Summary: Nanoparticles have a stimulating effect on the photosynthetic apparatus of wheat seedlings, as demonstrated by treating seeds with gold nanoparticles. These nanoparticles penetrate the seeds and induce ultrastructural changes in chloroplasts, leading to increased photosynthesis and stress tolerance.

Summary: This study investigates the molecular mechanisms involved in seed germination under short episodes of heat stress during the wheat grain filling stage. The expression levels of genes related to ABA, GA, and ETH were found to be significantly different under heat stress conditions. The study also highlights the role of temperature in regulating seed germination, with temperatures above 28 degrees Celsius repressing ABA-related gene expression and promoting germination.

Summary: This study found that the accumulation of Cd reduced the low temperature tolerance in barley, leading to the destruction of chloroplast ultrastructure, disturbance of ion homeostasis, and accumulation of reactive oxygen species. The depressed antioxidant enzyme activities and limited plant growth were also observed. The low temperature tolerance in barley was negatively affected by Cd treatment, which highlighted the potential risks of depressed low temperature tolerance caused by Cd pollution in barley.

Summary: Veterinary antibiotics contamination in agroecosystems is a global problem. This study aimed to evaluate the phytotoxic effects of oxytetracycline (OTC) and enrofloxacin (ENR) on wheat. The results showed that high concentrations of OTC and ENR had negative effects on root length, fresh weight, and surface area. Additionally, these antibiotics increased the activity of antioxidant enzymes and ABA levels in wheat seedlings.

Summary: The study found that under cold stress, the levels of ABA and putrescine in melon seedlings increase, enhancing cold tolerance. ABA and putrescine may regulate each other's synthesis, triggering the antioxidant system and reducing membrane lipid peroxidation damage.

Summary: Karrikins (KARs), a class of biostimulants, have been found to play a role in regulating plant growth, development, and stress tolerance. The interaction between KARs, strigolactones (SLs) and abscisic acid (ABA) in plant cold tolerance has been studied. This research has the potential to enhance cold tolerance in tomato production by manipulating the KAR-mediated SL and ABA signaling network.

Summary: Silybum marianum (L.) Gaertn is a well-known medicinal plant, mainly used for silymarin content and oil production. This study focused on analyzing the Sily content in milk thistle ecotypes from different regions under salt stress, and the application of plant growth promoters showed positive effects on alleviating the deleterious effects of salinity stress and improving the quality and quantity parameters of milk thistle. Ecotypic variations with altered achene color patterns proved to be advantageous for higher Sily extraction under salt-stressed conditions.

Summary: The aim of this study was to evaluate the effects of selected microalgae strains on germination ability and physiological processes in winter wheat plants. The results showed that different strains had varying impacts on germination, with some strains improving the process while others performed worse than the control. Microalgae biomass exhibited auxin-like activity, particularly in strain MACC-612, which had the highest level of indole-3-acetic-acid. Foliar spray of microalgae biomass did not significantly affect photosynthesis, but it did alter the composition of secondary metabolites and plant hormones. The application of certain microalgae strains can effectively improve wheat seed germination and modify acclimation processes in a genotype-dependent manner.

Summary: The aim of this study was to genetically characterize hexaploid wheat Triticum aestivum L. Two approaches were used - complete sequencing of chloroplast DNA and PCR-based haplotype analysis of specific gene regions. The results revealed genetic differences between samples collected in different regions, with samples grouped into two main categories: those collected in Armenia, and those collected in Europe. This study identified single nucleotide polymorphisms (SNPs) in various regions of the wheat genome, providing insights into the genetic diversity and evolutionary history of hexaploid wheats.

Summary: This study examined the potential role of endogenous salicylic acid (SA) in regulating endophytic Bacillus subtilis-mediated drought tolerance in wheat. The results showed that B. subtilis 10-4 promoted endogenous SA accumulation and the expression of SA-dependent defense genes, leading to enhanced drought tolerance in wheat seedlings. However, the effects of B. subtilis treatment were abolished by inhibiting SA synthesis, highlighting the importance of SA as a hormone intermediate in triggering the defense responses.

Summary: The study found that higher concentrations of ascorbate were present in leaves, while crowns accumulated more nicotinamide adenine dinucleotide during cold acclimation, deacclimation, and reacclimation in winter wheat. Constant low temperature conditions during cold acclimation led to increased accumulation of ascorbate and glutathione in plant tissues, whereas prolonged higher low temperature conditions had a negative impact on freezing tolerance.

Summary: This study reveals the mechanism of G protein Ga subunit (CsGPA1) in regulating cold tolerance of plants. The results show that CsGPA1 interacts with CsCDL1 and CsCOR413PM2, and positively regulates the expression of brassinolide-related genes. Additionally, CsGPA1 or CsCOR413PM2 inhibition affects Ca (2+) influx at low temperature and subsequently modulates the expression of CsICE-CsCBF.

Summary: The intensive development of nanotechnology has led to the widespread use of nanoparticles in various fields. This study demonstrates that gold nanoparticles can enhance the freezing tolerance of plants, acting as adaptogens. By soaking wheat seeds in solutions of gold nanoparticles, an increase in freezing tolerance of wheat seedlings was observed. The study also establishes a relationship between the increase in freezing tolerance and changes in important indicators for growth, photosynthetic activity, oxidative processes, and sugar accumulation in the seedlings.

Summary: This study demonstrates that gold nanoparticles (GNPs) enhance the freezing tolerance of wheat seedlings by altering their redox status. Among the tested concentrations (5, 10, 20, and 50 µg ml(-1)) of GNPs, a concentration of 20 µg ml(-1) has the most pronounced beneficial effect on the growth and survival rate of the seedlings.
