Method for culturing chemical emasculation and seedless fruit plant

Abstract

A method of using herbicide to kill or inhibit the special tissue and organ of the plant, comprising inhibiting the expression of the anti-herbicide gene in the special tissue and organ by using special promoter and antisense technique, then using inner suction conductive selective herbicide to realize the purpose of killing or inhibiting the special tissue and organ of the plant directionally. The product can be used for chemical male-killing, chemical top-killing, seedless watermelon production or prolonging the vegetative growth period according to different design.

Description

technical field

[0001] The invention belongs to the field of plant genetic engineering. In particular, the present invention is a method for targeted killing or inhibition of specific tissues or organs of plants with herbicides. Background technique

[0002] In crop production, sometimes for some special requirements, it is necessary to kill or inhibit specific plant tissues or organs. For example, chemical castration for hybrid seed production is the use of chemical andricides to specifically kill the male tissue of a plant, or the male gametes of a plant. In terms of rice, several chemical andricides such as zinc methyl arsenate and sodium methyl arsenate have been developed, which were once used in China for hybrid seed production by chemical male killing (Hybrid Rice Reproduction, China Agricultural Press, 1999 1st edition, 2010, p. 312). In recent years, rice chemical andricides such as CHAIII (Acta Crops 2001, 27(6): 823-831) have been de...
