Plant Biologist Molly Edwards (Get to Know a Scientist!)

The video explores the genetics and evolution of Columbine flowers, focusing on their unique 3D petals called spurs. It discusses the diversity of nectar spurs across different species and the rapid evolution of these traits. The research involves various methodologies, including RNA sequencing and in situ hybridization, to identify genes responsible for spur shapes. The speaker shares personal experiences and the broader implications of the research, emphasizing the joy of scientific discovery and the support of mentors in STEM fields.

What is the primary focus of the research conducted in the Kramer lab at Harvard?

• The impact of climate change on Columbine flowers

• The medicinal properties of Columbine flowers

• The pollination process of Columbine flowers

• The genetics and evolution of Columbine flowers

How do Columbine flowers differ from other flowers in terms of petal structure?

• They have flat, two-dimensional petals

• They have petals that change color with age

• They have 3D petals with a structure called a spur

• They have petals that are thicker than paper

What technique did the researcher use to quantify spur curvature in Columbine flowers?

• Genetic modification experiments

• Field studies in various biomes

• Collaboration with applied mathematicians

• Classical botanical studies

What is the purpose of in situ hybridization in the research on Columbine flowers?

• To create new species of Columbine flowers

• To determine where specific genes are expressed in flower buds

• To identify the pollinators of Columbine flowers

• To measure the length of nectar spurs

What is the significance of creating mutant Columbines in the research?

• To enhance the color of the flowers

• To attract more pollinators

• To study the effects of missing genes on spur shape

• To increase the nectar production

What has the researcher gained from traveling during their graduate studies?

• Knowledge about animal pollinators

• Experience in different climates

• Chances to meet famous scientists

• Opportunities to collect Columbine flowers

What role does the researcher's advisor play in their academic journey?

• Designing the research experiments

• Organizing international conferences
