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，由于乙烯利应用的普及，乙烯利刺激割胶引起橡胶树发生死皮病及加速胶树衰老，缩短胶树寿命等副作用也越来越明显。为了克服这些副作用，使乙烯利能更有效地刺激增产，长期以来，人们在细胞水平、膜水平和乳管细胞内含物的生理生化层面上进行了大量的研究，但仍未完全了解乙烯对胶树的作用机制。本研究从分子水平入手，克隆橡胶树的乙烯受体基因( etr1 ) ，并在转录水平和蛋白质翻译水平上研究etr1基因在乳管细胞中的表达及与乙烯刺激的关系，取得了以下结果： 1
