NPs-Ca promotes Cd accumulation and enhances Cd tolerance of rapeseed shoots by affecting Cd transfer and Cd fixation in pectin

Calcium l-aspartate nanoparticles modify the root ultrastructure and improve plant yield in Brassica napus L.

“…20 In contrast, it was found that NPs-Ca promoted pectin and lignin formation in shoots and pectin methylesterase activity in Cd-stressed plants. 49 The reason could be that NPs-Ca reduced the activities of the pectin-degrading enzymes PG and β-GAL, which is contrary to our results. XRD analysis indicated no significant peaks at characteristic positions for cellulose I (15.4°, 22.7°) and cellulose II (12.3°, 20.3°, 22.1°) (Fig.…”
