Soil contamination by cadmium (Cd) poses a persistent threat to plant growth and ecosystem health. To clarify the physiological and molecular basis of Cd tolerance in Rhododendron pulchrum, a woody ornamental species, seedlings were grown for 30 d in soil amended with five Cd levels (nominal 0, 10, 50, 100 and 200 mg·k...

Soil alkalization limits the cultivation of Rhododendron, an acidophilic ornamental genus, yet the alkali tolerance threshold of R. obtusum ‘Fenzhuanglou’ remains undefined. Seedlings were exposed for 40 d to mixed alkali (NaHCO3:Na2CO3 = 9:1; 0, 50, 60, and 70 mmol·L−1), combining physiological assays with RNA-seq and...

It is demonstrated that exogenous ABA enhances freezing tolerance through multi-layered molecular regulation encompassing transcriptional buffering, translational reprogramming, and functional reallocation from photosynthesis to stress protection in an evergreen ornamental shrub.

These findings collectively support flavanone 3-hydroxylase (F3H) as a candidate regulatory node governing organ-specific flavonoid partitioning in Rhododendron yedoense var.
