Summary[edit] Description: English: Arceuthobium oxycedri in a Juniperus oxycedrus plant, at the Sierra de Guadarrama. Español: Arceuthobium oxycedri en su huesped, un enebro(Juniperus oxycedrus) en la Sierra de Guadarrama. Date: 2008. Source: Own work. Author: Erfil.
Collection of semi-parasitic juniper dwarf mistletoe (Arceuthobium oxycedri (DC.) M. Bieb, Santalaceae) during the botanical expedition at the Crimea. The main host of this species at the Crimean peninsula is Eastern prickly juniper (Juniperus deltoides R.P. Adams) – Mediterranean relic. A. oxycedri withdraws essential soluble carbohydrates, organic and amino acids via both xylem and phloem disturbing its phytohormonal balance, affecting its morphology, seed production ability, growth intensity, and providing entrance points for the decay fungi. Collection of both male and female A. oxycedri individuals is performed by the research fellow of the "Institute of Food Biotechnology and Genomics National Academy of Sciences of Ukraine" for further morphometry and DNA analysis. ”Novyi Svet” Botanical Reserve, about 0,5 km to the N from Novyi Svet village, Cape Kapchik, Sudak Terr., Autonomous Republic of Crimea, Ukraine (44.8274 N, 34.9013 E)
The sticky seed of juniper dwarf mistletoe (Arceuthobium oxycedri (DC.) M. Bieb) from the Crimean Peninsula ̶ a semi-parasitic species of Holarctic Cupressaceae hosts parasitizing Eastern prickly juniper, Juniperus deltoides R.P. Adams, Greek juniper, J. excelsa M. Bieb. and Oriental thuja, Platycladus orientalis (L.) Franco. Among the unique features of Arceuthobium spp. are ballistic seed dispersal primarily achieved through a hydrostatically controlled explosive discharge mechanism and thermogenesis. Seeds of A. oxycedri are ~0.9−1 mm long and ~0.4−0.5 mm wide, with an elongated pedicel on the proximal (acuminate) apex. A. oxycedri seeds are covered by a sticky viscin (“birds glue”) forming a snow-white cap on the distal (roundish) apex and thin layer on the surface of the seed. After the hydration viscin forms sticky stands required for parasite attachment to the host branch and/or sporadic ornithochory. The picture was taken using stereomicroscope Axio Zoom.V16 (Carl Zeiss, Germany). Seeds are from Mt. Malyi Sokol, Sudak territory Autonomous Republic of Crimea, Ukraine.
