Novel variants of Bacillus thuringiensis were isolated from the phylloplane of deciduous and conifer trees as well as of other plants. These isolates displayed a range of toxicity towards Trichoplusia ni. Immunoblot and toxin protein analysis indicate that these strains included representatives of the three principal B. thuringiensis pathotypes active against larvae of the orders Lepidoptera, D...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Escherichia coli is a widespread bacterium encompassing a variety of strains, ranging from highly pathogenic strains, causing worldwide outbreaks of severe diseases to avirulent, well characterized safe laboratory strains. This study evaluated the prevalence and antibiogram profiles of E. coli pathotypes isolated from the Kat River and Fort Beaufort abstraction water. A total of 171 out of 278 ...
Leaf rust, caused by Puccinia triticina (Pt), is a widely occurring disease of wheat in the North-Western Region Russia. Annual Pt surveys this region have been conducted between 2001 and 2021. In total, 740 single urediniospore isolates were analyzed over 20 years. Virulence to Lr9, Lr19 Lr24 rare 2001–2010 was not detected after 2010. Temporal variation virulence determined on Thatcher lines ...
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
This study was carried out on the biochemical aspects of chickpea cultivars and the genomic behavior of A. rabiei pathotypes 4 and 6 in four parts: 1) Determining the number of resistant genes in chickpea native cultivars, 2) Comparing the variation of sodium and potassium electrolytes concentrations in noninfected and infected seedling stems of resistant and susceptible cultivars, 3) Studyin...
The tomato pathotype of Alternaria alternata produces host-specific AAL toxin and causes Alternaria stem canker on tomato. A polyketide synthetase (PKS) gene, ALT1, which is involved in AAL toxin biosynthesis, resides on a 1.0-Mb conditionally dispensable chromosome (CDC) found only in the pathogenic and AAL toxin-producing strains. Genomic sequences of ALT1 and another PKS gene, both of which ...
Bacterial leaf blight (BLB) disease of rice caused by Xanthomonas oryzae pv. (Xoo) is one the significant constraints for production. A study was carried out to analyze virulence, genetic diversity, and population structure Xoo isolates collected from different ecosystems Karnataka, India. The taxonomic identity all 54 confirmed using a Xoo-specific PCR assay. virulence assay on set twenty-eigh...
