Summary: The rapid increase in population growth under changing climatic conditions causes drought stress, threatening world food security. The identification of physiological and biochemical traits acting as yield-limiting factors in diverse germplasm is pre-requisite for genetic improvement under water-deficit conditions. The major aim of the present study was the identification of drought-tolerant wheat cultivars with a novel source of drought tolerance from local wheat germplasm.

Summary: The stay-green mutation in the soybean hybrid offspring led to slower chlorophyll degradation during leaf natural senescence in the new variety Z1 compared to its parent JD74. Z1 exhibited higher net photosynthetic rate, stomatal conductance, and transpiration rate, along with greater efficiency in maintaining photosystem stability and enhanced photosynthetic efficiency. This was attributed to the mutation in the STAY-GREEN gene, which inhibited chlorophyll degradation and resulted in improved overall photosynthetic performance.

Summary: The study found that antimonite (Sb(III)) is more toxic than antimonate (Sb(V)) to the photosynthetic system of rice plants, leading to lower biomass and impaired physiological parameters. Metabonomic analysis revealed that under Sb stress, more glycosyls were allocated to the synthesis of oligosaccharides to counter excess ROS and strengthen cellular structures.

Summary: The study showed that acid rain stress inhibits photosynthesis in barley plants, leading to a decrease in net photosynthetic rate and chlorophyll content. Non-stomatal factors may also contribute to the reduced photosynthesis under acid rain stress. Different plant species exhibit varying sensitivity to acid rain, and certain parameters can be used to evaluate the sensitivity of plants to acid rain stress.

Summary: The study investigates the effects of foliar application of hydrogen peroxide (H2O2) on tomato plants' photosynthetic metabolism during water scarcity and recovery. The findings suggest that 1 mM H2O2 application increases the maximum rate of RuBisCO carboxylation and contributes to dry mass accumulation in well-watered plants, while 2xH(2)O(2) treatment enhances stress tolerance and improves relative water content in water deficit plants.

Summary: Chlorophyll fluorescence can be used as a proxy for photosynthesis in boreal forests. This study measured the spectral chlorophyll fluorescence in leaves of three dominant evergreen species in the boreal ecosystem and analyzed the correlations with other traits to understand the spatial and temporal variation in chlorophyll fluorescence. The findings suggest that the diversity of species and light environments within an ecosystem generate baseline variation in leaf spectral chlorophyll fluorescence and contrasting seasonal photosynthetic acclimation patterns.

Summary: The aim of this study was to investigate the effects of different phosphorus doses on soybean photosynthesis and carbon partitioning. The results showed that soybean cultivars with higher photosynthetic phosphorus-use efficiency (PPUE) had higher net photosynthetic rate, stomatal conductance, carboxylation rate, electron transport, and triose phosphate use. However, these variables were reduced due to lower phosphorus content in plant tissues under phosphorus deficit. Damage to photosystem II (PSII) only occurred when soybean plants were close to the reproductive stage. The cultivars were efficient in dissipating nonphotochemical energy during phosphorus deficit, but showed higher photochemical efficiency at the reproductive stage with higher phosphorus doses. The soybean cultivar with low PPUE absorbed more phosphorus, resulting in higher starch and sugar contents and greater biomass gain, but lower grain yield compared to the cultivar with the highest PPUE.

Summary: Plants expressing the potato PIP2-7 gene showed improved tolerance to osmotic stress, with higher chlorophyll content, improved stomatal conductance, less electrolyte leakage, and lower malondialdehyde accumulation. PIP plants also exhibited increased expression of antioxidant enzymes and stress-response genes, and had enhanced photochemical efficiency and photosynthetic activity compared to wild type plants. These findings suggest that PIP may be beneficial for developing stress-tolerant crops in the future.

Summary: Turmeric, an important crop in Indian cuisine, produces natural yellow color and curcuminoids which are widely used in medicinal practices. Water deficit and reduced temperature negatively affect turmeric growth, physiological adaptation, and rhizome yield, with decreased curcuminoid content and upregulated expression of curcuminoid-related genes under controlled water-deficit conditions.

Summary: This study evaluated the uptake, translocation, physiological adaptation, metal toxicity, and growth inhibition of rice genotypes grown in acid soil contaminated with iron and aluminum. Different genotypes showed varying levels of tolerance and adaptation to the metal contamination, with some exhibiting enhanced metal accumulation and others maintaining low levels of toxicity through specific gene expressions and biochemical mechanisms. The findings provide insights into potential screening and breeding efforts to increase rice production in Fe/Al-contaminated acid soils.

Summary: In this study, the effects of paclobutrazol (PBZ) and NaCl salt elicitors on water spinach were investigated. The results showed that PBZ treatment reduced the height and shoot length of the plants, while NaCl treatment inhibited shoot length in one cultivar but not in another. PBZ-pretreated plants exposed to NaCl showed reduced Na+ and Ca2+ levels, leading to sustained photosynthetic abilities and plant biomass. Interestingly, NaCl-treated cultivars showed increased levels of soluble sugar, ascorbic acid, and tocopherol.

Summary: Egeria densa, a submerged aquatic plant, is commonly used as a bioindicator for freshwater quality. This study investigated the response of E. densa to salt stress and found that it expresses salt-tolerant genes, accumulates solutes, and undergoes physiological changes. The results suggest that E. densa can tolerate low salt concentrations, but further validation is needed in natural estuarine environments.

Summary: Geographic zone and seasonal variations are major factors affecting the quality and quantity of cultivated medicinal plants, with suitable harvesting time being crucial in Indian pennywort cultivation. Low temperatures during winter can significantly impact the growth and metabolic enrichment of Indian pennywort. This study aimed to determine the optimum temperature for cultivation to achieve superior growth characteristics, physiological adaptations, and secondary metabolite enrichment. Experiments revealed that an ambient air temperature of 25 degrees C resulted in maximum leaf area and overall biomass, while lower temperatures (15 degrees C) inhibited various growth parameters and photosynthetic rates. Furthermore, exposure to 15 degrees C led to changes in pigment parameters, glucose and soluble sugar levels, as well as an increase in certain secondary metabolite concentrations. However, other secondary metabolites showed a significant decrease. Overall, an air temperature of 25 degrees C was found to be optimal for Indian pennywort cultivation to maximize biomass and secondary metabolite production.

Summary: Increasing salinity in agricultural land hampers crop yields, especially for salt-sensitive plants such as rice. A study finds that using an antitranspirant (AT) can enhance salt tolerance in rice by obstructing sodium (Na) transpiration flow. This research evaluates the effects of an AT on Na enrichment and yield in salt-stressed rice plants.

Summary: The objective of this study was to assess the impacts of exogenously-applied foliar MeJA on morphological, physiological, and biochemical traits as well as total andrographolide contents of A. paniculata under water-deficit stress. The results showed that foliar application of 250μM MeJA improved the negative effects of water-deficit stress by enhancing leaf osmotic potential, chlorophyll degradation, photon yield of photosystem II, net photosynthetic rate, and transpiration rate. Especially under water-deficit conditions, 125μM MeJA treatment increased the total andrographolide content and economic benefits.
