Arabidopsis; DNA damage; fluorescence; gene expression; genes; meristems; mutants; plant development; proteins; ribonucleotide reductase; seedlings; ultraviolet radiation
Abstract:
... The COP9 Signalosome protein complex (CSN) is a pleiotropic regulator of plant development and contains eight-subunits. Six of these subunits contain the PCI motif which mediates specific protein interactions necessary for the integrity of the complex. COP9 complex subunit 7 (CSN7) contains an N-terminal PCI motif followed by a C-terminal extension which is also necessary for CSN function. A yeast ...

Subject:
Arabidopsis thaliana; NADP (coenzyme); developmental stages; genes; hydrogen peroxide; leaves; pathogens; phenotype; plant response; proteins; riboflavin
Abstract:
... Riboflavin mediates many bioprocesses associated with the generation of hydrogen peroxide (H2O2), a cellular signal that regulates defense responses in plants. Although plants can synthesize riboflavin, the levels vary widely in different organs and during different stages of development, indicating that changes in riboflavin levels may have physiological effects. Here, we show that changing ribof ...

Subject:
Arabidopsis thaliana; alleles; gene expression; messenger RNA; mutation; peroxisomes; protein transport; proteins
Abstract:
... Mutations in peroxisome biogenesis proteins (peroxins) can lead to developmental deficiencies in various eukaryotes. PEX14 and PEX13 are peroxins involved in docking cargo-receptor complexes at the peroxisomal membrane, thus aiding in the transport of the cargo into the peroxisomal matrix. Genetic screens have revealed numerous Arabidopsis thaliana peroxins acting in peroxisomal matrix protein imp ...

Abstract:
... To understand the transcriptional responses to flooding stress in roots including hypocotyl of soybean seedlings, genome-wide changes in gene expression were analyzed using a soybean microarray chip containing 42,034 60-mer oligonucleotide probes. More than 6,000 of flooding-responsive genes in the roots including hypocotyl of soybean seedlings were identified. The transcriptional analysis showed ...
