    Role of mitogen activated protein kinase cascade in combating abiotic stress in plants
    (Springer, 2015) Ara, Hussain; Sinha, Alok Krishna
    Plants being sessile have to counter a plethora of stresses, both biotic and abiotic in order to grow and survive. The ability of plants to perceive these stresses at the cell surface and transduce them to the nucleus for appropriate cellular readjustment is one of the most sophisticated mechanisms they have developed during the process of evolution. Among several cascades helping in signal transduction, mitogen-activated protein kinase (MAPK) cascade is one of the most important cascades that is ubiquitously present in all eukaryotes. This unique protein cascade is also involved in several developmental and vital processes in plants. This is essentially a phosphorelay cascade consisting of three components, a MAPK kinase kinase (MAPKKK/MAP3K/MEKK/MKKK), a MAPK kinase (MAPKK/MAP2K/MEK/MKK), and a MAPK (MPK) connected to each other by the event of phosphorylation. All these components of MAPK cascade are multigene family and are involved in efficient transmission of specific stimuli in response to stress signaling. In the present chapter, we will highlight the involvement of different members of this phosphorelay cascade during abiotic stress in plants.

    Over expression of constitutively active mitogen activated protein kinase kinase 6 enhances tolerance to salt stress in rice
    (Springer, 2013) Kumar, Kundan; Sinha, Alok Krishna
    Salinity is one of the most common abiotic stresses encountered by plants in the environment and transgenic approaches offer new opportunities to improve tolerance. The mitogen activated protein kinase (MAPK) kinase (MKK) is a key component of MAPK cascade that plays important roles in intra and extra cellular signaling in plants. In the present study, a MKK from rice (Oryza sativa), OsMKK6 was functionally characterized in salt stress by transforming its constitutively active form.
