“…Field-grown wheat exposed to 25 • C was acclimated to reduce dark respiration, leading to lesser yield loss [32]. In pea seedlings, drought stress led to a significant reduction in mitochondrial respiration, and its recovery was hastened by chilling stress of 15 • C [75]. Thus, global warming can bring down the net carbon gain by rising plant respiration rates [37].…”

Plants are a highly advanced kingdom of living organisms on the earth. They survive under all climatic and weather variabilities, including low and high temperature, rainfall, radiation, less nutrients, and high salinity. Even though they are adapted to various environmental factors, which are variable, the performance of a crop will be compensated under sub/supra optimal conditions. Hence, current and future climate change factors pose a challenge to sustainable agriculture. Photosynthesis is the primary biochemical trait of crops that are affected by abiotic stress and elevated CO2 (eCO2). Under eCO2, the C3 legumes could perform better photosynthesis over C4 grasses. The associated elevated temperature promotes the survival of the C4 crop (maize) over C3 plants. In the American Ginseng, the elevated temperature promotes the accumulation of phytocompounds. Under less water availability, poor transpirational cooling, higher canopy temperatures, and oxidative stress will attenuate the stability of the membrane. Altering the membrane composition to safeguard fluidity is a major tolerance mechanism. For protection and survival under individual or multiple stresses, plants try to undergo high photorespiration and dark respiration, for instance, in wheat and peas. The redox status of plants should be maintained for ROS homeostasis and, thereby, plant survival. The production of antioxidants and secondary metabolites may keep a check on the content of oxidating molecules. Several adaptations, such as deeper rooting, epicuticular wax formation such as peas, and utilization of non-structural carbohydrates, i.e., wheat, help in survival. In addition to yield, quality is a major attribute abridged or augmented by climate change. The nutrient content of cereals, pulses, and vegetables is reduced by eCO2; in aniseed and Valeriana sp., the essential oil content is increased. Thus, climate change has perplexing effects in a species-dependent manner, posing hurdles in sustainable crop production. The review covers various scientific issues interlinked with challenges of food/nutritional security and the resilience of plants to climate variability. This article also glimpses through the research gaps present in the studies about the physiological effects of climate change on various crops.

Effects of Auxin-Type Plant Growth Regulators and Cold Stress on the Endogenous Polyamines in Pea Plants

The effect of pre-application of structural auxin analogues TA-12 (1-[2-chloroethoxycarbonyl-methyl]-4-naphthalenesulfonic acid calcium salt) and TA-14 (1-[2-dimethylaminoethoxicarbonylmethyl] naphthalenechlormethylate) on biochemical parameters of pea (Pisum sativum L. cv. Jablo) plants subjected to low temperature (LT, −1 °C, for 24h) was studied. For the first time the effects of these auxin analogues, applied with or without LT were investigated on the endogenous polyamine (PA) content. The LT treatment increased free and bound putrescine (Put) and spermine (Spm), conjugated and bound spermidine (Spd), accompanied by a decrease in conjugated Put and Spm, and free Spd. Stress biomarkers hydrogen peroxide (H2O2) and malondialdehyde (MDA) as well as proline were augmented by LT treatment. The TAs application decreased conjugated polyamines (Put, Spm and Spd), free Spd, H2O2 and MDA but increased bound Spm and proline in pea plants. The application of TAs before LT lessened the alterations in PAs (mainly in free and bound fractions) and stress biomarkers content caused by LT, and enhanced conjugated Spd and phenolics, which contributed to increased plant cold tolerance.
