The effective management of Verticillium wilts (VW), diseases affecting many crops and caused by some species of the soil-borne fungus Verticillium, is problematic. The use of microbial antagonists to control these pathologies fits modern sustainable agriculture criteria. Pseudomonas fluorescens PICF7 is an endophytic bacterium isolated from olive roots with demonstrated ability to control VW o...

En México se cultivan variedades algodón de ciclo largo (170 días siembra a cosecha) y abundante crecimiento vegetativo, que no son las más idóneas para regiones como la Comarca Lagunera, porque requieren una alta inversión en insumos agua, fertilizantes e insecticidas, lo cual trae consigo altos costos producción. El problema agrava suelos infestados con el hongo Verticillium dahliae K., causa...

ABSTRACT A precise real-time polymerase chain reaction (PCR) assay was developed for quantifying Verticillium albo-atrum DNA. The assay was used in a repeated experiment to examine the relationship between the quantity of pathogen DNA detected in infected leaves and shoots and the severity of Verticillium wilt symptoms in several alfalfa cultivars expressing a range of disease symptoms. Plants ...

Elucidating the mechanism of resistance to biotic and abiotic stress is of great importance in cotton. In this study, a gene containing the NAC domain, designated GbNAC1, was identified from Gossypium barbadense L. Homologous sequence alignment indicated that GbNAC1 belongs to the TERN subgroup. GbNAC1 protein localized to the cell nucleus. GbNAC1 was expressed in roots, stems, and leaves, and ...

Verticillium dahlia Kleb. is a soil-borne pathogen which causes worldwide economically important plant and yield losses. So far no resistance preventing the fungus from growing in the plants could be found in the genus Fragaria. But there are cultivars with different levels of tolerance. In particular after the ban on chemical control with effective soil disinfectants (methylbromid) cultivation...

cotton cultivar coker has been already transformed with recombinant pbi121-chi via agrobacterium tumefaciens. the t-dna region of pbi121-chi carries the chitinase (chi ) gene from bean and is under the control of the camv35s promoter. t1 and t2 progenies of transgenic cotton containing the chi gene were used in this study.  polymerase chain reaction (pcr), southern and western blotting data con...
