“…Authors suggested that in silenced plants a shift in source to sink carbon partitioning occurred via the modulation of resource allocation via cell wall polysaccharides and raffinose metabolisms. For fruit trees, and in particular those harboring stone fruit, genetic transformation is still a long way for the difficulty to regenerate transformed plants (Prieto, 2011). However, it is possible by using agricultural practices to modify the carbon flux as demonstrated by covering with plastic film tangerine trees (Jin et al, 2018).…”

Cell wall turnover and modification in its composition are key factors during stone fruit development and patterning. Changes in cell wall disassembly and reassembly are essential for fruit growth and ripening. Modifications in cell wall composition, resulting in the formation of secondary cell walls, are necessary for producing the most distinctive trait of drupes: the lignified endocarp. The contribution of primary metabolism to cell wall synthesis has been investigated in detail, while the knowledge on the contribution of the cell wall to primary metabolites and related processes is still fragmented. In this review, starting from peculiarities of cell wall of drupes cells (in mesocarp and endocarp layers), we discuss the structure and composition of cell wall, processes related to its modification and contribution to the synthesis of primary metabolites. In particular, our attention has been focused on the ascorbate synthesis cell wall-related and on the potential role of cyanogenic compounds in the deposition of the secondary cell wall.

“…Unravelling the gene function in peach development has increased in a post-genomic scenario [39] and molecular tools have efficiently supported marker assisted breeding [40]. Notably, the peach recalcitrance to genetic transformation still hampers gene function studies and cultivar improvement [41,42].…”

“…Notably, the peach recalcitrance to genetic transformation still hampers gene function studies and cultivar improvement [41,42]. Ten peach KNOX genes (KNOPEs) were previously characterized, positioned on the Prunus reference map; the positions of some of them were compatible with fruit QTLs [43].…”

“…Others have begun to probe the complex responses to abiotic stresses using genome-wide omic technologies such as transcriptomics, proteomics, methylomics, and metabolomics (Yaish and Kumar, 2015;Safronov et al, 2017;Yaish et al, 2017;Al-Harrasi et al, 2018;Rikek et al, 2019). Other recent developments include advances in transformation strategies for genetic engineering and gene editing (Prieto, 2011;Cardi et al, 2017), use of heterologous expression systems for studies of gene function (Patankar et al, 2019a,b), improvements to the date palm genome (Hazzouri et al, 2019), and demonstration of genome-wide association studies (GWAS) for mapping phenotypic trait variation in date palm (Hazzouri et al, 2019). Despite these advances, there is presently limited prospect of crop improvement using conventional breeding or genomic selection owing to many challenges faced by perennial fruit crops (Laurens et al, 2012).…”

Prospects for the Study and Improvement of Abiotic Stress Tolerance in Date Palms in the Post-genomics Era

Date palm (Phoenix dactylifera L.) is a socioeconomically important crop in the Middle East and North Africa and a major contributor to food security in arid regions of the world. P. dactylifera is both drought and salt tolerant, but recent water shortages and increases in groundwater and soil salinity have threatened the continued productivity of the crop. Recent studies of date palm have begun to elucidate the physiological mechanisms of abiotic stress tolerance and the genes and biochemical pathways that control the response to these stresses. Here we review recent studies on tolerance of date palm to salinity and drought stress, the role of the soil and root microbiomes in abiotic stress tolerance, and highlight recent findings of omic-type studies. We present a perspective on future research of abiotic stress in date palm that includes improving existing genome resources, application of genetic mapping to determine the genetic basis of variation in tolerances among cultivars, and adoption of gene-editing technologies to the study of abiotic stress in date palms. Development of necessary resources and application of the proposed methods will provide a foundation for future breeders and genetic engineers aiming to develop more stress-tolerant cultivars of date palm.
