The BRS Novaera genotype presents a possible resistance through antixenosis and antibiosis to Callosobruchus maculatus.
To investigate whether the effect of antibiosis is systemic or localized to the aphid feeding zone, other potted plants were prepared in a similar manner but were previously infested with 25 to 35 aphids per plant at the vegetative growth stage (2 wk after transplant), and 100 to 200 aphids per plant at the reproductive stage (10 wk after transplant).
sobresalientes, las cuales, en confrontaciones contra cepas de Fusarium sp., presentaron uno o mas de los mecanismos de antagonismo de competencia por espacio y nutrientes, micoparasitismo y antibiosis.
Therefore, cluster I genotypes and Zapalote Chico have the potential to be used in genetic breeding to stack genes for antibiosis and non-preference resistance and, in consequence, to increase resistance to S.
In this preliminary study, leaves of the common bean were evaluated for antixenosis and antibiosis in the laboratory.
Relationship of in vitro antibiosis of plant growth-promoting rhizobacteria to plant growth and the displacement of root microflora.
La inhibicion del crecimiento de Fusarium sp.se observo en todos los tratamientos, posiblemente por la accion antagonica mediada por antibiosis, caracteristico de estas especies de biocontroladores.
"We know from numerous studies that chlorhexidine is superior to iodine, but we also have found that with these wipes you get a level of antibiosis on the skin surface that decreases surgical site infections at the time of incisions," Dr.
Comparative genomic studies of the causal agents and of their antagonists might reveal genes involved in virulence and genes involved in antibiosis. Additionally, the search for new pineapple genotypes that are more resistant to pink disease could greatly reduce the economic impact of this disease in pineapple market.
(2002), besides the previously mentioned factors, one of the most important indicators of antibiosis is larval death, which can be evidenced by the low number of emerged adults, as in the case of BR-IRGA 409, IRGA 424, IRGA 427 and IRGA 425, which showed the lowest values of emerged insects.
Several mechanisms have been suggested to be responsible for the effects of these BCAs, these include competition for space and nutrients, mycoparasitism, metabolite production, antibiosis and inducing plant systemic resistance [26].
