Arrange the sentences into the correct order.
Put the sentences in the correct order:
- Once released to farmers, these hardier varieties produced stable yields even in seasons when neighboring fields of conventional crops failed entirely.
- This trait allows the resulting plants to close their leaf pores earlier in a dry spell, conserving water reserves that ordinary crops would already have exhausted.
- Once a promising drought-tolerance gene was identified, breeders crossed it into commercial varieties over several generations of careful selection.
- In response, agricultural scientists began searching wild relatives of staple grains for genes that allow plants to survive extended dry spells.
- Farmers in arid regions have long struggled with crop failures whenever rainfall arrives late or not at all.
