RNA and protein synthesis during in vitro pollen germination and tube elongation in Pinus monticola and other conifers

Pollen germination and tube elongation in Pinus monticola are accompanied by RNA and protein synthesis as shown by the effects of inhibitors such as actinomycin D and cycloheximide, respectively. Pollen grains germinate in the presence of actinomycin D, but further tube elongation is inhibited. This suggests that RNAs needed for germination are already… CONTINUE READING
