摘要

大麻（Cannabis sativa L.）的花朵密布腺毛体，其中含有用于药用和娱乐目的的大麻树脂。高产的腺毛被称为 "生物工厂"。在本综述中，我们将利用这一比喻来重点介绍大麻细胞生物学、代谢组学和转录组学的最新进展。生物工厂由表皮长出的部分构建，这些部分分化成盾状腺毛头，由具有独特细胞结构的盘状分泌细胞组成。大麻素和萜类化合物产品储存在细胞外储存腔中。最后，多细胞柄将腺体头抬高到表皮之上，使大麻花呈现出霜冻般的外观。

Building a biofactory: Constructing glandular trichomes in Cannabis sativa

Flowers of Cannabis sativa L. are densely covered with glandular trichomes containing cannabis resin that is used for medicinal and recreational purposes. The highly productive glandular trichomes have been described as ‘biofactories.’ In this review, we use this analogy to highlight recent advances in cannabis cell biology, metabolomics, and transcriptomics. The biofactory is built by epidermal outgrowths that differentiate into peltate-like glandular trichome heads, consisting of a disc of interconnected secretory cells with unique cellular structures. Cannabinoid and terpenoid products are warehoused in the extracellular storage cavity. Finally, multicellular stalks raise the glandular heads above the epidermis, giving cannabis flower their frosty appearance.
