“…Perturbance of photosynthetic machinery in Strawberry, also reflected by chlorophyll fluorescence ((Fv/Fm) and LTS significantly reduced the chlorophyll fluorescence (Fv/Fm) value (Zareei et al, 2021). Pradhan et al (2019) also found reduction in Fv/Fm during LTS. The treated plants expressed a significantly lower Fv/Fm value than the control.…”

“…Coral had a lower total soluble sugar content. Pradhan et al (2019) found that cold (20°/10°C; day/night) exposed papaya plants had 117.10 percent higher total soluble sugars than control plants. Polyamines, such as putrescine (Put), spermidine spermidine: (Spd), and spermine (Spm), play a significant role in the green mango (Mangifera indica L. 'Kensington Pride') LT tolerance during storage (Nair and Singh, 2004).…”

“…Under completely controlled conditions. Pradhan et al (2019) evaluate the effects of five LT regimes on five Carica papaya genotypes and one distantly related cold-tolerant plant, V. cundinamarcensis, They observed lower MDA content in the cold-tolerant papaya genotype and V. cundinamarcensis than in the other C. papaya genotypes. The higher rate of oxidation of membrane lipids in susceptible genotypes was linked to a higher amount of MDA, which caused damage to the membrane.…”

Physio-biochemical and molecular stress regulators and their crosstalk for low-temperature stress responses in fruit crops: A review

Low-temperature stress (LTS) drastically affects vegetative and reproductive growth in fruit crops leading to a gross reduction in the yield and loss in product quality. Among the fruit crops, temperate fruits, during the period of evolution, have developed the mechanism of tolerance, i.e., adaptive capability to chilling and freezing when exposed to LTS. However, tropical and sub-tropical fruit crops are most vulnerable to LTS. As a result, fruit crops respond to LTS by inducing the expression of LTS related genes, which is for climatic acclimatization. The activation of the stress-responsive gene leads to changes in physiological and biochemical mechanisms such as photosynthesis, chlorophyll biosynthesis, respiration, membrane composition changes, alteration in protein synthesis, increased antioxidant activity, altered levels of metabolites, and signaling pathways that enhance their tolerance/resistance and alleviate the damage caused due to LTS and chilling injury. The gene induction mechanism has been investigated extensively in the model crop Arabidopsis and several winter kinds of cereal. The ICE1 (inducer of C-repeat binding factor expression 1) and the CBF (C-repeat binding factor) transcriptional cascade are involved in transcriptional control. The functions of various CBFs and aquaporin genes were well studied in crop plants and their role in multiple stresses including cold stresses is deciphered. In addition, tissue nutrients and plant growth regulators like ABA, ethylene, jasmonic acid etc., also play a significant role in alleviating the LTS and chilling injury in fruit crops. However, these physiological, biochemical and molecular understanding of LTS tolerance/resistance are restricted to few of the temperate and tropical fruit crops. Therefore, a better understanding of cold tolerance’s underlying physio-biochemical and molecular components in fruit crops is required under open and simulated LTS. The understanding of LTS tolerance/resistance mechanism will lay the foundation for tailoring the novel fruit genotypes for successful crop production under erratic weather conditions.

“…Temperature is often considered more important than precipitation in climate change context (Pepin et al 2015, Bjorkman et al 2018, Vitasse et al 2018), however, our results suggested that change in precipitation (cultivation – original climate) had stronger effect on plant traits than change in temperature. Additionally, structural traits are the most used to understand climate change impacts (Valverde-Barrantes et al 2017, Bjorkman et al 2018, Henn et al 2018, Yang et al 2019, Shen et al 2019) [biochemical in case of a few crop or experimental species (Renaut et al 2005, Lei et al 2006, Hekneby et al 2006, Pradhan et al 2019)], and the effects were stronger in biochemical traits. Especially, photosynthesis related traits were the most affected by climate change (cultivation – original climate) suggesting that the most important process leading to primary production in the Biosphere is the most sensitive to climate change.…”

