Unraveling Plant Survival Secrets: When Heat Meets Drought

What makes some tomato plants resilient to extreme heat and drought while others struggle to survive, produce healthy pollen, or set fruit? Why do some plants maintain productivity when both stresses occur together?
Our research investigates natural differences among tomato cultivars to understand how plants respond to heat, drought, and combined environmental stress. These stresses can severely affect tomato production, particularly during flowering and fruit set. By studying cultivars that differ in their stress tolerance, we aim to uncover the physiological, biochemical, and molecular mechanisms that help plants maintain growth and reproductive success.
The long-term goal is to identify promising tomato cultivars and genes that can help develop more resilient crops to feed the future.

Research Approaches and Techniques

Students will have opportunities to explore plant biology, physiology, biochemistry, and molecular biology through hands-on research activities, including:

  • Growing tomato plants and comparing their responses to heat and water stress.
  • Measuring plant growth, water status, and photosynthetic performance.
  • Examining flowers, pollen viability, pollen germination, and fruit set.
  • Learning about biochemical responses and gene-expression analysis.
  • Collecting and analyzing data to identify traits associated with stress tolerance.

Depending on project needs and training, students may also gain exposure to molecular techniques used to investigate genes involved in plant stress responses.

Student Role

Undergraduate researchers will help grow and maintain plants, assist with experiments, collect measurements, support laboratory activities, record observations, and analyze research data. Students will work with the research team, learn how to conduct scientific experiments, and contribute to understanding why some tomato varieties are more resilient than others.

Who Should Apply?

Students interested in biology, biochemistry, biotechnology, genetics, molecular biology, or related fields are encouraged to apply. No prior research experience is required—curiosity, motivation, and a willingness to learn matter most.

Why participate in this opportunity?

Have you ever wondered why some plants survive extreme heat and drought while others struggle to grow? That is exactly what we are trying to figure out at UMass Amherst, and I would love for you to join this research! If you’re interested in biology, biochemistry, or biotechnology, this is a chance to take what you learn in the classroom and see how it works in a real research lab. You’ll get to work with tomato plants, investigate how they respond to heat and water stress, explore what happens to pollen and fruit development, and learn how biological processes, genes, and metabolism help plants survive.

You do not need to have previous research experience or know all the techniques already. I am looking for curious students who enjoy asking questions, want to learn new skills, and are excited to discover how science works. You will have the opportunity to gain practical laboratory experience, develop critical-thinking skills, and work alongside a research team.

Most importantly, your work will contribute to research with a real purpose: understanding how we can develop crops that remain productive as our climate changes.

If you are thinking about a future in biotechnology, molecular biology, plant science, or graduate research, this could be a great place to start. Bring your curiosity, your enthusiasm, and your willingness to learn. Let’s discover something new together!

Student qualifications

Students should have an interest in biology, biochemistry, biotechnology, molecular biology, genetics, or related life sciences. A basic understanding of biology and a willingness to learn new scientific techniques help, but no prior research or laboratory experience is required. We welcome motivated undergraduate students who are curious, detail-oriented, reliable, and enthusiastic about hands-on research.

Students should be willing to work with plants, follow experimental protocols, collect and record data carefully, and collaborate with other members of the research team. Experience with laboratory techniques, plant science, or data analysis is a plus but is not required.

The project may involve standing or moving around the laboratory or greenhouse for extended periods, handling plant materials and pots, and performing repetitive measurements. Some activities may take place outdoors, where students may encounter typical seasonal weather conditions. Field activities will be conducted with appropriate safety precautions and supervision. Students should be able to perform the essential tasks of their assigned activities, with reasonable accommodations as needed.

Most importantly, we are looking for students who are eager to ask questions, develop new skills, and discover how science can help address real-world challenges in agriculture and climate resilience.
