Resumen
Introducción y objetivos: La microscopía correlativa multiescala (MCME) combina técnicas microscópicas aplicadas a una misma muestra o región de interés, permitiendo integrar información estructural, funcional y/o composicional a distintos niveles de organización biológica. En botánica su uso ha sido limitado y frecuentemente centrado en estudios ultraestructurales. Este trabajo presenta y evalúa una propuesta de MCME pragmática y reproducible orientada al análisis anatómico integrado mediante continuidad espacial entre escalas. M&M: La MCME se implementó mediante el procesamiento de muestras en un único bloque de parafina del cual se obtuvieron cortes seriados para distintas modalidades microscópicas: estereomicroscopía, microscopía óptica, confocal de barrido láser y electrónica de barrido. La metodología se aplicó a órganos vegetativos y reproductivos, incluyendo anatomía normal y patológica, tejidos glandulares y procesos ontogenéticos en Allium, Eucalyptus, Pilostyles y Adesmia. Resultados: La MCME permitió seguir una misma región tisular a distintas escalas, asegurando correspondencia espacial entre técnicas y facilitando la reconstrucción estructural e interpretación integrada en procesos de desarrollo y diferenciación. Conclusiones: La MCME constituye una herramienta accesible y reproducible que amplía el análisis en anatomía vegetal, con aplicaciones en estudios comparativos, ontogenéticos y funcionales.
Background and aims: Correlative multiscale microscopy (CMM) combines different microscopic techniques applied to the same sample or region of interest, enabling the integration of structural, functional, and/or compositional information across different levels of biological organization. In botany, however, its application has been limited and often focused on ultrastructural studies. This work presents and evaluates a pragmatic and reproducible MCME approach aimed at integrated anatomical analysis through spatial continuity across observational scales. M&M: CMM was implemented by processing samples in a single paraffin block from which serial sections were obtained for different microscopic modalities: stereomicroscopy (SM), light microscopy (LM), confocal laser scanning microscopy (CLSM), and scanning electron microscopy (SEM). The methodology was applied to vegetative and reproductive organs, including normal and pathological anatomy, glandular tissues, and ontogenetic processes in Allium, Eucalyptus, Pilostyles, and Adesmia. Results: CMM allowed the same tissue region to be followed across different observational scales, ensuring spatial correspondence between techniques and enabling structural reconstruction and integrated interpretation of developmental and tissue differentiation processes. The methodological workflow integrates SM for locating regions of interest, LM for histological analysis, CLSM for detecting structural and fluorescent signals, and SEM for micromorphological and topographical characterization. Conclusions: CMM represents an accessible and reproducible tool that expands the interpretative power of microscopy in plant anatomy and is suitable for addressing complex structural questions in comparative, ontogenetic, and functional studies.
