Roses are red, but they've never been blue. They are actually a lot of colors, but they lack the right pigment genes(色素基因)that would make them blue.
But don't worry, if blue is your favorite color, science has the answer. US scientists have said they could make the missing pigment gene in the near future with developments in biotechnology.
The scientists were studying how some medicines affect the liver(肝脏) when they found a human protein that fumed things blue during the process. This may be used to create the world's first - known blue rose.
Scientists have already turned a cup full of bacteria (细菌) blue with an enzyme (生化酶) taken from a person's liver. They're now trying to put this same human gene into roses. Technology also promises to make sure the roe still smells good. Commercial growing has led to many beautiful but dull- smelling roses. Their colors are varied and they last a long time, but they've little fragrance.
Genetic engineers are also trying to get science to fight diseases and insects that affect the world's 120 different rose kinds. These roses are a US $10 billion-a-year business world-wide. The technology may be very useful in gardening, say scientists. “We could try to grow blue cotton, blue anything really. ”said a scientist..
So far, though, it hasn't been easy. They have only managed to get a few blue spots into the stems. “ It's not as easy as you may think. It's going to take more work. ”
They're not alone, an Australian company was set up in 1986 to develop a blue rose. Researchers have tried to put a “blue” petunia gene into rose`. But they have not had much success so far.

Glynis Davis:
I first piled on the pounds when I was in the family way and I couldn’t lose them afterwards. Then I joined a slimming club. My target (aim) was 140 pounds and I lost 30 pounds in six months. I felt great and people kept saying how good I looked. But Christmas came and I started to slip back into my old eating habits. I told myself I’d lose the weight at slimming classes in the new year…but it didn’t happen. Instead of losing the pounds, I put them on. I’d lost will power and tried to believe that the odd bags of fish and chips didn’t make any difference but the scales don’t lie.
Roz Juma:
To be honest, I never weigh myself any more—I’ve learnt to be happy with myself. It seemed to me that 1 would be sorry for every spoonful of tasty food that passed my lips. My idea is simple. You shouldn’t be too much thinking about food and dieting. Instead, you should get on with life and stop dreaming of a super - thin body. This is obviously the size I meant to be end, most of a11.I am happy with it.
Lesley Godwin:
I was very happy after winning Young Slimmer of the Year. I’d look in the mirror unable to believe this slim lady was me! That might have been my problem - perhaps from then on I didn’t pay any attention to myself. Winning a national competition makes everything worse, though, because you feel a complete failure because I’ve put on weight again.
Ros Landford:
Before moving in with my husband Gavin, I’d always been about 110 pounds, but the pleasant housework went straight to my waist and I put on 15 pounds in a year. Every year so often I try to go on a diet…I’m really good on a few days, then end up having the children’s leftover or eating happily chocolate - - - my weakness. I’d like to be slim, but right now my duty is the children and home. I might take more exercise when my kids are older.
