与heterocyst相关的网络例句 [注：此内容来源于网络，仅供参考]

In iron-deficient cells, photosynthetic pigments content decreased, efficiency of photosynthesis was low, With the increase of the concentration of the iron-chelator 2, 2'-Dipyridyl in media, Fv/Fm decreased, indicating photoinhibition increased, the results were consistent with previous research; Heterocyst induction had one delayed time dependent on the status of iron-deficiency, More severe of the iron-deficiency condition, more late of the heterocyst induction, It is possible that certain iron-related genes may directly regulate heterocyst development; under different iron limitation conditions, Protein pattern were different, more serious of the iron-deficiency conditions, less bands of the protein pattern, We could not find the iron-deficiency induced protein; In general the toxic effects of ROS were potentiated by excess iron, But our results revealed that even under iron-deficiency conditions, Oxidative damage existed.

铁限制的细胞光合色素含量下降，光合作用能力下降，随着铁螯合剂2，2'-dipyridyl浓度的增加，叶绿素荧光F〓／F〓逐渐降低，显示光抑制变强。与前人的研究结果相似；依赖铁缺失状态，异形胞诱导有一段推迟的时间，铁缺失越严重，诱导越迟，推断某些铁相关的基因会直接调节异形胞发育；在不同铁营养条件下，蛋白质图谱的变化趋势很明显，缺铁越严重，则蛋白质谱带数愈少，但本文未能找到特异诱导蛋白；一般认为铁过量情况下ROS产生加强，本文结果显示即便在铁缺失条件下，也有氧化胁迫伤害，而且缺铁越严重，活性氧伤害越大。

In conclusion, we have conducted the in-depth analyses of HetR protein function in the molecular mechanism of heterocyst differentiation and pattern formation in Anabaena. Our results show that HetR/PatS interaction plays a key role in heterocyst differentiation and pattern formation.

综合以上内容，我们对HetR蛋白在蓝细菌异型胞分化与格式形成过程中的分子调控机制作了较为深入的研究，我们的研究显示HetR/PatS的相互作用在异型胞分化与格式形成中起重要作用。

The result showed that one mutant was unable to differentiate heterocyst, three formed heterocysts but still could not maintain normal growth, four growed slowly with heterocyst differentiation.

结果显示，有一个突变株不能分化异形胞；三个突变株可以形成异形胞，但在缺氮的条件下仍不能维持生长；4个突变株可以分化异形胞，但在缺氮条件下生长缓慢。

heterocyst：异形细胞

5)营养极为简单,不需要维生素,以硝酸盐或氨作为氮源,多数能固氮,其异形细胞(heterocyst)是进行固氮的场所. 6)分泌粘液层,荚膜或形成鞘衣,因此具有强的抗干旱能力. 7)无鞭毛,但能在固体表面滑行,进行光趋避运动. 8)许多种类细胞质中有气泡,

heterocyst：异形胞

有一些蓝藻的藻丝上常含有特殊细胞,叫异形胞(heterocyst). 异形胞是由营养细胞形成的,一般比营养细胞大,在光学显微镜下观察,细胞内是空的. 形成异形胞时,细胞内的贮藏颗粒溶解,光合作用片层破碎,形成新的膜,

heterocyst：异型细胞

有些可生成異型細胞(Heterocyst)或厚壁孢子(Akinete),其為一種內生孢子,可儲藏養分或由此萌芽產生新個體. 異型細胞具有固氮機制,可吸收空氣中游離氮轉化為有機物,增加土壤肥力. 異型細胞的數量、位置常是藍藻分類的重要特徵.
