報告摘要：
Senescence in plants is one of the most dramatic developmental events we encounter in nature. In annual plants, age-dependent senescence and death is regarded as a life history strategy for a better fitness to determine its temporal niche in a given ecological setting.
We have isolated many key molecular components involved in leaf senescence process, providing molecular insights into aging and senescence control in plants. Nevertheless, to understand a system as complex as senescence, it is essential to study the system in its entirety. We have thus performed comprehensive analyses of Arabidopsis transcriptomes over the entire lifespan of the leaf organ at multi-dimensions. Comparison of the regulatory processes between the growth phase and the aging phase showed that the aging in plant is a highly coordinated process via multi-layered regulatory networks comprising transcription factors and diverse small regulatory RNAs. Thechloroplast transcriptome, but not the mitochondrial transcriptome, showed major changes during leaf aging, with a strongly shared expression pattern of nuclear transcripts encoding chloroplast-targeted proteins. Thus, unlike animal aging, leaf senescence proceeds with tight temporal and distinct inter-organellar coordination of various transcriptomes that would be critical for the highly regulated degeneration and nutrient recycling contributing to plant fitness and productivity.
Leaf senescence is an evolutionarily acquired process and thus the plants evolved in different ecological settings with different evolutionary tracks would show distinct pattern and regulation of senescence in nature. Studies of senescence programs in various natural accessions of Arabidopsis would elucidate how senescence programs have been evolved and diversified. We are now investigating features of leaf senescence among 258 natural accessions in Arabidopsis by examining dark-induced senescence responses through high throughput chlorophyll fluorescence imaging system. I will also present our current progress on establishment of phenotyping system and discuss potential strategies and tactics for phenome-level research toward understanding life history and senescence in plants.
