Summary: This study reveals that the decrease in leaf N content delays the induction speeds of net CO2 assimilation, stomatal conductance, and mesophyll conductance upon transition from low to high light in tomato seedlings. The photosynthetic induction kinetics are mainly affected by the induction response of mesophyll conductance rather than stomatal conductance.

Summary: We found that drought stress delays the initiation of photosynthesis and exacerbates the loss of carbon gain under fluctuating light in tomato seedlings. Additionally, drought stress aggravates the over-reduction of photosystem I and suppresses the photoprotection of photosystem I. However, drought stress also enhances relative cyclic electron flow, which partially compensates for restricted CO2 fixation and promotes the photoprotection of photosystem I.

Summary: Plants adjust their photosynthetic processes to adapt to fluctuating light in the environment. The interconnection of short-term and long-term photosynthetic responses presents a challenge in studying plant acclimation to light fluctuations. Mathematical modeling can help differentiate short-term regulatory responses from long-term acclimation responses, integrating physiological processes across different timescales.

Summary: The experiment showed that under fluctuating light conditions, C-4 bioenergy grass species assimilated more carbon than C-3 species, with both types assimilating approximately 16% less carbon than expected based on steady state measurements. There was little diversity in the response to fluctuating light among C-3 species, while differences among the four NADP-ME species in C-4 species were evident. The diversity observed among C-4 species in response to fluctuating light suggests that targeting photosynthetic efficiency could increase C-4 bioenergy grass productivity.

Summary: Mosses can grow under fluctuating light conditions due to the roles of FLVs and CEF in regulating photosynthesis, especially when exposed to temperature stress. The coordination between FLV activity and CEF under fluctuating light and temperature stress is crucial for the photosynthetic acclimation of different moss species. The mosses with different light requirements show distinct FLV activity and CEF levels, indicating a species-specific response to fluctuating light and temperature stress.

Summary: Stomatal morphology plays an important role in regulating leaf gas exchange and photosynthetic efficiency under fluctuating light conditions. Smaller and denser stomata lead to faster stomatal response to light fluctuations but lower intrinsic water use efficiency. Stomatal morphology has less impact on stomatal conductance, and there is minimal correlation between steady-state and non-steady-state stomatal conductance among different genotypes. These findings highlight the significance of stomatal morphology in optimizing photosynthetic efficiency and plant growth under fluctuating light.

Summary: Photosynthesis is a major natural process that converts solar energy into chemical energy, carried out by a wide range of organisms from single cellular bacteria to higher plants. Different organisms possess different types of pigment protein complexes known as photosynthetic light-harvesting antennae, with simpler organisms typically having simple antennae and higher plants having complex systems for more efficient photosynthesis. The complexity of the antenna system is related to the ability of complex organisms to acclimate and adapt to fluctuating environmental conditions.

Summary: This study demonstrated that different ontogenetic stages of leaves in epiphytic orchid Dendrobium officinale utilize different photoprotective mechanisms to deal with fluctuating light. Mature leaves use water-water cycle (WWC) to prevent over-reduction of PSI, while young leaves enhance cyclic electron flow (CEF) around PSI to compensate for the lack of WWC, thus avoiding uncontrolled PSI over-reduction induced by fluctuating light.

Summary: The debate over whether tree leaves in shady environments have higher photosynthetic induction efficiency (IE) than those in sunny environments and how shade tolerance and light environment contribute to photosynthesis dynamics has long been ongoing. In this study, we investigated the photosynthetic responses of six tree species with different shade tolerance levels to simulated changes in light intensity. We found that species with higher relative shade tolerance (RST) had significantly higher IE. The impact of light environment on IE varied among different species, and a trade-off existed between IE and steady-state photosynthetic rates. These findings provide new insights into the adaptation strategy of understory seedlings in sunfleck environments.

Summary: There are differences in growth between tomato plants grown under LED and HPS light. However, it is unclear if breeding specifically for LED supplemental light is worthwhile. In this study, tomato populations were grown under HPS or 95% red and 5% blue LED light. The results showed that LED supplemental lighting led to reduced plant height and side shoot size in all populations. Adult plants under LED had shorter internode lengths, fewer trusses, fruits, and lower yield of ripe fruits per plant compared to HPS. However, including unripe fruits in the yield calculation eliminated the difference between HPS and LED, indicating that plants under LED were compact and slower in development but still produced similar yield.

Summary: Regulatory restrictions on herbicide use have led to the search for alternative control strategies, with fescue species identified for their potential to interfere with weed growth. Among the tested cultivars, Musica and Barpearl were least affected by weed growth over two years, but showed overlap with other cultivars in measured parameters. Future research should focus on different subspecies of fescue and their mechanisms for interfering with weed growth.

Summary: The stress of NaCl affects stomatal behavior and photosynthesis in tomato plants, with osmotic effects decreasing stomatal conductance and increasing stomatal responses to light intensity shifts, while ionic effects reduce photosynthetic capacity, CO2 carboxylation rate, and stomatal conductance. With increasing leaf age, the rates of light-triggered stomatal movement and photosynthetic induction decreased.

Summary: This study found that the severity of intumescence in tomato plants is highly dependent on genotype, with a high heritability. QTLs for intumescence were identified at chromosomal positions, and these QTLs are consistent among different populations. Environmental factors such as light spectrum have no significant influence on intumescence score, but there is a low negative correlation with multiple aspects of plant performance.

Summary: Under natural conditions, fluctuations in irradiance affect the induction of photosynthesis in horticultural crops. We observed significant differences in induction kinetics between crop species, while cultivars within the same species showed smaller variations. Stomatal opening, rather than Rubisco activation kinetics, played a major role in driving the variations in induction time.

Summary: This study investigates the waveform characteristics of ultrasound pulses emitted by plants under drought stress and correlates them with the dimensions of xylem conduits. By using a model that relates the vibrations of a vessel to its dimension and viscoelasticity, the researchers extract the xylem radii from the ultrasound pulse waveforms and show their correlation with optical microscopy. The versatility of the method is demonstrated by applying it to shoots of ten different vascular plant species, and vessel element lengths are further extracted and compared with scanning electron cryomicroscopy for Hydrangea quercifolia. The noninvasive characterization of internal conduit dimensions using ultrasound enables faster and more accurate plant phenotyping and stress detection.

Summary: Understanding photosynthesis in natural light environments requires knowledge of the long-term acclimation as well as the short-term responses and their interactions. This study investigates the effects of light intensity and variability on thylakoid ion transport, which plays a crucial role in dynamic photosynthesis. The findings reveal that daily light intensity shapes photosynthetic capacity and fluctuations in light intensity enhance the accumulation of protective pigment zeaxanthin. The study also uncovers the role of ion transporters in regulating zeaxanthin accumulation and facilitating the transition to lower light intensities.

Summary: The study aimed to investigate the physiological responses and metabolism of tomato seedlings under mild nitrogen and/or water deficit. The combined deficit treatment showed similar effects as single nitrogen deficit, causing lower biomass, leaf area, chlorophyll content, and nitrogen accumulation, but higher nitrogen use efficiency. At the shoot level, both treatments induced higher C/N ratio, activity of nitrate reductase and glutamine synthetase, gene expression related to RuBisCO, and downregulation of specific gene transcripts. Interestingly, the root level responses differed, with combined deficit plants showing similar behavior to water deficit plants, including increased nitrate and proline concentrations, nitrate reductase activity, and upregulation of specific genes. Overall, nitrogen remobilization and osmoregulation strategies play a crucial role in plant adaptation to combined nitrogen and water deficit.
