11. Plant interactions with soil composition in the extremophile Arabidopsis halleri

Ute Kraemer (Ruhr University Bochum)

8/5/26, 9:45 AM

Fundamental processes in plant nutrient homeostasis

Oral presentation

All ecosystems on land rely on plants to manage nutrient balancing in soils containing variable and largely non-optimal bioavailable levels of essential and non-essential inorganic compounds. Our research aims to understand the molecular and physiological mechanisms of the underlying physiological acclimations and evolutionary adaptations in plants. Arabidopsis halleri is a characteristic...

42. Connecting mineral nutrient homeostasis to fertility and crop yield through synchrotron-based XRF microscopy

JU-CHEN CHIA

8/5/26, 10:15 AM

Fundamental processes in plant nutrient homeostasis

Oral presentation

Advances in imaging technologies have opened new avenues for understanding the physiological basis of plant reproduction. Here, we apply synchrotron-based X-ray fluorescence (XRF) microscopy to investigate the spatial distribution of essential micronutrients, particularly copper (Cu), during reproductive development. Cu deficiency affects approximately 30% of arable land and significantly...

41. A tomato under the beam: Tackling the challenges of fresh-tissue SXRF analysis

Dr Paco ROMERO (Postharvest Physiology and Biotechnology for Food Sustainability Lab. Institute of Agrochemistry and Food Technology (IATA-CSIC), Paterna, Valencia, Spain.)

8/5/26, 10:45 AM

Fundamental processes in plant nutrient homeostasis

Oral presentation

Synchrotron X-ray fluorescence (SXRF) is a powerful technique for investigating element distribution in plant tissues. However, the analysis of fresh, highly hydrated samples remains challenging, as water can attenuate fluorescence signals and dehydration during data acquisition may alter tissue structure and elemental distribution. While substantial anatomical and structural heterogeneity...

34. Toward multimodal synchrotron imaging of pollen wall development in Arabidopsis

Teagen Quilichini (University of Saskatchewan)

8/5/26, 11:00 AM

Fundamental processes in plant nutrient homeostasis

Oral presentation

The spore and pollen wall is among the most chemically complex and resilient biological materials, yet its composition and assembly remain poorly understood. Although genetic studies have identified many enzymes and transport pathways required for pollen wall development, the chemistry of sporopollenin remains debated, and the developmental processes linking biosynthesis, transport, and...

38. Transgenerational effects of water limitation on seed morphology, ionome, and performance under nutrient limiting conditions

Prof. David Mendoza-Cozatl (University of Missouri)

8/5/26, 11:15 AM

Fundamental processes in plant nutrient homeostasis

Oral presentation

One of the most damaging effects of drought on plants and crops is the reduction in yield and quality of seeds. Little is known, however, about the morphological changes happening in seeds at the cellular level when plants experience water limitation. And these changes include seed quality, composition, and offspring performance when the parental lines experience water limitation stress. Here...
