Covalently closed circular (+) RNA of the potato spindle tuber viroid (PSTVd) can efficiently dimerize noncovalently upon heating and slow cooling in the presence of monovalent cations or Mg2+. In vitro transcription of subgenomic fragments reveals that the ability to dimerize resides in the "upper
6-methoxy-2-benzoxazolinone (6-MBOA), a naturally occurring progonadal compound present in grasses with structural resemblance to melatonin, was tested for antifungal activity against Fusarium oxysporum, Rhizoctonia solani and Coprinus comatus. A variety of pineal products was also examined for the
A cDNA encoding the simian-human immunodeficiency virus (SHIV 89.6p) Tat regulatory element protein was fused to the c-terminus of the cholera toxin B subunit gene (ctxB-tat) and introduced into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation methods. The fusion gene was
A cDNA fragment encoding the V3 loop of human immunodeficiency virus type-1 (HIV-1) envelope glycoprotein gp120 was fused to the cholera toxin B subunit gene (CTB-gp120) and transferred into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation. The CTB-gp120 fusion gene was
A deoxyribonucleic acid (DNA) fragment encoding the cholera toxin B subunit (CTB) was linked 5' to the simian immunodeficiency virus (SIVmac) Gag p27 capsid gene (CTB-Gag). The fusion gene was transferred into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation methods and
A cDNA encoding the Simian immunodeficiency virus type (SIV(mac)) Gag capsid protein was introduced into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation methods. The gag gene was detected in the genomic DNA of transformed leaf tissues by PCR DNA amplification. Immunoblot
The high-yield expression of a neutralizing epitope from human immunodeficiency virus type 1 (HIV-1) on the surface of a plant virus and its immunogenicity are presented. The highly conserved ELDKWA epitope from glycoprotein (gp) 41 was expressed as an N-terminal translational fusion with the potato
From the epidemiological point of view, Trichophyton rubrum is the most important dermatophyte in the Western world. Mostly, the lesions of fungal infections of the skin are restricted and circumscribed. Immunodeficiency, diabetes or treatment with steroids, however, favour widespread disease
An unusual dermatophyte was isolated from the plantar scales of a human immunodeficiency virus-positive man with tinea pedis. Morphology, physiology, and molecular data provided evidence to support the new species Trichophyton eboreum. This dermatophyte is characterized by rapid growth on common
Mycoleptodiscus indicus, a dematiaceous hyphomycete, was identified as the causal agent of subcutaneous infection in the knee of a 72-year-old male gardener residing in coastal South Carolina. The patient had Wegener's granulomatosis and immunodeficiency. Synovial fluid and biopsy tissue sections
Chicken anemia virus (CAV) is an important pathogen of chicken worldwide, causing severe anemia and immunodeficiency. Its small single-stranded DNA genome (2.3kb) encodes three proteins: VP1, the only structural protein, VP2, a protein phosphatase, and VP3, also known as apoptin, which induces
Background: Garlic (Allium sativum L.) is a common herb consumed worldwide as functional food and traditional remedy for the prevention of infectious diseases since ancient time. Garlic and its active organosulfur compounds (OSCs)
