蛋白质是构成生命系统的基本元件之一,是大部分生物学功能的执行者。蛋白质丰度与其生物学功能息息相关,其丰度受基因表达过程中各环节严格精密的调控。其中,蛋白质丰度与其相应mRNA丰度存在较强的相关性,蛋白质丰度差异的40%可由mRNA丰度来解释。茉莉酸信号途径调节巴西橡胶树中的天然橡胶生物合成,但相关基因彼此间的表达丰度差异尚待阐明。该文比较了S/2D d3割胶制度下,15个橡胶生物合成调控相关基因COI1、JAZ1、JAZ2、JAZ3、MYC1、MYC2、MYC3、MYC4、MYC5、GAPDH、HMGR1、SRPP、REF、HRT1、HRT2以及2个常用内参基因18S、ACTIN1在10个橡胶树种质胶乳中的表达丰度差异;将ACTIN1的表达丰度设定为1,以此为标准计算出样品中其他基因的表达丰度。结果表明:相同个体中不同基因的转录丰度差异明显,不同个体中相同基因集的丰度大小排序存在一定差异;同一基因在不同个体中的转录丰度差异明显,这16个基因的最大丰度分别是最低丰度的9.43、6.04、10.02、12.29、18.82、9.22、38.46、112.83、121.36、15.34、19.09、13.54、10.05、19.80、24.83、11.82倍,他们的变异系数分别为73.05%、55.19%、69.09%、67.37%、66.59%、53.87%、83.25%、122.02%、166.34%、59.89%、70.59%、75.67%、74.20%、68.34%、84.23%、78.59%;总的来说,在群体水平上,16个基因的转录丰度从高到低依次为18S SRPPHMGR1REFMYC2/HRT1COI1MYC1/MYC4GAPDH/JAZ1/MYC5JAZ2HRT2/MYC3/JAZ3,他们的群体平均丰度依次为ACTIN1的28 382.26、43.64、11.39、7.16、5.47、5.10、1.07、0.75、0.74、0.45、0.42、0.33、0.12、0.06、0.06、0.04倍。值得注意的是,无论在个体水平还是群体水平上,18S的丰度毫无疑问是最大的,在mRNA中,SRPP的丰度最大,JAZ1大于JAZ2和JAZ3,MYC2大于MYC1、MYC3、MYC4、MYC5,HRT1大于HRT2。综上结果表明,结构基因和功能基因的丰度高于调控基因。在基因相对表达分析中,常对目的基因和内参基因作均一化处理,从而掩盖了不同基因间的真实丰度差异,因此,在基因表达分析中,既要关注基因的相对表达量,也要关注基因间的丰度差异,这有助于更全面地理解基因的功能。  相似文献

Socioeconomic Value and Growth of Naturalized Musa balbisiana L. A. Colla Leaves in Honduras. Musa balbisiana (Musaceae) is a seed–producing diploid banana indigenous to Southeast Asia. After it was introduced to Honduras it became naturalized in nearby second–growth areas of the north coast. Local residents were quick to recognize the socioeconomic value of these wild banana leaves as a wrap for traditional nacatamales. To estimate the monetary value and to provide preliminary data on sustainable harvest of these leaves, interviews and field research were undertaken in 2009. From July to September of that year, each of 38 harvesters averaged a weekly sale of 4,400 cut, de–veined, and blanched M. balbisiana leaves. This weekly harvest sold for Lempiras (Lps.) 550.00 or ca. U.S. 30.00 to truckers, who transported them to major markets. The number of leaves produced in three months was estimated by two techniques: 1) The traditional cut of the entire pseudostem and 2) a careful cut to only remove useful leaves. The number of useful leaves cut at the onset of the study and three months later was 11 and 13 for techniques 1 and 2, respectively. This difference was not significant, but the more careful method did yield significantly wider, longer, and a greater number of total leaves (useful plus immature). This is the first field study to estimate leaf production by naturalized < i > M. balbisiana < /i > plants in Honduras. All leaves are currently harvested from wild populations and no sustainable management plans exist. The socioeconomic value and cultural use of < i > M. balbisiana < /i > leaves in Honduras is an example of an exotic species that has important socioeconomic benefits. This naturalized < i > Musa < /i > appearsM. balbisiana plants in Honduras. All leaves are currently harvested from wild populations and no sustainable management plans exist. The socioeconomic value and cultural use of M. balbisiana leaves in Honduras is an example of an exotic species that has important socioeconomic benefits. This naturalized Musa appears to have few of the negative impacts typically attributed to exotic plants.  相似文献

