[Retracted] Metal Oxide Nanomaterials as Rice Transgenic Carriers

Table 1

Phytotoxic effects of different metal oxide nanomaterials.

nanometer material	Tested plant	Toxic effect
CuO	Rice	CuO can inhibit the growth of rice seedlings
CuO、ZnO	Wheat	Both CuO and ZnO can inhibit the growth of wheat roots, but there are great differences in root morphology, and both can produce genotoxicity to early wheat
CuO、ZnO	Cucumber	CuO and ZnO can inhibit the growth of cucumber
	Pumpkin	can be absorbed by pumpkin and transported to the aboveground part
	Corn	can not affect the phenotypic growth of maize, but can cause a series of physiological indexes of maize to change, and the contents of APX, cat, and HSP70 increase
	Spinach	0.25%can enhance the light cooperation of spinach; Use it to promote its growth
	Corn, peas	can inhibit the germination of maize seeds in the first 24 hours and can significantly inhibit the elongation of maize roots under the treatment of 4‰ concentration
	Corn	200 mg/kg did not affect the growth of maize
	Onion, tobacco	can cause DNA damage in onion and tobacco
	Soybean	SiO 2 and TiO 2 can promote the germination and growth of soybean, improve its root activity, antioxidant capacity, and stress resistance
