High-salinity stress is one of the major limiting factors on crop productivity. Physiological strategies against high-salinity stress include generation of reactive oxygen species (ROS), induction of stress-related genes expression, accumulation of abscisic acid (ABA) and up-regulation of

The plant ferredoxin-like protein (PFLP) gene, cloned from sweet peppers predicted as an electron carrier in photosynthesis, shows high homology to the Fd-I sequence of Arabidopsis thaliana, Lycopersicon esculentum, Oryza sativa and Spinacia oleracea. Most of pflp related studies focused on

Ferredoxins (Fds) are small iron-sulfur proteins that mediate electron transfer in a wide range of metabolic reactions. Besides Fds, there is a type of Fd-like proteins designated as FdC, which have conserved elements of Fds, but contain a significant C-terminal extension. So far, only two FdC genes

Ferredoxin-dependent glutamate synthase (EC 1.4.7.1), glutamate oxoglutarate aminotransferase (glutamate synthase) (GOGAT) messenger RNA was extracted from maize (Zea mays L.) leaves and partially purified through oligo(dT)-cellulose chromatography and ultracentrifugation in a sucrose gradient. mRNA

Ferredoxin-NADP(+)-oxidoreductase (FNR) mediates electron transfer between ferredoxin (Fd) and NADP(+); therefore, it is a key enzyme that provides the reducing power used in the Calvin cycle. Other than FNR, nitrite reductase, sulfite reductase, glutamate synthase, and Fd-thioredoxin reductase also

Monodehydroascorbate reductase (MDHAR; EC 1.6.5.4) is a key enzyme in the reactive oxygen species (ROS) detoxification system of plants. The participation of MDHAR in ascorbate (AsA) recycling in the ascorbate-glutathione cycle is important in the acquired tolerance of crop plants to abiotic

A ferredoxin-nitrite reductase (EC 1.7.7.1) cDNA was isolated and sequenced from a lambda gt 11 cDNA library constructed from nitrate-induced greening shoots of rice (Oryza sativa L.) seedlings. The nucleotide sequence of the cDNA clone contains an open reading frame of 1788 nucleotides. There

A ferredoxin-NADP+ reductase (FNR) cDNA was isolated from a lambda gt 11 cDNA library constructed from the roots of nitrate-induced rice (Oryza sativa L. cv. Kinmaze) seedlings. The nucleotide sequence of this clone contains a 1134 nucleotide open reading frame. The N-terminal 62 amino acid stretch

LIR1 (LIGHT-INDUCED RICE1) encodes a 13-kD, chloroplast-targeted protein containing two nearly identical motifs of unknown function. LIR1 is present in the genomes of vascular plants, mosses, liverworts, and algae, but not in cyanobacteria. Using coimmunoprecipitation assays, pull-down assays, and

Ferredoxin-dependent glutamate synthase (Fd-GOGAT, EC 1.4.7.1) plays major roles in photorespiration and primary nitrogen assimilation. However, due to no mutant or knockdown lines of OsFd-GOGAT have been reported in rice (Oryza sativa L.), the contribution of OsFd-GOGAT to rice foliar nitrogen

A genomic clone of the gene encoding a nitrate-inducible ferredoxin-NADP+ oxidoreductase (FNR) from rice (Oryza sativa L.) roots has been isolated and its nucleotide sequence determined. The clone contains 3897 nucleotides of the gene which consists of six exons interrupted by five introns. The

In higher plant plastids, ferredoxin (Fd) is the unique soluble electron carrier protein located in the stroma. Consequently, a wide variety of essential metabolic and signaling processes depend upon reduction by Fd. The currently available plant genomes of Arabidopsis and rice (Oryza sativa)

UNASSIGNED Copper deficiency and excess differentially affect iron homeostasis in rice and overexpression of the Arabidopsis high-affinity copper transporter COPT1 slightly increases endogenous iron concentration in rice grains. Higher plants have developed sophisticated mechanisms to efficiently

We used particle bombardment to cotransform mature seed-derived rice callus (Oryza sativa L., ssp. japonica, cv. Eyi 105) with plasmids containing the linked marker genes gusA and hpt, and the ap1 gene encoding an amphipathic protein previously shown to delay the hypersensitive response induced in
