Abstract

Recently, we reported the genome-wide identification of 107 homeobox genes in rice and classified them into ten distinct subfamilies based upon their domain composition and phylogenetic analysis. Microarray analysis revealed the tissue-specific and overlapping expression profiles of these genes during various stages of floral transition, panicle development and seed set. Several homeobox genes were also found to be differentially expressed under abiotic stress conditions. Based on massively parallel signature sequencing (MPSS) data analysis, we report here that a large number of small RNA signatures are associated with rice homeobox genes, which may be involved in their tissue-specific/developmental regulation and stress responses. The association of a very large number of small RNA signatures suggested an unusually high degree of regulation of homeobox genes by small RNAs during inflorescence development.
