Jute (Corchorus spp.) belongs to the Malvaceae family, and there are two species of jute, C. capsularis and C. olitorious. It is the second-largest natural bast fiber in the world according to production, which has diverse uses not only as a fiber but also as multiple industrial materials. Because of climate change, plants experience various stressors such as salt, drought, heat, cold, metal/metalloid toxicity, and flooding. Although jute is particularly adapted to grow in hot and humid climates, it is grown under a wide variety of climatic conditions and is relatively tolerant to some environmental adversities. However, abiotic stress often restricts its growth, yield, and quality significantly. Abiotic stress negatively affects the metabolic activities, growth, physiology, and fiber yield of jute. One of the major consequences of abiotic stress on the jute plant is the generation of reactive oxygen species, which lead to oxidative stress that damages its cellular organelles and biomolecules. However, jute’s responses to abiotic stress mainly depend on the plant’s age and type and duration of stress. Therefore, understanding the abiotic stress responses and the tolerance mechanism would help plant biologists and agronomists in developing climate-smart jute varieties and suitable cultivation packages for adverse environmental conditions. In this review, we summarized the best possible recent literature on the plant abiotic stress factors and their influence on jute plants. We described the possible approaches for stress tolerance mechanisms based on the available literature.

Genus Sedum (family Crassulaceae) - succulents adapted to lack of moisture. Morphophysiological reactions of immature Sedum hybridum L. (Aizopsis hybrida (L.) Grulich) plants to stressful conditions of water scarcity, salinization and low positive temperatures are described. The high resistance of plants to the studied stress effects is shown. The tendency of the dynamics of the highest moisture loss by plants of the control group and the lowest by plants cultivated at PEG–6000 at a concentration of 200 mmol/l was noted, which indicates the adaptive effect of this level of osmotic stress on Sedum hybridum plants. To obtain a completely dry Sedum hybridum mass for various physiological experiments, it is necessary to maintain the plant material at a temperature of 105⸰ C, with at least 40 hours.

Climatic changes have great impact on the crops and agro-eco systems and such changes influences the concentration of secondary metabolites. IIT Kharagpur, India is a non-traditional tea growing zone where Tocklai Vegetative 25 variety was used as the research material. This study reports the development of a chemometrics assisted HPLC method validated as per ICH guidelines to explore the effect of seasonal variations in polyphenolics viz. catechins and methyl xanthenes like caffeine in fresh tea leaves and processed CTC black tea prepared from them. Further study was done on the variances amongst the concentration of secondary metabolites and abiotic stress factors. Good resolutions of secondary metabolites were obtained using 92% of 0.2% acetic acid and 8% of acetonitrile as the mobile phase, with a flow rate of 1 mL/ min, injection volume of 20 µl,  PDA detector was set at 200-600 nm and chromatograms were recorded at 274 nm. Results of quantitative HPLC analysis have clearly shown that highest yield of catechins and caffeine were observed in fresh tea leaves plucked during spring (24.3ºC temperature and average rainfall of 34 mm) and also the processed black tea made from it, followed by tea leaves plucked during monsoon (28.8 ºC temperature and 282 mm rainfall) and processed black tea prepared from it. The lowest concentrations of secondary metabolites were found in leaves plucked during autumn (26.2 °C temperature and 132 mm rainfall) and the processed tea prepared from it. The developed quantitative HPLC method showed an inter day precision of 0.3, intraday precision of 0.2, repeatability value of 0.31, ruggedness value of 0.33 and robustness value of 0.2. Considering temperature and rainfall as abiotic stress factors, highest total polyphenolic content was obtained during spring and lowest in autumn. From our experimental findings, the fresh tea leaves of spring season and also the processed black tea prepared from it showed higher yield of catechins.
