Title: Hyo Yeon Lee: Innovator in Zoysiagrass Genetic Transformation
Introduction
Hyo Yeon Lee is a prominent inventor based in Sunchon, South Korea. He has made significant contributions to the field of plant biotechnology, particularly in the genetic transformation of zoysiagrass. With a total of 2 patents, his work focuses on enhancing the efficiency of plant regeneration and transformation methods.
Latest Patents
Hyo Yeon Lee's latest patents include a genetic transformation method for zoysiagrass and a plant regeneration method for mature seed-derived callus in zoysiagrass. The first patent provides an efficient genetic transformation system for zoysiagrass (Steud.). It outlines optimized media compositions and culture conditions that significantly affect calli growth and plant regeneration. The invention emphasizes the importance of callus type and co-cultivation period on transformation efficiency. The best results were achieved by co-cultivating type 3 calli on a 2,4-D-free medium for six days, with the addition of acetosyringone enhancing efficiency. This innovation also includes a bialaphos-resistant zoysiagrass plant, which is beneficial for golf courses and athletic fields, reducing maintenance costs.
The second patent details a method for regenerating fully differentiated higher plants from undifferentiated plant tissues derived from mature seeds. This method involves inducing calli on MS media with specific concentrations of growth regulators. The highest regeneration efficiency is noted when calli are grown on media supplemented with maltose and certain growth hormones. This invention can facilitate the introduction of agronomically important genes into zoysiagrass and related turfgrass species.
