New discovery of adaptive function of plants

Plants have the function of regulating the growth state according to the four-season temperature change, so what do they rely on to recognize the temperature change of the outside world?

A recent study by British scientists at the John Innes Center showed that in the gene class of plants there is a very special substance, the histone H2A.Z protein is considered a 'thermometer' of plants. This new finding has a great effect to help researchers cultivate new varieties that can better adapt to climate change.

The report, published in the latest issue of Digital Cells, says scientists have intervened with genetic engineering to make the plant Arabidopsis thaliana and make it possible to emit as much light under the environment. The temperature is getting higher and higher. The results showed that scientists discovered a type of histone H2A.Z protein that is thought to be a 'thermometer' of plants.

As the growth temperature of plants grows, the histone H2A.Z protein binds to DNA, making some genes ineffective, thereby inhibiting plant growth. In contrast, when the temperature rises, the histone H2A.Z protein is released from DNA and the relevant genes can be effective, directing the growth of plants.

Scientists believe that some plants may bloom early or late depending on the warm or cold weather and this is under the control of the system.

However, if the mutant histone H2A.Z protein is mutated, it may make the plant unrecognizable to outside temperature changes. Moreover, since plants cannot move in addition to the fact that they cannot adapt quickly to a region's temperature change, they are at risk of extinction.

Scientists hope that after understanding the characteristics of the plant's temperature control system, scientists will be able to grow many new plants that can better adapt to gas changes. post. /.
