“…For many years, F. verticillioides has been known to occur systemically in leaves, stems, roots, and kernels (12). These fungi can be recovered from virtually all corn kernels worldwide including those that are healthy (13)(14)(15)(16)(17). Some data suggest that the relationship between the fungus and maize is mutualistic, with the fungus producing metabolites such as fusaric acid and gibberellins that are beneficial to the plant (17).…”

“…ISR by rhizobacteria was demonstrated using both Gram-negative and Grampositive bacteria (Baker et al, 1985;Maurhofer et al, 1994;Zhou and Paulitz, 1994;Liu et al, 1995;Leeman et al, 1996;Benhamou and Belanger, 1998;Pieterse et al, 1998;Kloepper et al, 2004). Bacillus subtilis not only has been reported to trigger ISR Ryu et al, 2004), but also has been implicated in promoting plant growth and protection from fungal infection (Dal-Soo et al, 1997;Emmert and Handelsman, 1999;Bacon et al, 2001;Estevez de Jensen et al, 2002;Ryu et al, 2003). Bacterial signals have been identified that activate plant defense responses through the ethylene pathway, independent of the salicylic acid (SA) pathway or the jasmonic acid pathway .…”

Root-Secreted Malic Acid Recruits Beneficial Soil Bacteria

et al. 2008

Beneficial soil bacteria confer immunity against a wide range of foliar diseases by activating plant defenses, thereby reducing a plant's susceptibility to pathogen attack. Although bacterial signals have been identified that activate these plant defenses, plant metabolites that elicit rhizobacterial responses have not been demonstrated. Here, we provide biochemical evidence that the tricarboxylic acid cycle intermediate L-malic acid (MA) secreted from roots of Arabidopsis (Arabidopsis thaliana) selectively signals and recruits the beneficial rhizobacterium Bacillus subtilis FB17 in a dose-dependent manner. Root secretions of L-MA are induced by the foliar pathogen Pseudomonas syringae pv tomato (Pst DC3000) and elevated levels of L-MA promote binding and biofilm formation of FB17 on Arabidopsis roots. The demonstration that roots selectively secrete L-MA and effectively signal beneficial rhizobacteria establishes a regulatory role of root metabolites in recruitment of beneficial microbes, as well as underscores the breadth and sophistication of plant-microbial interactions.

Una serie de enfermedades severas de origen fungoso son diseminadas por semillas de palto, y pueden causar una disminución de la producción en aproximadamente el 14 % y una reducción de calidad en un 10 %. El presente trabajo consistió en aislar, identificar, determinar la frecuencia y el porcentaje de semillas infectadas por hongos fitopatógenos presentes en las semillas de palto. A partir del embrión y cotiledón de 200 semillas de palto de la raza Mexicana se aislo los hongos fitopatógenos en medio de cultivo Papa Sacarosa Agar. Los hongos fitopatógenos aislados e identificados a partir del embrión y cotiledón de semillas fueron Lasiodiplodia sp. con 0.5 % y 1.00 %, y Fusarium sp. con 1.50 % y 2.50 % respectivamente. La prueba de patogenicidad permitió confirmar que Lasiodiplodia theobromae y Fusarium verticillioides afectan al palto, siendo la fuente de inoculo primario y un medio de diseminación las semillas infectadas por estos patogenos.
