Charting the isophasic endophyte of dwarf mistletoe Arceuthobium douglasii (Viscaceae) in host apical buds. (1/2)
BACKGROUND AND AIMS: Dwarf mistletoes (Arceuthobium; Viscaceae) are highly specialized dioecious angiosperms parasitic on many gymnosperm hosts in the northern hemisphere. Several dwarf mistletoe species are capable of inducing an unusual form of isophasic infection in which the internal (endophytic) system proliferates even into the apical buds of its hosts. Studies of the internal endophytic system have, for the most part, focused on the parasite within secondary host tissues. The present anatomical and ultrastructural study characterizes the growth pattern of the isophasic endophytic system of Arceuthobium douglasii within the dormant apical buds of Pseudotsuga menziesii. METHODS: Semi-thin serial sections from dwarf mistletoe-infected host apical buds were mounted, stained and micrographed. Graphic files were created from the serial micrographs and these files were stacked. These stacked files were utilized to describe the pattern of growth of the endophyte within the host tissue. The interface between cells of the mistletoe and host was also examined at the ultrastructural level by transmission electron microscopy. KEY RESULTS: By utilizing a novel technique of superimposed graphics, the current study reveals an organized pattern of mistletoe distribution that penetrates further into host tissues than previously known. A consistent pattern of growth occurring even into the preformed leaves of the host is documented. CONCLUSIONS: The apparently non-intrusive growth of the parasite appears to be developmentally synchronized with that of the host. No symplastic connections were observed in the ultrastructural examination of the parasite/host interface within the apical buds of Pseudotsuga menziesii parasitized by A. douglasii or of Pinus contorta parasitized by A. americanum.

(+info)Viscaceae, also known as Viscaceae, is a family of mostly woody, hemiparasitic plants in the order Santalales, characterized by their distinctive, often sticky, yellowish-green flowers and fleshy, berry-like fruits that are important for bird dispersal.
I'm sorry for any confusion, but "Viscaceae" is not a medical term. It is a botanical term that refers to a family of plants commonly known as mistletoes. These are parasitic plants that grow on the branches of trees and shrinks, extracting water and nutrients from them. They have been used in traditional medicine in various cultures, but it's important to note that the use of such substances should be under the guidance of a healthcare professional due to potential side effects and interactions with other medications.

Mojave National Preserve April 2015 Page One
2015 has not been a very good year for flora. Nevertheless, out in the Mojave National Preserve (which is actually the central Mojave Desert), thanks to the knowledge, experience and scouting skills of our Jepson workshop leaders Jim Andre and Tasha La Doux, we were able to find and enjoy a great many species in bloom and many rare plants. We did have to do a bit more driving than has been customary on most other workshops Ive attended (15 now) but it was totally worth it. The scenery in the East Mojave alone is spectacular. We were extremely fortunate to have with us for the entire workshop Ronald B. Kelley, the main author for the family Boraginaceae in the Jepson Manual, 2nd edition, and a person who has spent countless hours in the field over a wide geographic area studying such genera as Cryptantha, Pectocarya, Plagiobothrys, and Amsinckia, and has a deep understanding of these and many other genera. We were blessed with good weather, cool though windy nights, and sunny days with ...
