Incidence and Distribution of Tomato yellow fruit ring virus on Soybean in Iran



A total of 1,207 symptomatic and 2,677 randomly samples were collected from soybean fields throughout Iran during the growing seasons of 2004-2006 and tested by enzyme-linked immunosorbent assay (ELISA) using specific antibodies to Tomato yellow fruit ring virus (TYFRV), a newly proposed species in the genus Tospovirus. ELISA results were confirmed by electron microscopy, host range studies, serological analysis, polymerase chain reaction and limited to few affected plants, by sequencing of a 1200 bp DNA fragment corresponding to the N gene of TYFRV. The virus was largely detected in the main soybean growing provinces of Iran with an overall incidence of 6.1%, even if its introduction in Iranian soybean fields seems to be only recent. In this study, Thrips tabaci was identified for the first time as a vector of the virus, but no transmission by soybean seeds was evidenced for the same virus. TYFRV was also detected in some weed species and for the first time in Datura metel and D. stramonium, as confirmed by biological and molecular assays.

• Physics of the Impossible by Michio Kaku

Physics of the Impossible A Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel
Written by Michio Kaku

Trade Paperback, 352 pages | Anchor | Science - Physics | $15.95 | April 14, 2009 | 978-0-307-27882-1 (0-307-27882-4)

A fascinating exploration of the science of the impossible—from death rays and force fields to invisibility cloaks—revealing to what extent such technologies might be achievable decades or millennia into the future.

One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. In Physics of the Impossible, the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.

From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals—and the limits—of the laws of physics as we know them today. He ranks the impossible technologies by categories—Class I, II, and III, depending on when they might be achieved, within the next century, millennia, or perhaps never. In a compelling and thought-provoking narrative, he explains:
· How the science of optics and electromagnetism may one day enable us to bend light around an object, like a stream flowing around a boulder, making the object invisible to observers “downstream”
· How ramjet rockets, laser sails, antimatter engines, and nanorockets may one day take us to the nearby stars
· How telepathy and psychokinesis, once considered pseudoscience, may one day be possible using advances in MRI, computers, superconductivity, and nanotechnology
· Why a time machine is apparently consistent with the known laws of quantum physics, although it would take an unbelievably advanced civilization to actually build one
Kaku uses his discussion of each technology as a jumping-off point to explain the science behind it. An extraordinary scientific adventure, Physics of the Impossible takes readers on an unforgettable, mesmerizing journey into the world of science that both enlightens and entertains.
