[AtPep1] 3702 836617 18033818 2008-04-19 11:50 CPR5 has early-life beneficial effects by repressing cell death and insuring normal plant development, but late-life deleterious effects by promoting developmental senescence. 3702 836617 18485217 2008-07-19 10:40 CPR5 is unlikely to be a specific regulator of pathogen response pathways or senescence, but rather functions either in cell wall biogenesis or in multiple cell signaling or transcription response pathways. 3702 836620 18208522 2008-05-24 10:06 The function and metabolism of CDKC2 is reported. 3702 836640 16249327 2007-08-25 12:35 during germination the embryo-specific SDH2-3 is replaced by SDH2-1 or SDH2-2 in mitochondrial complex II 3702 836699 16751349 2007-07-02 15:00 Analysis of BAM1 and BAM2 reveal a cell-cell communication process important for early anther development, including aspects of cell division and differentiation [BAM1] 3702 836701 17417719 2007-09-04 17:34 NFS1 has a role in mediating the assembly of iron-sulfur clusters in mitochondria. 3702 836709 15699063 2005-11-17 12:36 Expression in response to plant growth regulators and abiotic stress in roots and aerial parts as demonstrated by expression of the GUS reporter in A. thaliana. [ACS5] 3702 836724 11404361 2008-03-28 15:31 CHY1 encodes an enzyme acting in valine catabolism; seedlings deficient in CHY1 are sucrose-dependent during germination, probably because accumulation of a valine catabolic intermediate blocks fatty acid beta-oxidation. 3702 836733 15605178 2007-08-25 11:32 The isolation and characterization of the protein, its homology to proteins of other plants, and targeting to the Golgi apparatus. 3702 836737 17092312 2007-07-02 12:44 Results lead to the conclusion that EMB506 and AKRP are involved in crucial and tightly controlled events in plastid differentiation linked to cell differentiation, morphogenesis and organogenesis during the plant life cycle. [AKRP] 3702 836745 15165187 2007-08-25 11:35 a mutant Rad17 pathway is associated with a general deregulation of DNA repair, which seems to be correlated with a deficiency in non-homologous double strand break repair. 37
