Brief bio:

Since I was young, with the guidance of my grandfather, I have developed a strong interest in science. In the China Agricultural University where I start my scientific training mentored by Prof. Junping Gao and Prof. Nan Ma, we found that H2O2 levels in rose (Rosa hybrida) petals follow a circadian rhythm and peak at night, which is consistent with the pattern of respiration rate in petals. The circadian-dependent RhPIF8-RhBBX28 module plays critical roles in H2O2 homeostasis in petals and consequent petal senescence. Additionally, we demonstrated that RhBBX28 directly repressed RhSDH1 expression, and thus the TCA cycle, to an appropriate level to avoid excessive mitochondrial ROS production in rose petals. Thus, our results indicate that the circadian-controlled RhPIF8-RhBBX28 module is a critical player that controls flower senescence by governing mitochondrial ROS homeostasis in rose. Our research provides a better understanding of the regulatory mechanism of ROS homeostasis in non-photosynthetic organs.
