Investigating crop origins is a priority to understand the evolution of plants under domestication, develop strategies for conservation and valorization of agrobiodiversity and acquire fundamental knowledge for cultivar improvement. The date palm (Phoenix dactylifera L.) belongs to the genus Phoenix, which comprises 14 species morphologically very close, sometimes hardly distinguishable. It has...

Understanding the driving forces and molecular processes underlying dioecy and sex chromosome evolution, leading from hermaphroditism to the occurrence of male and female individuals, is of considerable interest in fundamental and applied research. The genus Phoenix, belonging to the Arecaceae family, consists uniquely of dioecious species. Phylogenetic data suggest that the genus Phoenix has d...

The anamorphic fungus genus Periconia is worldwide in distribution and causes foliar disease on plants mostly in tropical and subtropical regions. This study presents the description and illustration of P. palmivora discovered on leaves of Phoenix dactylifera (Palmae/Arecaceae) from Terai forest region of Uttar Pradesh, India. The taxonomic determination was based on morphological characteristi...

Four palm species, previously unknown hosts for Rhynchophorus palmarum L. (Coleoptera: Curculionidae), were killed by this invasive weevil in Balboa Park, San Diego County, California, USA. The 4 new species recorded as reproductive R. the first time are Brahea edulis, Jubaea chilensis, Phoenix reclinata, and Sabal bermudana (all Arecaceae). canariensis Chabaud (Arecaceae) is most highly attack...

As for the whole world, Coronavirus crisis generated in Morocco a significant shock on supply as well demand, putting several activities slow motion. Like different economic sectors, date palm (Phoenix dactylifera L) sector which presents real natural and cultural wealth of country has suffered drastically confinement period. This study targets some groves Draa-Tafilalet region provinces Errach...

The ameliorative activity of aqueous extract of the flesh of dates (Phoenix dactylifera L.) and ascorbic acid on thioacetamide-induced hepatotoxicity was studied in rats. Sixty male rats were divided into six equal groups of 10. Two groups were controls, one treated with thioacetamide and one with only distilled water. Two groups received extract of flesh Phoenix dactylifera and intraperitoneal...
