A rice F-box gene, OsFbx352, is involved in glucose-delayed seed germination in rice
F-box proteins play diverse roles in regulating numerous physiological processes in plants. This study isolated a gene (OsFbx352) from rice encoding an F-box domain protein and characterized its role in seed germination. Expression of OsFbx352 was upregulated by abscisic acid (ABA). The transcripts of OsFbx352 were increased upon imbibition of rice seeds and the increase was markedly suppressed...
متن کاملModeling and phylogenetic analysis of cytosolic ascorbate peroxidase (OsAPX1) from rice reveal signature motifs that may play a role in stress tolerance
Ascorbate peroxidase (APX) is a crucial, haeme-containing enzyme of the ascorbate glutathione cycle that detoxifies reactive oxygen species in plants by catalyzing the conversion of hydrogen peroxide to water using ascorbate as a specific electron donor. Different APX isoforms are present in discrete subcellular compartments in rice and their expression is stress regulated. We revealed the homo...

15 صفحه اولEnhanced seed production under prolonged heat stress conditions in Arabidopsis thaliana plants deficient in cytosolic ascorbate peroxidase 2
Reactive oxygen species play a key role in the response of plants to abiotic stress conditions. Their level is controlled in Arabidopsis thaliana by a large network of genes that includes the H(2)O(2)-scavenging enzymes cytosolic ascorbate peroxidase (APX) 1 and 2. Although the function of APX1 has been established under different growth conditions, genetic evidence for APX2 function, as well a...
