Pineapple is the third most crucial tropical fruit worldwide and available in five varieties. Genomes of different pineapple varieties have been released to date; however, none of them are complete, with all exhibiting substantial gaps and representing only two of the five pineapple varieties. This significantly hinders the advancement of pineapple breeding efforts.

This gene family has been extensively studied in various plant species, and its functional role in pineapple has yet to be characterized. In this study, 15 genes were identified in pineapple through a genome-wide scan and categorized into three major branches based on a phylogenetic tree.

Plant tissue culture methods, such as somatic embryogenesis, are attractive alternatives to traditional breeding methods for plant propagation. However, they often suffer from limited efficiency. Somatic embryogenesis receptor kinase ( is a marker gene of early somatic embryogenesis in several plants, including pineapple.

However, few studies focus on the development of its unique collective fruit. In this study, we generated a genome-wide developmental transcriptomic profile of 14 different tissues of the collective fruit of the pineapple covering each of the three major fruit developmental stages.
