Ví dụ
What we found is that certain genes are only on in the pitcher leaf, or preferentially (ưu đãi) on in the pitcher leaf, and that some of these very likely have to do with the trap (bẫy) development.
The carnivorous pitcher plant Darlingtonia californica releases water into the tall vases of its leaves, creating deathtraps (chỗ độc) where insect prey drown (chết ngạt). Water in a pitcher leaf starts clear. But after about a week, thanks to bacteria, it turns “murky brown to a dark red and smells horrible,” says David Armitage of the University of Notre Dame in Indiana.
Bacterial populations in a pitcher leaf are akin (giống với) to those in a mammal gut or bovine rumen, Armitage’s preliminary analysis finds. The microbes can help digest the prey as well as catch it, he says.
