Laboratory of Light Plant Physiology and Genetics
Plant development is regulated by both extrinsic factors, including light, and intrinsic factors such as genetics and phytohormones. We use Arabidopsis seedlings as a model system to study the integration of light- and multiple hormones-mediated signalings, leading to photomorphogenic development. FIN219/JAR1, a jasmonate conjugating enzyme that belongs to a GH3 gene family in Arabidopsis, has been shown to participate in phytochrome A (phyA)-mediated far-red (FR) light signaling and can be induced by auxin and jasmonate. FIN219 as an extragenic suppressor of COP1 can interact with different partners to regulate hypocotyl elongation under far-red light condition. Ectopic expression of different domains of FIN219 in wild-type Columbia shows that the N- and C-terminal domains have an opposite effect on photomorphogenic development. Furthermore, our data reveal that the fin219 mutant affects the levels of COP1 and HY5 specifically under FR, but not other light conditions. COP1 and HY5 interact in the dark, resulting in the degradation of HY5 and leading to a skotomorphogenesis with long hypocotyls and closed cotyledons. In contrast, in the light, COP1 exclusively moves to the cytoplasm and releases HY5 from repression, giving rise to a photomorphogenic development with short hypocotyls, open cotyledons and light responsive gene expression. How the FIN219/JAR1 expression affects the regulation of COP1 and HY5 interaction relationship remains to be elucidated. How jasmonate signaling mediated by FIN219/JAR1 modulates the photomorphogenesis involving COP1 and HY5 regulatory relation is also intriguing. Thus, we plan to use molecular genetics, cell biology and microarray approaches to dissect the functional role of FIN219/JAR1 in the crosstalk between FR light and jasmonate signaling pathways.
FIN219 binds to COP1 protein and its possible function in Arabidopsis. The above picture uses the two-molecule fluorescent protein complementation method (upper left picture) and co-immunoprecipitation method (upper right picture) to prove that FIN219 protein can bind to COP1 protein; the picture below shows FIN219 and COP1 protein when Arabidopsis seedlings respond to light signals Combination and regulation of hypocotyl elongation model diagram.
Functional research on the effects of infrared radiation on plant growth and development
In addition to discussing the function of FIN219 / JAR1 in light and jasmonic acid messages, we also studied how invisible light, such as infrared light, affects the growth and development of Arabidopsis seedlings in the wavelength range of 3-5 μm. The results of previous laboratory studies have shown that Arabidopsis can sense infrared light and activate some signal transmission through the photosynthesis mechanism to inhibit the elongation of hypocotyls and increase biological weight. Recently, we have tried to understand the influence of infrared rays on plant photosynthesis, hoping to obtain more useful information and application value, which can reduce global warming and provide a better life for human beings.
To study the molecular mechanism of light-regulated lycopene content in tomato fruits. In addition to regulating the growth and development of plant seedlings, light messages also affect fruit growth, including the accumulation of lycopene in tomato fruits. We want to understand the molecular regulation mechanism of light-regulated lycopene content in tomato fruits of heat-resistant strains. For this purpose, the laboratory has established tomato transgenic plants that affect the content of lycopene in fruits, and has begun to explore the molecular regulation mechanism. It is hoped that in the near future, lycopene with high economic value and helpful to human health can be obtained. Tomato strain with rich vegetarian content.
