| Oryza sativa | expression is induced transiently by cold, salt and drought stress | up |
General Information
| General Information | Comment | Organism |
|---|---|---|
| malfunction | overexpression of the gene results in plants with increased size and number of rosette leaves, as well as an increased number of trichome branches | Arabidopsis thaliana |
| malfunction | study of ra mutants reveal that RA3 acts upstream of transcriptional regulator RA1 to regulate maize inflorescence meristem identity and determinacy | Zea mays |
| malfunction | transgenic plants overexpressing AtTPS1 do not show any phenotypic alterations, other than delayed flowering. The AtPS1 overexpression exhibit drought stress tolerance as well as glucose and ABA insensitive phenotypes | Arabidopsis thaliana |
| physiological function | enzyme is a functional synthase and phosphatase as proved by yeast complementation assays | Arabidopsis thaliana |
| physiological function | functional protein as revealed by yeast complementation assay | Arabidopsis thaliana |
| physiological function | trehalose 6-phosphate phosphatase is functional as revealed by yeast complementation assay | Arabidopsis thaliana |
