色素

They are involved in phototropism, and in PHOTOPERIODISM, where they are thought to affect phytochrome by transferring light energy from blue to red wavelengths.

它与向光性和光周期有关，一般认为黄素通过把光能从蓝光转移到红光而影响光敏色素。

Usually 1 month of photophobia in dark room is enough to preventticking, pigment deposition and other photosensitive responses.

一般在昏暗房间内避光一个月即可，以免产生搔痒、色素沉着等光敏反应。

They consist of no more than two cells: a photoreceptor cell and a pigment cell.

他们的眼睛中包含的细胞不超过两个：光感细胞和色素细胞。

Objective The retinal pigment epithelium is a vital tissue for the maintenance of photoreceptor function.

目的 视网膜色素上皮(Retinal Pigment Epithelium，RPE)具有复杂的结构和特殊的生理机能。

They are found in all photosynthetic organisms, where they function mainly as accessory pigments in photosynthesis.

它们作为光合作用的辅助色素存在于所有的能进行光合作用的生物体中。

Chlamydomonas cells are also positively phototactic, swimming toward light to increase their photosynthesis rate.but if the light intensity becomes too great.they show negative phototaxis,swimming away to protect their pigments.

衣藻细胞也同样为正趋光，游向有光处以增加其光合作用速率，但是如果光强度过大，它们就会表现出负趋光，游走以保护它们的色素。

Hypocrellins (including hypocrellin A and hypocrellin B), isolated from the parasitic fungus Hypocrella bambusae sacc, are efficient phototherapeutic agents and photosensitizers.

竹红菌素(包括竹红菌甲素和竹红菌乙素)是从竹红菌中提取出来的一类天然光敏色素，属于苝醌类衍生物。

Comparing with phototrophic culture and heterotrophic culture, mixotrophic culture can't influence the inducement synthesizing of pigment but improve the cell concentration of Spirulina, so mixotrophic culture has the potential and particular value in large scale culture. But mixotrophic culture has't come true in commercial production up to the present, it is very important to study the high cell-density mixotrophic culture of Spirulina.

混合营养培养与光合自养及异养培养相比，既可提高微藻细胞密度，又不影响色素等光诱导产物的合成，在大规模培养中具有独特的优势，但至今微藻混合营养培养还没有在商业生产上实现，因此开展螺旋藻高密度混合营养培养工艺的研究显得尤为重要。

The known photoreceptors for UV - A/blue light are eryptochrome 1 and CRY 2, and the phototropism photorecep- tor, phototropin.

已知的蓝光／UV-A受体有隐花色素CRY1和CRY2，向光性受体有趋光素。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
