• Genbank accession number

• Key message
  • Microarray analysis combined with gene ontology analysis revealed that OsPIL15 represses a set of genes involved in auxin pathways and cell wall organization or biogenesis
  • Given the important roles of the auxin pathway and cell wall properties in controlling plant growth, we speculate that OsPIL15 represses seedling growth likely by regulating the auxin pathway and suppressing cell wall organization in etiolated rice seedlings
  • It was found that the expression of OsPIL13 is under the control of circadian rhythms (clock), while the expression of OsPIL15 is negatively regulated by light upon the onset to light exposure of etiolated seedlings
  • OsPIL15-OX seedlings exhibit an exaggerated shorter aboveground part and undeveloped root system relative to wild-type seedlings, suggesting that OsPIL15 represses seedling growth in the dark
  • Additionally, exposure to red light or far-red light relieved growth retardation and promoted seedling elongation in the OsPIL15-OX lines, despite higher levels of OsPIL15 transcripts under red light and far-red light than in the dark
  • Overexpression of OsPIL15, a phytochrome-interacting factor-like protein gene, represses etiolated seedling growth in rice
  • An atypical HLH protein OsLF in rice regulates flowering time and interacts with OsPIL13 and OsPIL15
  • In addition, OsPIL13 and OsPIL15 colocalize with OsPRR1, an ortholog of the Arabidopsis APRR1 gene that controls photoperiodic flowering response through clock function
  • Together, these results suggest that overexpression of OsLF might repress expression of OsGI and Hd1 by competing with OsPRR1 in interacting with OsPIL13 and OsPIL15 and thus induce late flowering
