Plants in each season can be exposed in great temperature changing, and night and day temperatures also have very big difference. In order to deal with these changes, plants need to perceive the ambient temperature, and subsequently and adjust its growth.
Now, scientists found that the plants could have a built-in thermometer, they use their control its growth, which means people perhaps is expected to cultivate can resist climate change crops. On this basis, the British biologists have identified a likely to cultivate can cope with the weather changes effect of plants are very crucial "thermometer" gene. The study, published in the latest issue of the journal cell.
Plants can feel 1 degrees Celsius temperature difference. Climate change has caused the significant effects -- some plant flowering, thus changing the global species distribution. Although scientists in hundreds of years ago have known that the influence of temperature on plants, but so far, how the temperature was plant of perception is still a mystery.
In order to find the answer to the question, British Norwich city John Innes center and dr. Phil Vinod Kumar Wigge doctor analyzed samples plant arabidopisis thaliana all the genes, in order to understand which genes by warmer temperature open.
They will be one of the genes connected to send a 2-for-one genes, thus created in temperature increases hair 2-for-one plants. Using this method, the researchers can shield off can’t perceive proper temperature of mutants.
One of the mutant particularly interesting, because it lost correct perception temperature ability. The researchers found that the plant act like its surrounding has been very hot - when the plant surrounding area or hot or cold, it will send luminescence.
Kumar discovered this plant variant plants, he said: "this plant made me feel very surprise, they are like in high temperature plants the same growth, even as we put temperatures reduce as well."
This plant has a affect a special category histone work of a single defect. These proteins and DNA binding, and in its material around the parcel, so can control which genes are open.
Notable is, when this special histone no longer merges into DNA, plants shows its all genes seem in high temperature, even the cold. This makes scientists believe that this special group of protein is vital temperature reaction regulator.
Histone variant in lower temperature by more tightly bound plant’s DNA, thereby can work as well as the clinical thermometer, prevent gene is open. When the temperature increases, the histone lose grip, begin to release DNA, allowing the gene is open.
Researchers found that feeling temperature control a variant gene, this gene through to help accelerate flowering plants adapt to climate change.
Plants must continue to adapt to the surrounding environment, because they can’t move around. Therefore no adjust flowering species will be extinct in the local with high.
Understand how plants use temperature sensing, makes scientists can check the different species how to further raise the global temperatures to react. Wigge said: "we may use these crops genetically alter perceived temperature way. If you can do so, maybe we can cultivate to combat climate change crops."
 

How to determine the baby fever

Because is the novice mom, so baby fever often judge the occurrence of two mistakes: one is when she saw the baby some wrong, often by hand touch child’s forehead and small children to judge whether fever, if the baby’s skin burning, mother will think is calorific. This judge of children is not very accurate, feer because mother’s hand is not accurate measure temperature, thermometer.
2 it is some mothers need not hand in children’s forehead, but use clinical thermometer measurement baby’s body temperature, when temperature more than 37 degrees Celsius, think children fever, then hurriedly zone children to hospital. Actually, this approach is not appropriate, fever refers to the baby exceptional increasing temperature, so only when the temperature over 37.1 degrees Celsius can think baby fever.
In addition, the best and the most effective way is to use lips gently on baby’s temporal location, see if it is better than his lips to the high temperature, temperature markedly higher than if lips, that is about to take the baby to the hospital for inspection.
