Os01g0286100
The OsPIL15 gene (Os01g0286100), a phytochromeinteracting factor-like protein gene, is a member of the rice Phytochrome‐interacting factors (PIFs) family, in regulating seedling growth.[1]
Contents
Annotated Information
OsPIL15 encodes a basic helix-loop-helix factor localized in the nucleus.Basic helix-loop-helix (bHLH) proteins are the second largest class of plant transcription factors [2]. They comprise two distinct functional regions, a basic region and a helix-loop-helix. The former is required for DNA binding whereas the latter is needed for protein dimerization [3]. Based on DNA-binding ability, the proteins are divided into two groups, 1) DNA-binding bHLH and 2) non-DNA-binding bHLH (HLH) also known as atypical bHLH.
Function
Grain size is a major yield component in rice, and partly controlled by the sizes of the lemma and palea. Molecular mechanisms controlling the sizes of these organs largely remain unknown. In this study, we show that an antagonistic pair of basic helix-loop-helix (bHLH) proteins is involved in determining rice grain length by controlling cell length in the lemma/palea. Overexpression of an atypical bHLH, named POSITIVE REGULATOR OF GRAIN LENGTH 1 (PGL1), in lemma/palea increased grain length and weight in transgenic rice.Proteins with E-values of <4e−12 were selected for analysis; Os12g0610200, Os01g0286100, Os05g0139100, and Os04g0618600. Except for Os04g0618600, all candidates contained amino acids conserved in the basic domain required for binding to DNA. We found expression in the lemma/palea of these candidates. Thus, we chose these four candidates for analysis of interaction with PGL1.
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. 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. 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.These results suggest that light regulation of OsPIL15 expression is probably involved in photomorphogenesis in rice.
