Fusarium-plant interaction: state of the art - a review

Abstract

Dinolfo M.I., Castañares E., Stenglein S.A. (2017): Fusarium-plant interaction: state of the art -a review. Plant Protect. Sci., 53: 61-70.One of the most important genera able to develop diseases in cereals is Fusarium which not only produces losses by the fungal presence but also mycotoxin production harmful to human and animal consumers. In the environment, plants are continuously threatened by abiotic and biotic stresses. Among the latter, pathogens gained importance mainly due to their ability to affect the plant fitness. To protect against potential attacks, plants have developed strategies in which phytohormones have an essential role. In plant-pathogen interactions, salicylic acid, ethylene, and jasmonates are the most important, but there are also auxins, gibberellins, abscisic acid, cytokinins, brassinosteroids, and peptide hormones involved in plant defence. The interaction between Fusarium species and plants used as models has been developed to allow understanding the plant behaviour against this kind of pathogen with the aim to develop several strategies to decrease the Fusarium disease effects.

Role of Plant defence system in crop protection against Fusarium pathogens

“…For instance, Arabidopsis etr1 mutants showed less symptoms of Fusarium wilt than control plants and it also increased expressions of SA-encoding genes [121]. ET signalling is responsible for plant defence responses against fungal pathogens, for instance, ET signalling impaired Arabidopsis mutants showed higher resistance for F. graminearum; however, overexpressed mutants with ET signalling elicited Fusarium susceptibility confirming the integral role of ET in Fusarium-plant interactions [122,123]. Similarly, the etr1-1 mutant enhanced plant resistance against F. oxysporum in Arabidopsis, suggesting that ETR1 is also needed for disease development [121].…”

Spatial pattern of genetic diversity in field populations of Fusarium incarnatum‐equiseti species complex

“…In this study, there was high intrapopulation genetic variation for population 1 (94.63%) which consisted largely of isolates collected from North Trinidad compared to populations 2 and 3, perhaps due to larger sample size. It was reported that for Fusarium poae isolates, genetic variability was explained by differences within rather than between Argentinean and English populations (Dinolfo et al, 2017).…”

“…Akbar et al (2018) purported that monoculture cropping may explain cases of low genetic diversity of Fusarium equiesti populations. However, Dinolfo et al (2017) also reported that geographic isolation, ecological conditions, and crop rotation systems may not have a significant effect on the genetic variability and distribution of F. poae isolates which may suggest pathosystemspecific interactions.…”

Biocontrol Potential of Bacillus subtilis and Bacillus tequilensis against Four Fusarium Species

“…The major Fusarium species that infect many foods and feed crops include F. oxysporum , F. culmorum, F. verticillioides, and F. proliferatum. F. oxysporum is one of the most critical soil-borne plant pathogens as it infects many crops and is responsible for massive crop losses [ 7 ]. F. culmorum is known to infest wheat worldwide, causing wheat blight and crown rot of cereals, resulting in detrimental losses of this economically important crop [ 8 , 9 ].…”
