Plants such as Arabidopsis are shade-intolerant. This means that direct light is an essential resource for their growth. When they compete with adjacent plants for light, a reduction in the red/far-red(R/FR) ratio can trigger a series of responses known as the shade avoidance syndrome (SAS). SAS is a strategy of major adaptive significance to plants growing in natural ecosystems. It is a phenomenon that can significantly impact yield in high-density planting, typical of modern agriculture. Our lab is interested in understanding the physiological and molecular photobiology of SAS using genetic, biochemical and cellular approaches.

The plant module I designed for BIOS will introduce the basic principles of plant photobiology and showcase four related experiment types: plant growth, gDNA extraction from plant tissue, genotyping of different mutants, and transformation in Agrobacterium. The final series of experiments will be authentic so participating students can actually identify the genotypes of unknown photomutants. We hope this training opportunity will enhance your interest in plant biology and attract you to join our lab. Hope to see you!

植物和人类在3亿年前共享同一个祖先,他们有着相同的DNA编码和近似的细胞机构。在人类分离出去之后,植物获取了光合作用的能力,这种将光能转化为化学能的能力使得植物成为了陆生系统的生产者,为人类提供了必需的食品、健康、住所、衣服和快乐。为什么要研究植物?到2020年,世界人口有望增长到75亿,全球范围内,每年超过10亿人处于长期慢性饥饿状态,由于缺铁,每年超过20亿人患有慢性贫血病。面对这些问题,植物学家不断尝试着培育更加耐旱、抗虫、更加有营养的新型作物。同时,植物是新型药品的来源,也为造纸和纺织提供纤维原料。(更多的信息…)
