Adaptation to iron deficiency and high pH in evergreen azaleas (Rhododendron spp.): potential resources for breeding

open access: yesEuphytica, 2017
The growth of evergreen azaleas (Rhododendron spp.) can be altered by iron (Fe) chlorosis when plants are cultivated in a neutral-alkaline substrate. In this study, morphological and physiological responses to alkalinity and Fe deficiency were evaluated in five diploid Japanese azaleas to assess their potential as resources for breeding. R.

Border Patrol: Epicuticular Leaf Wax Mediates Resistance of Azalea Genotypes (Rhododendron spp.) to Azalea Lace Bug [Stephanitis pyrioides (Scott)] [PDF]

open access: yesHortScience, 2005
Azalea lace bug (ALB) is a significant pest on azalea, with feeding injury causing speckling and discoloration on affected leaves. Feeding damage also results in a reduction of stomatal gas exchange and leaf chlorophyll content, postulated to diminish growth and flowering rates.

Effects of Debris Flow Disturbance on Vegetation, Soils, and Topography in a Steep Landscape in Central Virginia

open access: yesEarth and Space Science, Volume 13, Issue 4, April 2026.
Abstract In August 1969, intense rainfall from the remnants of Hurricane Camille triggered >150 debris flows in Fortune's Cove, a first‐order drainage basin in central Virginia. These debris flows reshaped the landscape by stripping colluvium and vegetation from hollows.

Deciphering the Key Players of the Bacterial Microbiota Associated with Aerial Crown Gall Tumors on Rhododendron: Insights into the Gallobiome

open access: yesPhytobiomes Journal
Tumorigenic agrobacteria are widespread plant pathogens causing crown gall and cane gall diseases in various agricultural crops. These pathogens genetically transform the host plant and thus form an ecological niche (galls) in which specific metabolites (

Development of Sequence Tagged Microsatellite Site (STMS) markers in Azalea [PDF]

open access: yes
A genomic library was constructed from DNA of two azalea genotypes: a Belgian pot azalea R. simsii hybrid Mevr. Van Belle and a Chinese R. simsii from Daoxian.

Consistent Trait Patterns in a Hyper Diverse Moth Clade Along a Western Himalayan Elevational Gradient

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study examines how Geometrid moth assemblages along a 1500‐m elevational gradient in the western Himalayas respond to temperature and air density shifts. While species diversity declines with elevation and turnover occurs from low to high elevations, no significant changes in morphological or flight traits were observed at the assemblage level ...

Transcriptomic and Metabolomic Analyses Reveal Differing Phytohormone Regulation in Rhododendron Cultivars in Response to Azalea Lace Bug (Stephanitis pyrioides)

open access: yesHorticulturae
Rhododendron spp., valuable ornamental plants, frequently suffer from infestations of the azalea lace bug (Stephanitis pyrioides Scott, ALB). However, the hormonal regulatory mechanisms underlying Rhododendron defense against ALB are not well understood.

Leaf trichomes and foliar chemistry mediate defence against glasshouse thrips; Heliothrips haemorrhoidalis (Bouché) in Rhododendron simsii [PDF]

open access: yes, 2016
Herbivore defence mechanisms are a costly diversion of resources away from growth and reproduction. Thus time-limited and tissue specific expression in critical plant parts is more efficient as defined by optimal defence theory.

Three species of Exobasidium causing Exobasidium leaf blight on subgenus Hymenanthes, Rhododendron spp., in Japan

open access: yesMycoscience, 2004
Three Exobasidium species causing Exobasidium leaf blight on Rhododendron of subgenus Hymenanthes in Japan are described and discussed. After examining the holotype and fresh materials of E. shiraianum on R. degronianum, its description is emended by the morphology of basidiospores that are ellipsoid to ovoid, or obovoid, 11–21 × 5–8 µm, and with 1–3 ...

Home Range and Habitat Selection of Chamois: A Systematic Review and Meta‐Analysis

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
A systematic review of 22 studies reveals a research bias toward the Alpine chamois, leaving other subspecies understudied. Males occupy larger home ranges, and the species consistently selects steep, high‐elevation terrain while avoiding snow‐covered areas and human disturbance.
