No word on how the rice tastes 😉
When it comes to major anthropogenic sources of methane (an important greenhouse gas), livestock and leaky natural gas wells and pipelines might come to mind. However, rice cultivation is also among the largest sources. Microbes in wetlands, where water saturation leads to low-oxygen conditions, produce most of the world’s methane, and rice paddies are essentially human-controlled wetlands.
For the more biologically minded, you may want to go read the paper because it isn’t clear from the article that the “barley gene” is actually a transcription factor. Which is way cool because of all the genes I would expect to fail when moved from one species to another, transcription factors are pretty high on the list.
For the non-biologists in the room, transcription factors are the “volume knobs” of the gene world and it looks like these folks added a new one that goes to 11.
