At Tokyo University, Professor Sachihiro Matsunaga and his team of researchers may have determined how to regenerate plant tissue. The idea comes from trying to revert cells from their specialized state known as unipotent cells back to what’s known as pluripotency (think stem cells). The team at Tokyo University tried to reverse these unipotent cells in the plant Arabidpsis thaliana. They modified histone proteins throughout the entire genome and came to the conclusion that once histone is demethylated, this allows for plants to be regenerative. These histone modifications aimed to demethylate histone H3 by the enzyme LDL3.
According to a separate article on plant regeneration, it’s also possible for plants regenerative capabilities to speeded up as well by supplying hormones. Is it then possible to combine both of these techniques to be able to constantly have plants regenerate tissue? If so, this could open up a ton of possibilities to increase our food supply and hopefully come closer to ending world hunger.
