| Title | <i>Histone Deacetylase 701 (HDT701)</i> Induces Flowering in Rice by Modulating Expression of <i>OsIDS1</i>. | |
|
Abstract: Rice is a facultative short-day (SD) plant in which flowering is induced under SD conditions or by other environmental factors and internal genetic programs. Overexpression of <i>Histone Deacetylase 701</i> (<i>HDT701</i>) accelerates flowering in hybrid rice. In this study, mutants defective in <i>HDT701</i> flowered late under both SD and long-day conditions. Expression levels of florigens <i>heading date 3a</i> (<i>Hd3a</i>) and <i>Rice Flowering Locus T1</i> (<i>RFT1</i>), and their immediate upstream floral activator <i>Early heading date 1</i> (<i>Ehd1</i>), were significantly decreased in the <i>HDT701</i> mutants, indicating that <i>HDT701</i> functions upstream of <i>Ehd1</i> in controlling flowering time. Transcript levels of <i>OsINDETERMINATE SPIKELET 1</i> (<i>OsIDS1</i>), an upstream repressor of <i>Ehd1</i>, were significantly increased in the mutants while those of <i>OsGI</i> and <i>Hd1</i> were reduced. Chromatin-immunoprecipitation assays revealed that HDT701 directly binds to the promoter region of <i>OsIDS1</i>. These results suggest that HDT701 induces flowering by suppressing <i>OsIDS1.</i> |
