OsMAPKKKε regulates apical spikelet development by adjusting Reactive Oxygen Species accumulates in Oryza sativa
Rice panicle abortion can significantly impact rice yield and food security. Recent research has revealed that panicle abortion is influenced by environmental factors as well as regulated by specific genes. Here we report a novel panicle apical abortion 4 (paa4) mutant with semi-dwarf and panicle apical abortion phenotype, and its abortion occurs when the panicle length is approximately 7 cm. Map-based cloning has identified that PAA4 encodes a Mitogen-activated Protein Kinase Kinase Kinase ε (OsMAPKKKε) protein, and a substitution of G to A in exon 19 of OsMAPKKKε that leads to panicle apical abortion. PAA4 has a higher expression in the spikelet although which expressed in all organs of rice. During panicle growth, excessive Reactive Oxygen Species (ROS) accumulate in the apical panicle of paa4, eventually inducing programmed cell death (PCD). Transcriptome sequencing indicates that PAA4 plays a role in both the generation and elimination of ROS. Therefore, PAA4 might be involved in the balance of ROS at the apical panicle and then affects spikelet development in Oryza sativa.
期刊介绍:
Plant Science will publish in the minimum of time, research manuscripts as well as commissioned reviews and commentaries recommended by its referees in all areas of experimental plant biology with emphasis in the broad areas of genomics, proteomics, biochemistry (including enzymology), physiology, cell biology, development, genetics, functional plant breeding, systems biology and the interaction of plants with the environment.
Manuscripts for full consideration should be written concisely and essentially as a final report. The main criterion for publication is that the manuscript must contain original and significant insights that lead to a better understanding of fundamental plant biology. Papers centering on plant cell culture should be of interest to a wide audience and methods employed result in a substantial improvement over existing established techniques and approaches. Methods papers are welcome only when the technique(s) described is novel or provides a major advancement of established protocols.
