Abstract

Strawberry (Fragaria × ananassa) is an important horticultural crop and is highly nutritious and valuable. However, several molecular mechanisms on the biosynthesis and metabolism of aroma compounds and the regulatory network that governs aromas remain unknown. This study investigated the influence of different altitude ecotypes on the components of pulp aroma and volatile metabolites in strawberry hybrid F₁ and its parents. “Perilla alcohol” was found to be the major factor that regulated the aroma of strawberry pulp from plants at low altitudes, and “perilla alcohol, linalool, alpha-farnesene and E-2-hexenyl benzoate” were the major factors that regulated the aroma of strawberry pulp from plants at high altitudes. Furthermore, three key candidate genes were identified according to the criteria of |K.i| > 40 and |MM| > 0.90. This study will establish a theoretical foundation for the cultivation of novel varieties of strawberries characterized by superior quality and flavor.

期刊介绍： Food Research International serves as a rapid dissemination platform for significant and impactful research in food science, technology, engineering, and nutrition. The journal focuses on publishing novel, high-quality, and high-impact review papers, original research papers, and letters to the editors across various disciplines in the science and technology of food. Additionally, it follows a policy of publishing special issues on topical and emergent subjects in food research or related areas. Selected, peer-reviewed papers from scientific meetings, workshops, and conferences on the science, technology, and engineering of foods are also featured in special issues.
