Cold acclimatization in tropical region-originated plants involves complex gene expression reprogramming to adapt fluctuating temperatures. However, the molecular mechanisms and networks regulating cold tolerance king grass remain largely unknown. To address this, we established a full-length reference transcriptome of enhance assembly quality performed multiple time-point transcriptomic analyses following treatment at 4°C. Differentially expressed genes (DEGs) transcription factors (TFs) involved stress response were identified analyzed through clustering co-expression network analysis. A total 13,056 DEGs classified into nine clusters via k-means The exhibited three distinct phases: early (before 3 h), middle (6-24 late (48-72 h). Early-responsive enriched glycolipid metabolism photosynthesis, middle-stage carbohydrate metabolism, late-stage stress, osmotic endogenous stimuli responses. Key regulators ICE-CBF-COR signaling module, including 13 positive negative regulators, identified. further revealed mutual regulatory interactions within this highlighting its role adaptation. Our findings provide insights grass, offering genetic basis for modifying regulators. This research contributes broader understanding low-temperature adaptive supports future breeding strategies improved tolerance.

The interaction between trees’ water needs during drought and the signals that appear in their canopies is not fully understood. first visually detectable signs, which we describe as early warning tree canopies, are often noticeable at glance. When these signs become widely apparent, decline already underway. In this study, focus on identifying visible of stress crowns, such very small leaves, premature needle/leaf discolouration abscission, defoliation. We provide guidance recognising initial offer specific examples, comprehensively analyse each signal. Our crowns intense prolonged droughts, confirmed by calculating Standardised Precipitation Evapotranspiration Index (SPEI). findings based 20 years (2004–2024) continuous fieldwork data collection from permanent sample plots Serbia, was conducted part International Co-operative Programme Assessment Monitoring Air Pollution Effects Forests (ICP Forests). also a comprehensive review literature key related to address. This research further motivated observed summer 2024 due extreme climatic events, classify year one hottest recorded Serbia. However, still cannot conclusively determine trees will die back solely signals, some manage withstand severe conditions. Nonetheless, widespread appearance indicators clear significant ecosystem instability, potentially leading individual or larger groups.

The beneficial role of melatonin (MT) as a potent broad-spectrum antioxidant and hormone-like regulator in plant protection against adverse environmental conditions is indisputable. However, the molecular networks underlying its unique scavenging capabilities are still far from understood. Herein, we show ability MT to maintain physiological functions under high light stress (HL) mediated by photoreceptors. Melatonin treatment (50 μM) photoreceptor mutants phyA/B cry1/2 augmented deleterious effects excess (600 μmol m−2 s−1, 24 h), evidenced increased TBARs levels electrolyte leakage, well decreased photosynthetic efficiency, contrast their parental form, Landsberg erecta, which these parameters were significantly improved. reduced resistance was also confirmed analysis transcript accumulation ROS markers enzymatic scavengers. Moreover, increase content exposed HL + contributed accumulation; therefore, effect could not be explained an imbalance production below cytostatic level. We hypothesize that light-sensitive phenotypes may due misregulation stress-related genes targets for action.

Plants select microorganisms from the surrounding bulk soil, which act as a reservoir of microbial diversity and enrich rhizosphere microbiome that helps in growth stress alleviation. use organic compounds are released through root exudates to shape microbiome. These various spectrums technically gear interplay between plants world. Although naturally produce influence world, numerous efforts have been made boost efficiency addition compounds. Despite further crucial investigations, synergistic effects beneficial bacteria combinations reported. In this review, we examine relationship determining plant biotic abiotic We investigate molecular mechanism biochemical responses compounds, discuss modifications alleviation done with help bacteria. then exhibit both components highlight future research directions dwell on how engineering metagenomic approaches could be utilized enhance microbes

An understudied problem in plant heavy metal biology is the effects of acute versus gradual or chronic exposure. The aim present study was to compare growth and physiological responses Rumex hydrolapathum Huds. plants subjected Mn stress treatment controlled conditions. Heavy applied substrate either as one 1.00 g L−1 dose (acute treatment) same four steps increasing amounts within 12 days (gradual treatment). Peroxidase activity actively photosynthesizing leaves used for monitoring induced biochemical changes resulting from treatment. number per significantly increased case with Mn, but this effect not statistically significant Leaf fresh mass decreased both cases due decrease leaf water content, dry biomass affected, no differences between two types treatments. A lower chlorophyll fluorescence parameter Performance Index large under than evident. increase peroxidase by proportional received, had a response comparison Mn. In conclusion, treatment, related induction tolerance are expressed, indicated continuous after each step.

Climate change is a global problem facing all aspects of the agricultural sector. Heat stress due to increasing atmospheric temperature one most common climate impacts on agriculture. has direct effects crop production, along with indirect through associated problems such as drought, salinity, and pathogenic stresses. Approaches reported be effective mitigate heat include nano-management. Nano-agrochemicals nanofertilizers nanopesticides are emerging approaches that have shown promise against stress, particularly biogenic nano-sources. Nanomaterials favorable for production their low toxicity eco-friendly action. This review focuses different stresses production. Nano-management crops under including application nanopesticides, discussed. The potential limitations these nano-agrochemicals reviewed. Potential nanotoxicity need more investigation at local, national, levels, well additional studies into soil, plant, microbial properties processes.
