Abstract

During December 2003, symptoms were observed in greenhouse tomato plants in Bet Dagan, Israel that resembled those of Tomato chlorosis virus (ToCV), a crinivirus common in the southeastern United States and southern Europe (2,3). Middle-aged leaves showed interveinal chlorosis, while more mature leaves showed more intense interveinal chlorosis with some interveinal bronzing. Symptoms were associated with the presence of Bemisia tabaci, an efficient vector of ToCV. Total nucleic acids were extracted (1) from middle-aged and mature leaves from two symptomatic plants, as well as from healthy tomato, Physalis wrightii infected with ToCV, and Nicotiana benthamiana infected with Tomato infectious chlorosis virus (TICV), another crinivirus that produces identical symptoms on tomato. Extracts were tested using hybridization with probes specific to the coat protein (CP) gene of ToCV and the HSP70h gene of TICV. Hybridization results identified the presence of ToCV in all samples from symptomatic tomato plants and ToCV-infected P. wrightii, but not in those from healthy tomato or TICV-infected N. benthamiana. TICV was only detected in TICV-infected N. benthamiana. Extracts were also subjected to reverse transcription-polymerase chain rea...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
