PLANT SCIENTISTS TO DISCUSS EPIGENETICS AT IOWA STATE, MAY 16-17
AMES, Iowa -- Six leading scientists in the area of epigenetic mechanisms in plants will present their research during the annual Plant Science Lecture Series at Iowa State University. The presentations will be May 16-17 in the Sun Room of the Memorial Union.
Epigenetics is the study of the processes by which genotype (an organism's genetic information) gives rise to phenotype (discernible properties of an organism determined by the interaction of the genotype with the environment). Epigenetic mechanisms are inherited, alternative states of gene expression that occur without a change in DNA sequence. Epigenetics was the subject of a special issue of Science magazine in August 2001.
Each year's program of the Plant Science Lecture Series is devoted to a topic that relates directly to plant breeding science, research and practice. The event is hosted and organized by Iowa State's agronomy department in conjunction with the horticulture, forestry, plant pathology and botany departments.
The program is free and open to the public. Lunches are included. Registration is requested and can be made on the Web at
, or by contacting Mary Lents, agronomy department, (515) 294-3052;
