Epicuticular Wax and White Pine Blister Rust Resistance in Resistant and Susceptible Selections of Eastern White Pine (Pinus strobus).

Proteomic comparison of needles from blister rust-resistant and susceptible Pinus strobus seedlings reveals upregulation of putative disease resistance proteins.

In order to characterize a hypersensitive-like reaction in selected Pinus strobus seedlings to Cronartium ribicola, a proteomic comparison of needles from resistant and susceptible seedlings was undertaken using two-dimensional gel electrophoresis (2-DE). The results revealed 19 polypeptides specific to resistant seedlings and seven of these specific to infected resistant seedlings. There were ...

Histology of White Pine Blister Rust in Needles of Resistant and Susceptible Eastern White Pine

Analysis of bark proteins in blister rust-resistant and susceptible western white pine (Pinus monticola).

We compared bark proteins from four contrasting (blister rust-resistant versus susceptible) half-sib seedling pairs of western white pine (Pinus monticola D. Don). Pooled proteins from resistant and susceptible groups (four trees per group) were separated by two-dimensional gel electrophoresis, silver stained, and analyzed with the aid of a laser scanner interfaced with a computerized gel docum...

COMPARISON OF EPICUTICULAR WAX ON NEEDLES AND STEMS OF Pinus eldarica WITH ITS TWO NATURALLY GENERATED FORMS

Plant cuticles are covered by epicuticular waxes with considerable ultrastructural and chemical diversity and have great systematic significance. Pinus elderica is a rare pine found naturally only in desert environment southeast of Tbilisi (Georgia). This tree have been probably introduced to Iran about 800 years ago and gradually altered in both shape and size in Nashtifan-Khaf, and changed in...

White Pine Blister Rust in High-Elevation White Pines: Screening for Simply-Inherited, Hypersensitive Resistance

Recent concern about survival and recovery of highelevation white pine ecosystems has returned white pine blister rust (caused by Cronartium ribicola) to prominence as a significant threat to forest health in the western U.S. (Samman et al., 2003). This, in turn, has spurred new research into potential rustresistance mechanisms in high-elevation white pines, including whitebark (Pinus albicauli...
