The distribution of RNA and protein in the gametophytes of bracken fern, Pteridium aquilinum is affected by the quality of light in which they are grown. Two‐dimensional gametophytes growing in blue light have a greater amount of RNA and protein than one‐dimensional protonema growing in red light. Fractions rich in nuclei, chloroplasts, mitochondria, ribosomes and soluble supernatants obtained from blue‐light grown gametophytes by differential centrifugation contain greater amounts of RNA and protein than corresponding fractions of red‐light grown plants. Differences in RNA and protein content are detected in some of the fractions within 24 hours after start of the treatment.
