jacalin/oryza sativa

Lectin plays an important role in defense signaling in plants. A few genes of this family have been cloned. Here we report on a mannose-specific jacalin-related lectin in rice. Using sequence information of wheat gene VER2, which we had previously cloned, we were able to amplify a cDNA of OsJAC1

A novel plant lectin was isolated from salt-stressed rice (Oryza sativa L.) plants and partially characterized. The lectin occurs as a natural mixture of two closely related isoforms consisting of two identical non-covalently linked subunits of 15 kDa. Both isoforms are best inhibited by mannose and

Treatment of whole plants with jasmonic acid methyl ester induces lectin activity in leaves of Oryza sativa, Hordeum vulgare, Triticum vulgare, Secale cereale and Zea mays. Purification and characterization of the lectins revealed that they all have a very similar molecular structure and

The genome of rice blast fungus (Magnaporthe oryzae) encodes 15 glycoside hydrolase 18 family chitinases. In this study, we characterized the function of an M. oryzae extracellular chitinase, MoChi1, and its interaction with a host protein, OsMBL1, a jacalin-related Mannose-Binding

BACKGROUND Brown planthopper (BPH, Nilaparvata lugens Stål), is the most destructive phloem-feeding insect pest of rice (Oryza sativa). The BPH-resistance gene BPH15 has been proved to be effective in controlling the pest and widely applied in rice breeding programs. Nevertheless, molecular

As one of the most destructive and widespread disease of rice, Magnaporthe oryzae (also called Magnaporthe grisea) has a significant negative impact on rice production. Therefore, it is still in high demand to develop extremely sensitive and accurate methods for the early diagnosis of Magnaporthe

The Oryza sativa lectin, abbreviated Orysata, is a mannose-specific, jacalin-related lectin expressed in rice plants after exposure to certain stress conditions. Expression of a fusion construct containing the rice lectin sequence linked to enhanced green fluorescent protein in Bright Yellow 2
