A genomic 38 kbp segment on the c1750 cosmid clone containing the cdc2 gene, located in the left arm of chromosome II from Schizosaccharomyces pombe, was sequenced. The segment was found to have five previously known genes, pht1, cdc2, his3, act1 and mei4. Among 11 coding sequences (CDSs) predicted by the gene finding software INTRON.PLOT., four CDSs, pi007, pi010, pi014 and pi016, had considerable similarity to 40S ribosomal protein, glycosyltransferase, cdc2-related protein kinase and alpha-1, 2-mannosyltransferase, respectively. Another unusually huge open reading frame (ORF) (pi011), consisting of 2233 amino acids, existed, having significant homology to alpha-amylase, granule-bound glycogen synthase and the Sz. pombe YS 1110 clone product at the N-terminal, middle and C-terminal regions, respectively. All the predicted 11 CDSs were experimentally analysed by RACE PCR. The sequencing of the RACE products revealed that there were two small overlaps at the 3' untranslated regions (UTRs) between pi004 and pi005 (17 bp) and between pi007 and pi008 (2 bp). The distances between 5' end of the 5'UTR and the putative translation initiation codon varied from 10 to 302 nucleotides (nt) among the nine CDSs successfully analysed by 5'-RACE. The expression level of each CDS on this clone was determined. Among the 16 genes on this clone, the previously determined genes, pht1, cdc2, his3 and act1, were found to be most highly expressed. Finally, cDNAs of all the newly identified genes were detected by RACE, proving the actual expression of these genes. The nucleotide sequence has been submitted to the EMBL database under Accession No. AB004534.

GAMYB is a gibberellin (GA)-regulated activator of hydrolase gene expression in the aleurone layer of germinating cereal grains. Although it is clear that GAMYB expression is regulated by GA, more remains to be understood about how this transcription factor operates within the GA-response pathway. In order to isolate new components from the GA-response pathway, barley aleurone libraries were screened for GAMYB-binding proteins using a recently developed yeast two-hybrid system, which is compatible with the use of transcription factors as baits. We isolated a new member of the emerging Mak-subgroup of cdc2- and MAP kinase-related protein kinases. We have termed this GAMYB-binding protein KGM (for kinase associated with GAMYB). Transient expression of KGM specifically repressed alpha-amylase promoter activity at the level of GAMYB function but a mutation designed to de-stabilise the activation loop of KGM alleviated this repression. We propose that KGM is a negative regulator of GAMYB function in aleurone that may prevent precocious hydrolase gene expression.
