Bradfield 101 (Cornell University)

25. Toward Live Elemental Imaging of Anoxia Responses in Plants

Kendal Hirschi

8/6/26, 9:15 AM

Plants under external stimuli

Oral presentation

Oxygen deprivation triggers rapid physiological and biochemical changes in plants, including alterations in ion homeostasis and nutrient redistribution. However, most elemental imaging approaches require harvested tissues and therefore provide only static snapshots of these dynamic processes. We are developing experimental approaches for live synchrotron-based elemental imaging of intact...

10. Exploring plant-environment interactions through multimodal imaging at SSRL

Shuxiao Zhang (SLAC National Laboratory)

8/6/26, 9:45 AM

Plants under external stimuli

Oral presentation

Plants’ responses to external stimuli are highly complex coordinated events that depend on the plant species, genotype, and developmental stage, as well as the strength and duration of the stimuli. In addition, the responses occur on a scale ranging from molecular to organismal level, often resulting in emergent properties that require data with a clear spatial component. Attempts to analyze...

14. Meeting at the Gate: The Role of Root Barriers in Microbe-Induced Resistance

Valeria Castaldi (Yale University)

8/6/26, 10:15 AM

Plants under external stimuli

Oral presentation

Beneficial root–microbe interactions enhance plant growth and stress resilience, including the establishment of a primed immune state known as Induced Systemic Resistance (ISR). Although ISR is typically assayed through leaf responses, its establishment begins in roots, where the cues that gate successful systemic protection remain poorly understood.

Iron (Fe) is a key element for ISR...

43. Foliar application of Nanoscale Iron and Manganese Micronutrients in full life cycle of Soybean (Glycine Max)

Sharif Uddin Ahmed (UNIVERSITY OF TEXAS AT EL PASO)

8/6/26, 10:30 AM

Plants under external stimuli

Oral presentation

Iron (Fe) and manganese (Mn) are essential micronutrients for soybean growth, playing critical roles in chlorophyll biosynthesis, photosynthesis, enzyme activation, and antioxidant defense. However, limited availability of these nutrients in soil often reduces the effectiveness of conventional fertilizers. Foliar application provides a direct and efficient route for nutrient delivery,...
