“I knew, right then and there, that I wanted to do research in UC Riverside’s graduate program in plant biology,” said Ortiz, now a Ph.D. graduate student in Walling’s lab, where she also researches plant defense mechanisms.
Today, Ortiz and her lab-mates identify and deploy gene-based strategies for insect resistance in plants. Recently, the lab found that transgenic tomatoes that over-express the protein leucyl aminopeptidase A (LAP-A) are more resistant than regular tomatoes to insect feeding.
“We are working on understanding LAP-A’s activity on other tomato proteins that results in plant resistance to insects,” Ortiz said. “One thing I like about doing scientific research is that it makes every day different. I do different kinds of laboratory work, analyze new data, and write. I am also finishing up my courses.”
Ortiz grew up in Panorama City, Calif., and attended James Monroe High School in nearby North Hills. Quiet by nature, she is driven by a determination to succeed. Like many UCR students, she is the first in her family to graduate from college. Her parents, immigrants to the United States from Mexico, regularly attended meetings in her elementary and high school to support her education.
“They understood the importance of a college education,” Ortiz said. “They did not pressure me to have a specific career or get a post-secondary education. They accepted that I would be a science major at UCLA. All they told me was to do what made me happy.” Upon graduating with her bachelor’s degree, she took a year off to work further on her undergraduate research project.
“At UCLA I heard about UCR’s NSF CAMP Bridge to the Doctorate program,” she said. “I attended a Society for the Advancement of Chicanos and Native Americans conference in 2011, and found out from UCR Dean Joseph Childers that I could apply to a graduate program and the CAMP Bridge to the Doctorate program.”
She applied, got accepted, and joined UCR in January 2012.
According to Childers, the dean of the Graduate Division, UCR graduate programs work because of their commitment to producing not only world-class scholars and scientists, but first-class citizens of the world.
“Students like Irma are an important part of UCR’s recipe for producing a diverse, nurturing, but also challenging intellectual environment in which our graduate students train to meet their life goals,” he said. “The point is not simply to attract top students — it is to ensure their success. When we have students like Irma, who take advantage of everything UCR graduate programs have to offer, that success is virtually guaranteed.”
Ortiz’s honors include a National Science Foundation Graduate Research Fellowship “honorable mention,” accorded to meritorious applicants. Because of a fellowship she received from the CAMP Bridge to the Doctorate program for her first two years and a Ford Foundation Fellowship for the next three years, Ortiz can focus on her graduate work without financial burden. She has found useful the workshops the program offers on teaching and mentoring students.
Her family’s history plays a big role in her wanting to continue doing agricultural research.
“My paternal grandfather worked in U.S. fields, such as those in Riverside, through the Bracero program, the guest worker program, in the 1950s,” she said. “He came to the U.S. for months at a time and then would go back to Calera, his hometown in Zacatecas, Mexico. He would return to the U.S. when that labor was needed again.”
Ortiz often keeps in mind for inspiration her family history and roots — when she is in the lab, when she grows tomatoes in the growth chambers and greenhouse, when she treats plant tissues with plant hormones or when she collects, freezes and grinds the tissues — as she works diligently to find a LAP-A protein interactor involved in plant defense signaling. This research would lead, eventually, to making tomatoes more resistant to caterpillar feeding — an important goal that could impact agricultural sustainability in California, the nation and the world.
“I see the difficulties some Mexican families experience when they have a bad season,” she said. “My grandparents worked on agriculture most of their lives. My parents depended heavily on that income. How then could I not work in agriculture?”
