abstract：:We have isolated three alleles of a novel Drosophila clock gene, double-time (dbt). Short- (dbtS) and long-period (dbtL) mutants alter both behavioral rhythmicity and molecular oscillations from previously identified clock genes, period and timeless. A third allele, dbtP, causes pupal lethality and eliminates circadia...

Although it is known that plants absorb and transport K+ through membrane transporters, it remains unclear how these transporters are regulated. Here we show that the protein kinase CIPK23, encoded by the LKS1 gene, regulates K+ uptake under l...
