隐花色素

UV-B、隐花色素和光敏色素信号传递途径之间的相互作用调控CHS表达。

Interactions within a network of UV-B , cryptochrome and phytochrome signaling pathways regulate CHS expression .

对突变体分析表明，红光下光敏色素B，远红光下光敏色素A，蓝光下隐花色素1起主要调节作用。

The response was essentially controlled by phytochrome B in red light , phytochrome A in far red light and cryptochrome 1 in blue light . The coaction was also existed among different photoreceptors by analyzing mutants .

利用不同的光受体缺失突变体研究光受体的作用表明，隐花色素1、光敏色素A和光敏色素B参与调节了光对下胚轴的抑制作用。

Different photoreceptor null mutants were used to research the action of photoreceptor , and the results indicated that cryptochrome 1 , phytochrome A and phytochrome B participate in the modulation of light inhibition process of hypocotyls elongation .

隐花色素（cryptochrome）是一类对UV-A/蓝光作出应答的光受体。

Cryptochrome is one of the UV-A / blue light photoreceptors .

但是，隐花色素是否在维持人类的生物钟上有重要作用呢？

But can it do more than keep the circadian clock ticking ?

光敏色素和隐花色素等是光周期反应的受体。

Phytochrome and cryptochrome are the receptors of photoperiod response .

植物的隐花色素及其光信号转导

Plant Cryptochrome and Its Light Signal Transduction

本研究为拟南芥隐花色素的功能研究提供了一个新的突变体。

The results provide a new mutant for genetic studies of cryptochrome functions in Arabidopsis thaliana .

为了找到问题的答案，科学家把果蝇身上的隐花色素基因敲除，插入人类的隐花色素基因。

To find out , researchers took out fruit flies ' usual cryptochrome gene and inserted the human version .

隐花色素在人体和动物体内也有表达，并且已被证明可以调节生物钟。

Cryptochromes are present in humans and animals as well and have been proven to regulate the mechanisms of the circadian clock .

不过，人类隐花色素不是负责感光，似乎也不能让人类具有感应磁场的非凡力量。

Human cryptochrome doesn 't require light to function , though - and it doesn 't seem to give us a phenomenal sensitivity to magnetic fields .

在植物中，隐花色素是吸收和处理蓝光的光感蛋白，而它具有促进生长、幼苗发育和茎叶的扩展的作用。

In plants , cryptochromes are photoreceptor proteins which absorb and process blue light for functions such as growth , seedling development , and leaf and stem expansion .

结果，转基因果蝇在光照条件下依然具有感应磁场迷宫的能力，这也说明人类隐花色素蛋白依然可以作为光敏磁场感应器。

And the transgenic flies had no problem navigating a magnetic maze when exposed to light - indicating the human protein can still serve as a light-sensitive magnetic sensor .

隐花色素主要存在于视网膜中，但是他们在身体的很多靠近表皮的组织也有表达。

Although cryptochromes are mainly found in the retina of the eye , they are also present in many different tissues of the body that are close to the surface .

隐花色素的存在暗示也许在某些条件下，人类可以感知磁场，或者，进化使得隐花色素在我们这样的新诞生物种体内负责新的任务。

Which suggests we might be able to see magnetic fields in some way . On the other hand , evolution might have just given cryptochrome a new job in new organisms .

数十年来，研究人员一直在研究动物身上的这种现象，他们发现狗、狐狸和熊的眼睛中都有磁场传感分子隐花色素--该研究在今年早些时候被发布。

For decades , researchers has been studying this phenomenon in animals and discovered that dogs , foxes and bears also have the field-sensing molecule cryptochrome in their eyes - this work was published earlier this year .

近年来，对拟南芥及其它植物的分子遗传研究，在隐花色素和向光素的分子、基因和蓝光信号转导方面取得了显著进展。

In recent years , great progress has been made in the molecular genetic research of Arabidopsis and other plants , especially in the molecules and genes of cryptochromes and phototropins , and signaling of blue light .

过去的研究认为长距离迁徙动物，在一种名为“隐花色素”的感光蛋白作用下能够感知磁场，即便是果蝇这样的生物，也同样如此。我们人类同样能够合成这种蛋白，如果没有这种蛋白，我们的生物钟就无法运行。

Previous studies suggest long-distance migrators - and even fruit flies - pick up magnetic fields with the help of a light-sensitive protein called " cryptochrome . " We produce cryptochrome too - without it , our circadian clocks would break .

据《科学》杂志报道，其他一些专家则表示，“第六感”来自于铁矿和磁铁矿，有点类似于“指南针”，而其他人则认为“第六感”来源于视网膜中一种被称为隐花色素的蛋白质。

Other experts say this ' sixth sense ' harnesses its power from iron mineral and magnetite to act as ' compass needles ' , while others say it relies on protein in the retina called cryptochrome , reports Science magazine .
