okadaic acid/oryza

Okadaic acid (OKA), a potent and specific inhibitor of protein serine/threonine phosphatases 1 and 2A, induced the accumulation of NADH-glutamate synthase (GOGAT) mRNA within 4 h in rice (Oryza sativa L.) cell cultures. In contrast to the transient accumulation of NADH-GOGAT mRNA by NH(4)(+), OKA

Two cDNA clones, pOS-ACO2 and pOS-ACO3, encoding 1-aminocyclopropane-1-carboxylate (ACC) oxidase were isolated from rice seedling cDNA library. pOS-ACO3 is a 1,299 bp full-length clone encoding 321 amino acids (Mr=35.9 kDa), while pOS-ACO2 is 1,072 bp long and is a partial cDNA clone encoding 314

A novel rice (Oryza sativa L.) gene, homologous to a sorghum pathogenesis-related class 10 protein gene, was cloned from a cDNA library prepared from 2-week-old jasmonic acid-treated rice seedling leaves, and named as JIOsPR10 (jasmonate inducible). JIOsPR10 encoded a 160-amino-acid polypeptide with

Inoculation of rice plants (Oryza sativa) with the nonhost pathogen Pseudomonas syringae pv. syringae leads to the activation of defense-related genes and ultimately to induced resistance against the rice blast fungus Pyricularia oryzae. One of the molecular determinants of P. syringae pv. syringae

A rice (Oryza sativa L.) gene for alpha-amylase, alpha Amy3, was strongly and rapidly induced by treatment of suspension-cultured cells with okadaic acid (OA), a potent and specific inhibitor of protein serine/threonine phosphatases 1 and 2A. The massive accumulation of alpha Amy3 mRNA in response

Complementary and genomic DNA clones coding for aldolase C-1, the fourth-type isozyme of aldolase in rice Oryza sativa L., have been characterized. The organization of the gene is quite similar to those encoding rice aldolase C-a and a maize cytoplasmic-type aldolase, in that introns are located in

We report isolation and transcriptional profiling of rice (Oryza sativa L.) mitogen-activated protein kinase (MAPK), OsSIPK (salicylic acid-induced protein kinase). OsSIPK gene is located on chromosome 6 most probably existing as a single copy in the rice genome, and encodes 398 amino acid

We have identified and characterized two rice ascorbate peroxidase (OsAPX1 and OsAPX2) genes against diverse signals known to involve in defense/stress responses, using "2-week-old rice seedling in vitro model system". Oryza sativa ascorbate peroxidase 1 and 2 (OsAPX1/2) share 83% similarity to each

Among the four classes of chitinase, a class II chitinase had not yet been reported for rice. We have isolated and characterized a class II acidic chitinase, Rcht2, from rice (Oryza sativa L. cv. Cheongcheongbyeo). The protein consists of a single polypeptide chain of 261 amino acid residues and
