1. EF-1α gene and IGS rDNA sequencing of Fusarium oxysporum f. sp. vasinfectum and F. oxysporum f. sp. phaseoli reveals polyphyletic origin of strains
The fungi Fusarium oxysporum f. sp. vasinfectum (Fov) and F. oxysporum f. sp. phaseoli (Fop) are important pathogens that cause wilt on cotton and common bean, respectively. In the present study, phylogenetic trees constructed with partial sequences of the translation elongation factor gene and ribosomal intergenic spacer region of Brazilian Fov and Fop stra

2. Evaluation of a cotton germplasm collection against Fusarium wilt race 3 isolates from Egypt
Pathogenic variation of 30 isolates of Fusarium oxysporum f. sp. vasinfectum (FOV) race 3 was evaluated on seedlings of the highly susceptible cotton cultivar 'Giza 74' in greenhouse assays. FOV isolates were clustered based upon their virulence patterns. The clusters of FOV isolates were not related to their geographic origins. Fifty-five experimental cotto

3. PhoR/PhoP two component regulatory system affects biocontrol capability of Bacillus subtilis NCD-2
The Bacillus subtilis strain NCD-2 is an important biocontrol agent against cotton verticillium wilt and cotton sore shin in the field, which are caused by Verticillium dahliae Kleb and Rhizoctonia solani Kuhn, respectively. A mutant of strain NCD-2, designated M216, with decreased antagonism to V. dahliae and R. solani, was selected by mini-Tn10 mutagenesis

4. Transformation of Fusarium oxysporum f sp. vasinfectum with GFP and DsRed gene markers. / TRANSFORMAÃÃO DE Fusarium oxysporum f. sp. vasinfectum COM OS GENES MARCADORES GFP e DsRed.
Fusarium oxysporum f sp. vasinfectum, the casual agent of fusarium wilt disease of cotton, is frequent in most cottonâproducing regions in Brazil. The fungus infects roots, colonizes the rhizomes and eventually blocks the vascular system of the pseudostems, leading to the plant collapse. The Green and Red Fluorescent Proteins (GFP and DsRed) emit green and

5. Resistência de algodoeiro a murcha de fusário: métodos de obtenção de plântulas e inoculação ;avaliação de germoplasmas ; indução de resistência e caracterização da atividade enzimática
The cotton has been in the human history for ages; it is used to the confection of clothes and its subproducts are an important source of protein to the domestic animals. Because of its wide distribution in the Brazil, the ocurrence of disease has become more frequently. Among the diseases, great importance is given to the fusarium wilt of cotton (Fusarium o

6. CaracterizaÃÃo molecular, patogenicidade e transmissÃo pela semente de Fusarium oxysporum f. sp. vasinfectum em algodoeiro / Molecular characterization, pathogenicity and transmission by seeds of Fusarium oxysporum f. sp. vasinfectum in cotton
Realizou-se este estudo com o objetivo de avaliar a virulÃncia e a variabilidade genÃtica de isolados de F. oxysporum f. sp. vasinfectum (Fov), utilizando seqÃÃncias dos genes fator de elongaÃÃo da transcriÃÃo-1α (tef1) e β-tubulina (tub2), e a transmissÃo do patÃgeno a partir de sementes. Para a primeira parte do trabalho, foram utilizad

7. VdNEP, an Elicitor from Verticillium dahliae, Induces Cotton Plant Wilting
Verticillium wilt is a vascular disease of cotton. The causal fungus, Verticillium dahliae, secretes elicitors in culture. We have generated ∼1,000 5′-terminal expressed sequence tags (ESTs) from a cultured mycelium of V. dahliae. A number of ESTs were found to encode proteins harboring putative signal peptides for secretion, and their cDNAs were isolate

8. Antisense Suppression of a (+)-δ-Cadinene Synthase Gene in Cotton Prevents the Induction of This Defense Response Gene during Bacterial Blight Infection But Not Its Constitutive Expression1[w]
In cotton (Gossypium hirsutum) the enzyme (+)-δ-cadinene synthase (CDNS) catalyzes the first committed step in the biosynthesis of cadinane-type sesquiterpenes, such as gossypol, that provide constitutive and inducible protection against pests and diseases. A cotton cDNA clone encoding CDNS (cdn1-C4) was isolated from developing embryos and functionally cha
