Genome sequence of the date palm Phoenix dactylifera L
Date palm (Phoenix dactylifera L.) is a cultivated woody plant species with agricultural and economic importance. Here we report a genome assembly for an elite variety (Khalas), which is 605.4 Mb in size and covers >90% of the genome (~671 Mb) and >96% of its genes (~41,660 genes). Genomic sequence analysis demonstrates that P. dactylifera experienced a clear genome-wide duplication after eithe...
متن کاملRapid in vitro regeneration of date palm (Phoenix dactylifera L.) cv. Kheneizi using tender leaf explant
Somatic embryogenesis has been accomplished from tender leaf base explant of date palm (Phoenix dactylifera L.). Three to five mm long tender leaf base explants derived from the meristamatic region of 2-3 year old offshoots of date palm cv. Kheneizi were cultured on Murashige and Skoog (MS) basal medium supplemented with 10, 50, 100 and 150 mg l 2,4-dichlorophenoxy acetic acid (2,4-D) and incub...
متن کاملSocio-economic characterisation of date palm (Phoenix dactylifera L.) growers and date value chains in Pakistan
Increasing food production to feed its rapidly growing population is a major policy goal of Pakistan. The production of traditional staples such as rice (Oryza sativa L.) and bread wheat (Triticum aestivum L.) has been intensified in many regions, but not in remote, drought-ridden areas. In these arid, marginal environments dates and their by-products are an option to complement staples given t...
متن کاملIsolation of Pathogenic Bacillus circulans from Callus Cultures and Healthy Offshoots of Date Palm (Phoenix dactylifera L.).
Pure cultures of a gram-negative, rod-shaped bacterium, which produced endospores after 3 to 5 days on solid medium, were isolated exclusively from tissue cultures of the date palm Phoenix dactylifera L. Electron microscopic examination of thin sections of the bacteria revealed the bilayer membrane typical of gramnegative bacteria and confirmed the nature of the spores as true endospores. Bioch...
متن کاملA simplified Protocol to Induce Callogenesis in Protoplasts of Date Palm (Phoenix dactylifera L.) Cultivars
Background: In Algeria, date palm is currently confronted to the Bayoud disease. Biotechnological tools such as protoplasts fusion can appear as an alternative to ensure rapid multiplication and improvement of this species. Objectives: Callogenesis induction in protoplasts isolated from embryogenic callus of three date palm cultivars. Materials and Methods: Some factors influencing the isolatio...
