Sensor plant and method for identifying stressors in crops based on characteristics of sensor plants

A system for detecting plant stressors, comprising a computer system configured to:

• (a) access one or more spectral images of one or more sensor plants in an agricultural environment, wherein:
• (i) the one or more sensor plants comprises at least one plant that has been genetically engineered, wherein the at least one plant comprises one or more promoter-reporter pairs;
• (ii) the one or more promoter-reporter pairs comprises a promoter gene sequence configured to activate in the presence of a corresponding stressor and a reporter gene sequence configured to generate a detectable signal when the promoter gene sequence is active;
• and
• (iii) a first promoter-reporter pair of the plurality is configured to generate a first detectable signal indicating a presence of a first stressor;
• (b) process the one or more spectral images to detect the first detectable signal;
• (c) determine a presence of at least one of the first stressor and the second stressor based on detection of a corresponding detectable signal;
• and
• (d) determine a magnitude of a detected stressor based on an intensity of the corresponding detectable signal.
