Pine-pine gall rust, also known as western gall rust, is a fungal disease of pine trees.
 This plant disease is caused by Endocronartium harknessii (asexual name is "Peridermium harknessii"), an autoecious, endocyclic, rust fungus that grows in the vascular cambium of the host.
 Pine-pine gall rust is found on pine trees ("Pinus" spp.)
 with two or three needles such as ponderosa pine, jack pine, and scots pine.
 The disease is very similar to pine-oak gall rust, but its second host is another "Pinus" species.
 The fungal infection results in gall formation on branches or trunks of infected hosts.
 Gall formation is typically not detrimental to old trees but has been known to kill younger less stable saplings.
 Galls can vary from small growths on branch extremities to grapefruit sized galls on trunks.
Marchalina hellenica is a scale insect that lives in the eastern Mediterranean region, mainly in Greece and Turkey.
 It is the sole member of the genus "Marchalina".
 It lives by sucking the sap of pine trees, mainly the Turkish Pine ("Pinus brutia") and, to smaller extent, Aleppo Pine ("Pinus halepensis"), Scots Pine ("Pinus sylvestris") and Stone Pine ("Pinus pinea").
 It can be found in the cracks and under the scales of the bark of these trees, hidden under the white cotton-like wax it secretes.
 Its main form of reproduction is parthenogenesis.
Nicotiana tabacum, or cultivated tobacco, is an annually-grown herbaceous plant.
 It is found only in cultivation, where it is the most commonly grown of all plants in the "Nicotiana" genus, and its leaves are commercially grown in many countries to be processed into tobacco.
 It grows to heights between 1 and 2 meters.
 Research is ongoing into its ancestry among wild "Nicotiana" species, but it is believed to be a hybrid of "Nicotiana sylvestris", "Nicotiana tomentosiformis", and possibly "Nicotiana otophora".
Diprion similis is a species of sawfly in the family Diprionidae.
 It is native to central and northern Europe and Asia but has been accidentally introduced into North America where it has become invasive.
 The larvae feed on the needles of pine trees, especially those of the white pine ("Pinus strobus").
 In North America it is known as the introduced pine sawfly or the imported pine sawfly.
 It is also known as the white pine sawfly because of its preference for feeding on the white pine, but this name is confusing because another sawfly, "Neodiprion pinetum", whose larvae also feed on this tree, is itself known as the "white pine sawfly".
Grosmannia clavigera is a species of sac fungus that causes blue stain in wood.
 It spreads to lodgepole pine, ponderosa pine, Douglas-fir, and whitebark pine trees from the body and a special structure in the heads of mountain pine beetles.
 The blue stain fungus has evolved a relationship with mountain pine beetles that allow them to travel from tree to tree on a special structure in the beetle’s heads and stops the tree from producing resin to pitch out or kill the beetle, encouraging the pine beetle infestation occurring all along the Rocky Mountains from Mexico into Canada.
 The beetles are able to mine and lay eggs while avoiding the tree’s defenses.
 The 33 Mb genome of this fungus was sequenced in 2009.
Nicotiana sylvestris is a species of the genus "Nicotiana", known by the common names woodland tobacco, flowering tobacco, and South American tobacco.
 It is a perennial plant in the tobacco genus "Nicotiana".
Encyclia is a genus of orchids.
 The genus name comes from Greek "enkykleomai" ("to encircle"), referring to the lateral lobes of the lip which encircle the column.
 The abbreviation in the horticultural trade is E.
Nicotiana ( ) is a genus of herbaceous plants and shrubs of the family Solanaceae, that is indigenous to the Americas, Australia, south west Africa and the South Pacific.
 Various "Nicotiana" species, commonly referred to as tobacco plants, are cultivated as ornamental garden plants. "
N. tabacum" is grown worldwide for production of tobacco leaf for cigarettes and other tobacco products.
Sphaeropsis blight is a disease that affects pines worldwide.
 This disease was previously known as Diplodia tip blight.
 Sphaeropsis blight is considered to be a "disfiguring disease" that attacks pine trees that are growing under stressful conditions.
 Sphaeropsis blight does not typically kill the tree, but will significantly disfigure the tree if not properly cared for or controlled.
 Most commonly, Sphaeropsis blight attacks Austrian ("Pinus nigra"), Scots ("P. sylvestris"), and red ("P. resinosa") pine trees.
 This disease is a problem in the United States, nationwide, from coast to coast, and can be found worldwide.
Wukesong (), literally the "Five Pine Trees", is the name of the roadway interchange in Haidian District in western Beijing where Fuxing Lu, the western extension of Chang'an Avenue crosses the Fourth Ring Road.
 In the 1960s, five pine trees stood at the site during the construction of the Beijing Subway.
 The trees died but five new pines have been planted.
 Line 1's Wukesong Station has exits at each of the four corners of the interchange.
 The Beijing Wukesong Culture & Sports Center is situated northeast of the intersection.
