Mily member. Our outcomes indicate that the type-B ARRs have diverged in function, such that some, but not all, can complement the arr1 arr12 mutant. Additionally, our final results indicate that type-B ARR expression profiles inside the plant, in conjunction with posttranscriptional regulation, play significant roles in modulating their contribution to cytokinin signaling.Cytokinins are phytohormones that play critical roles in plant growth and development, which includes regulation of cell division and metabolism, stimulation of chloroplast development, modulation of shoot and root development, and delay of leaf senescence (Mok,This work was supported by the National Study Initiative of your U.S. Department of Agriculture Cooperative State Analysis, Education, and Extension Service (grant no. 200753048323 to G.E.S. and D.E.M.) as well as the National Science Foundation (grants nos.

Cytokinin signal transduction is mediated by a multistep phosphorelay that requires cytokinin receptors, phosphotransfer proteins, and type-B response regulators (Kakimoto, 2003; To and Kieber, 2008; Werner and Schm ling, 2009). These relay the cytokinin signal from the membrane towards the nucleus, exactly where the type-B response regulators induce the transcription of several genes. In Arabidopsis (Arabidopsis thaliana), you’ll find three cytokinin receptors (ARABIDOPSIS HIS KINASE2 [AHK2], AHK3, and AHK4; Inoue et al., 2001; Suzuki et al., 2001; Ueguchi et al.2,5-Furandicarboxylic acid Metabolic Enzyme/Protease , 2001; Yamada et al.PMID:25955218 , 2001; Kakimoto, 2003), five phosphotransfer proteins (ARABIDOPSIS HISCONTAINING PHOSPHOTRANSFER PROTEINS; Hwang and Sheen, 2001; Hutchison et al., 2006), and 11 type-B response regulators (ARABIDOPSIS RESPONSE REGULATORS [ARRs]; Sakai et al., 2001; Mason et al., 2005). Genetic analysis has demonstrated roles for each of these families in cytokinin-mediated processes (M en et al., 2000, 2006; Higuchi et al., 2004; Nishimura et al., 2004; To et al., 2004; Mason et al., 2005; Hutchison et al., 2006; Yokoyama et al., 2007; Argyros et al., 2008). In line with this model, the type-B ARRs play a pivotal part in the early transcriptional response of plants to cytokinin. The type-B ARRs are structurally related, each and every possessing a receiver domain that isPlant Physiology Could 2013, Vol. 162, pp. 21224, 2013 American Society of Plant Biologists.
