Novel subpopulations in date palm (Phoenix dactylifera) identified by population-wide organellar genome sequencing
2019
Background The date palm is one of the oldest cultivated fruit trees. The tree can withstand high temperatures and low water and the fruit can be stored dry offering nutrition across the year. The first region of cultivation is believed to be near modern day Iraq, however, where and if the date palm was domesticated is still a topic of debate. Recent studies of chloroplast and genomic DNA revealed two major subpopulations of cultivars centered in both the Eastern range of date palm cultivation including Arabian Peninsula, Iraq and parts of South Asia, and the Western range, including North Africa. Results To better understand the origins of date palm cultivation we sequenced and analyzed ov…
Changes in the bacterial community of Canary island date palm tissues attacked by Rhynchophorus ferrugineus (Coleoptera: Curculionidae).
2009
The red palm weevil (RPW), Rhynchophorus ferrugineus is a trunk tissue borer that has recently become the major pest of palms in the Mediterranean Basin. In Sicily the red palm weevil is strongly associated with the Canary island date palm, Phoenix canariensis Hortorum ex Chabaud, an ornamental palm with high economic value. RPW larvae consumes the trunk tender soft tissues, making galleries that present a chewed appearance with a characteristic fermented odour. Several aspects of the RPW’s biology still need to be investigated such as its gut bacterial community, and the agents of fermentation processes that occur in the galleries made by the larvae. The aim of this work was to analyse the…
Deletion of beta-fructofuranosidase (invertase) genes is associated with sucrose content in Date Palm fruit
2019
AbstractThe fruit of date palm trees are an important part of the diet for a large portion of the Middle East and North Africa. The fruit is consumed both fresh and dry and can be stored dry for extended periods of time. Date fruits vary significantly across hundreds of cultivars identified in the main regions of cultivation. Most dried date fruit are low in sucrose but high in glucose and fructose. However, high sucrose content is a distinctive feature of some date fruit and affects flavor as well as texture and water retention. To identify the genes controlling high sucrose content we analyzed date fruit metabolomics for association with genotype data from 121 date fruits. We found signif…
