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。

By exploring the different components of the lysis buffer and optimize the 2-DE conditions, established the best proteomics technical system for Populus euphratica's heteromorphic leaves, while take the heteromorphic leaves in the same blanche as the test materials to find differences between the protein expressions of the leaves.

The wood structures of Lauraceae were characterized by most diffuse porous; most pores solitary, less multiple and cluster pores; simple and scalariform perforation with few bars; most solitary pore; alternate intervessel pitting; most of rays multiseriate, less uniseriate; all of rays heterogeneous, mostly heterogeneous Ⅲ and Ⅱ type rays; most of axial parenchyma paratracheal type, less banded or marginal type; oil cell and mucilage cell in axial parenchyma cell or ray cell; mostly fiber tracheid and libriform fiber, less septate fiber.

结果表明：除檫木外，其它木材的管孔分布均为散孔材，具较高的单孔率；导管分子穿孔板兼有单穿孔和梯状穿孔2种或者仅具有单穿孔；导管间纹孔式为互列；导管－射线间纹孔式类型丰富，主要为刻痕状和大圆状。木射线有单列和多列射线2种类型，单列射线稀少、短，多列射线数量多；射线组织主要为异形Ⅲ和异形Ⅱ；轴向薄壁组织以傍管状为主，少数有带状或轮界状。油细胞和粘液细胞普遍存在于射线薄壁细胞或轴向薄壁细胞中。木纤维由韧性纤维和纤维管胞组成，部分树种具分隔纤维。

The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.

刺鳅，属鲈形目、刺鳅科(Perciformes，Mastacembelidae)，是广泛分布于中国南方的小型淡水鱼类。1998年，我室通过核型分析，首次发现该物种具有明显分化的异形性染色体，其性别决定类型为XX／XY型。1999年，本室通过染色体显带、精母细胞联会复合体观察，再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体，两者不仅已经出现结构异染色质分布上的不同，同时在外部形态上也存在明显差异，识别特征鲜明，在光镜观察下无需显带即能清晰辨认性染色体。
