l h e apple ripening-related cDNA insert of clone pAP4 (C.S. ROSS, M.L. Knighton, M. Lay-Yee [1992] Plant MOI Biol 19: 231238) has previously been shown to have considerable nucleic acid and predicted amino acid sequence similarity to the insert of a tomato ripening-related cDNA clone (pTOM13) that i s known to encode the enzyme I-aminocyclopropane-I-carboxylate (ACC) oxidase (A.J. Hamilton, C....

Mitogen-activated protein kinase (MAPK) is one of the factors of cascade reactions affecting responses to signal pathway of environmental stimuli. Throughout the life of plants, MAPK family members participate in signal transduction pathways and regulate various intracellular physiological and metabolic reactions. To gain insights into regulatory function of MAPK kinase (MAPKK) in Populus trich...

Yeast strains have been widely used as models for eukaryotic microorganisms because of their amenability to biochemical and genetic studies. Recent advances of molecular biological techniques have made this organism an attractive host for functional expression of heterologous genes. Furthermore, structural genes corresponding to various genetic traits have been identified by complementation stu...