Background  

Coffee is an important crop and is crucial to the economy of many developing countries, generating around US70 billion per year. There are 115 species in the < i > Coffea < /i > genus, but only two, < i > C. arabica < /i > and < i > C. canephora < /i > , are commercially cultivated. Coffee plants are attacked by many pathogens and insect-pests, which affect not only the production of coffee but also its grain quality, reducing the commercial value of the product. The main insect-pest, the coffee berry borer ( < i > Hypotheneumus hampei < /i > ), is responsible for worldwide annual losses of around US70 billion per year. There are 115 species in the Coffea genus, but only two, C. arabica and C. canephora, are commercially cultivated. Coffee plants are attacked by many pathogens and insect-pests, which affect not only the production of coffee but also its grain quality, reducing the commercial value of the product. The main insect-pest, the coffee berry borer (Hypotheneumus hampei), is responsible for worldwide annual losses of around US500 million. The coffee berry borer exclusively damages the coffee berries, and it is mainly controlled by organochlorine insecticides that are both toxic and carcinogenic. Unfortunately, natural resistance in the genus Coffea to H. hampei has not been documented. To overcome these problems, biotechnological strategies can be used to introduce an α-amylase inhibitor gene (α-AI1), which confers resistance against the coffee berry borer insect-pest, into C. arabica plants.  相似文献

Vårdal, H., Bjørlo, A. & Sæther, O. A. (2002). Afrotropical Polypedilum subgenus Tripodura, with a review of the subgenus (Diptera: Chironomidae). —Zoologica Scripta, 31, 331–402. A subgeneric diagnosis for all stages of the subgenus Tripodura Townes, 1 945 of the genus Polypedilum Kieffer, 1 912 is given. Nine new Afrotropical species of Tripodura are described: P.(T.)chelum Vårdal sp. n., P.(T.)amplificatus Bjørlo sp. n., P.(T.)patulum Bjørlo sp. n., P.(T.)spinalveum Vårdal sp. n., P.(T.)ewei Bjørlo sp. n., P.(T.)ogoouense Bjørlo sp. n., P.(T.)akani Bjørlo sp. n., P.(T.)dagombae Bjørlo sp. n., and P.(T.)amputatum Bjørlo sp. n.; all as male imagines only. P.(T.)alboguttatum Kieffer, P.(T.)albosignatum Kieffer, P.(T.)tropicum Kieffer, P.(T.)pruina Freeman, P.(T.)quinqueguttatum Kieffer, P.(T.) aegyptium Kieffer, P.(T.) tridens Freeman, P.(T.)allansoni Freeman, P.(T.)longicrus Kieffer, P.(T.)annulatipes Kieffer and P.(T.)abyssiniae Kieffer are re‐described as male and female imagines, while P.(T.)majiis Lehmann, P.(T.)subovatum Freeman, P.(T.)griseoguttatum Kieffer, P.(T.)aferum Lehmann and P.(T.)kijabense Freeman are re‐described as male imagines only. Keys to the male and the known female imagines of the 30 Afrotropical species in the subgenus are presented. A phylogenetic analysis based on all available information on Tripodura from all over the world (135 species) is presented and discussed. The monophyly of the subgenus Tripodura is confirmed. The subgenus can be divided into 20 groups with the acifer group forming the sister group of two larger assemblages of groups in the order acifer (titicacae (ginzansecundum ((aferum (ewei (malickianum (floridense (halterale, pullum)))))) (subovatum (labeculosum ((parascalaenum (allansoni (apfelbecki (udominatum, parvum))))) ((((alboguttatum, aegyptium) quinqueguttatum) annulatipes)). Only in the titicacae, halterale, pullum and apfelbecki groups are the larvae of more than one species described, while one larva is known in each of the subovatum, parascalaenum, aegyptium and quinqueguttatum groups. Three or more pupae are known only from the halterale, pullum, apfelbecki and aegyptium groups. Thus, the tentative nature of the group divisions is obvious. Geographical co‐evolutionary analyses (Brooks parsimony analyses) of the subgenus as a whole and of the major groups are performed and the areas most likely to be part of the original areas estimated. Most probably, eastern South America and Africa were part of the ancestral area. There are multiple sister‐group relationships and generalized tracks between South and East Asia and Africa, between Africa and the Palaearctic region, between South and East Asia, between tropical Brazil and Africa, between East Asia and North America across a former Beringian land bridge, and between the Indo‐West Pacific region and New Zealand, but no evidence for transantarctic relationships.  相似文献

American minks with different genotypes containing the Aleutian coat color allele in the homozygous state, including the single recessive Aleutian (a/a); double recessive sapphire (a/a p/p) and lavender (m/m a/a); triple recessive violet (m/m a/a p/p); and dominant-recessive cross sapphire (S/+ a/a p/p), sapphire leopard (S K /+ a/a p/p), and shadow sapphire (S H /+ a/a p/p) minks, as well as American minks without the Aleutian allele, including the standard (+/+); single recessive silver-blue (p/p) and hedlund-white (h/h); double recessive pearl (k/k p/p), Finnish topaz (t S /t S b/b); incompletely dominant royal silver (S R /+), standard leopard (S K /+), and black crystal (C R /+); and dominant-recessive snowy topaz (C R /+ t S /t S b/b) and Kujtezhyspotted (S K /+ b/b) minks have been studied. Homozygosity for the a allele has been found to disturb the subcellular structure of leukocyte, namely the formation of abnormally large granules.  相似文献
