Abstract

ABSTRACT Lavandula angustifolia Mill. or true lavender is an emblematic plant from dry and calcareous hills of the south of France. Lavender essential oils obtained from inflorescences harvested at bloom stage are mainly composed of monoterpenes and few sesquiterpenes. The characteristic lavender smell is due to linalool and linalyl acetate that represent more than half of the emitted volatile organic compound (VOC) quantity. These monoterpenoids are derived from plastidial pathway precursors. The regulation of this pathway in lavender is mainly managed by the successive expression of two DXS during flower development. In the light of 10 years of published data on lavender, it appears that biochemical pathways of main terpenes are mostly depicted. Several transcriptomic libraries are available and a genome at chromosome scale has been assembled and molecular markers developed. The diversity of lavender terpenes and their biosynthesis are reviewed with additional original data regarding the anatomical glandular structures and expression of genes involved in IPP biosynthesis.

薰衣草。芳香药用植物挥发性有机物的合成、进化及生态功能研究

摘要薰衣草。真正的薰衣草是一种生长在法国南部干燥多钙质山丘上的标志性植物。薰衣草精油主要由单萜类和少量倍半萜类组成。薰衣草特有的气味是由于芳樟醇和醋酸芳樟醇占挥发性有机化合物(VOC)排放量的一半以上。这些单萜类化合物来源于质体途径的前体。在薰衣草中，这一通路的调控主要通过两个DXS在花发育过程中的连续表达来实现。根据10年来发表的关于薰衣草的数据，似乎主要萜烯的生化途径主要被描述。一些转录组文库是可用的，染色体尺度的基因组已经组装和分子标记开发。本文综述了薰衣草萜类化合物的多样性及其生物合成，并对其解剖腺结构和参与IPP生物合成的基因表达等方面的原始数据进行了综述。

期刊介绍： Botany Letters is an international scientific journal, published by the French Botanical Society (Société botanique de France) in partnership with Taylor & Francis. Botany Letters replaces Acta Botanica Gallica, which was created in 1993, building on over a century of renowned publications by the Société botanique de France.
