laticifer
解釋
產乳菌絲-
The results showed that the prime symptoms of the tpd include laticifer necrosis and cambium - like meristem formation that occurs around the necrotic laticifer in the inner bark
結果表明該病的基本癥狀是在樹皮內層發生乳管壞死和在壞死的乳管周圍產生形成層狀分生組織。 -
This result showed that gus was transiently expressed in the foliage, and they were of laticifer - expression
因此認為gus基因在葉片成功的實現瞬時表達，而且具有乳管表達活性。 -
Thus it ' s necessary to recombine the heterogeneous gene with the promoter of laticifer - expression gene, and then the heterogeneous gene will express in laticifers
為此需將外源基因與乳管表達基因的啟動子連接，令其在乳管中表達。 -
To identify its laticifer - expression character, two transient - expression vectors ( pirl, pbir2 ) were constructed. in the transient - expression vector, ref promoter sequence replaced camv35s promoter of pbi121
為驗證其乳管表達活性，通過取代pbi121中間表達載體上的camv35s啟動子，構建了兩個含gus基因的瞬時表達載體pbir1 、 pbir2 。 -
Rubber tree ( hevea brasiliensis ) is an important economic woody - crop in tropical areas. its latex is the unique source of crude rubber used in current industry. because of its special and important use, the rubber tree has been extensively planted in tropical areas. increase production is always the main target in rubber tree cultivation. since the ethrel was applied in increasing latex production in 1968 for the first time as a chemical stimulant, not only the latex production had been increased largely, but also a new set of rubber tapping system had been established, leading to a series of economic benefit. owing to ethrel " s extensive application, its side effects had been found more and more obviously, such as tapping dry, speeding up senescence, shortening the life span of rubber tree etc. in order to overcome the side effects and increase production more availably, for a long time, people had carried out lots of research work on cell level, membrane level, physiology and biochemistry of laticifer contents. but the mech anism why ethrel increased latex production was not yet understood completely. this study had cloned the ethylene receptor gene ( efrl ) from rubber tree, and researched the relationship between etrl expression in laticifers and ethrel stimulation on transcription level and protein translation level. the results were as follows : 1
但是，由於乙烯利應用的普及，乙烯利刺激割膠引起橡膠樹發生死皮病及加速膠樹衰老，縮短膠樹壽命等副作用也越來越明顯。為了克服這些副作用，使乙烯利能更有效地刺激增產，長期以來，人們在細胞水平、膜水平和乳管細胞內含物的生理生化層面上進行了大量的研究，但仍未完全了解乙烯對膠樹的作用機制。本研究從分子水平入手，克隆橡膠樹的乙烯受體基因（ etr1 ） ，並在轉錄水平和蛋白質翻譯水平上研究etr1基因在乳管細胞中的表達及與乙烯刺激的關系，取得了以下結果： 1
