Editorial: Advances on genomics and genetics of horticultural crops and their contribution to breeding efforts - volume II.

This editorial published in the journal Frontiers in Plant Science discusses recent advancements in genomics and genetics of horticultural crops and their contribution to breeding efforts. The editorial highlights various research studies on topics such as selenium accumulation in tea cultivars, fern gametophytes' response to light, proteomics and metabolomics analysis of kale cultivars, genome-wide identification of gene families in mangrove species and pineapple, and the development of a single primer enrichment technology panel for lettuce. The text also mentions a study on genome editing in cabbage and a review paper on breeding for secondary metabolites content in horticultural crops. The editorial provides information on the progress made in breeding for higher accumulation of phenolic acids and flavonoids in popular vegetables such as pepper, tomato, and eggplant, using genetic and genomic technologies to discover enzymes, genes, and QTLs involved in the biosynthesis and accumulation of these compounds. The text also discusses the assembly and annotation of non-nuclear genomes, specifically the mitochondrial and chloroplastic genomes of the wax apple and three wild perennial Hordeum species, respectively. These genome studies provide insights into plant biology, phylogenetic evolution, and genetic diversity, and offer valuable information for molecular breeding and genetic improvement.
