“…The CBF gene in potato is rapidly activated at low temperatures. In turn, this induces the expression of a set of downstream cold-responsive genes, COR47 and COR413 , thereby enhancing the freezing tolerance of potato plants [ 34 ]. RD29a , a key gene in the Arabidopsis ABA signaling pathway, contains two cis-acting elements, one of which is DRE (dehydration response element), which responds to drought, high salinity, and low-temperature stress [ 35 ].…”

Cold stress is a prominent abiotic factor that adversely affects the growth and yield of pears, consequently restricting the cultivation range and resulting in substantial economic losses for the pear industry. Basic region–leucine zipper (bZIP) transcription factors are widely involved in multiple physiological and biochemical activities of plants, particularly in response to cold stress. In this study, the responsiveness of PbbZIP11 in pear to cold stress was investigated, and its role was explored by using pear callus and Arabidopsis thaliana. The findings revealed that overexpression of PbbZIP11 enhanced the tolerance of pear callus and Arabidopsis thaliana to cold stress. The antioxidant enzyme activities of transgenic plants were enhanced and the expression of C-repeat binding transcription factor (CBF) genes was increased as compared to wild-type plants. To better understand the biological function of PbbZIP11, mRNAs were isolated from overexpressed and wild-type Arabidopsis thaliana after cold stress for whole-genome sequencing. The results showed that the expression of some CBF downstream target genes changed after exposure to cold stress. The results suggested that the PbbZIP11 gene could participate in cold-stress signaling through the CBF-dependent pathway, which provides a theoretical basis for the PbbZIP11-mediated response to cold stress and for the genetic breeding of pear varieties with low-temperature tolerance.

“…The study on plant chilling injury has a key significance for the regulation network of ICE-CBF-COR in plant cold resistance (Wang et al, 2017a). Many COR413 gene family members are differentially expressed after abiotic stress (Ruibal et al, 2020). Results from P. davidiana x P. bolleana (Guo et al, 2009) and Arabidopsis thaliana (Su et al, 2018) suggest that COR413 plays an important role in improving plant cold tolerance.…”

Peach were susceptible to chilling injury during low temperature (0 o C) storage at postharvest, and LTC (Low temperature conditioning) treatment could reduce chilling injury such as of H2O2 production and fruit browning. In order to study the function of peach COR413 in the regulation of postharvest chilling injury in peach 'Beijing No. 9', four COR413 gene family members were identified based on the peach genome database, namely PpCOR1~PpCOR4. Phylogenetic analysis showed that the four PpCORs could be clustered into two subfamilies. PpCOR1~PpCOR3 belonged to the first subfamily, and most of the members in this subfamily were located in plasma membrane. PpCOR4 belongs to the second subfamily, and its members are mainly located in thylakoid membrane. The cis-acting elements analysis of PpCORs promoter showed that PpCOR3 contained abundant abiotic stress responsive and hormone responsive elements such as jasmonate and abscisic acid. The results of gene expression showed that PpCOR3 was induced by low temperature while LTC treatment could repress the induction of PpCOR3 by low temperature. Interestingly, the expression of PpCOR3 was positively correlated with the change of H2O2 content in peach, which indicated that PpCOR3 was involved in the regulation of postharvest chilling injury in peach fruit. This result provides a theoretical basis for the study of postharvest storage and quality maintenance of peach fruit as well as the breeding of cold resistant peach varieties.

“…They are grouped into two groups, COR413TM/IM (by the thylakoid membrane/inner chloroplast membrane) and COR413PM (by the plasma membrane) [54]. One of the functions that has been suggested in A. thaliana and Physcomytrella patens is that COR413IM1 can alter the distribution of the metabolites involved in physiological processes to accumulate the proteins involved in the metabolism of fatty acids, fructose, starch and sucrose [55,56]. This metabolism adjustment in stressful situations is believed to act as a transporter or to interact physically or functionally with other metabolic transporters by regulating their activity [57].…”

Gene Expression under Short-Term Low Temperatures: Preliminary Screening Method to Obtain Tolerant Citrus Rootstocks

2021

Climate change and global warming are leading to a change in weather patterns toward hot and cold waves. Citrus fruits are a tropical or subtropical crop whose growth is altered by changes in weather patterns. Thus, in the present work, two experiments are evaluated to obtain a screening method to select citrus rootstocks that help us to select new low-temperature-tolerant plant materials. One cold experiment was carried out with the Poncirus trifoliata and Citrus macrophylla rootstocks at 4 °C for 4, 8, 24 and 56 h. A second experiment was performed at 4 °C for 5 days with subsequent acclimatization lasting 0, 5, 10 and 24 h. The expression of the cold response genes CAMTA1, CAMTA3, CAMTA5, CBF1, ICE1 and COR413 IM1 was quantified. The results showed that the best rootstock selection strategy was the second experiment, as a higher expression of the genes CAMTA3, CAMTA5, CBF1 and COR413 IM1 was seen in the tolerant genotype P. trifoliata. We quantified the gene expression of proline biosynthesis P5CS1, dOAT and the proline transporters PROT1 and PROT2; the concentration of the amino acid proline in leaves was also quantified. These results once again showed that the best experiment to differentiate between tolerant and sensitive rootstocks was the second experiment with acclimation time.
