花挥发性苯丙素和苯类化合物（VPBs）具有重要的生态功能和潜在的经济应用价值。关于多因子整合如何调控花vpb的形成和释放，我们知之甚少。以矮牵牛（Petuniax hybrida cv.）为研究对象，研究了内源生物钟、光照和温度等多种因素对花中主要挥发物VPBs形成和释放的影响。米切尔二倍体。内源性生物钟被认为是调控VPBs节律性发射和VPBs上游生物合成途径结构基因表达的最重要因素，但不影响下游途径结构基因和VPBs相关调控因子的表达水平。与光相比，温度是影响vpb发射的一个更恒定的因素。提高温度可以在短时间内抑制VPBs的发射。这些信息将有助于我们了解植物挥发物的释放机制。(C) 2016 Elsevier Masson SAS。版权所有。
Floral volatile phenylpropanoids and benzenoids (VPBs) play important ecological functions and have potential economic applications. Little is known about how multi-factors in integration regulate the formation and emission of floral VPBs. In the present study, we investigated effects of multi factors including endogenous circadian clock, light, and temperature on the formation and emission of VPBs, which are major volatiles in flowers of Petuniax hybrida cv. 'Mitchell Diploid'. Endogenous circadian clock was proposed as the most important factor regulating rhythmic emission of VPBs and expressions of structural genes involved in the upstream biosynthetic pathway of VPBs, but did not affect expression levels of structural genes involved in the downstream pathway and VPBs-related regulators. In contrast to light, temperature was a more constant factor affecting emission of VPBs. VPBs emission could be inhibited within a short time by increasing temperature. The information will contribute to our understanding of emission mechanism of floral volatiles. (C) 2016 Elsevier Masson SAS. All rights reserved.
