| iseases caused by fungal and bacterial pathogens like Magnaporthe oryzae and Xanthomonas oryzae pv. oryzae are responsible for considerable yield loss. Up to now, in rice, the modification of the expression of more than 60 genes from diverse origins has shown beneficial effects with respect to disease resistance. In this paper, we review this large set of data to identify the best genes and strategies to achieve disease resistance by transgenic approaches. Altered expression of genes involved in signal transduction and transcription may lead to many unwanted side effects, like lesion mimic phenotypes. Moreover, modification of resistance to abiotic stress has been neglected and should be carefully examined in the future. Genes like resistance genes and... |

| Laccases have numerous biotechnological applications, among them food processing. The widespread use of laccases has increased the demand for an inexpensive and safe source of recombinant enzyme. We explored the use of a rice-based system for the production of two fungal laccases derived from the ascomycete Melanocarpus albomyces and the basidiomycete Pycnoporus cinnabarinus. High-expression levels of active recombinant laccases were achieved by targeting expression to the endosperm of rice seeds. The laccase cDNAs were fused to a plant-derived signal sequence for targeting to the secretory pathway, and placed under the control of a constitutive seed-specific promoter fused to an intron for enhanced expression. This construct enabled the recovery of on... |

| Wall-associated protein kinases (WAKs) are a new group of receptor-like kinases recentlyidentified in Arabidopsis and in rice. A gene responsible for the quantitative resistance toFusarium oxysporum in Arabidopsis, RFO1, encodes a WAK-like protein (WAKL22) (Dienerand Ausubel, 2005). This finding suggests an important role for some WAKs in diseaseresistance. The first WAK in rice was recently identified as OsWAK1. The induction andoverexpression of this gene in rice led to enhanced resistance to rice blast (Li et al., 2008).Furthermore, WAKs also seem to interact with a wide range of proteins involved in cell-wallcomposition, phosphorylation or transcription processes (Li et al., 2008, Rohila et al., 2006,Yang et al., 2003). Altogether, the evidences... |
