By contrast, a pangenome incorporates multiple genomes to capture the entire set of nonredundant genes in a given species, along with its genome diversity. New sequencing technologies enable researchers to produce multiple high-quality genome sequences and catalog diverse genetic variations with better precision. Pangenomic studies have detected structural variants in plant genomes, dissected the genetic architecture of agronomic traits, and helped unravel molecular underpinnings and evolutionary origins of plant phenotypes. The pangenome concept has further evolved into a so-called super-pangenome that includes wild relatives within a genus or clade and shifted to graph-based reference systems. Nevertheless, building pangenomes and representing complex structural variants remain challenging in many crops. Standardized computing pipelines and common data structures are needed to compare and interpret pangenomes.

The biosynthetic pathway of phytomelatonin is more intricate than that of melatonin in animals, occurring in plants in the endoplasmic reticulum, chloroplasts, mitochondria, and cytoplasm. By compartmentalizing phytomelatonin production within specific organelles and differentially expressing biosynthesis genes, plants may finely tune the levels of this hormone under normal growth conditions, as well as in rapid responses to changing environmental conditions. Phytomelatonin can interact with its receptor PMTR1, triggering G protein signaling, initiating ROS-Ca2+ signaling hubs, and activating MAPK cascades. Phytomelatonin's main role is promoting plant growth and development, whereas phytomelatonin-mediated resistance to numerous abiotic and biotic stresses is inducible and primed.
