摘要：Plant-based bioproduction of insect sex pheromones has been proposed as an innovative strategy to increase the sustainability of pest control in ***,we describe the engineering of transgenic plants producing(Z)-11-hexadecenol(Z11-16OH)and(Z)-11-hexadecenyl acetate(Z11-16OAc),two main volatile components in many Lepidoptera sex pheromone *** assembled multigene DNA constructs encoding the pheromone biosynthetic pathway and stably transformed them into Nicotiana benthamiana *** constructs contained the Amyelois transitella AtrΔ11 desaturase gene,the Helicoverpa armigera fatty acyl reductase HarFAR gene,and the Euonymus alatus diacylglycerol acetyltransferase EaDAct gene in different *** the pheromone-producing plants showed dwarf phenotypes,the severity of which correlated with pheromone *** but one of the recovered lines produced high levels of Z11-16OH,but very low levels of Z11-16OAc,probably as a result of recurrent truncations at the level of the EaDAct *** one plant line(SxPv1.2)was recovered that harboured an intact pheromone pathway and which produced moderate levels of Z11-16OAc(11.8μg g^(-1) FW)and high levels of Z11-16OH(111.4μg g^(-1)).Z11-16OAc production was accompanied in SxPv1.2 by a partial recovery of the dwarf ***1.2 was used to estimate the rates of volatile pheromone release,which resulted in 8.48 ng g-1 FW per day for Z11-16OH and 9.44 ng g^(-1 )FW per day for *** results suggest that pheromone release acts as a limiting factor in pheromone biodispenser strategies and establish a roadmap for biotechnological improvements.
