Summary: In recent years, there has been concern about the harmful effects of environmental pollutants on agricultural output. This study investigated the effectiveness of soil application of bulk silicon, silicon nanoparticles, and Trichoderma metabolites in managing abiotic stress (Cd toxicity) and biotic stress (bacterial wilt) in tomato plants. The results showed that the combination treatment of silicon nanoparticles and Trichoderma metabolites, followed by silicon nanoparticles alone, were the most effective in mitigating Cd toxicity and reducing bacterial wilt disease.

Summary: Several abiotic factors, such as drought, salinity, cold, heat, ultraviolet radiations, reactive oxygen species, trace metals, and soil pH, have a destructive impact on crop yield. These factors induce physiological and biochemical changes in plants and stimulate multi-gene responses, altering the accumulation of primary and secondary metabolites. Metabolomics plays a crucial role in interpreting plant stress tolerance, with primary metabolites serving as osmolytes and osmoprotectants, and secondary metabolites acting as defenses against biotic factors and enhancing resistance against abiotic factors.

Summary: White spruce emits monoterpenes as a defense mechanism against herbivore attack. Drought suppresses the release of monoterpenes, while methyl jasmonate treatment increases their emission. The composition of the emitted blend is altered by stress, with drought increasing the proportion of oxygenated compounds and methyl jasmonate increasing the proportion of induced compounds. The levels of stored monoterpenes and diterpenes are not affected by the treatments. Methyl jasmonate treatment decreases chlorophyll levels, but has no effect on carotenoids, while drought stress has no impact on either pigment class. The expression of the DXS2B gene, involved in the MEP pathway, is increased by methyl jasmonate and decreased by drought.

Summary: Plants face environmental threats during their life cycle, and global warming poses a severe existential threat to them. However, plants adapt by developing strategies coordinated by plant hormones, including ethylene and jasmonates (JAs), to regulate stress responses and produce secondary metabolites. Understanding the mechanisms by which plant hormones and secondary metabolites respond to abiotic stress is crucial for improving plant adaptability to climate change without compromising yield and productivity.

Summary: Glycogen synthase kinase 3 (GSK3) family members are highly conserved protein kinases in mammals and plants, playing a pivotal role in the perception and transduction of diverse signals involved in plant development and stress responses. Recent research has shown that GSK3s are involved in plant adaptation to various stresses and their crosstalk with hormones. Understanding the molecular mechanisms of GSK3s in plant stress responses provides opportunities for developing stress-resilient crops using genetic engineering technology.

Summary: Proficient photosynthetic microalgae/cyanobacteria produce a remarkable amount of various biomolecules. Secondary metabolites (SM) represent high value products for global biotrend application. Production improvement can be achieved by nutritional, environmental, and physiological stress as a first line tools for their stimulation. However, deep understanding and connection of specific stress elucidator are missing. Hence, the present review summarizes recent evidence with an emphasis on the carotenoids, phenolic, and lessdiscussed compounds (glycerol, proline, mycosporins-like amino acids), highlighting the need to expand knowledge in this area using genome-editing tools and omics approaches.

Summary: Plant specialized metabolites (PSMs) are essential in plant adaptation and defense responses, functioning as key components of signaling pathways and serving as antioxidants and chelators. They include nitrogen-containing compounds, terpenoids/isoprenoids, and phenolics, each with their own biosynthetic pathway. Environmental factors and stress-related transcription factors play a role in PSM biosynthesis.

Summary: In this study, an efficient and genetically stable mass multiplication protocol using in vitro culture technology was developed for the endangered orchid Pholidota articulata Lindl. Chitosan supplementation in Gamborg B5 medium resulted in higher frequency plantlet regeneration and improved rooting, shooting, and acclimatizing abilities. Micropropagated plantlets showed genetic uniformity and a higher accumulation capacity of secondary metabolites and antioxidants compared to in vivo plants. The developed in vitro regeneration protocol has significant importance for ex-situ conservation and the harvest of bioactive compounds from P. articulata.

Summary: Paphiopedilum villosum is a horticulturally important orchid that is widely traded for its long shelf-life flowers. The study evaluates the effects of nutrient media and phytohormones on shoot multiplication and seedling proliferation of P. villosum using in vitro techniques. The optimal medium for shoot proliferation and root development was found to be Murashige and Skoog (MS) with the highest response of 70.8% in seedling development. The protocol described in this study is of great importance in controlling the over-exploitation of P. villosum and enhancing its large-scale propagation and conservation.

Summary: This study investigated the interaction between iron excess and phosphorus deficiency in Paspalum densum. The results showed that iron excess decreased phosphorus concentration in roots, while phosphorus deficiency increased iron concentration in leaves. Stomatal limitation was the main cause of decreased photosynthesis due to iron excess. Phosphorus deficiency contributed to higher phosphorus use efficiency and biomass.
