Durable resistance to blast, the most significant fungal disease of rice, represents an agronomically relevant character. Gigante Vercelli (GV) and Vialone Nano (VN) are two old temperate japonica Italian rice cultivars with contrasting response to blast infection: GV displays durable and broad resistance while VN is highly susceptible. RNA-seq was used to(More)
We focused on the functional guild of methane oxidizing bacteria (MOB) as model organisms to get deeper insights into microbial biogeography. The pmoA gene was used as a functional and phylogenetic marker for MOB in two approaches: (i) a pmoA database (> 4000 sequences) was evaluated to obtain insights into MOB diversity in Italian rice paddies, and paddy(More)
Apparent Amylose Content (AAC), regulated by the Waxy gene, represents the key determinant of rice cooking properties. In occidental countries high AAC rice represents the most requested market class but the availability of molecular markers allowing specific selection of high AAC varieties is limited. In this study, the effectiveness of available molecular(More)
Italy is the only country in Europe with a significant land area used for rice production. In this paper, the genetic diversity of 172 national varieties and 47 foreign accessions (ITALORYZA collection) was investigated using a set of neutral markers evenly distributed throughout the 12 chromosomes. Out of the 218 alleles detected in our analysis, 17 and(More)
Cultivated European rice germplasm is generally characterized by moderate to high sensitivity to blast, and blast resistance is therefore one of the most important traits to improve in rice breeding. We collected a panel of 25 rice genotypes containing 13 broad range rice resistance genes that are commonly used in breeding programs around the world: Pi1,(More)
Polygalacturonase-inhibiting proteins (PGIPs), leucine-rich repeat (LRR) proteins evolutionarily related to several plant resistance genes, bind to and regulate the action of fungal endopolygalacturonases. In Phaseolus vulgaris L., PGIPs are encoded by a gene family comprising at least five members. As a start for a systematic analysis of the regulation of(More)
Plants contain proteins that are capable of inactivating ribosomes, commonly referred to as Ribosome Inactivating Proteins (RIPs). These particular plant proteins have received attention in biological and biomedical research because of their unique biological activities towards animals and human cells as cell-killing agents. Some of the best-characterised(More)
The maize gene b-32, normally expressed in the maize (Zea mays) endosperm, encodes for a RIP (Ribosome Inactivating Protein) characterised by antifungal activity. Transgenic wheat plants were obtained via biolistic transformation, in which the b-32 gene is driven by the 35SCaMV promoter in association with the bar gene as a selectable marker. Plants were(More)
