摘要: Publisher Summary This chapter focuses on members of two-component systems that have been identified in Arabidopsis . gives the most complete picture currently available way these signaling are represented plants and they function. Histidine kinases response regulators collectively known as “two-component systems.” They confer upon bacteria ability to sense respond environmental stimuli. The first component is a histidine kinase autophosphorylates conserved residue an stimulus. phosphate then transferred aspartic acid second referred “response regulator.” In plants, proteins with homology implicated by hormones ethylene cytokinin sensing changes osmotic pressure responses light regulation pyruvate dehydrogenase. Thus, all components needed for establishing phosphorelay plants. addition specific pathways, contain number whose functions plant unknown.
