Surviving future droughts will be essential this century.
Have you ever gone on vacation and forgot to water your plants—only to come back to your home and find them looking like they’re dead—or at least on the utter brink? But after a quick drink they’re suddenly brought back to life, with a strong green color and an arching height once more. Scientists have always been fascinated by the ability of plants to survive months deprived of the necessities to survive, then return to full health almost overnight.
The findings could point to a way for humans to engineer plants such that these genes can confer drought tolerance to many other plant species of interest, especially critical crops like wheat that will struggle to survive worsened climate change as the century rolls on.. Most people know from high school biology that most animals have two copies of each chromosome, one from each parent. Butchromosomes.
If scientists can figure out how to keep these genes active, it would safeguard them from months of drought later on. That is much easier said than done—and of course, networks of genes operate differently from cell to cell and species to species. But the new insights open the door for further study into what we can do to protect crops and plant life from a certain future of extreme temperatures and fewer bouts of rainfall.
