Summary: The study aimed to investigate the influence of quinoa fractions on the chemical components of wheat flour, dough rheological properties, and baking performance of wheat bread. The microstructure and molecular conformations of quinoa fractions were dependent on the particle size. The highest quinoa fractions addition levels and particle size led to the highest dough viscoelastic moduli, while gradual increase of quinoa fractions determined dough hardness increase and adhesiveness decrease.

Summary: Our study proposes the use of date seeds flour (DSF) as an innovative ingredient for sourdough bread production. We isolated lactic acid bacteria and yeasts from DSF and DSF-derived doughs, selecting strains with rapid adaptation and high ecological fitness. A mixed starter of Leuconostoc mesenteroides, Lactiplantibacillus plantarum, and Saccharomyces cerevisiae strains was formulated and used to create a mature type I sourdough using DSF. The resulting DSF sourdough and bread showed improved functional and sensory properties.

Summary: This study investigated the effects of a benzothiazine (BTh) derivative on wheat under normal and drought conditions. Drought significantly hindered plant growth, altered plant composition, reduced photosynthetic pigments, and affected nutrient uptake. However, seed priming with BTh alleviated water stress, enhancing plant growth, nutrient uptake, and antioxidant production. These findings suggest that BTh seed priming can effectively improve wheat growth and tolerance to drought stress, benefiting growers and meeting food demand.

Summary: The study reveals that the desiccation tolerance in Haematococcus pluvialis is related to the color of the cells, with red cells showing better tolerance. The mechanisms of desiccation tolerance include changes in cell ultra-structure and synthesis of astaxanthin-rich lipid bodies. The processes of acclimation to desiccation under low and high light conditions have overlapping components, such as accumulation of fatty acids, lipid bodies, and astaxanthin. Atmospheric exposure alone can trigger acclimation to desiccation, and photosynthesis powers this process, but high light stress and dehydration are not strictly necessary.

Summary: Parallel local adaptation, when different genetic lineages independently adapt to the same selective environment, was investigated in Arabidopsis arenosa populations from four distinct mountain regions. The study found that the populations exhibited similar adaptive responses to elevation difference, indicating parallel local adaptation. The results highlight the role of divergent selection and provide experimental support for the repeatability of adaptive evolution.

Summary: In plants, senescence is associated with the production of reactive oxygen species (ROS) and lipid peroxidation. However, lipid peroxidation is not solely linked to stress, as it also plays a role in plant development. The major polyunsaturated fatty acid (PUFA) in senescing leaves is linolenic acid, which is sensitive to peroxidation. Lipid catabolism during senescence leads to a decrease in PUFA levels and an increase in short-chain saturated fatty acids.

Summary: The study found that singlet oxygen (O-1(2)) partially regulates light stress signaling in algae and plants, and beta-carotene molecules can quench O-1(2). In the unicellular alga Chlamydomonas reinhardtii, beta-cyclocitral may down-regulate chlorophyll synthesis, but it does not seem to contribute to O-1(2)-mediated high light stress signaling.

Summary: Lichens are unique fungal symbioses that can form a new structure together with photosynthetic partners. The signals involved in the transition from a free-living state to a symbiotic state, called lichenization, and the maintenance of the symbiosis are not well understood. This study synthesizes existing knowledge into a concept of signaling involved in lichenization, including five stages: pre-contact, contact, envelopment, incorporation, and differentiation. Compounds such as fungal lectins and algal cyclic peptides may initiate early contact, while phytohormone signaling, antioxidant protection, and carbon exchange are important throughout all stages.

Summary: Seed quality is crucial for agricultural production, but it is affected by climate change. This study investigated the influence of drought and elevated temperature on key seed quality traits in two genotypes of barley. The results showed that different genotypes of barley had varying responses to drought and temperature stress, with differences in seed size, weight, and vigor. Transcription factors associated with environmental responses and seed dormancy were found to be more abundant in one genotype. Drought significantly reduced seed yield in both genotypes, while elevated temperature only affected seed size. Metabolite profiling revealed differences in metabolic processes between the embryos of the two genotypes, with drought affecting amino acid metabolism in both genotypes. This study could support future breeding efforts to develop lodging and drought-resistant barley varieties without compromising stress resistance and dormancy.

Summary: The photosynthetic apparatus of lichen photobionts, including cyclic electron flow and photoprotection, was studied using chlorophyll fluorescence analysis and near-infrared absorption. Sun species exhibited lower PSI acceptor side limitation and higher flavodiiron-mediated pseudocyclic electron flow compared to shade species. Melanised lichens had lower Y[NA], higher NDH-2-type cyclic flow, and higher non-photochemical quenching, while shade species displayed faster relaxing NPQ. Cyclic electron flow was a prominent feature in all lichens regardless of habitat.

Summary: Heat and drought stresses are important topics in the context of climate change, especially in the Alps. A study found that alpine plants can gradually adapt to heat and achieve maximum tolerance within a week. The antioxidant mechanisms of Primula minima leaves that were heat hardened without or with additional drought stress were investigated. The results showed a weakened low-molecular-weight antioxidant defense but increased activity of antioxidant enzymes, particularly under drought conditions.

Summary: Non-biotic factors, such as water and nutrient availability, play a dominant role in a plant's susceptibility to pathogens. Phenolic compounds in plant tissues are affected by these environmental factors and play a significant role in plant resistance to pests. The study found that nutrient supplementation increased infection rates, while drought stress mainly affected the phenolic profiles in healthy plant parts. Therefore, nutrient supplementation can have negative effects on a plant's resistance to pathogens in nutrient-rich areas.
