Low temperature is a critical environmental stress factor that restricts crop growth and geographical distribution, significantly impacting quality yield. When plants are exposed to low temperatures, series of changes occur in their external morphology internal physiological biochemical metabolism. This article comprehensively reviews the alterations regulatory mechanisms indices, such as membrane system stability, redox system, fatty acid content, photosynthesis, osmoregulatory substances, response low-temperature plants. Furthermore, we summarize recent research on signal transduction pathways, phytohormones, epigenetic modifications, other molecular mediating temperatures higher In addition, outline cultivation practices improve plant cold resistance highlight cold-related genes used breeding. Last, discuss future directions, potential application prospects breeding, significant breakthroughs mechanisms.

Low root-zone temperatures (RZTs) are known to cause various physiological changes in plants, which ultimately result reduced overall plant growth and productivity. However, the effects of temperature on below-ground parts remain largely unknown; a notable gap exists understanding low RZTs plants. Therefore, we explored impact short-term cooling (RZTC) growth, responses, amino acid levels Taraxacum coreanum hydroponic systems. We also investigated monoamine oxidase (MAO) inhibitory activity T. leaves roots following RZTC treatment. were exposed low-temperature nutrient solutions over 5 days cool root zone at 53 after sowing. treatments included gradual (GC), with gradually decreasing from 15 °C for days, rapid (RC), days. caused decrease total content, except glutamic proline leaves. In roots, RC treatment significantly increased glutamine, glutamine exhibiting most significant changes, thus increasing acids. MAO inhibition assays indicated improved both treatments, enhancing greater extent than GC exposing can high content rates against MAO.

Cold stress declines the quality and yield of tea, yet molecular basis underlying cold tolerance tea plants (Camellia sinensis) remains largely unknown. Here, we identified a circadian rhythm component LUX ARRHYTHMO (LUX) that potentially regulates through genome-wide association study transcriptomic analysis. The expression CsLUX phased with sunrise sunset was strongly induced by stress. Genetic assays indicated is positive regulator freezing in plants. directly activated CsCBF1 repressed level CsLOX2, which dynamically modulating jasmonic acid content. Furthermore, showed CsLUX-CsJAZ1 complex attenuated physical interaction CsJAZ1 CsICE1, liberating CsICE1 transcriptional activities to withstand Notably, single-nucleotide variation C-to-A coding region functionally validated as potential elite haplotype for response, provided valuable markers future resistance breeding

Abstract Background The tea plant ( Camellia sinensis (L.) O. Kuntze) is one of the most economically important woody crops. Plastic greenhouse covering cultivation has been widely used in areas northern China. Chlorophyll not only crucial pigment for green tea, but also plays an role growth and development plants. Currently, little known about effect plastic on chlorophyll leaves. Results To investigate leaves, color difference values, contents, gene expression, enzyme activities photosynthetic parameters were analyzed our study. Sensory evaluation showed appearance, liquor infused leaves was greener than field tea. Color analysis revealed that value ∆L, ∆b b/a significantly higher Significant increase content, intracellular CO 2 , stomatal conductance, transpiration rate, net rate observed expression chlorophyll-metabolism-related enzymes activated by covering. Conclusion contents a, b total samples primarily due to especially, a synthetase (chlG), pheophorbide oxygenase (PAO) chlorophyllide (CAO) covered greenhouse. In general, results molecular basis metabolism caused cultivation, which had great significance production

Low-temperature stress limits global tea planting areas and production efficiency. Light is another essential ecological factor that acts in conjunction with temperature the plant life cycle. However, it unclear whether differential light environment affects low adaptability of (Camellia sect. Thea). In this study, materials three groups intensity treatments showed differentiated characteristics for low-temperature adaptability. Strong (ST, 240 μmol·m-2·s-1) caused degradation chlorophyll a decrease peroxidase (POD), superoxide dismutase (SOD), catalase (CAT), ascorbate (APX), polyphenol oxidase (PPO) activities, as well an increase soluble sugar, protein, malondialdehyde (MDA), relative conductivity leaves. contrast, antioxidant enzyme content, were highest weak (WT, 15 μmol·m-2·s-1). Damage was observed both ST WT to moderate (MT, 160 frost resistance test. Chlorophyll strong behavior prevented photodamage, maximum photosynthetic quantum yield PS II (Fv/Fm) decreased increasing intensity.
