A short-term (one-hour) irradiation stress was applied to metabolically active thalli and parameters related to photosynthesis at various recovery periods after treatment was examined through complementary in vivo chlorophyll fluorescence techniques (OJIP transients and quenching analysis), 77 K fluorescence emission spectra and assimilation pigment measurements. In both species, considerable but reversible photoinhibition of photosystem II was observed following sunlight and VIS radiation exposure, as evidenced by a significant decrease in F_V/F_M and increased K and J steps of the OJIP curves; albeit photodamage resulting from sunlight was more pronounced. Although UV-A1 had negligible inhibitory effect, it stimulated pigment synthesis in C. aculeata and enhanced photochemical energy utilization in C. uncialis. The two species revealed different strategies to cope with excess light energy; namely, C. aculeata relied on enhanced non-photochemical quenching (NPQ) and redistribution of excitation energy toward PSI, whereas C. uncialis preserved a more efficient donor site of PSII (higher F_V/F₀). Overall, VIS radiation was identified as the primary factor impairing PSII, posing a substantially greater threat than UV-A1.

Mesophyll conductance, a key determinant of photosynthetic rate, is strongly impacted by anatomical traits, yet the specific structural correlates of mesophyll conductance under varying light spectra remain incompletely understood. We investigated how varying red (R) and blue (B) light ratios affected leaf anatomical traits and how these traits were associated with changes in mesophyll conductance and photosynthetic rate in cucumber. The results demonstrated that plants grown under monochromatic red light exhibited impaired photosynthetic performance, together with reductions in leaf thickness, leaf mass per area, stomatal density, and chloroplast exposure to the intercellular airspace. These anatomical characteristics were associated with lower mesophyll conductance, consistent with greater resistance to CO₂ diffusion across both gas- and liquid- phases. In contrast, blue-enriched spectra (25B, 75B, 100B) were associated with greater chloroplast exposure to the intercellular airspace and larger intercellular airspace, which coincided with higher mesophyll conductance and photosynthetic rate. The 75B treatment showed the highest photosynthetic performance, coinciding with a combination of favorable mesophyll and chloroplast anatomical characteristics. Analysis of modeled diffusion resistance indicated that cell wall and chloroplast stroma resistances accounted for major components of the modeled resistance to CO₂ diffusion and varied with corresponding anatomical features. Quantitative limitation analysis confirmed that mesophyll limitation was the predominant constraint under all light regimes. Our findings demonstrate that light quality associated anatomical variation is closely linked to mesophyll conductance and internal CO₂ diffusion, providing physiological insight into how spectral composition influences photosynthetic performance in controlled-environment agriculture.</p>","PeriodicalId":20130,"journal":{"name":"Photosynthesis Research","volume":"164 6","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149216566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combined use of α-DDM and digitonin for direct thylakoid membrane solubilization, coupled with optimized sucrose density gradient conditions, enabled the successful isolation of PSII-LHCII supercomplexes with improved antenna retention and reduced PSI co-isolation. The optimized conditions are further successfully applied to two shade-adapted plant species, Epipremnum aureum (E. aureum) and Hygrophila difformis (H. difformis), supporting the applicability of this approach beyond F. albivenis.

Measurements of maximum turnover rates in model species of green algae and diatoms over a range of environmental conditions revealed that the rates vary from 150 to 600 s^- 1 per PSII. These rates correspond to the minimum turnover times of 1.6 to 7 ms. Decreases in turnover rates are driven by low-light photoacclimation and nutrient limitation. In natural populations of near-surface phytoplankton in tropical and subtropical regions, the maximum turnover rates may reach approximately 800 s^- 1, reflecting photoacclimation to high solar irradiance. In contrast, in cold polar waters, especially under severe nitrogen limitation, the turnover rates decline to 80 to 140 s^- 1, highlighting a strong temperature and nutrient dependence.

Studying the excitation dynamics of these RCs helps better understand the physical mechanisms underlying their organization and function, which may be useful in the creating of their artificial analogs. Using femtosecond differential absorption spectroscopy, we studied the early-time dynamics of excited states of bacteriochlorophyll B_A and B_B monomers in mutant RCs from purple bacteria Rhodobacter (Rb.) sphaeroides, which lack the bacteriochlorophyll P dimer due to the replacement of valine with arginine at residue L157. Charge separation is absent in these RCs, which cardinally simplifies the study of chromophore excitation dynamics. We found that upon excitation of RCs in the Q_y absorption band of B formed by the closely lying bands of B_A and B_B, the spectrum ΔA(light - dark) rapidly shifts along the wavelength scale, and the direction and magnitude of this shift depend on the pump wavelength λ_pump and temperature T. At λ_pump = 780-785 nm, B_A is mainly excited, and the spectrum ΔA shifts to the red side in ~ 300 fs by ~ 2.5 nm at 77 K and by ~ 1.5 nm at 295 K.
