Annotated Information
Function
The rice gene OsSPL14 plays an important role in controlling rice plant architecture as well as yield. OsSPL14 encodes a SQUAMOSA promoter-binding-like (SPL) protein, as a gene that can affect plant architecture[1]. Higher expression of OsSPL14 in the reproductive stage promotes panicle branching and higher grain yield in rice. OsSPL14 controls shoot branching in the vegetative stage and is affected by microRNA excision[2].
Mutation
Jiao et al. demonstrate that a point mutation in OsSPL14 perturbs OsmiR156-directed regulation of OsSPL14, generating an‘ideal’ rice plant with a reduced tiller number, increased lodging resistance and enhanced grain yield[3].
Expression
Luo et al. confirm that OsSPL14 is expressed in the leaf primordia but is excluded from the meristematic cells[4].
Evolution
SPL protein are plant-specific transcription factors containing a highly conserved DNA-binding domain called an SBP-box. The founder members of the SPL family, SBP1 and SBP2, were identified in Antirrhinum majus as proteins that bind to a sequence motif present in the promoter of SQUAMOSA (SQUA), the MADS-box gene which specifies flower meristem identity. SPL genes are widely conserved in both dicots and monocots. In maize, a few SPL genes have been identified, including liguleless1 (LG1), teosinte glume architecture 1 (tga1) and tasselsheath4 (TSH4)[4].
The rice OsSPL14 gene is the closest homolog of the Arabidopsis SPL9 and SPL15 genes and one of the 11 OsmiR156-targeted SPL genes of rice[4].
Knowledge Extension
The SPL genes make up a plant-specific multigene family of transcription factors that can play roles in regulating plant morphology and the decision to flower[1].
