SGER: Characterization of an Arabidopsis thaliana UV-B photoreceptor candidate gene

确定紫外线-B光感受器的基因对于了解植物中紫外线-B的反应和全球平流层臭氧消耗的影响是必要的。 利用生物信息学和遗传学方法对拟南芥UV-B光感受器进行了鉴定。将进行额外的遗传分析、光形态发生和基因表达UV-B响应测量以及蛋白质构象变化测定，以检验候选基因确实编码光感受器蛋白的假设。 该项目更广泛的影响包括教育和国际合作部分。教育方面的影响包括支持一名属于代表性不足的少数民族的硕士生。 对UV-B的一种形态反应，即子叶开放，将由阿根廷布宜诺斯艾利斯IVEFA大学的国际合作者测量。

Identification of the gene for a UV-B photoreceptor is necessary for progress in understanding UV-B responses in plants and the effects of global stratospheric ozone depletion. Bioinformatic and genetic approaches were used to identify a candidate Arabidopsis thaliana UV-B photoreceptor. Additional genetic analysis, photomorphogenic and gene expression UV-B response measurements, and protein conformation change assays will be performed to test the hypothesis that the candidate gene indeed encodes the photoreceptor protein. The broader impacts of this project include education and international collaboration components. The education impacts include support of a Masters student who belongs to an underrepresented minority. One morphological response to UV-B, cotyledon opening, will be measured by international collaborators at the IVEFAUniversity of Buenos Aires, Argentina.
