Identification of Duplicate Loci and Evidence for Post-meiotic Gene Expression in Pollend and relatively brief; however, other tracheophytes possess a more developed gametophyte which often exists as a free-living entity. One would expect such gametophytes to express all enzymes required for an autotropic existence. Indeed, isozyme studies on ferns (Gastony and Gottlieb, 1982) have dem

Extent of Gene Expression at the Gametophytic Phase in Maizesiological processes are those related to respiration, reserve mobilization, nutrient uptake, biosynthesis first of intine and then of pollen tube wall (3). Pollen is also able to respond to environment; this ability is expressed both in physiological interaction with stylar tissues during tube deve
