It is not know how cuticular waxes reach the epidermal surface from intracellular . the pathway most likely involves endoplastric reticulum , transport vesicles , substrate ligands , vesicle receptors and many other secretory factors 内质网、转运小泡、配体物质、膜泡受体和其它分泌因子可能参与了蜡质组成成分从细胞内到达表皮的运输过程。
Wax precursors are synthesized in the plastids and enlongated to very long acyl - coa chains as direct processors in er . once the very long acyl - coa chains are synthesized , they are converted to cuticular waxes by four different pathways 一般认为蜡质前体是在质体中合成并在内质网中延伸成特长链脂酰辅酶a ,合成的特长链脂酰辅酶a通过四种不同的途径转化成蜡质组成成分。
In aerial parts of the plant the outer wall of the epidermis is usually covered by a waxy cuticle that prevents desiccation , protects the underlying cells from mechanical damage , and increases protection against fungi , bacteria , etc 植物地上部分的表皮的最外层通常覆盖一层蜡质角质层,起保护作用以防止过渡蒸腾,并使下方的细胞免于机械损伤,同时增加对真菌、细菌等的防御能力。
Execution standard of manufacturing technique of wax : ( it is accord with sh / t0013 - 1999 petrochemical industry standard ) manufacturing technique of insect white wax : it is a kind of wax from tree privet or ash tree where insect wax excreted 微晶蜡的执行标准: (本产品符合sh / t0013 - 1999石油化工行业标准)虫白蜡的生产工艺流程:虫白蜡,是白蜡虫分泌在所寄生的女贞树或白蜡树枝上的蜡质。
This article discusses the composition of epicuticular wax of plant leaves , taxonomic utilization of morphological characters of wax , and the important function of cuticular wax for plants , such as protection from irradiation injury , loss of water , attack by microorganisms , parasitic insects 本文综述了植物叶表皮蜡质的成分、蜡质形态的分类学意义及蜡质对植物保水、防辐射和防病虫害等方面的作用。
Waxes form a continuous lipid membrance covering the epidermal cells of all aerial plant organs . it mainly comprised of lony - chain aliphatic compounds derived from very long chain fatty acids that are enlongedsfrom c16 - or c18 - long fatty acids in er by many fatty acid elongation ( fae ) complexs 陆生植物的气生器官的表皮覆盖着一层由蜡质形成的脂膜,它主要由长链疏水物质组成的,这些物质是特长链脂肪酸的衍生物。
These proteins are ubiquitous in the plant kingdom where they form a multiple genetic family . they have been suggested to be involved in dif ferent aspects of plant physiology and cell biology through their ability to bind and / or carry lipophilic compounds , including the formation of cutin by transporting the hydrophobic cutin monomers to the apoplast and the defence of plants against pathogens as antimicrobial agents and in flowering 此外nsltp在植物体内广泛存在并由一个基因家族编码,由于它能结合和转运脂类物质,因此推测它可能参与植物体内许多不同的生理过程,如转运蜡质的角质单体到表皮细胞外侧,作为抑菌蛋白抵抗病原菌的入侵以及花粉和柱头的识别等。
In order to utilize the by - products produced in the process of soybean oil to develop the series products with high - tech content and high affixture , the raw material classification , substance composing , product quality , function characteristics , extraction technology , applied field , the foreground of development and existent problems , were synthesized 摘要对植物性大豆蜡研发的原料分类、物质组成、产品质量、功能特点、提取技术、应用领域、发展前景及存在的问题进行了综合性表述,旨在综合利用大豆油脂加工中的副产物,开发高科技含量与高附加值的系列产品,开拓新的应用领域,为国家提供新的蜡质资源,并推进到国际商品市场。
