Here the authors examined the egg case silks from the orb web spider, Argiope amoena and Nephila clavata by the automatic amino acid analyzer, SEM, FTIR and electric single-fiber tensile apparatus with the goal of expanding our understanding of the relationship between the structure, mechanical performance and biological function of these unique biomaterials.

作者采用氨基酸自动分析仪、傅立叶转换红外光谱仪、扫描电镜和电子单纤强力仪对悦目金蛛和棒络新妇的卵袋丝进行了物理化学结构表征与力学性能的研究，结果表明两种蜘蛛卵袋均由微米级柱状腺丝、大壶状腺丝、亚微米级或纳米级葡萄状腺丝构成。

Samples of conchocelis and gametophytic baldes of both SF-1 and Y-6 (isolated from SF-1 line) lines had a unique allele on PC40 locus, indicating that it can be used as a marker to distinguish these two lines from the others.

在引物PC-40界定的遗传座位上，2个优良品系申福1号和优质6号（以申福1号为母本选育出来的品系）的丝状体和叶状体均出现了区别于其他品系的等位基因，显示对这2个优良品系进行SSR特异性标记是可能的。

In this paper the authors report on the biological characteristics of Al-sophila spinulosa Hook.

Results:(1) The conchosporangia of brown yellow mutant was smaller and mature time was 15 days later than the parents. Thallus grew slowly in early stage, but average daily growth rate reached (7.50±1.18) cm after blade length was over 60 cm.(2)The emerald conchocelis were easy to mature and had special developmental mode that the spherulocytes can directly develop into sporangial branchlets and conchosporangia without thick conchocelis stage. Emerald blades were low in RPE with just (6.4710±0.0184) mg/g dry mass. The thallus grew quickly, average daily growth rate reached (11.95±2.33) cm after blade length was over 60 cm.(3) The conchocelis filaments of breen mutant were thin and short. Thallus grew slowly and had low contents of three phycobiliprotenin and chlorophyl.

实验进行50d。结果：(1)褐黄色突变体藻蓝蛋白和别藻蓝蛋白含量低；孢子囊枝的细胞较小，且大量形成时间比亲本晚15d；幼苗培养初期日平均生长量仅为(1.22±0.28)cm，当叶片长到60cm左右时生长优势逐步凸显，日平均生长量可达(7.50±1.18)cm；(2)翠绿色丝状体容易成熟，发育方式特殊，营养藻丝不经过藻丝加粗阶段，直接由球形细胞发育成孢子囊枝和壳孢子囊；翠绿色叶状体藻红蛋白含量低，仅有(5.5130±1.0496)mg/g；叶状体生长快速，60cm长的藻体日平均生长量高达(11.95±2.33)cm；(3)褐绿色突变体藻蓝蛋白、别藻蓝蛋白和藻红蛋白这3种色素蛋白和叶绿素的含量均较低；藻丝细胞短且细，叶状体生长速度较慢。
