Endoplasmic reticulum as a storage site for allergenic proteins in pollen grains of several Oleaceae
Protoplasma, 1995Co-Authors: María Isabel Rodríguez-garcía, M. C. Fernández, Juan De Dios Alché, Adela OlmedillaAbstract:The ultrastructure of mature pollen grains of several Oleaceae species (Olea europaea, Fraxinus excelsior, Syringa vulgaris, Ligustrum vulgare, andForsythia suspensa) was studied and the immunolocalization of Ole e I, the major allergen of olige pollen, was determined by immunogold labelling. The five Oleaceae pollens studied here showed different intensities of labelling. The Ole e I allergen was localized throughout the rough endoplasmic reticulum. The absence of gold particles in other cell compartments, such as nuclei, pastids, mitochondria, dictyosomes, lipid bodies, and cell wall, as well as the absence of labelling in control preparations, indicate the specificity of immunolocalization. We conclude that endoplasmic reticulum of the mature pollen grain is a storage site for allergenic proteins and is probably also involved in their synthesis.

Jasminum parceflorum (Oleaceae), a new species from southern Yunnan, China.
PhytoKeys, 2020Co-Authors: Kai Zhang, Bo Pan, Lianxuan Zhou, Dianxiang ZhangAbstract:Jasminum parceflorum (Oleaceae), a new species from tropical limestone habitats in Yunnan, China, is described and illustrated here. The new species is similar to J. pierreanum and J. rarum, but can be distinguished by its linear calyx lobes, dry calyces without ridges, terminal 1 (or 3)-flowered cymes and axillary solitary flowers.

Jasminum honghoense sp. nov. (Oleaceae), from the dry‐hot Yuanjiang valley in Yunnan, China
Nordic Journal of Botany, 2019Co-Authors: Kai Zhang, Shuai Yuan, Bo Pan, Gui Zeng, Dianxiang ZhangAbstract:Jasminum honghoense (Oleaceae), a new species from the dry‐hot Yuanjiang valley in southern central Yunnan, China, is described and illustrated. Differences between J. honghoense and two morphologically similar species are presented. Moreover, the pollen morphology of J. honghoense is reported.

On the biology of Ceratopemphigus zehntneri Schouteden (Hemiptera: Aphididae), a gall-forming aphid on Ligustrum robustum subsp. walkeri (Oleaceae), in Sri Lanka.
Zootaxa, 2010Co-Authors: Matthew J.w. Cock, Richard Shaw, Roger L. BlackmanAbstract:Observations on the biology, ecology, galls and associated insects of Ceratopemphigus zehntneri Schouteden (Hemiptera: Aphididae), a gall-forming aphid on Ligustrum robustum subsp. walkeri (Oleaceae) in Sri Lanka, are presented. Stages of gall formation and details of different stages of the aphid are illustrated. The implications for biological control of L. robustum walkeri in Mauritius and La Reunion are discussed.
