研究组织特异表达基因对揭示植物生长发育机制具有重要的意义。通过生物信息学、RT-PCR及荧光定量PCR方法鉴定了2个水稻特异表达基因,即Os01g18840叶特异和Os01g28500茎叶颖特异表达基因。通过检测它们在PEG、NaCl、ABA及暗处理下的表达情况,发现在各种胁迫处理下,Os01g18840基因的表达受到抑制,Os01g28500基因的表达受到诱导。进一步分析它们的基因及蛋白结构特点,发现Os01g18840蛋白含有1个卷曲螺旋结构域,是1个中间纤维蛋白;Os01g28500蛋白含有1个SCP类似结构域,是与病原反应相关的蛋白。另外,对它们上游启动子区的顺式元件进行分析,结果表明它们都含有大量的与叶片、叶肉细胞或绿色组织中表达相关的顺式作用元件。  相似文献

The protein composition of the egg development in the high royal jelly producing bees (Apis mellifera L.) was investigated. This pioneer study was to separate and quantify the proteins in the egg of the high royal jelly producing worker bees (Apis mellifera L.) by using two-dimensional gel electrophoresis along with their three-day development. The results showed that 160, 195, and 176 proteins, with a wide range of molecular weight (17-80 KDa) and relatively narrow scope of pI (4. 00-8.40) could be detected on day 1, day 2, and day 3, respectively, during the developmental process of the egg. Meanwhile 44 protein spots were constantly detected along with the egg development. Among them 36% were in the uptrend along with the egg development, 14% were in the downtrend, and 39% were of the largest expressed volume on day 2. In addition, the specific proteins were expressed on day 1, day 2, and day 3 (89, 77, and 80, respectively). Besides the coexistent and specific proteins, 24 proteins were expressed on day 1 and day 2, but silenced on day 3, 49 proteins were expressed on day 2 and day 3, but silenced on day 1, only 3 proteins were expressed on day 1 and day 3, but silenced on day 2. The result indicates that egg development is a sequential and complex gene controlled process, where the eggs of day 2 express the most active proteins. The coexistent proteins suggest that it is conservative and indispensable for this event. These specific proteins suggest that the different developmental stage needs specific proteins to regulate it.  相似文献

This study is to compare the protein composition of the high royal jelly producing bee (A. m. ligustica) with that of Carniolian bee (A. m. carnica) during their worker larval developmental stage. The experiment was carried out by two- dimensional gel electrophoresis. The results showed that significant higher numbers of total proteins (283) were detected in larvae of high royal jelly producing bees (Jelly bee) than those of Carniolian bees (152) on 2-d-old larvae. Among them, 110 proteins were presented on both strains of bee larvae, whereas 173 proteins were specific to larvae of Jelly bees, and 42 proteins were exclusive to Carniolian larvae. However, on the 4th d, a significant higher number of total proteins (290) were detected in larvae of Jelly bees than those of Carniolian bees (240), 163 proteins resolved to both bee larvae, and 127 proteins were specific to Jelly bees and 77 proteins to Camiolian bees. Until the 6th d, also a significant higher number of total proteins (236) were detected in larvae of Jelly bees than those of Carniolian bees (180), 132 proteins were constantly expressed in two bee larvae, whereas 104 and 48 proteins are unique to Jelly bee and Carniolian bee larvae, respectively. We tentatively concluded that the metabolic rate and gene expression of Jelly bees larvae is higher than those of Carniolian bees based proteins detected as total proteins and proteins specific to each stage of two strains of bee larvae. Proteins constantly expressed on 3 stages of larval development with some significant differences between two bee strains, and proteins unique to each stage expressed differences in term of quality and quantity, indicating that larval development needed house keeping and specific proteins to regulate its growth at different development phage, but the expression mold is different between two strains of larval development.  相似文献

蜜蜂(Apis mellifera L.)幼虫级型分化差异蛋白质组分析   总被引:3,自引:1,他引:2  
【目的】对蜜蜂(Apis mellifera L.)蜂王与工蜂级型分化期的蛋白质组进行比较,以探明蜂王和工蜂在级型分化时期蛋白质表达调控方面的异同。【方法】采用双向电泳建立蜂王和工蜂级型分化期蛋白质组表达 谱,获得图谱中蛋白质表达的数量、表达量、等电点和分子量等信息,然后进行比较蛋白质组研究。【结果】在幼虫3日龄,蜂王表达288个蛋白质,工蜂表达259个蛋白质,2种级型蜂共有蛋白质为156个,其中25个蛋白质在蜂王中的表达量显著大于(P<0.05)工蜂,34个蛋白质工蜂表达量显著大于(P<0.05)蜂王,而蜂王和工蜂的特异蛋白质分别为132个和103个;到幼虫5日龄时,蜂王表达274个蛋白质,工蜂为236个,这2种级型蜂共有蛋白质点为95个,其中蜂王15个蛋白质的表达量显著大于(P<0.05)工蜂,工蜂26个蛋白质的表达量显著大于(P<0.05)蜂王,而蜂王特异蛋白质点为179个,工蜂特异蛋白质点为141个;到蛹11日龄时,蜂王蛋白质组有311个蛋白质点,而工蜂则有278个蛋白质点,2种蜂共有蛋白质点为194个,其中蜂王45个蛋白质的表达量显著大于(P<0.05)工蜂,工蜂35个蛋白质的表达量显著大于(P<0.05)蜂王,而蜂王的特异蛋白质点为117个,工蜂特异蛋白质点为84个。【结论】在蜜蜂3日龄、5日龄、11日龄时,蜂王和工蜂的蛋白质表达谱存在显著差异,蜂王表达的蛋白质总数和特有蛋白质数都较工蜂多,说明蜂王幼虫的基因表达和代谢比工蜂幼虫更加旺盛。2种级型蜂发育中所表达的共有蛋白质可能是它们发育所必须的管家蛋白质,但级型间部分共有蛋白质的表达模式存在较大差异,在3个日龄中蜂王和工蜂中所表达的特异蛋白质表明在级型分化中,不同级型需要不同的蛋白质来调节各自的发育。这些特异蛋白质是否是级型发育相关的功能蛋白质,还有待进一步的研究。  相似文献
