Abstract
Methods of growing plants having modified transpiration rates are provided. Such methods permit more efficient water conservation through regulation of stomatal closure responses. Accordingly, modified plants can be grown in areas which were previously unsuitable for growth and plants which can withstand drought conditions can be grown.
Claims59
A method of creating a transformed plant, which plant in its untransformed state expresses a baseline level of PLD enzyme, said method comprising the steps of:
- recombinantly altering the genome of said plant in an effort to change said baseline level of expression of PLD enzyme;
- and
- testing stomatal closure characteristics of said plant after said genome alteration to determine if said plant has altered stomatal closure characteristics and the relationship between the stomatal closure characteristics and the altered level of PLD enzyme expression, as compared with said baseline level.
A method of growing a transformed plant in a location having unsuitable water and growth conditions for said plant's growth prior to transformation, said method comprising the steps of:
- recombinantly altering the genome of said plant in an effort to change the level of PLD expressed by said plant;
- testing water consumption levels of said plant in order to determine if said genome alteration will permit plant growth in said location;
- and
- planting the progeny of said plant in said location.
A method of growing a transformed plant having modified stomatal closure responses to water availability, which plant in its untransformed state exhibits a baseline stomatal closure response, said method comprising the steps of:
- recombinantly altering the genome of said plant in an effort to change said baseline level of stomatal closure response;
- and
- testing said stomatal closure responses of said transformed plant to determine if said plant has modified stomatal closure responses.
A method of altering water consumption by a plant comprising the step of manipulating the level of PLD enzyme expression.
A transformed plant having an altered level of PLD expression in comparison to wild type plants.
