I started my PhD study in Prof. Hongliang Zhu’s laboratory at China Agricultural University. Since then, I have focused on the function of the Glycine-rich RNA Binding protein SlRBP1. We found that loss-of-function of SlRBP1 caused dwarf tomato plants with yellow leaves and the fruits of different shades of yellow and orange. We further proved that silencing of SlRBP1 dramatically decreased the translation efficiency of its target mRNAs, nuclear transcripts encoding key photosynthesis-related, chloroplast-targeted proteins. SlRBP1 interacts with the eukaryotic translation initiation factor SleIF4A2 and promotes its association with RNA targets. We propose a model for translational regulation of chloroplast functions by SlRBP1. Currently, I am working as a postdoc to deepen the understanding on the mechanism of SlRBP1 in regulating RNA structures during tomato growth and development.
