The Department of Plant Pathology, Entomology and Microbiology at Iowa State University continued its Fall Seminar Series with an engaging exit seminar from Nicolas Herrera, a Plant Pathology Master’s Student. Approximately thirty faculty, staff, students, and guests attended the lecture on October 4th to learn more about advancements in plant pathology. The seminar provided not only scientific insights but also an opportunity for the department to gather and support a student presenting the culmination of their graduate research.
Hererra focused on finding alternative genetic defense mechanisms in soybean-Phytophthora sojae interactions. More specifically, how DNA demethylation can be used to affect defence gene expression, he also studied how methylation can activate plant immune responses. By understanding DNA demethylation and its impact on defense gene expression, this knowledge could help enhance soybean immunity to Phytophthora sojae, potentially leading to the development of new management strategies.
Audience members appreciated the clarity of Herrera’s presentation and the potential impact of his findings. Ekkachai Khwanbua, a graduate student, enjoyed the seminar and praised Nicolas for “a nice and clear seminar” that made complex concepts accessible and engaging. His comment reflected the feelings of others, who valued the combination of scientific rigor and approachable communication.
The PPEM Fall Seminar Series continues to highlight the complex research being conducted by graduate students in the department. On November 11th, with a seminar presented by Ekkachai Khwanbua, a PhD student in Plant Pathology, who will deliver his exit seminar, “C3 and C4 Crops in a Changing Climate: Physiological and Immune Responses to Rising CO2.”
