Summary: Carnivorous plants rely on photosynthetic assimilation of carbon dioxide, but have lower photosynthesis rates due to low nitrogen and phosphorus content and the cost of carnivory in their traps. However, nutrient uptake from prey after digestion can increase photosynthesis rate. During prey capture and digestion, carnivorous plants show changes in photosynthesis and respiration rate. Some carnivorous plants are aquatic, with different survival demands from terrestrial plants. The plastid genomes of carnivorous plants resemble those of parasitic and mycoheterotrophic plants.

Summary: Contamination of agricultural soils with heavy metal, such as lead, has negative effects on crop growth and physiological processes like photosynthesis. This study found that lead contamination in soil increased root-weight ratio, root-to-shoot weight ratio, and leaf area of lettuce plants. The concentration of lead was higher in the roots compared to the shoots. Lead contamination also decreased chlorophyll content, net CO2 assimilation rate, and photosynthetic light use efficiency, while increasing leaf respiration rate.

Summary: Kelps play a crucial role as ecosystem engineers in polar rocky shore coastlines. The distribution of kelps is influenced by underwater light climate and temperature. With global temperatures rising, it is predicted that temperate kelp species will expand into the Arctic, aided by accelerating glacial melt. This study investigated the effects of retreating glaciers and rising temperatures on the potential habitat of kelps in Arctic fjords. The results showed that glacial meltwater plumes led to reduced light intensities and changed spectral composition, possibly causing an upward shift of the lower depth limit of kelp. Furthermore, rising temperatures affected the light-use characteristics of two kelp species, potentially leading to changes in species composition.

Summary: Short-term assessment of adverse effects is crucial for populations exposed to high risk of environmental pollution. This study investigates the physiological and morphological changes caused by cadmium, focusing on the susceptibility of different generations of Spirodela polyrhiza fronds to various concentrations of cadmium. The results show that cadmium exposure duration has the most significant impact on chlorophyll content, and frond responsiveness is related to cadmium concentration after 72 hours. The study also reveals that younger fronds exhibit more dynamic responses to cadmium, with molecular, physiological, and anatomical changes, compared to older fronds.

Summary: Light respiration (R-L) is a crucial part of plant carbon balance and an important parameter in photosynthesis models. The Laisk method is commonly used to measure R-L, but a nonsteady-state dynamic assimilation technique (DAT) may provide faster measurements. Two studies were conducted to compare DAT-estimated R-L and parameter C-i* with steady-state estimates in different plant species. The results showed that DAT and steady-state methods yielded similar R-L estimates, with little acclimation to temperature or CO2; however, C-i* was higher when measured with DAT, particularly under different CO2 pre-treatments. Glycine export from photorespiration was proposed as a potential explanation for the differences in C-i*. Nonsteady-state Laisk measurements offer rapid estimation of R-L compared to steady-state methods.

Summary: Alternative electron fluxes such as cyclic electron flux (CEF) and Mehler reaction (Me) play essential roles in efficient photosynthesis by generating additional ATP and protecting photosystems against photoinhibition. Measurements of O-2 exchange rates under varying conditions suggest that different species exhibit varying capacities for Me, with C-4 grasses showing higher Me in shade and low CO2 conditions.

Summary: In Physcomitrium patens, GUCT-domain-containing DEAD-BOX RNA helicases PpRH1 and PpRH2 are localized in the nucleus and are involved in cell and tissue development throughout the moss life cycle. These enzymes are important for various RNA metabolic processes and potentially play roles in plant development and stress responses. Specifically, the nuclear GUCT-containing RNA helicases in P. patens are primarily linked to developmental processes related to photosynthesis activity.

Summary: The Nepenthes hemsleyana, which feeds on faeces, requires less digestive enzymes compared to its close relative Nepenthes rafflesiana that relies on insects, but both species show upregulation of enzyme activity in response to faeces and insect feeding. Contrary to expectations, the final nepenthesin proteolytic activity in the digestive fluid is higher in response to faeces addition than to insect prey, indicating that faeces can mimic arthropod prey triggering the production of digestive enzymes and N. hemsleyana retained capacity for production of them.

Summary: This study revealed that the responses in roots, rather than in shoots, were crucial for greater salt tolerance in quinoa accessions with low epidermal bladder cell (EBC) density. The tolerant accession showed improved root plasma membrane integrity and ion retention in response to salt, along with faster and root-specific oxidative stress responses within 30 minutes of salt application. This demonstrated that differential root signaling events are essential for halophytic quinoa adaptation to salinity, independent of salt sequestration in EBCs.

Summary: In his book, Charles Darwin observed that the response of sundew plants to stimuli is not triggered by water drops but by dissolved chemicals or mechanical stimulation. This study used modern methods to investigate this 150-year-old mystery. The findings showed that sundew plants have a weak response to water drops but significant changes in enzyme activity and digestive enzyme abundance when exposed to other stimuli.

Summary: Many carnivorous plants, including Utricularia reflexa, have a high abundance of alternative oxidase (AOX) in their traps, which are metabolically active and have high respiratory rates. This is in contrast to normal plants, which primarily use the cytochrome c oxidative pathway. The exact role of AOX in carnivorous plant traps remains to be investigated.
