Assessment of genetic stability and photoreceptor gene expression (CmPHYA and CmPHYB) of Chrysanthemum indicium plantlets culture on medium containing molybdenum trioxide nanoparticles
This study investigated the effects of molybdenum trioxide nanoparticles (MoO₃NPs) on the rooting, genetic stability, photosynthesis-related gene expression, and nursery-stage growth of Chrysanthemum indicum. The rooting stage analysis revealed that the 6.4 µg/L MoO₃NPs treatment significantly en...

| Izvleček: | This study investigated the effects of molybdenum trioxide nanoparticles (MoO₃NPs) on the
rooting, genetic stability, photosynthesis-related gene expression, and nursery-stage growth
of Chrysanthemum indicum. The rooting stage analysis revealed that the 6.4 µg/L MoO₃NPs
treatment significantly enhanced rooting rate, plantlet height, leaf number, root number, root
length, SPAD value, and fresh weight compared to control treatments. ITS sequence analysis
confirmed that MoO₃NPs did not induce mutations or genetic instability, with the ITS
sequences of treated plantlets showing 100% similarity with those in the NCBI database and
control samples. MoO₃NPs supplementation also upregulated the expression of CmPHYA
and CmPHYB, critical genes encoding photoreceptors involved in red and far-red light
perception, enhancing photosynthetic efficiency. At the nursery stage, plantlets derived from
MoO₃NPs-supplemented media demonstrated superior growth parameters, including plant
height, leaf and root numbers, fresh and dry weight, and SPAD value. These findings
underscore the potential of MoO₃NPs to improve plantlet development, photosynthetic performance, and nutrient absorption, thereby highlighting their role in sustainable plant production systems. |
