Plant Plumbing Needed Fifteen Times Less Dye
Two pyridinium probes selectively illuminated xylem at far lower concentration than a common stain.
Summary
Two pyridinium probes selectively illuminated xylem at far lower concentration than a common stain.
IIT Gandhinagar and Regional Centre for Biotechnology researchers tested probes C1 and C3 across three plants. They produced sharper xylem contrast at 25 micromolar versus 375 micromolar for propidium iodide, reducing background and photobleaching; live-tissue adaptation remains future work.
Why it matters
Two pyridinium probes selectively illuminated xylem at far lower concentration than a common stain.
Limits and context
No additional limitation was separately recorded.
