“…Stomatal responses to light have been characterized in angiosperms such as Arabidopsis, C. communis, and V. faba (Zeiger, 1983;Assmann, 1993;Willmer and Fricker, 1996;Roelfsema et al, 2006;Shimazaki et al, 2007). In these plants, stomatal opening is mediated by two light signaling cascades, BL-dependent and photosynthesis-induced responses (Shimazaki et al, 2007;Kollist et al, 2014;Lawson et al, 2014).…”

“…Both mesophyll and guard cells possess photosynthetically active chloroplasts, and their photosynthesis has been suggested to contribute to stomatal opening in leaves. The decrease in the concentration of intercellular CO 2 (Ci) caused by photosynthetic CO 2 fixation or some unidentified mediators and metabolites from mesophyll cells is supposed to elicit stomatal opening, although the exact nature of the events is unclear (Wong et al, 1979;Vavasseur and Raghavendra, 2005;Roelfsema et al, 2006;Mott et al, 2008;Lawson et al, 2014).…”

Light is a major environmental factor required for stomatal opening. Blue light (BL) induces stomatal opening in higher plants as a signal under the photosynthetic active radiation. The stomatal BL response is not present in the fern species of Polypodiopsida. The acquisition of a stomatal BL response might provide competitive advantages in both the uptake of CO 2 and prevention of water loss with the ability to rapidly open and close stomata. We surveyed the stomatal opening in response to strong red light (RL) and weak BL under the RL with gas exchange technique in a diverse selection of plant species from euphyllophytes, including spermatophytes and monilophytes, to lycophytes. We showed the presence of RL-induced stomatal opening in most of these species and found that the BL responses operated in all euphyllophytes except Polypodiopsida. We also confirmed that the stomatal opening in lycophytes, the early vascular plants, is driven by plasma membrane proton-translocating adenosine triphosphatase and K + accumulation in guard cells, which is the same mechanism operating in stomata of angiosperms. These results suggest that the early vascular plants respond to both RL and BL and actively regulate stomatal aperture. We also found three plant species that absolutely require BL for both stomatal opening and photosynthetic CO 2 fixation, including a gymnosperm, C. revoluta, and the ferns Equisetum hyemale and Psilotum nudum.

“…87 For example, it has been shown that chloroplast-containing guard cells in albino sections of variegated leaves do not respond to photosynthetically active radiation, but are sensitive to blue light and CO 2 , bringing into question a direct role of guard cell photosynthesis on red-lightmediated stomatal opening in intact leaves. 35 …”

“…It should be noted that the spider plants had variegated white and green leaves with a white strip down the middle of each leaf blade. Research has shown that stomata in white portions of leaves do not respond to photosynthetically active radiation (Roelfsema et al, 2006). Total leaf area was reported in the results, but the effective spider plant leaf area for photosynthesis was less than the reported total area.…”

ADDITIONAL INDEX WORDS. Chlorophytum, Crassula, interiorscape, passive humidification, transpiration SUMMARY. Plants in the interiorscape have many documented benefits, but their potential for use in conjunction with mechanical heating, ventilation, and air conditioning (HVAC) systems to humidify dry indoor environments requires more study. In this research, evaporation and evapotranspiration rates for a root medium control, variegated spider plants (Chlorophytum comosum), and green jade plants (Crassula argentea) were measured over 24 hours at 25% and 60% relative humidity (RH) and 20°C to generate data for calculation of the leaf surface area and number of plants necessary to influence indoor humidity levels. Evaporation and evapotranspiration rates were higher for all cases at 25% RH compared with 60% RH. At 25% RH during lighted periods, evapotranspiration rates were %15 gÁh L1 for spider plants and 8 gÁh L1 for jade plants. Spider plants transpired during lighted periods due to their C3 photosynthetic pathway, whereas jade plants had greater evapotranspiration rates during dark periods-about 11 gÁh L1 -due to their crassulacean acid metabolism (CAM) photosynthetic pathway. A combination of plants with different photosynthetic pathways (i.e., C3 and CAM combination) could contribute to greater consistency between evapotranspiration rates from day to night for humidification of interior spaces. Using the measured data, calculations indicated that 32,300 cm 2 total spider plant leaf surface area, which is 25 spider plants in 4-inch-diameter pots or fewer, larger plants, could increase the humidity of an interior bedroom from 20% RH to a more comfortable 30% RH under bright interior light conditions.
