thaumatin/oryza sativa

Background: Canola is an agro-economically oilseed crop. Yield loss due to fungal disease of stem rot caused by Sclerotinia sclerotiorum is a serious problem in canola cultivation. Thaumatin-like proteins are large groups of the pathogenesis-related proteins which provide resistance to the fungal

We have used three kinds of stresses, including the signaling compound jasmonic acid, an environmental stressor, UV irradiation, and a heavy metal salt copper chloride, to study changes in the protein patterns in rice (Oryza sativa L.) leaf tissues using two-dimensional polyacrylamide gel

Thaumatin-like protein kinases (TLPKs) are defense related proteins having antimicrobial property. Herein, we identified two TLPKs in the genome of Brachypodium distachyon and Oryza sativa, four in Hordeum vulgare and Sorghum bicolor, and 16 in Triticum aestivum. All the TLPKs were located at only

Pathogenesis-related (PR) proteins associated with degradation of structural components of pathogenic filamentous fungi were overexpressed in the two-rowed malting barley (Hordeum vulgare L.) cultivar Conlon. Transgenes were introduced by co-bombardment with two plasmids, one carrying a rice (Oryza

The best known silicon (Si)-accumulating plant, rice (Oryza sativa L.), stores most of its Si in leaves, but the importance of Si has been limited to a mechanical role. Our initial studies showed that Si-induced cadmium (Cd) tolerance is mediated by the enhancement of instantaneous

Pathogenesis-related group 5 (PR5) plant proteins include thaumatin, osmotin, and related proteins, many of which have antimicrobial activity. The recent discovery of PR5-like (PR5-L) sequences in nematodes and insects raises questions about their evolutionary relationships. Using complete plant

Canola (Brassica napus) plants were co-transformed with two pathogenesis-related protein genes expressing a Trichoderma atroviride chitinase with a chitin-binding domain (chimeric chitinase) and a thaumatin-like protein (tlp) from Oryza sativa conferring resistance to phytopatogenic fungi by

The root-knot nematode Meloidogyne graminicola is responsible for production losses in rice ( Oryza sativa ) in Asia and Latin America. The accession TOG5681 of African rice, O. glaberrima , presents improved resistance to several biotic and abiotic factors, including nematodes. The aim of this
