title: SbRLK1, a receptor-like protein kinase of Sorghum bicolor (L.) Moench that is expressed in mesophyll cells.
abstract: To study the metabolic interactions between mesophyll and bundle-sheath cells of C4 plants, protein kinases possibly involved in the regulatory processes and signal transduction pathways have been cloned and characterized. A receptor-like protein kinase (RLK) cDNA clone from the C4 plant Sorghum bicolor (L.) Moench has been identified. The deduced protein was designated SbRLK1 for receptor-like protein kinase from S. bicolor. The putative cytoplasmic domain of SbRLK1 contains all amino acids that are characteristic of protein kinases. The extracellular domain contains five leucine-rich repeats. The mRNA of the SbRLK1 gene accumulated to much higher levels in mesophyll cells than in the bundle-sheath and was almost undetectable in roots. This expression pattern indicates that SbRLK1 might be involved in the regulation of specific processes in mesophyll cells.
