| Title: Fine mapping and candidate gene analysis of dense and erect panicle 3 , DEP3 , which confers high grain yield in rice ( Oryza sativa L ) .
| | Author: Qiao Y Piao R Shi J Lee SI Jiang W Kim BK Lee J Han L Ma W Koh HJ | | Journal: Theor Appl Genet Citation: V : 122 P : 1439-49 Year: 2011 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub21318372 Accession (PMID): 21318372 | | Abstract: Architecture of the rice inflorescence , which is determined mainly by the morphology , number and length of primary and secondary inflorescence branches , is an important agronomical trait .
In the current study , we characterized a novel dense and erect panicle ( EP ) mutant , dep3 , derived from the Oryza sativa ssp . japonica cultivar Hwacheong treated with N-methyl-N-nitrosourea .
The panicle of the dep3 mutant remained erect from flowering to full maturation , whereas the panicle of the wild type plant began to droop after flowering .
The dep3 mutation also regulated other panicle characteristics , including panicle length , grain shape and grain number per panicle .
Anatomical observations revealed that the dep3 mutant had more small vascular bundles and a thicker culm than wild type plants , explaining the EP phenotype .
Genetic analysis indicated that the phenotype with the dense and EP was controlled by a single recessive gene , termed dep3 .
The DEP3 gene was identified as the candidate via a map-based cloning approach and was predicted to encode a patatin-like phospholipase A2 ( PLA2 ) superfamily domain-containing protein .
The mutant allele gene carried a 408 bp genomic deletion within LOC_Os06g46350 , which included the last 47 bp coding region of the third exon and the first 361 bp of the 3-untranslated region .
Taken together , our results indicated that the patatin-like PLA2 might play a significant role in the formation of vascular bundles , and that the dep3 mutant may provide another EP resource for rice breeding programs .
