Abstract

Almond is one of the most important nut crops worldwide. In Italy, 96% of the national almond production is covered by the Southern regions. However, small resources of cultivated and wild trees are also found in central Italian regions like Abruzzo, Sardinia, and Marche. Exploratory missions throughout the Marche region revealed the presence of many local and uncharacterized almond genotypes. The aim of this study was to recover this germplasm and characterize it using molecular markers. The genetic analysis revealed a high genetic variation in Marche almond genotypes, which showed them to be genetically distinct from the Italian and international varieties. A great richness in private alleles was found in the Marche almond collection, supporting the uniqueness of this germplasm and the importance of this resource of genetic diversity for the development of conservation programs and the implementation of almond breeding activities.

意大利中部未开发的杏仁生物多样性：利用分子标记的遗传特征和保护策略。

杏仁是世界上最重要的坚果作物之一。在意大利，96%的杏仁产自南部地区。然而，在意大利中部地区，如阿布鲁佐、撒丁岛和马尔凯，也发现了少量的栽培和野生树木资源。整个马尔凯地区的探索任务揭示了许多当地和未表征的杏仁基因型的存在。本研究的目的是恢复该种质资源，并利用分子标记对其进行鉴定。遗传分析显示，马尔凯杏仁基因型的遗传变异很大，这表明它们在遗传上与意大利和国际品种不同。在马尔凯杏仁中发现了非常丰富的私人等位基因，支持了这一种质资源的独特性，以及这一遗传多样性资源对保护计划的制定和杏树育种活动的实施的重要性。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
