Grapevine rootstocks can be a source of infection with non-regulated viruses

Can viruses ever be useful?

M ost of the terms used for computer viruses arc metaphors: they have a largely medical origin, and are seductive if not literally sexy. The very real worries WC have about AIDS, for example, no doubt colour the way we talk about computer viruses. At the extreme, abstractly viruses arc clearly just algorithms, and like any other algorithm they arc good for some things and not good for others. T...

UWB Mixer improvement with Regulated Voltage Source

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...

O-37: Pseudomalignant Nature of Placenta during Normal and Pathological Gestation Is Regulated by Epigenetic Mechanisms which Can be Exploited To Design Non-Invasive Fetal Dna Markers

Background Placentation shares many analogues with the development of tumors such as rapid proliferation, invasiveness, gene expression profiles especially the expression of tumor suppressor genes, oncogenes and matrixmetallo proteinases (MMPs). Thus, a placenta has been described as a pseudomalignant tissue. However, placentation is tightly regulated and any deregulation of this pseudomalignan...

Tolerance to Lime - Induced Chlorosis and Drought in Grapevine Rootstocks

Many woody crop plants such as grapevine are traditionally grown with scion varieties grafted onto rootstocks. The selection of an appropriate rootstock provides a powerful tool to manage the growth and fruiting of the scion (Jones, 2012). In the grapevine propagation, the use of rootstocks is not a new matter. The evidence of the use of rootstocks can be found out even in works written by the ...
