Abstract
The present invention provide methods of imparting stress tolerance, characterized in that an expression amount of at least one stress defense gene is increased compared with a non-transformant by transforming the plant with an exogenous spermidine synthase (SPDS) gene, an exogenous S-adenosylmethionine decarboxylase (SAMDC) gene, an exogenous arginine decarboxylase (ADC) gene, an ornithine decarboxylase (ODC) gene and/or a spermine synthase (SPMS) gene under the control of a promoter capable of functioning in the plant.
Claims19
A method of inducing an expression of at least two stress defense genes in a plant, wherein an expression amount of at least one stress defense gene is increased compared with a non-transformant by transforming the plant with an exogenous spermidine synthase (SPDS) gene, an exogenous S-adenosylmethionine decarboxylase (SAMDC) gene, an exogenous arginine decarboxylase (ADC) gene, an ornithine decarboxylase (ODC) gene and/or a spermine synthase (SPMS) gene under the control of a promoter capable of functioning in the plant.
A method of imparting stress defense effects to a plant wherein expression amounts of at least two stress defense genes are increased compared with a non-transformant by transforming the plant with an exogenous spermidine synthase (SPDS) gene, an exogenous S-adenosylmethionine decarboxylase (SAMDC) gene, an exogenous arginine (ADC) decarboxylase gene, an ornithine decarboxylase (ODC) gene and/or a spermine synthase (SPMS) gene under the control of a promoter capable of functioning in the plant.
A method of imparting stress defense effects to a plant wherein expression amounts of at least two stress defense genes are increased compared with a non-transformant by transforming the plant with an exogenous spermidine synthase (SPDS) gene, an exogenous S-adenosylmethionine decarboxylase (SAMDC) gene, an exogenous arginine (ADC) decarboxylase gene, an ornithine decarboxylase (ODC) gene and/or a spermine synthase (SPMS) gene under the control of a promoter capable of functioning in the plant, and a transformed plant in which expression levels of the stress defense genes have been increased compared with a non-transformed plant (wild type) is selected
A method of enhancing productivity of a plant wherein expression amounts of at least two stress defense genes are increased compared with a non-transformant by transforming the plant with an exogenous spermidine synthase (SPDS) gene, an exogenous S-adenosylmethionine decarboxylase (SAMDC) gene, an exogenous arginine (ADC) decarboxylase gene, an ornithine decarboxylase (ODC) gene and/or a spermine synthase (SPMS) gene under the control of a promoter capable of functioning in the plant.
A method of enhancing stress tolerance in a plant wherein expression amounts of at least two stress defense genes are increased compared with a non-transformant by transforming the plant with an exogenous spermidine synthase (SPDS) gene, an exogenous S-adenosylmethionine decarboxylase (SAMDC) gene, an exogenous arginine (ADC) decarboxylase gene, an ornithine decarboxylase (ODC) gene and/or a spermine synthase (SPMS) gene under the control of a promoter capable of functioning in the plant.
