact on yield. The cover illustration shows that redox-engineered maize plants, through constitutive ectopic expression of a single gene coding for the monothiol glutaredoxin S17 (AtGRXS17), display robust thermotolerance without any adverse growth effects during reproductive and grain-filling stages, resulting in large yield increases in both greenhouse and fi eld conditions. Cover illustration refers to the article in this issue (Park et al., 1819–1832).
