“…We do not yet know the identity of the blue-light receptor for the LFR and HFR in A. capillusveneris, although we have recently cloned five cryptochromes (Wada et al, 1997;Kanegae and Wada, 1998) and one NPH1-like phytochrome (Adi phy3) (Wada et al, 1997;Nozue et al, 1998) that may be candidates. All of these genes are expressed in gametophytes.…”

“…This is not to say that PHY diversification is entirely absent outside of seed plants (cf. Wada et al, 1997), but no independently evolving PHY lineages homologous with the major forms found in seed plants have been found in seedless plants (reviewed in Mathews and Sharrock, 1997). Analyses including partial phytochrome sequences (570 bp fragments) in GenBank from additional seed and seedless plants, including more ferns and conifers, gnetalian genera, and a cycad, corroborate this conclusion (not shown; cf.…”

“…However, Adiantum has at least three phytochromes besides phy3 (Wada et al, 1997). To determine whether or not these phytochromes are responsible for red light-induced stomatal opening in Adiantum, we investigated the effect of far-red light on stomatal opening.…”

The Stomata of the Fern Adiantum capillus-veneris Do Not Respond to CO2 in the Dark and Open by Photosynthesis in Guard Cells

The stomata of the fern Adiantum capillus-veneris lack a blue light-specific opening response but open in response to red light. We investigated this light response of Adiantum stomata and found that the light wavelength dependence of stomatal opening matched that of photosynthesis. The simultaneous application of red (2 mmol m 22 s 21 ) and far-red (50 mmol m 22 s 21 ) light synergistically induced stomatal opening, but application of only one of these wavelengths was ineffective. Adiantum stomata did not respond to CO 2 in the dark; the stomata neither opened under a low intercellular CO 2 concentration nor closed under high intercellular CO 2 concentration. Stomata in Arabidopsis (Arabidopsis thaliana), which were used as a control, showed clear sensitivity to CO 2 . In Adiantum, stomatal conductance showed much higher light sensitivity when the light was applied to the lower leaf surface, where stomata exist, than when it was applied to the upper surface. This suggests that guard cells likely sensed the light required for stomatal opening. In the epidermal fragments, red light induced both stomatal opening and K 1 accumulation in guard cells, and both of these responses were inhibited by a photosynthetic inhibitor, 3-(3,4-dichlorophenyl)-1, 1-dimethylurea. The stomatal opening was completely inhibited by CsCl, a K 1 channel blocker. In intact fern leaves, red lightinduced stomatal opening was also suppressed by 3-(3,4-dichlorophenyl)-1,1-dimethylurea. These results indicate that Adiantum stomata lack sensitivity to CO 2 in the dark and that stomatal opening is driven by photosynthetic electron transport in guard cell chloroplasts, probably via K 1 uptake.
