Disease Note First Report of Tomato Infectious Chlorosis Virus from Tomato in Apulia, Southern Italy
A severe disease of tomato was observed in 2010 in a greenhouse in the province of Lecce (Apulia, southern Italy). Plants showed interveinal yellowing and thickening of mature leaves and a bushy appearance of the new growth. Pale-yellow spots, which became sunken and necrotic, were scattered on the fruit surface. Leaf symptoms were reminiscent of those induced by Tomato chlorosis virus (ToCV) o...
In plants, the excess of several heavy metals mimics iron (Fe) deficiency-induced chlorosis, indicating a disturbance in Fe homeostasis. To examine the level at which heavy metals interfere with Fe deficiency responses, we carried out an in-depth characterization of Fe-related physiological, regulatory, and morphological responses in Arabidopsis (Arabidopsis thaliana) exposed to heavy metals. E...
The goals of this study were to document the development of ozone-induced foliar injury, on a leaf-by-leaf basis, and to develop ozone exposure relationships for leaf cohorts and individual tall milkweeds (Asclepias exaltata L.) in Great Smoky Mountains National Park. Plants were classified as either ozone-sensitive or insensitive based on the amount of foliar injury. Sensitive plants developed...
Nucleolar proteins play important roles in plant cytology, growth, and development. Fibrillarin2 is a nucleolar protein of Nicotiana benthamiana (N. benthamiana). Its cDNA was amplified by RT-PCR and inserted into expression vector pEarley101 labeled with yellow fluorescent protein (YFP). The fusion protein was localized in the nucleolus and Cajal body of leaf epidermal cells of N. benthamiana....
Rhizobial-induced chlorosis in soybeans (Glcine uinax.) is caused by a phytotoxin produced in the nodules of the affected plants (1, 4). The phytotoxin has been isolated from nodules and partially characterized as a low molecular-weight amino compound (3). In the previous paper we reported finding an unidentified amino acid (unknown Y) in soybean nodules, the metabolism of which appeared to be ...
A simple bacteriological technique involving inhibition zone production on a lawn of Escherichia coli was developed to detect antimetabolite toxin production by phytopathogenic species of Pseudomonas. It was established that the mechanism of E. coli inhibition paralleled that of phytotoxin-induced chlorosis of plant tissue. Derivatives of Pseudomonas tabaci and Pseudomonas phaseolicola which di...
We experimentally isolated and characterized a CFEM protein with putative GPI-anchored site BcCFEM1 in Botrytis cinerea. BcCFEM1 contains a CFEM (common in several fungal extracellular membrane proteins) domain with the characteristic eight cysteine residues at N terminus, and a predicted GPI modification site at C terminus. BcCFEM1 was significantly up-regulated during early stage of infection...
