Do you know how plants sense temperature?

“ World April wheatgrass, yamadera peach blossom in full bloom. ” Said is the peach blossom open later than below, we all know that is caused by the mountain and the temperature of the different below. That you ever wonder why some plants as the change of temperature in advance or delay flowering? Actually very simple, because the plants have a & other; The thermometer & throughout; ！ British scientists solved through research in advance or delay the flowering plants. Using arabidopsis thaliana experiment, this is a kind of flowering plants, in the role of botany like rats in medicine and flies in genetics, called & other; Fruit flies in plants & throughout; 。 They analyzed samples of all plant arabidopsis gene, found one called H2A. Z of histone is plants & other; The thermometer & throughout; 。 This group of proteins and DNA binding, wrapped around it, you can control which gene is open. Scientists will be after this group of protein extracted from plants, plant shows its all gene seems to be in high temperature, even if it is cold. Scientists believe that this group of proteins is an important reaction temperature regulator. When the plant growth environment temperature is lower, it can bind to the DNA, making some genes can not play a role, to inhibit the growth of plants; When the temperature rises, it will & other; Loosen the & throughout; DNA, genes can play a role, guide the plants grow faster. Because plants cannot move, if it does not quickly adapt to the temperature changes, somewhere there is the danger of extinction. Scientists hope that through this research, a deep understanding of the temperature control system of plants, and then develop a more able to adapt to the new plant varieties of climate change. So the plant & other; The thermometer & throughout; Is important!
