e0“Ten-day exposure of nPS-NH 2 induced the strongest phenotypic and physiological inhibition regardless of the exposure dose”

Other claims from this paper (6)
- Observation All PSNP forms entered maize leaves through stomata and accumulated with dose.
- Intervention effect nPS-NH 2 had the highest maize leaf absorption efficiency, 0.208%, 3.92-fold that of nPS.
- Intervention effect nPS-NH 2 absorption efficiency in maize was 2.37-fold that of nPS-COOH.
- Intervention effect The three PSNP forms significantly inhibited biosynthesis of 31 maize membrane structural and signaling lipids.
- Intervention effect The three PSNP forms significantly inhibited associated gene expression in maize leaves.
- Observation Network analysis identified LACS4, GPAT2, LPP2, DGK1 and PLD1 as key genes in maize membrane lipid metabolism.
