Orchids have high economic value so that they are potential to be cultivated. The species most popular with people Dendrobium and Phalaenopsis. However, there major obstacles can affect orchid growth, namely viral infections. type of virus reported infect the is ORSV. This infection inhibit plant reduce flower quality marketability. There also symptoms in form mosaic, chlorotic, streak, necrosi...

Plants including pepper, red kidney bean, squash, string bean and tomato, as well as weeds with viral symptoms were collected from five districts in Belize over a three year period with the aim of determining the diversity of the begomoviruses present. Sixty five percent of the samples screened via DNA hybridization produced signals indicative of begomovirus infection. Subsequent PCR amplificat...

Research Problem: Cassava leaves play an important role in the diet of Central African population. Several studies have investigate composition nutrients cassava but only few study focused on impact mosaic virus disease, main threat production sub-Saharan Africa, nutritional value infected leaves. The objective this work is to determine content and anti-nutritional compounds by healthy leaves.&...

Gerbera spp., which is in the Asteraceae family, most widely cultivated cut flower ornamental plant Türkiye after carnation. Approximately 74% of Türkiye's production met from Antalya province. Virus diseases are a problem cultivation as they significantly reduce yield and quality. In this study, was carried out to detect some virus seen areas province, surveys were commercial 2021-2022 season....

golestan province is one of the main tobacco growing regions in the country. tobacco streak virus (tsv) is a destructive pathogen on tobacco that has a wide host range and occurs worldwide. in order to serological detection of tsv at 13 region of golestan province, 500 infected samples belong to 8 families; chenopodiacae, amaranthaceae, fabaceae, solanaceae, malvaceae, poaceae, cucurbitaceae an...

Here we reported a novel protein elicitor from Bacillus amyloliquefaciens NC6 induced systemic resistance (ISR) in tobacco. The purification was executed by ion-exchange chromatography, native-page extraction and HPLC, and the amino acid sequence was identified by mass spectrometry. This recombinant elicitor protein, expressed in Escherichia coli by an E1 expression vector, had good thermal sta...

Tomato bushy stunt virus particles have previously been physically and chemically well characterized. Different strains, however, are known to have different host plants and symptoms, and they can be distinguished serologically. In an attempt to correlate this behavior with physicochemical properties, we have performed a comparative study on isolates of four of the main variants of this virus (...

Tomato bushy stunt virus (TBSV) was detected in tomato crop (Lycopersicon esculentum) in Egypt with characteristic mosaic leaf deformation, stunting, and bushy growth symptoms. TBSV infection was confirmed serologically by ELISA and calculated incidence was 25.5%. Basic physicochemical properties of a purified TBSV Egh isolate were identical to known properties of tombusviruses of isometric 30-...

The wild-type strain (Cl-WT) of Clover yellow vein virus (ClYVV) systemically induces cell death in pea cv. Plant introduction (PI) 118501 but not in PI 226564. A single incompletely dominant gene, Cyn1, controls systemic cell death in PI 118501. Here, we show that activation of the salicylic acid (SA) signaling pathway enhances ClYVV virulence in susceptible pea cultivars. The kinetics of viru...

Wilson, A. D., and Halliwell, R. S. 1985. Characterization and field studies of a cucumber mosaic virus isolate from spinach in the Winter Garden area of Texas. Plant Disease 69:751-754. An isolate of cucumber mosaic virus (CMV) was identified from spinach in the Winter Garden area a of Texas. The isolate was very closely related serologically to strain S of CMVand is designated the Texas spina...
