“…However, numerous plants like Hippophae rhamnoides , Lepidium latifolium , etc. have a tendency to acclimatize in low temperatures; hence, they are successfully colonized in colder regions of the world, owing to the remarkable activities of their cold responsive-genes [5,6]. Proteins from these genes viz.…”

Low-temperature stress severely affects the growth, development, and geographical distribution of various crop plants, resulting in significant economic loss to producers. In a quest to identify cold-regulated genes, we constructed a cDNA suppression subtractive library from a high altitude adapted ecotype of Lepidium. We cloned a cold-induced gene LlaCIPK from the subtracted cDNA library which gave homology to Arabidopsis CIPK15 gene. The predicted 3D structure of LlaCIPK protein also showed homology with Arabidopsis CIPK protein. Quantitative real-time PCR analysis in Lepidium seedlings exposed to 6 h of cold stress shows a 3-fold increase in the expression of LlaCIPK transcript. The expression of LlaCIPK was also differentially regulated by ethylene, CaCl2, ABA, and SA treatments. Ethylene and CaCl2 treatments up regulated LlaCIPK expression, whereas ABA and SA treatments down regulated the LlaCIPK expression. Transgenic plants overexpressing LlaCIPK gene under constitutive promoter show an increased level of proline and cell membrane stability. Taken together, our results suggest that the LlaCIPK contributes to the cold-response pathway in Lepidium plants.

“…Also GO and KEGG enrichment analysis showed that the DEGs were enriched in genes involved in antioxidant-related glutathione metabolism processes. Under cold stress, plant cells accumulate proline to protect against protein denaturation [ 52 ]; in cotton seedlings treated with EBR, the proline content was higher than in the control and the plants had greater cold tolerance. The cotton seedlings treated with EBR under cold stress had higher Pn.…”

In plants, brassinosteroids (BRs) are a class of steroidal hormones that are involved in numerous physiological responses. However, the function of BRs in cold tolerance in cotton has not been explored. In this study, cotton seedlings were treated with five concentrations (0, 0.05, 0.1, 0.2, 0.5 and 1.0 mg/L) of 24-Epibrassinolide (EBR) at 4°C. We measured the electrolyte leakage, malondialdehyde (MDA) content, proline content, and net photosynthesis rate (Pn) of the seedlings, which showed that EBR treatment increased cold tolerance in cotton in a dose-dependent manner, and that 0.2 mg/L is an optimum concentration for enhancing cold tolerance. The function of EBR in cotton cotyledons was investigated in the control 0 mg/L (Cold+water) and 0.2 mg/L (Cold+EBR) treatments using RNA-Seq. A total of 4,001 differentially expressed genes (DEGs), including 2,591 up-regulated genes and 1,409 down-regulated genes were identified. Gene Ontology (GO) and biochemical pathway enrichment analyses showed that EBR is involved in the genetic information process, secondary metabolism, and also inhibits abscisic acid (ABA) and ethylene (ETH) signal transduction. In this study, physiological experiments showed that EBR can increase cold tolerance in cotton seedlings, and the comprehensive RNA-seq data shed light on the mechanisms through which EBR increases cold tolerance in cotton seedlings.

Hippophae salicifolia is an Euro-Asian species used in many industries, from medicine to cosmetics, nutrition, or soil sciences (enriching degraded fields, diminishing soil erosion, preventing and treating diseases). The purpose of this study was to analyse the culture of this species in Europe together with the chemical content of its fruits. In order to achieve this, Hippophae salicifolia seeds were sown in greenhouses, seedlings were planted in fields, while the fruits were harvested and analysed both fresh, as well as after preservation for 1 year and 5 months. The properties of H. salicifolia fruits were also compared with the fruits of Hippophae rhamnoides, both fresh and preserved for 7 months. The analysis have shown that fresh fruits contain an average quantity of 31; 811 and 231 mg/100 total carotenoid, polyphenol, and ascorbic acid, respectively. The vitamin C content was much higher than that observed for H. rhamonides. If kept in adequate conditions, H. salicifolia fruits lose only a small amount of vitamin C and exhibit a vitamin C content (224 mg/100g) superior to the fresh fruit of H. rhamonides (100-150 mg/100 g). By comparing the chemical characteristics of H. salicifolia and H. rhamnoides fruits preserved over a long period of time, a higher concentration of vitamin C was observed in H. salicifolia, while the differences between the other chemical characteristics were insignificant. The obtained results strongly suggest that H. salicifolia can be successfully cultured in Europe, while its exceptional fruit qualities can be capitalised on by a variety of industries.
