Probing the in-situ volumes of Arabidopsis leaf plastids using 3D confocal and scanning electron microscopy

The paper develops and compares three methods to measure in situ volumes of Arabidopsis leaf plastids using microscopy techniques and mutant lines, finding average volumes of 93 µm³ for mesophyll chloroplasts and 18 µm³ for guard cell plastids.

Dual-sensing genetically encoded fluorescent indicators resolve the spatiotemporal coordination of cytosolic abscisic acid and second messenger dynamics in Arabidopsis

The paper develops dual-sensing fluorescent indicators to analyze ABA and second messenger dynamics in Arabidopsis roots, revealing their spatiotemporal coordination during stress responses.
