Tannins in plants have health benefits and impact the taste of fruits and drinks like tea and wine. While tannins themselves are well known, no one has ever known how plants actually put them together—until now. A team of researchers from the University of North Texas Department of Biological Sciences just made this major discovery. Now, the research by Chenggang Liu, Xiaoqiang Wang, Vladimir Shulaev and Richard Dixon, recently was featured in the journal, Nature Plants.
"This is one of the most exciting discoveries of my career," says Dixon, Distinguished Research Professor of biology. "I've worked for 35 years on how plants make natural products, and now we've answered a question that has been bothering people for many years."
The researchers studied the gene leucoanthocyanidin reductase, or LAR. Scientists previously thought LAR only helped make the building blocks of tannins, but the UNT research team learned that the gene instead plays an unexpected role in determining how the building blocks of tannins multiply to form long chains. When those building blocks, called epicatechin, are linked in longer chains, they become insoluble, and lose astringency. However, smaller, more soluble tannins can offer humans more health benefits. Understanding how the process works has major scientific implications.

Here's another to think of: how to GM lucerne to stop cows farting and arrest taurinomorphic global warming (no, seriously, TFA says that much).
(and another thing you may not know you don't know: neither sheep nor kangaroos fart; with the same diet, how are they not doing it?)

Nice try, but I call BS:

Kangaroos produce a significant amount of methane, researchers found, just not as much as cows and sheep. Adjusted for body weight, the large marsupials are about as gassy as horses.

For sheep my bet is on the shepherds.

I already know, that's why I never read them.
"with the same diet, how are they not doing it?"
Magnets.
