My Journey from Horticulture to Plant Biology

Keywords: photoperiodism, florigen, flowering, grafting, gibberellin, abscisic acid, water stress, Autobiography Abstract The author describes the circumstances and opportunities that led him to higher education and to pursue a research career in plant biology. He acknowledges the important roles a few individuals played in guiding him in his career. His early work on flowering was followed by studies on the physiological roles and the metabolism of gibberellins and abscisic acid. He describes how collaborations and technical developments advanced his research from measuring hormones by bioassay to their identification and quantification by mass spectrometry and cloning of hormone biosynthetic genes
