Abstract

This study was conducted to investigate the potential use of arbuscular mycorrhizal fungi (AMF), Rhizophagus irregularis, as an innovative cultivation procedure to improve the production and quality of two medicinal plants, pennyroyal (Mentha pulegium), and parsley (Petroselinum hortense). We elucidated the impact of AMF on soil properties and growth and metabolic profiling of pennyroyal and parsley. AMF treatment improved the availability of essential elements and phenols in the rhizospheric soil. Plant biomass production and photosynthetic rate were improved. We also recorded improved primary and secondary metabolism, where the levels of most of the detected soluble and insoluble sugars, organic acids, essential (isoleucine and valine), and non-essential (glutamine, alanine, and cysteine) amino acids, fatty acids (especially unsaturated fatty acids), phenolic acids, and flavonoids were increased. Overall, this study supports the use of AMF in the artificial cultivation, as an alternative to the chemical fertilizers, for the production of high-quality medicinal plants with enhanced levels of bioactive compounds.

丛枝菌根引起整体代谢变化，并改善戊二醛和香菜的营养和健康益处

摘要

进行这项研究的目的是探讨丛枝菌根真菌（AMF），不规则根瘤菌（Rhizophagusregis）的潜在用途，作为一种创新的种植程序，以提高两种药用植物，即戊香（Mentha pulegium）和欧芹（Petroselinum hortense）的产量和质量。）。我们阐明了AMF对土壤性质以及戊二醛和欧芹生长和代谢谱的影响。AMF处理提高了根际土壤中必需元素和酚的利用率。植物生物量产量和光合速率得到改善。我们还记录了一级和二级代谢的改善情况，其中检测到的大多数可溶性和不溶性糖，有机酸，必需的（异亮氨酸和缬氨酸）和非必需的（谷氨酰胺，丙氨酸和半胱氨酸）氨基酸，脂肪酸（尤其是不饱和脂肪酸），酚酸和类黄酮增加。总的来说，这项研究支持在人造栽培中使用AMF作为化学肥料的替代品，以生产具有增强的生物活性化合物含量的高质量药用植物。
