Tomato Cell Death Mediated By Complementary Plant Viral Satellite RNA Sequences

Molecular Plant-Microbe Interactions, 1998
Cell death (necrosis) and severe yellowing (chlorosis) in tomato are induced by cucumber mosaic virus (CMV) supporting particular satellite RNAs. To determine whether CMV RNA sequences also are needed to induce necrosis or chlorosis, tomato seedlings ...

First Report of Tomato chlorosis virus and Tomato infectious chlorosis virus in Tomato Crops in France

Plant Disease, 2005
Since 2002, yellowing symptoms associated with high levels of white-fly populations have been observed in plants of protected tomato crops in France. Symptomatic plants exhibited interveinal yellowing areas in older leaves, followed by generalized yellowing. Symptoms were not observed in young plants or fruits.

Tomato chlorosis virus infection represses chloroplast related genes in tomato.

Physiological and Molecular Plant Pathology, 2021
Abstract Tomato chlorosis virus (ToCV) causes mild to severe chlorosis on tomato leaves. Although it has been postulated that chlorosis is caused by changes in biosynthesis, degradation, function and/or structure of chlorophyll, mechanisms of virus-induced chlorosis has not been explored to date.

First Report of the Occurrence of Tomato chlorosis virus and Tomato infectious chlorosis virus in Taiwan

Plant Disease, 2004
Pronounced yellowing symptoms on the lower leaves of tomato plants, similar to those caused by nitrogen deficiency, were observed in the spring of 1998 in The Asian Vegetable Research and Development Center and in farmers' fields in southern Taiwan.

NTRC and Chloroplast-Generated Reactive Oxygen Species Regulate Pseudomonas syringae pv. tomato Disease Development in Tomato and Arabidopsis

Molecular Plant-Microbe Interactions, 2012
Coronatine (COR)-producing pathovars of Pseudomonas syringae, including pvs. tomato, maculicola, and glycinea, cause important diseases on tomato, crucifers, and soybean, respectively, and produce symptoms with necrotic lesions surrounded by chlorosis ...

First Report of Tomato chlorosis virus in Italy

Plant Disease, 2001
During winter 2000-2001, an unusual disease of tomato was observed in some greenhouses in Sardinia, Sicily, and Apulia, in southern Italy. Plants were chlorotic and reduced in size, expanded leaves showed interveinal yellowing, and older leaves developed interveinal reddish-bronze necrosis and downward rolling.

First report of Tomato chlorosis virus on tomato crops in Cyprus [PDF]

Plant Pathology, 2006
In the summer of 2004, yellowing symptoms similar to those causedby nitrogen and/or magnesium deficiency were observed in field- andglasshouse-grown tomatoes ( Lycopersicon esculentum ), in the Parekklisiaarea of Cyprus. Initially, lower leaves showed extensive interveinal yellowingwith necrotic flecks, brittleness and occasional upward leaf rolling ...

DETEKSI MOLEKULER PENYEBAB PENYAKIT KUNING (Tomato chlorosis virus DAN Tomato infectious chlorosis virus) PADA TANAMAN TOMAT (MOLECULAR DETECTION CAUSED YELLOWING DISEASE (Tomato chlorosis virus AND Tomato infectious chlorosis virus) ON TOMATOES)

Jurnal Perlindungan Tanaman Indonesia, 2017
ABSTRACTThis research was aimed to detect the ToCV and TICV caused yellowing disease on tomatoes by molecular detection. Leaf samples of symptomatic plants were taken from Ketep (Magelang), then the leaves were identified by reversetranscription-polymerase chain reactions (RT-PCR) using specific primer ToCV-CF/ToCV-CR (360 bp) and TICVCF/TICV-CR (416 ...
