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].
Figure 1. OsSPL14 regulates plant morphology and influences rice grain yield(from reference)[1].
Figure 1 shows that OsSPL14 regulates plant morphology and influences rice grain yield. (a) Classic rice plants are highly tillered with relatively small panicles. (b) In contrast, the new plant type (NPT) architecture is characterized by fewer tillers and more productive panicles. Normally, OsmiR156 induces cleavage of OsSPL14 transcripts, leading to a repression of OsSPL14 activity. However, mutation of an OsmiR156 binding site within OsSPL14 increases the levels of OsSPL14 and results in rice plants with fewer tillers but more productive panicles and consequently higher grain yields[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].
