| Title | APICAL SPIKELET ABORTION (ASA) Controls Apical Panicle Development in Rice by Regulating Salicylic Acid Biosynthesis. | |
|
Abstract: Panicle degradation causes severe yield reduction in rice. There are two main types of panicle degradation: apical spikelet abortion and basal degeneration. In this study, we isolated and characterized the apical panicle abortion mutant <i>apical spikelet abortion</i> (<i>asa</i>), which exhibits degeneration and defects in the apical spikelets. This mutant had a pleiotropic phenotype, characterized by reduced plant height, increased tiller number, and decreased pollen fertility. Map-based cloning revealed that <i>OsASA</i> encodes a boric acid channel protein that showed the highest expression in the inflorescence, peduncle, and anther. RNA-seq analysis of the <i>asa</i> mutant vs wild-type (WT) plants revealed that biological processes related to reactive oxygen species (ROS) homeostasis and salicylic acid (SA) metabolism were significantly affected. Furthermore, the <i>asa</i> mutants had an increased SA level and H2O2 accumulation in the young panicles compared to the WT plants. Moreover, the SA level and the expression of <i>OsPAL3</i>, <i>OsPAL4</i>, and <i>OsPAL6</i> genes (related to SA biosynthesis) were significantly increased under boron-deficient conditions in the <i>asa</i> mutant and in <i>OsASA-</i>knockout plants. Collectively, these results suggest that the boron distribution maintained by <i>OsASA</i> is required for normal panicle development in a process that involves modulating ROS homeostasis and SA biosynthesis. |
