Kyseláková H., Sedlářová M., Kubala M., Nožková V., Piterková J., Luhová L., Novák O., Ilík P. (2013): Reactive oxygen and nitrogen species and hormone signalling in systemic infection of pea by Pea enation mosaic virus. Plant Protect. Sci., 49: 105–119. The physiological responses of pea plants during 40 days of compatible interaction with Pea enation mosaic virus (PEMV) were evaluated. PEMV i...

In this study, it was aimed to reveal some viruses that are a problem in tomato production areas the Ereğli district of Konya, where is common. For reason, 2019 season, leaf samples were taken from 160 plants showing symptoms similar virus disease such as mosaic, deformations, yellowing, blight on leaves and stunted plants. Possible infections Cucumber mosaic (CMV), Tomato spotted-wilt (TSWV) (...

The health sector often appears prominent in surveys of perceived corruption, because citizens experience the symptoms of systemic corruption most distressingly during their interaction with frontline health workers. However, the underlying drivers of systemic corruption in society may be located in other social systems with the health system demonstrating the symptoms ...

We report here that all 25 isolates of Tomato yellow leaf curl China virus (TYLCCNV) collected from tobacco, tomato, or Siegesbeckia orientalis plants in different regions of Yunnan Province, China, were associated with DNAbeta molecules. To investigate the biological role of DNAbeta, full-length infectious clones of viral DNA and DNAbeta of TYLCCNV isolate Y10 (TYLCCNV-Y10) were agroinoculated...

Biosynthesis of phenylpropanoid natural products in tobacco was perturbed by introduction of a heterologous (bean) phenylalanine ammonia-lyase (PAL; L-phenylalanine ammonia-lyase, EC 4.3.1.5) gene, modified by inclusion of cauliflower mosaic virus 35S enhancer sequences in its promoter. These transgenic plants can exhibit a series of unusual phenotypes including localized fluorescent lesions, a...

PVY is a member of the Potyviridae, the largest plant virus family. For general information on PVY see the Web Site (life.anu.edu.au/viruses/ICTVdB/57010001.htm). Currently, three main strains of PVY are know. (i) PVY (ordinary or common strain) is widely distributed throughout the potato growning areas of the world. This strain induces mild to severe mosaic and can cause stem necrosis in some ...

Background: Spine gourd (Momordica dioica Roxb. Willd) is one of the important cucurbitaceous crops grown across the world for vegetable and medicinal purposes. Diseases caused by the DNA viruses are becoming the limiting factors for the production of spine gourd reducing its potential yield. For the commercial cultivation of the spine gourd, propagation material used by most o...

A systematic field survey was conducted in ivy gourd fields of Tamil Nadu during the year 2019-2021. The infected plants manifesting prominent chlorosis, mosaic, puckering, and yellow mosaic symptoms on leaves were tested through polymerase chain reaction (PCR) assay for infection begomoviruses. Amplicons PCR from 5 samples sequenced. 4 with tomato leaf curl New Delhi virus (ToLCNDV) one Coccin...

Abstract Lower temperatures delayed development of systemic symptoms by Cauliflower mosaic virus (CaMV) in two different plant hosts. However, lower temperature exposure increased CaMV nucleic acid levels leaves systemically-infected turnips. Furthermore, altered the formation aggregates formed major inclusion body (IB) protein, P6. Finally, architecture actin cytoskeleton. These data may sugge...

Expression of the tobacco mosaic virus 30-kD movement protein (TMV MP) gene in tobacco plants increases the plasmodesmatal size exclusion limit (SEL) 10-fold between mesophyll cells in mature leaves. In the present study, we examined the structure of plasmodesmata as a function of leaf development. In young leaves of 30-kD TMV MP transgenic (line 274) and vector control (line 306) plants, almos...
