“…This result shows that ABA may also be associated with the defense system in plants. Furthermore, ethylene productions in 14-day-old Arabidopsis thaliana were increased by UV-B irradiation of 30 or 60 min (Rakitin et al 2008). It has been demonstrated that JA-ethylene cross talk restrains local cell expansion in Nicotiana attenunta leaves, because ectopic cell expansion was observed around Manduca sexta oral secretions-treated wounds in only JA-deficient and ethylene-insensitive samples (Onkokesung et al 2010).…”

Jasmonic acid, polyamine, and antioxidant levels in apple seedlings as affected by Ultraviolet-C irradiation

The effect of UV-C irradiation on jasmonates, abscisic acid (ABA), polyamines and antioxidant activities was investigated in apple plants (Malus domestica Borkh.). The EC 50 values of O 2 --scavenging activity in the UV-C treated leaves were lower than those in the untreated control. In addition, total ascorbic acid and polyphenolic concentrations in the UV-C treated leaves were generally higher than those in the untreated control. Although the endogenous ABA concentrations were not significantly different between the untreated control and UV-C treatment, the endogenous jasmonic acid, putrescine, and spermine concentrations in the UV-C treated plants were higher than those in the untreated control. However, the application of PDJ before UV treatment inhibited the rise of endogenous jasmonate and putrescine concentrations. The increase of ascorbic acid was also inhibited by PDJ application before UV treatment. These facts suggest that the increase of jasmonates and polyamines may be associated with UV-C stimulation, and UV-C irradiation may be effective for increasing antioxidant activity in apple leaves.

“…It has been shown that UV irradiation induced growth retardation in Arabidopsis thaliana (Rakitin et al 2008) and soybean (Glycine max L.) plants (Shen et al 2010). This may be caused by damage to the tissue by UV irradiation (Rakitin et al 2009).…”

“…The adverse changes of ABA in Experiment I versus Experiment II indicate that multiple mechanisms coexist in plants, and the one to choose depends on different circumstances. Previous studies observed an increase of ABA content after UVB treatment in maize and Arabidopsis (Rakitin et al ., 2008; Tossi et al ., 2009, 2012). In Experiment III , the plants under the combinations of low temperature and UVB stresses showed a decrease of ABA on 7‐day treatment and an increase from 7‐ to 56‐day treatment (Figure 3c), which might be due to the combination of multiple stresses, but the rationale behind it needs further investigation.…”

Factors affecting freezing tolerance: a comparative transcriptomics study between field and artificial cold acclimations in overwintering evergreens

et al. 2020

Summary Cold acclimation (CA) is a well‐known strategy employed by plants to enhance freezing tolerance (FT) in winter. Global warming could disturb CA and increase the potential for winter freeze‐injury. Thus, developing robust FT through complete CA is essential. To explore the molecular mechanisms of CA in woody perennials, we compared field and artificial CAs. Transcriptomic data showed that photosynthesis/photoprotection and fatty acid metabolism pathways were specifically enriched in field CA; carbohydrate metabolism, secondary metabolism and circadian rhythm pathways were commonly enriched in both field and artificial CAs. When compared with plants in vegetative growth in the chamber, we found that the light signals with warm air temperatures in the fall might induce the accumulation of leaf abscisic acid (ABA) and jasmonic acid (JA) concentrations, and activate Ca2+, ABA and JA signaling transductions in plants. With the gradual cooling occurrence in winter, more accumulation of anthocyanin, chlorophyll degradation, closure/degradation of photosystem II reaction centers, and substantial accumulation of glucose and fructose contributed to obtaining robust FT during field CA. Moreover, we observed that in Rhododendron ‘Elsie Lee’, ABA and JA decreased in winter, which may be due to the strong requirement of zeaxanthin for rapid thermal dissipation and unsaturated fatty acids for membrane fluidity. Taken together, our results indicate that artificial CA has limitations to understand the field CA and field light signals (like short photoperiod, light intensity and/or light quality) before the low temperature in fall might be essential for complete CA.

“…Numerous studies have shown that UV-B (280–320 nm) is a biologically effective radiation, and most plants are subject to the stress and generate stress responses upon exposure [ 6 ]. For example, numerous studies have shown that enhanced UV-B radiation leads to dwarfing of plants and shortening of internodes [ 7 , 8 ]. However, plants can compensate for the reduced leaf area caused by UV-B radiation by increasing the number and thickness of leaves [ 9 ].…”

Mirabilis himalaica (Edgew.) Heimerl is one of the most important genuine medicinal plants in Tibet, in which the special plateau habitat has been associated with its excellent medicinal quality and efficacy. However, the mechanisms by which environmental factors affect biosynthesis of secondary metabolic components remain unclear in this species. In this study, RNA sequencing and iTRAQ (isobaric Tags for Relative and Absolute Quantification) techniques were used to investigate the critical molecular “events” of rotenoid biosynthesis responding to UV-B radiation, a typical plateau ecological factor presented in native environment-grown M. himalaica plants. A total of 3641 differentially expressed genes (DEGs) and 106 differentially expressed proteins (DEPs) were identified in M. himalaica between UV-B treatment and control check (CK). Comprehensive analysis of protein and transcript data sets resulted in 14 and 7 DEGs from the plant hormone signal transduction and phosphatidylinositol signaling system pathways, respectively, being significantly enriched. The result showed that the plant hormone signal transduction and phosphatidylinositol signaling system might be the key metabolic strategy of UV-B radiation to improve the biosynthesis of rotenoid in M. himalaica. At same time, most of the DEGs were associated with auxin and calcium signaling, inferring that they might drive the downstream transmission of these signal transduction pathways. Regarding those pathways, two chalcone synthase enzymes, which play key roles in the biosynthesis of rotenoid that were thought as the representative medicinal component of M. himalaica, were significantly upregulated in UV-B radiation. This study provides a theoretical basis for further exploration of the adaptation mechanism of M. himalaica to UV-B radiation, and references for cultivation standardization.
