Effect of growth hormones on some antioxidant parameters and gene expression in tomato.
TLDR
The analytical quantification of target gene expression showed the induced effect of NAA on SOD expression and reducing effect of the other bioregulators (IAA and IBA) on CAT and TPX1 expression, however, at the protein level, it was found that IBA and IAA caused a minor effect on total protein content while a significant effect was recorded on the total protein level using NAA.
Characterization, cloning, expression and bioassay of vip3 gene isolated from an Egyptian Bacillus thuringiensis against whiteflies
TLDR
This study showed for the first time the high toxicity of the expressed Vip3 proteins of B. thuringiensis toward whiteflies as a hopeful and promising bio-control agent.
Expression of 1B capsid protein of Foot-and-mouth disease virus (FMDV) using baculovirus expression system and its validation in detecting SAT 2- specific antisera
TLDR
The sequence coding for 1B subunit of FMDV capsid was expressed in insect cells using the baculovirus expression system under the polyhedrin (polh) promoter and revealed that a protein concentration as low as 25 ng could detect SAT 2-specific antibodies in ELISA.
Evaluation of two viral isolates as a potential biocontrol agent against the Egyptian cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae)
TLDR
Spli-6 and Spli-7 proved to possess promising insecticidal properties for the development of virus-based biopesticide for the control of S. littoralis and suggest the existence of genotypic variants between both isolates.
Molecular and serological studies on a plant virus affecting strawberry
TLDR
The isolated virus was given the name strawberry leaf curl geminivirus (StLCV) and it represents the first record of WTG that infect strawberry plants in Egypt.
BIOLOGICAL AND MOLECULAR STUDIES ON THE TOXIC EF-FECT OF VEGETATIVE INSECTICIDAL PROTEIN (VIPs) OF Ba-cillus thuringiensis EGYPTIAN ISOLATES AGAINST WHITEFLIES
TLDR
Analysis of median lethal concentration (LC50) revealed that B. thuringiensis strain BtC-18 is more potent and toxic than BtDI-29 strain against whiteflies with an estimated LC50 of 90 ppm and 160 ppm for Bt C-18 and Bt DI-29, respectively.
ISOLATION AND CHARACTERIZATION OF A GEMINIVIRUS ISOLATED FROM SUGAR BEET PLANTS IN EGYPT
TLDR
It is suggested that the virus presented in this study can be considered as a new isolate of Tomato yellow leaf curl virus (TYLCV) based on transmission patterns, virus host range, and sequence analysis of C1 region of viral genome.
Molecular characterization and biological activity of native Spodoptera littoralis nucleopolyhedrovirus isolate
Background Spodoptera littoralis nucleopolyhedrovirus (SpliNPV) is considered a promising biocontrol agent that can be used for the effective control of the cotton leaf worm, Spodoptera littoralis
IMPROVEMENT OF SOME NUTRITIONAL VALUES OF TOMATOES VIA SALINITY
The antioxidant activity status is important to determine the nutritional value of fruits and vegetables. Increased antioxidant levels not only have high benefits in preventing widespread human
EXPRESSION OF RECOMBINANT US9 PROTEIN OF BOVINE HERPESVIRUS TYPE1.1 (BOHV-1.1) IN INSECT CELL LINE AND EXAMINE ITS APPLICATION IN AN IMMUNO ASSAY FOR THE DIAGNOSIS OF BOHV-1.1 INFECTED CATTLE
TLDR
The effectiveness of using of the expressed US9 protein as antigen for anti-US9 detection in serum samples infected with BoHV-1 was discussed in details.
