“…It is now a routine procedure to construct genomic resources for non-model crop species and their relatives (Wambugu and Henry, 2022). This is an important step in increasing the efficiency of interspecific breeding, especially in species that have long generation time (Valle-Echevarria et al, 2021). Transcriptomes provide insight into gene function and are a potentially rich source of information on crop relatives.…”

Macadamia tetraphyllais a wild relative of the economically valuable cropMacadamia integrifolia. Genomic knowledge of crop wild relatives is central to determining their possible role in breeding programs to mitigate biotic and abiotic stress in the future. The goal of this project was to develop a genomic resource for macadamia agriculture in Hawai‘i through constructing a transcriptome ofM. tetraphyllaand testing for hybridity in University of Hawai‘i at Mānoa breeding material. The transcriptome assembly ofM. tetraphyllarevealed large differences in gene expression attributable to tissue type. Advanced breeding lines (HI862 and HI879) appear to be hybridized with the crop wild relativeM. tetraphylla. Additionally, a putativeM. tetraphyllatree sampled from a remnant orchard planting at the Waimānalo research station on Oahu did not match anecdotal accounts of the orchard as it appeared to be of hybrid ancestry.

“…CRISPR/Cas9 genome editing technology. 105 First, the applications of CRISPR/Cas9 were limited to creating only deletion. Still, modern variants of CRISPR-based genome editing technologies are more advantageous due to new modifications and can produce targeted insertions, exchange amino acids, and modulate gene expression.…”

Integrating genomics and genome editing for orphan crop improvement: a bridge between orphan crops and modern agriculture system

et al. 2023

Domestication of orphan crops could be explored by editing their genomes. Genome editing has a lot of promise for enhancing agricultural output, and there is a lot of interest in furthering breeding in orphan crops, which are sometimes plagued with unwanted traits that resemble wild cousins. Consequently, applying model crop knowledge to orphan crops allows for the rapid generation of targeted allelic diversity and innovative breeding germplasm. We explain how plant breeders could employ genome editing as a novel platform to accelerate the domestication of semi-domesticated or wild plants, resulting in a more diversified base for future food and fodder supplies. This review emphasizes both the practicality of the strategy and the need to invest in research that advances our understanding of plant genomes, genes, and cellular systems. Planting more of these abandoned orphan crops could help alleviate food scarcities in the challenge of future climate crises.

“…A promising method for the quick adaptation of existing crop wild relatives is gene-editing, as demonstrated in case studies of tomato and ground cherry (Lemmon et al, 2018). However, consumer acceptance of gene-editing is unlikely to be acceptable for the entire global and infeasible for semidomesticated, orphan, or landrace species because of their limited information (Del Valle-Echevarria et al, 2021). Further, for many traits specific genes and causative mutations are not known so it would be difficult to operationalize gene editing.…”

Climate change is threatening the status quo of agricultural production globally.Perennial cropping systems could be a useful strategy to adapt agriculture to a changing climate. Current and future perennial row crop systems have many and varied applications and these systems can respond differently than annuals to agricultural challenges resulting from climate change, such as shifting ranges of plant, pathogen, and animal species and more erratic weather patterns. To capitalize on attributes of Abbreviations: GHG, greenhouse gas; TLI, the intermediate wheatgrass population; UAS, unmanned aerial systems.