Exploring patterns and causes of intraspecific trait variation is crucial for a better understanding of the effects of climate change on plant populations and ecosystems. However, our current understanding of the intraspecific trait variation is mainly based on structural (morphological) traits, and we have limited knowledge on patterns and causes of variation in biochemical traits (e.g., leaf pigments) which are also crucial for plant adaptation. As a result, we also do not know how similar the climatic effects on structural versus biochemical traits are.Using plant traits from 110 genotypes representing 11 populations of Festuca rubra grown in 4 different climates, we studied trait covariation among structural traits (linked to fitness, resource use, gas exchange and reproduction) and biochemical traits (linked to photosynthesis, photoprotection and oxidative stress). We also disentangled the relative role of climate of origin and cultivation climate on structural versus biochemical traits and tested for adaptive plasticity in the traits.We found that 1) biochemical traits did not covary with structural traits and represent ‘photoharvesting – photoprotection’ strategy dimension of functional variation; 2) the interactive effects of climate of origin and cultivation were more pronounced for biochemical than structural traits. 3) Trait plasticity was affected by the climate of origin (precipitation and temperature as well as their interaction); 4) F. rubra showed both adaptive as well as mal-adaptive plasticity and adaptiveness depends upon trait type, cultivation climate and climate of origin.Overall, our results suggest that structural and biochemical plant traits respond differentially to climate and response of one group of traits thus cannot be predicted from the other. The responses are also strongly determined by interactions between the climate of origin and cultivation. More studies on variation in biochemical traits, their correspondence to other traits and their variation with climate are thus needed.

“…The results of this experiment also demonstrated that tolerant cultivars are more capable to decrease rapidly the RWC. The low relative RWC in tolerant cultivars under low temperatures can also be due to the breakdown of large molecules such as polysaccharides and the production of simpler sugars which increases the osmotic potential and decreases the relative water contents [ 26 , 27 ].…”

Background In northern Iran and other cold regions, winter freezing injury and resultant yield instability are major limitations to strawberry production. However, there is scarcity of information on the physiological and biochemical responses of strawberry cultivars to freezing stress. This study aimed to investigate the physiological and biochemical responses of strawberry cultivars (Tennessee Beauty, Blakemore, Kurdistan, Queen Elisa, Chandler, Krasnyy Bereg, and Yalova) to different freezing temperature treatments (− 5, − 10, − 15, − 20, and − 25 °C) under controlled conditions. Results All measured physiological and biochemical features were significantly affected by the interaction effect between low temperatures and cultivars. Tennessee Beauty showed the highest RWC at − 25 °C. The highest Fv/Fm was observed in Queen Elisa. Krasnyy Bereg had the least freezing injury (FI) in crown and leaf, while Yalova and Chandler showed the highest crown and leaf FI, respectively. At − 20 to − 25 °C, the highest carbohydrates contents of crown and leaf were noted in Blakemore and Krasnyy Bereg cultivars, respectively. The Yalova showed the highest protein content in both crown and leaf tissues at − 25 °C. The Tennessee Beauty and Blackmore cultivars showed the highest proline in crowns and leaves at − 15 °C, respectively. The highest ThioBarbituric Acid Reactive Substances (TBARS) contents in the crown and leaf were observed in Kurdistan and Queen Elisa, respectively. Queen Elisa and Krasnyy Bereg cultivars showed SOD and POD peaks in the crown at − 15 °C, respectively. Conclusion Freezing stress was characterized by decreased Fv/Fm and RWC, and increased FI, TBARS, total carbohydrates, total proteins, proline content, and antioxidant enzyme activity. The extent of changes in above mentioned traits was cultivar dependent. FI and TBARS were the best traits among destructive parameters for evaluating freezing tolerance. Moreover, maximum quantum yield of PSII (Fv/Fm index), as non-destructive parameters, showed a significant efficiency in rapid assessment for screening of freezing tolerant strawberry cultivars. The cultivars Krasnyy Bereg, Queen Elisa, and Kurdistan were the most tolerant cultivars to freezing stress. These cultivars can be used as parents in breeding programs to develop new freezing tolerant cultivars.
