Genome-wide identification and comparative analysis of strigolactone biosynthetic genes in major solanaceous crops.

ABSTRACT: Strigolactones (SLs) are a class of important plant hormones that not only regulate plant growth and development but also mediate responses to biotic and abiotic stresses. Functioning as signaling molecules derived from the rhizosphere, SLs play a pivotal role in inducing the germination and facilitating the parasitism of root holoparasites such as Orobanche spp. Notably, the parasitism success of Orobanche exhibits marked variation within Solanaceous crops, demonstrating dual dependence on SL exudation dynamics and edaphic phosphate bioavailability. We performed a genome-wide characterization of SL biosynthetic orthologs across nine Solanaceous species through integrated phylogenomic pipelines alongside qRT-PCR expression profiling. In this study, we identified 113 putative SL biosyntheti
