Schematic diagram of BbKst gene structure. A. Genomic organization of total BbKst sequence. P = promoter; E = exon; I = intron, U = UTR region; sequence length of all these regions are mentioned in bp at the respective positions. B. Predicted organizational pattern of BbKst promoter, major sites mentioned within the black box. Position of the transcription start site is shown by an arrow. C. Predicted amino acid residues of BbKst protein, red lined boxes representing LRR repeats and the green box at the C terminal end represents kinase domain.
