1987年，Bapat等用桑树腋芽制成胶囊在体外繁殖成功，1992年，Machii用桑树冬芽中的幼叶诱导不定芽成功并用不定芽制作人工种子，但仅可萌发和长出新梢，还不能生根和转株.如果用体细胞胚制作人工种子，它的性能与天然种子更接近，繁殖系数也更高.桑树是木本植物，迄今体细胞胚的诱导还未成功.为此，笔者依据木本植物的特点，参考前人的经验，对桑树体细胞胚的诱导进行了研究，同时利用体细胞胚由来的小芽，进行了制作人工种子的探索，现将结果报道如下：...

Gentisate 1,2-dioxygenase (GDO, EC1.14.13) from Klebsiella pneumoniae M5a1 successfully converted gentisate to maleylpyruvate. This biotransformation was performed by using genetically engineered E. coli strain carrying a gene encoding gentisate 1,2-dioxygenase, and the maleylpyruvate synthesized by...

Polyclonal anti-serum of cholinesterase with dilution ratio of 1∶8 000 was obtained by immunizing BALB/c mice with purified cholinesterase (ChE) from Daphnia magna. An indirect and non-competitive enzyme-linked immunosorbent assay (ELISA), which used mice anti-Daphnia ChE as antibodies to react with...

Pseudomonas putida ZWL73, which completely degrades 4-chloronitrobenzene (4-CNB), can grow on the media with 3-hydroxybenzoate (3-HBA) as a sole carbon source and energy source. During the course of the degradation of 3-HBA, gentisate was produced as an intermediate. Through spectrophotometric analy...

Because of the difficulty to disrupt the yeast cell walls, and insolubility of β-D-glucan, the mensuration way for detecting β-D-glucan was a difficult problem. Firstly, vortex-mini-bead disruption way was used to broke the yeast cell walls and the ratio of broken yeast cells reached 95.28%; Secondl...

This paper presented a method for calculating quantity of available surface water based on evaluation of other presently usable methods. Difference obtained by subtracting amount of unavailable surface water from that of total surface water corresponds to the available portion. Unavailable water is...

Pseudomonas sp. strain ZWL73 grows on 4-chloronitrobenzene (4CNB) as a sole carbon and energy and its ability in degradation of 4CNB is plasmid-encoded. This strain and its plasmid transcon-jugant ZP8 (Psudomonas putida PaW340 harboring the 4CNB degradative plasmid) were tested in a chemotaxis assay...

High-oleic acid peanut oil (HOPO) and extra-virgin olive oil (EVOO) have been reported previously to have an attenuating effect on metabolic syndrome (MS). This study aimed to evaluate the metabolic effect of HOPO and EVOO supplementation in attenuating MS and the role of gut microbiota in regulatin...

Maize (Zea mays L.) is an economically vital grain crop that is cultivated worldwide. In 2011, a maize foliar disease was detected in Lingtai and Lintao counties in Gansu Province, China. The characteristic signs and symptoms of this disease include irregular chlorotic lesions on the tips and edges...

Small—but finite—fluid inertia can be leveraged to generate steady flows out of liquid vibrations around an immersed interface. In engineering, external high-frequency drivers (10^{2}–10^{5}Hz) allow this inertial rectification phenomenon, known as viscous streaming, to be employed in micron-scale d...
