| Plants has faced to environmental stresses during their life cycle and evolved several mechanisms to adapt them in molecular levels. Due these mechanisms, they can response to environment when receiving external signals. The pathways regulating by Abscisic acid, salicylic acid, jasmonic acid and ethylene, as well as ROS, has crucial roles in crosstalk between biotic and abiotic stresses. ABA involved in abiotic stress such as drought, low temperature and osmotic stress. There are common components between ABA and biotic stress signal transduction. Also, epidermal tissues including cuticle and stomata are convergent points of several stresses and act as the first defense site. Transcription factors and kinases are common between stress signal transductions pathways. Protein kinase cascades (MAPK/MPK) are conserved regulators in several processes like differentiation, division, growth and death. They have important roles in response to biotic and abiotic stresses and ROS signal transduction. Ca2+-regulating proteins (e.g. calmodulin), Ca2+- dependent protein kinases, Ca2+- regulating phosphatases and serin/theronin phosphatase act in crosstalk between signal transduction pathways. Several families of transcription factors (such as zinc finger, MYB, MYC, NAC, ERF/AP2) also have key roles in these pathways. |
