Arbuscular mycorrhizal fungi (AMF) are a promising tool to improve plant nutrient use efficiency (NUE) and tolerance against abiotic stresses. Moreover, AMF can potentially increase plant productivity and reduce the negative externalities of the agricultural sector. Our study aimed to elucidate whether AMF (containing Rhizoglomus irregulare and Funneliformis mosseae) could positively affect not only tomato growth and productivity but also the nutritional and nutraceutical quality of yellow-pigmented type (‘Giagiù’) and red-pigmented type (‘Lucariello’) tomatoes (Solanum lycopersicum L.). These cherry tomatoes are landraces of the Protected Designation of Origin (PDO) ‘Pomodorino del Piennolo del Vesuvio’ (PPV), one of the most typical agricultural products of the Campania region (Southern Italy). AMF rose fruit yield by increasing the number of fruits per plant (+49% and +29% in ‘Giagiù’ and ‘Lucariello’, respectively) but not of the fruit mean mass. AMF increased lycopene (+40%), total ascorbic acid (TAA; +41%), alanine (+162%), gamma-Aminobutyric acid (GABA; +101%) and branched-chain amino acids (BCAAs; +53%) in ‘Lucariello’. In ‘Giagiù’, AMF increased calcium (+63%), zinc (+45%), ASP (+70%), GABA (+53%) and the essential amino acids arginine (+58%) and lysine (+45%), also indicating a genotype-specific response. In both landraces, AMF improved nutrient uptake and biosynthesis of important molecules involved in the control the oxidative stress and cellular pH. In addition to the beneficial effects of human health, the molecules influenced by the AMF treatment are expected to extend the shelf life of tomato fruits, thus further promoting the useful agronomic application of AMF for premium tomatoes marketed fresh or in pendulums (‘piennoli’).

丛枝菌根真菌的生物刺激作用增强了'Piennolo del Vesuvio'樱桃番茄地方品种的生产力，功能和感官质量

丛枝菌根真菌（AMF）是提高植物养分利用效率（NUE）和抵抗非生物胁迫的有前途的工具。此外，AMF可以潜在地提高工厂的生产率并减少农业部门的负面外部性。我们的研究旨在阐明AMF（含有不规则根瘤菌和莫氏漏斗菌）是否不仅可以积极影响番茄的生长和生产力，而且还可以积极影响黄色色素型（'Giagiù'）和红色色素型（'Lucariello'）的营养和营养保健品质。 ）番茄（茄属植物lycopersicumL.）。这些樱桃番茄是原产地标记（PDO）'Pomodorino del Piennolo del Vesuvio'（PPV）的地方品种，它是Campania地区（意大利南部）最典型的农产品之一。AMF通过增加单株果实的数量来提高果实产量（“Giagiù”和“ Lucariello”分别为+ 49％和+ 29％），但不增加果实平均质量。AMF增加了番茄红素（+ 40％），总抗坏血酸（TAA; + 41％），丙氨酸（+162％），γ-氨基丁酸（GABA; + 101％）和支链氨基酸（BCAAs; + 53％） ）中的“ Lucariello”。在'Giagiù'中，AMF增加钙（+ 63％），锌（+45％），ASP（+70％），GABA（+ 53％）和必需氨基酸精氨酸（+ 58％）和赖氨酸（+45） ％），也表示特定的基因型反应。在两个地方，AMF改善了养分吸收和重要的生物合成，这些重要分子参与了氧化应激和细胞pH的控制。除了对人体健康有益之外，受AMF处理影响的分子有望延长番茄果实的货架期，从而进一步促进AMF在新鲜或摆锤市场上销售的优质番茄的有用农艺应用（“ piennoli”） 。
