20.500.12556/DiRROS-31098 Soil-origin effects on wild lupin seed traits and their potential for crop development This paper explores the effect of soil type at the site of origin on lupin seed phytochemistry. We examined wild populations of lupins originating from basaltic and calcareous soils and analyzed their seed morphology and phytochemical profiles, with a particular focus on secondary metabolites—namely quinolizidine alkaloids and ionomes. The two lupin species studied, Lupinus pilosus and L. palaestinus, are native to Israel and were collected from wild populations. The overarching goal of this study is to leverage this knowledge to facilitate the domestication of these crop wild relatives for food or feed applications. We sampled 30 populations of the two species across Israel, characterized their environments at the landscape scale, and integrated this data with quinolizidine alkaloid profiles obtained from the seeds. This approach enabled us to elucidate the biochemical and ecological contexts underlying alkaloid formation. This study reveals that L. pilosus and L. palaestinus can be distinguished based on their seed phytochemical profiles. We suggest that these distinguished profiles are related to their soil origin. Our results highlight the influence of pedological origin—basaltic vs calcareous soils on both quinolizidine alkaloid composition and ionomic profiles in wild lupins. These insights may ultimately support the development of novel crops, contribute to agricultural diversification, and enhance crop resilience. fitokemija kinolizidinski alkaloidi odpornost poljščin raznolikost kmetijstva divji sorodniki poljščin phytochemistry quinolizidine alkaloid crop resilience agricultural diversification crop wild relatives true false true Maximum Academic Press ZDA Angleški jezik Ni določen © 2026 by the author(s).
