Diverse panicle architecture results from various combinations of Prl5/GA20ox4 and Pbl6/APO1 alleles

Purpose: To confirm the effects of Prl5 and Pbl6 (APO1) on panicle length at the gene expression level, we performed RNA-seq analysis to compare the expression patterns of these genes in young panicles of the near isogenic lines (NILs). Results: Gene Ontology (GO) representation analysis indicated that the biological functions of the two genes are quite different. Conclusions: RNA-seq analysis revealed that these two genes independently regulate panicle length at the level of gene expression. mRNA profiles of 2-mm stage young panicles of Koshihikari, NIL-Prl5ST-1, NIL-Pbl6ST-1, and NIL-Prl5ST-1+Pbl6ST-1
