The goal of this study was to assess the reproductive capacity of <em>A. thracica</em> (pollen and seeds viability) and its reproductive structures, and to characterize the chemical profile and the antimicrobial activity of its essential oil (EO). The male and female generative spheres show that <em>A. thracica</em> reproduces via sexual reproduction. Furthermore, the normal progression of processes leading to pollen and seed formation is essential for fully realizing reproductive capacity. Despite the high fertility observed in the pollen of the target species, seed viability was found to be very low. Further, the female gametophyte of <em>A. thracica</em> is highly influenced by environmental conditions, which directly affect the quality of the seeds produced. Moreover, the lack of alternative reproductive mechanisms, such as apomixis, limits the plasticity of <em>A. thracica</em> populations, reducing their adaptability to environmental changes. Overall, the composition of <em>A. thracica</em> EO was notably different from that of other <em>Achillea</em> species within Sec. <em>Filipendulinae</em>.

A total of 73 <em>PgLBD</em> genes were identified, and phylogenetic analysis classified these genes into two major categories: Class I (84 %) and Class II (16 %).

Chemical quantification and <em>in vitro</em> functional analyses have identified daidzin as a key regulator of root architectural plasticity in this species. Using an integrated approach combining <em>Arabidopsis thaliana</em> (L.) root phenotyping system, cellular thermal shift assays (CETSA) and thermal proteome profiling (TPP), daidzin was demonstrated to modulate root development via stem cell-related processes and auxin signaling pathways. Specifically, daidzin led to the reduced auxin levels, silenced <em>DR5::GFP</em> expression in the stele, and suppressed PIN protein expression accompanied by a lateral shift in PIN2 polarity. Furthermore, daidzin decreased SHR, SCR, PLT1, and PLT2 protein levels while increasing WOX5 and CYCD6;1 accumulation.
