Induction of Cytoplasmic Streaming and Movement of Chloroplast Induced by L-Histidine and its Derivatives in Leaves of Egeria densa

元データ 日本植物生理学会

概要

Rotational cytoplasmic streaming in leaves of Egeria densa was induced by light as well as by L-histidine (L-His). During both treatement with light and with L-His chloroplasts on the periclinal face were dislodged and moved to the anticlinal face where rotational cytoplasmic streaming occurred. The effective concentration of L-His was about 0.01 mM and the effect was almost saturated at O.1 mM. A derivative of L-His, 3-methyl-L-histidine, was slightly less effective than L-His. By contrast, 1-methyl-L-histidine was almost ineffective for induction of streaming, not only in Egeria but also in Vallisneria. Our resutlts are in marked contrast to Fitting's result (1936) that 1-M-L-His is more effective than L-His. In Egeria, 1-methyl-L-His counteracted the stimulative effect of L-His. 1-Methyl-L-His penetrated into leaf cells of Egeria to the same extent as 3-methyl-L-His and to a greater extent than L-His. This observation excludes the possibility that the impermeability of leaves to 1-M-L-His might be responsible for its ineffectiveness. 1-M-L-His did not interfere with photodinesis. Differences in the mechanism of induction of rotational streaming by L-His and by light are discussed.
