Summary: This study introduces a novel in vitro regeneration method for Rhododendron decorum using flower buds as explants. The optimal medium combinations and plant growth regulators for callus induction, adventitious shoot differentiation, proliferation, and rooting were determined. The developed regeneration system is simple, efficient, and minimally damages the mother plants, providing a foundation for plantlet propagation, genetic transformation, and new-variety breeding of R. decorum.

Summary: This study aimed to delimit species boundaries within the Rhododendron species complex, resulting in the identification of two distinct species and one putative hybrid group. The findings were based on morphological analyses and population genetic data, indicating a potential introgression event that formed the hybrid group. Further investigations are needed to validate the existence and characteristics of this hybrid group.

Summary: This study investigated the molecular mechanism responsible for the variation in flower color in Rhododendron latoucheae. Through metabolome-transcriptome analysis, it was found that differential metabolites in the flavonoid metabolic pathway were significantly enriched. Three key structural genes and four transcription factors associated with flavonoid biosynthesis were identified, which influenced the appearance of purple flower color in R. latoucheae.

Summary: The current study investigated the anthocyanins, non-anthocyanins, and free radicals scavenging potential in the flowers of Rhododendron arboreum using UPLC-ion mobility quadrupole time of flight tandem mass spectrometry. A total of twenty-five constituents were identified, including nine anthocyanins, six phenolic acids, and ten flavonoids. The extracts showed high levels of total phenolics and anthocyanin content, as well as strong antioxidant properties. The findings suggest that the flowers of Rhododendron arboreum are a promising source of bioactive compounds and can be used as functional food and nutraceuticals.

Summary: Four pairs of undescribed scalemic mixtures of chromane and chromene meroterpenoids (1a/1b-4a/4b) were isolated from Rhododendron dauricum L. The compounds demonstrated anti-inflammatory activity by inhibiting nitric oxide production in LPS-induced macrophage cells. Compound 4b exhibited significant anti-inflammatory activity and could be explored as a potential lead compound for the development of anti-inflammatory drugs.

Summary: This study examined the effects of removing Rhododendron maximum understory on southern Appalachian Mountain riparian forests. The removal of understory vegetation improved forest structure and increased soil moisture in wetter years, while larger trees were able to adapt to environmental changes in drier years without significantly altering plot-level transpiration.

Summary: Two new guaiane-derived sesquiterpenes, rhodomicranins A-B (1-2), four new cadinane-type sesquiterpenes, rhodomicranins C-F (3-6), one new eudesmane-type sesquiterpene, rhodomicranin G (7), and nine known analogues (8-16) were isolated from the roots of Rhododendron micranthum. Their structures and configurations were determined through various analytical techniques. These compounds showed significant analgesic effects in a writhing test, with compound 4 exhibiting the highest potency.
