Melatonin mitigates cadmium toxicity by promoting root development, delaying root senescence, and regulating cadmium transport in cotton.

Cd ions are absorbed and transported from the soil by crop roots, which are the first organ to be exposed to Cd. This results in an increase in cadmium ions in crops, significantly affecting crop growth and yield. Exogenous melatonin (MT) can help reduce cadmium (Cd) stress in cotton, but the specific contribution of roots to this process remains unclear.

With potted Hovenia dulcis and Gleditsia sinensis seedlings as test materials, their plant growth, chlorophyll fluorescence characteristics, and active oxygen metabolism under stress of different concentration (0, 0.15%, 0.30%, 0.

[Histological observation on programmed cell death in wheat-leaf rust fungus intreaction].

The biochemical character of PCD in different interaction between wheat and Puccinia recondita f. sp tritici was observed using DNA agarose gel electrophoresis and end labeling in situ (Terminal Deoxynucleotidyl Transferase-mediated dUTP Nick End TUNEL). The DNA ladder, which is the typical character of programmed cell death(PCD), was observed in incompatible combination (cv.
