Sessile plants are permanently confined to their germination place. Some plant species have adapted growth responses (morphological, physiological, biochemical, and molecular adaptations) to deal with the profuse and quick variations in environmental stress, such as drought, through diversity in the context of stress adaptation, higher plants develop sophisticated abiotic stress responses too, such as resistance to drought, to optimize growth under stress (Takahashi et al., 2020). ABA is Differential expression profile of SlCOPT and SlMT genes by Reverse transcription-quantitative PCR in the root and shoot tissues of S. lycopersicum L. subjected to the single and combined stress of Cu and drought inoculated with AGH786 compared with the control. Quantitative **data** represent the means ± standard deviation of three independent experiments and at least three technical replicates each.
