The date palm, Phoenix dactylifera, has been a cornerstone of Middle Eastern and North African agriculture for millennia. It was first domesticated in the Persian Gulf, its evolution appears to have influenced by gene flow from two wild relatives, P. theophrasti, currently restricted Crete Turkey, sylvestris, widespread Bangladesh West Himalayas. Genomes ancient palm seeds show that theophrasti dactylifera may occurred ∼2,200 years ago, but traces sylvestris could not be detected. We here integrate archeogenomics ∼2,100-year-old leaf Saqqara (Egypt), molecular-clock dating, coalescence approaches with population genomic tests, probe hybridization between closest relatives provide minimum maximum timestamps reticulated evolution. shares close genetic affinity populations, we find clear admixture both indicating had contributed genome 2,100 ago.

Ethnobotanical knowledge is indispensable for the conservation of global biological integrity, and could provide irreplaceable clues bioprospecting aiming at new food crops medicines. This biocultural diversity requires a comprehensive documentation such intellectual local levels. However, without systematically capturing data, those regional records are fragmented can hardly be used. In this study, we develop framework to assemble cross-cultural ethnobotanical genus level, including species’ their cultural importance, integrating traditional uses, revealing intercultural relationship data quantitatively. Using assembly, medicinal culinary values Lycium evaluated. Simultaneously, analysis highlights problems options systematic assembly.

Societal Impact Statement Digitized molecular data are vital to numerous aspects of scientific research and genetic resource use. The Convention on Biological Diversity currently refers this as “Digital Sequence Information” (DSI), a term not widely adopted by science lacking clear definition. There concerns over the access resources absence benefit sharing provider countries. Open DSI might exacerbate this, which is leading increasing policy interventions restricted DSI. We analyze current international debate proposed solutions provide case studies use producing tangible benefits for countries research, demonstrating importance open achieving conservation goals.
