In Arabidopsis, gene expression studies and analysis of knock-out (KO) mutants have been instrumental in building an integrated view of disease resistance pathways. Such an integrated view is missing in rice where shared tools, including genes and mutants, must be assembled. This work provides a tool kit consisting of informative genes for the molecular characterization of the interaction of rice with the major fungal pathogen Magnaporthe oryzae. It also provides for a set of eight KO mutants, all in the same genotypic background, in genes involved in key steps of the rice disease resistance pathway. This study demonstrates the involvement of three genes, OsWRKY28, rTGA2.1 and NH1, in the establishment of full basal resistance to rice blast. The transcription factor OsWRKY28 acts as a negative regulator of basal resistance, like the orthologous barley gene. Finally, the up-regulation of the negative regulator OsWRKY28 and the down-regulation of PR gene expression early during M. oryzae infection suggest that the fungus possesses infection mechanisms that enable it to block host defences. |

The adoption of integrated pest management (IPM) in soybean is a great example of how this technology is essential to guarantee crop sustainability and productivity. In Brazil, up to 1970, soybean was cultivated with the use of pesticides applied without the adoption of any economic threshold to base this decision. As a consequence, a six-insecticide spraying per crop season used to be the average insecticide dosage. With the introduction of Soybean-IPM, the use of pesticides was reduced to approximately two applications per season. Comparing these two contrasting situations, the advantages of using IPM methods cannot be ignored, since they are economically and mostly environmentally feasible. Despite the benefits provided by Soybean-IPM, this program was abandoned in Brazil, and its principles were almost forgotten, and, as a consequence, insecticide use increased. The success and failures of Soybean-IPM in Brazil will be further analyzed in this review in an attempt to point out how safe this technology is and whether there is any risk in fully adopting this approach. |
