Glandular trichomes on the surface of Solanaceae species produce acyl sugars that are species-, and cultivar-specific. Acyl sugars are known to possess insecticidal, antibiotic, and hormone-like properties, and as such have great potential as a class of naturally occurring pesticides and antibiotics. The objective of this work was to analyze the acyl composition of acyl sugars in the leaf trichome exudate from selected Nicotiana species and to follow the inheritance of acyl content in their hybrids. Trichome exudates were collected, and the acyl profiles of acyl sugars were identified via GC–MS. The variations in acyl group inheritance in the hybrids (a single parent resemblance, missing, complementary, and novel groups) matched the patterns described in the literature for a variety of secondary metabolites. However, we did not find a complementation of major parental acyl groups. Instead, in some hybrids we observed a dynamic change in the proportions of acyl groups, distinguishing the acyl group profiles as novel. We observed paternal (i.e. N. tabacum cv. Turkish Samsun × N. benthamiana hybrids) and maternal (i.e. N. tabacum cv. Samsun-nn × N. otophora) inheritance patterns, novel acyl profiles (N. excelsior hybrids), and missing acyl groups (N. excelsiana). Selective inheritance of some acyl groups in the hybrids of N. benthamiana (4- and 5-methylheptanoic isomers) or N. alata (octanoate) was found. Suggestions are given to explain certain patterns of inheritance. The data presented here contribute to the body of knowledge about the effect of interspecific hybridization on the secondary metabolites by including acylsugar acyl groups that have not been studied previously.

烟草属的选定种间杂种中酰基糖酰基的遗传模式。

茄科物种表面上的腺毛状体产生酰基糖,该酰基糖是物种特异性和品种特异性的。已知酰基糖具有杀虫,抗生素和类激素的特性,因此具有作为一类天然农药和抗生素的巨大潜力。这项工作的目的是分析所选烟草叶片毛状体渗出液中酰基糖的酰基组成并遵循其杂种中酰基含量的遗传。收集绒毛虫分泌液,并通过GC-MS鉴定酰基糖的酰基分布。杂种中酰基基团遗传的变化(单亲本相似,缺失,互补和新颖的基团)与文献中描述的各种次级代谢产物的模式相匹配。但是,我们没有发现主要的亲本酰基团的互补。取而代之的是,在某些杂种中,我们观察到了酰基比例的动态变化,从而将酰基轮廓区分为新颖的。我们观察到父本(即烟草的土耳其Samsun×  N. benthamiana杂种)和母体(即烟草的Samsun-nn×  N. otophora)。)的继承模式,新的酰基特征(N. excelsior杂种)和缺失的酰基(N. excelsiana)。在本氏猪笼草(4-和5-甲基庚酸异构体)或阿拉斯猪笼草(辛酸酯)的杂种中发现了一些酰基的选择性遗传。提出了一些建议来解释某些继承模式。本文提供的数据通过包含以前没有研究过的酰基糖酰基,有助于有关种间杂交对次生代谢产物的影响的知识体系。
