“…In short, the moisture content is used to classify the dates as soft, semi‐dry, and dry cultivars (Espiard, 2002). The numbers of date palm cultivars are estimated to be around 3,000 to 5,000 round the globe but only 10% has commercial importance (Abul‐Soad et al., 2017). In addition, the number of top commercial cultivars is small since every date producing countries have few major exporting cultivars while most of the germplasm either consumed locally or used as a mixture of different cultivars to make different by‐products.…”

“…Date palm is traditionally found and cultivated in hot and dry areas of Southwest Asia and North Africa on large scale, while small population also found in dispersed areas of USA, South America, and Southern Europe due to the extension of military expeditions and missionary works first from Asia to Europe and then Europe to the new world (American continent). But, with the advancement of tissue culture technology, it enables date palm cultivation in some non‐dates producing regions including Thailand and Indonesia (Abul‐Soad, Jain, & Jatoi, 2017). It is ought to be originated in Mesopotamia or gulf region, while several other countries including Egypt and Pakistan are in the list claiming the date palm origin in their ancient civilizations (Zohary, Hopf, & Weiss, 2012).…”

Date palm counts among the oldest fruit crops of the world and is mainly cultivated for its highly nutritious fruits consumed as a staple food in many countries, especially in the Gulf region. Dates are enriched with numerous therapeutic bioactives and functional compounds such as phenolics, flavonols, carotenoids, minerals, and vitamins that not only provide an appreciable amount of energy required for the human body but also act as an effective therapeutic agent against several diseases. This review aimed to provide a deep insight into the nutritional as well as phytochemicals profile of date fruit and its seeds in order to explore their biological (anti‐cancer, anti‐diabetic, cardio‐protective, anti‐inflammatory properties), functional food, and nutra‐pharmaceutical attributes. Practical applications This review provides updated information regarding the date fruits and seeds phytochemicals composition together with highlighting dates potential as a natural therapeutic agent against several diseases. The study also urges the importance of consuming dates as a great package to live a healthy life due to the functional food and nutraceutical properties of this valuable fruit. The study also provides information first time as recommending dates to cope with the hidden hunger or micronutrient deficiency faced by the third world inhabitants. Hence, the review may further help the industry and researchers to explore the potential of dates for future medicinal and nutra‐pharmaceutical applications.

“…In addition to natural disasters, deforestation, industrialization, biotic and abiotic factors occurring under the influence of human population growth are resulting in yield losses. Therefore, agricultural sustainability could be provided by the conservation and improvement of crops (Abul‐Soad et al 2017). Analysis of the genetic diversity in these species will provide valuable data to contribute to conservation and management programmes as well as to improve the crops (Hamza et al 2012, Purayil et al 2018).…”

“…Molecular marker techniques have been successfully employed to determine polymorphism and to evaluate the genetic relationship between palm cultivars (Abul‐Soad et al 2017). Among them, the ISSR approach is reported as a reliable technology for the identification of Phoenix species, and for the accurate display of their genetic diversity (Karim et al 2010, Hamza et al 2012, Kareem et al 2016, Mirbahar et al 2016, Purayil et al 2018).…”

“…Phoenix dactylifera was also cultivated in the Aegean and Mediterranean areas of Turkey (Esener 1999, Hazır and Büyüköztürk 2013, Boydak 2019). Although the exact origin of the date palm is not known, their seeds, found in ancient sites by archaeobotanical studies, suggest that the date palm may have more than one origin: Mesopotamia region, Nile Valley, Arabian Peninsula and Pakistan (Nixon 1959, Wrigley 1995, Zohary and Hopf 2000, Abul‐Soad et al 2017). Phoenix theophrasti , also known as Cretan date palm, was first included in P. dactylifera and was only relatively recently described as a separate species, based on certain morphological traits by Greuter (1967).…”

Intraspecific and interspecific diversity between Phoenix theophrasti individuals (92 from Turkey and 70 from Crete, Greece) and P. dactylifera specimens (28 from Turkey) were investigated by inter-simple sequence repeat (ISSR) analysis. A total of 45 polymorphic fragments, 360-3454 bps long, were produced. Intraspecific diversity for P. dactylifera was 26.63% and similarities ranged between 0.5 and 1. In the constructed dendrogram, P. dactylifera specimens clustered together in the first main group, outside branches consisting of P. theophrasti samples that generated the second main group. The intraspecific diversity for Turkish P. theophrasti populations was found to be 18.60% and for Cretan populations 13.45%. Antalya-Kumluca-Karaöz samples were grouped outside the branches of the remaining P. theophrasti samples. All three Cretan populations formed their own, separate branch. Datça-Eksera Stream samples together with two Datça-Hurmalıbük specimens constituted a group excluding Datça-Hurmalıbük and Bodrum-Gölköy specimens. Five Bodrum-Gölköy genotypes were clustered separately. Gene flow (N m ) values among populations were estimated from 0.157 to 59.615. AMOVA analysis revealed the percentages of variance among and within Phoenix populations: 73% and 27%, respectively. The first three principal coordinate components accounted for 37.60, 29.32 and 20.04%, respectively, thus the total variance obtained from the first three principal coordinate components was 86.96%. A positive correlation between geographic and genetic distances of populations was detected by Mantel tests (Rx,y = 0.44, p = 0.04). The populations were classified into four clusters by STRUCTURE analysis, supported the PCoA data. To conclude, ISSR results support that P. dactylifera and P. theophrasti are different species. Moreover, the findings not only revealed relationships between natural Phoenix theophrasti populations but also supported the identification of the P. theophrasti individuals that are phenotypically differentiated in the divided Bodrum-Gölköy population (P. theophrasti subsp. golkoyana).ISSR genotyping of Phoenix theophrasti natural populations in Turkey and Crete (Greece) and P. dactylifera
