| The combination of drought, cold and salt factors could occur simultaneously in the field causing a huge loss of crop yields. Hence, the conventional breeding programs that focus on an individual abiotic stress is insufficient to enhance crop productivity in the field. Therefore, the investigation of molecular mechanisms that involve in several abiotic factors is considered as promised tool to improve plant tolerance against simultaneous abiotic stresses. Plants primarily evolved sophisticated regulatory mechanisms to adapt different environmental factors. Here, we reviewed that the effects of drought, salt and cold factors share in inducing cellular osmotic stress. In addition, we showed the crosstalk between the molecular mechanisms that are involved under different abiotic stresses. Overall, we conclude that understanding the physiological responses of plants under simultaneous environmental cues is prerequisite for genetic crop improvement. |
