“…focused on disease and pest control (Showalter et al 2018), seed germination (Zhang et al 2015), nutritional development (Wang et al 2018;Zhou et al 2018), reproductive morphological differences (Zhu et al 2016), and ecology and evolution (Li et al 2017). With regards stress tolerance, He et al (2016) reported that changes in the circadian clock or 24-hour rhythm affects the drought tolerance of F. mandshurica with DNA methylation variation involved in the drought response (Zeng et al 2015). However, research around the molecular mechanisms of stress tolerance is lacking.…”

RELATED TO AP2.12 (RAP2.12) is one of the Ethylene Response Factors (ERF) transcription factor and plays a key role in controlling plant root bending and responding to multiple abiotic stresses including hypoxia stress. In this study, FmRAP2.12 gene was isolated and characterized from Fraxinus mandshurica Rupr. The open reading frame (ORF) of FmRAP2.12 was 1170 bp and encoded a protein of 389 amino acids. The conserved domains, three-dimensional phylogenetic relationship of FmRAP2.12 was also investigated. Quantitative real-time (qRT-PCR) analyzed the expression of FmRAP2.12 in different tissues. The expression level of FmRAP2.12 was highest in roots followed by leaves, and lowest in male flowers. Abiotic stress and hormone signal-induced expression was established using qRT-PCR. Salt stress induced FmRAP2.12 to a double peak pattern: the first peak value was at 6 h and the second at 72 h. Drought stress also induced FmRAP2.12 to a double peak pattern: the first at 6 h and the second at 48 h. FmRAP2.12 was up-regulated after initiation of gibberellic acid (GA3) treatment, with a one peak pattern at 24 h. FmRAP2.12 may not respond to cold stress and Abscisic acid (ABA) treatment. The transient overexpression of FmRAP2.12 caused the up-expression of downstream key genes of abiotic stress response and gibberellin pathway. Our research reveals the molecular characteristic and expression patterns under abiotic stress and hormone condition of FmRAP2.12, providing support for the genetic improvement of F. mandshurica at a molecular level.

“…A Pearson's correlation was used to test for a correlation in the pairwise comparisons of variables. The comprehensive evaluation of indicators related to salt tolerance was performed by a subordinate function analysis (Zeng et al, 2015). SPSS v. 22 (IBM, Inc., Armonk, 2016 (Redmond, WA, U.S.A.) was used for calculations.…”

What is already known on this subject?• Salicylic acid plays a key role in the plant response to environmental stress, which can improve the growth and development of a variety of plants under salt stress, and has the potential to become an effective measure to manage plant salt tolerance.• Salicylic acid can indeed improve tolerance of Hosta ensata to salt stress, and this effect may be achieved through regulation of photosynthetic system, osmoregulation system and antioxidant system.What is the expected impact on horticulture?• The results of this study can prove that the application of exogenous salicylic acid is an effective measure to improve the salt tolerance of Hosta ensata, and can provide a reference for the application of salicylic acid in horticultural plant cultivation.

“…Histone modifications play important roles in regulating the expression of C‐4 photosynthetic genes (Li et al ) and hybridization often results in dramatic structural genome reconfigurations, including epigenetic changes, that control gene expression (Koroma et al ). These epigenetic changes after hybridization seem to be related to increased salt tolerance in hybrids (Zeng et al ). More genetic and epigenetic studies are needed to reveal the mechanisms leading to the production of hybrids with enhanced PEPC functionality in relation to different environmental stress factors such as salinity.…”

Hybridization is a relevant evolutionary mechanism linked to the invasiveness of plant species, but little is known about its effect on enzymatic activities in response to stress. We analyzed the effects of salinity on key mechanistic traits of phosphoenolpyruvate carboxylase (PEPC) enzyme for two hybrid taxa derived from native Spartina maritima (Curtis) Fernald and invasive Spartina densiflora Brongn. in comparison with their parental species. Parental species showed contrasted strategies at the PEPC level to cope with salinity. Spartina maritima showed its physiological optimum at 10 to 40 ppt salinity, with high PEPC activity (per unit leaf soluble protein), in contrast to the lower salinity optimum of 0.5 and 10 ppt for S. densiflora, where highest levels of PEPC apparent specific activity coincided with high light-induced activation of PEPC. Both hybrids showed constant PEPC apparent specific activity from fresh water to hypersalinity and exhibited higher net photosynthesis rates in fresh water than their parents. Spartina maritima × densiflora presented three transgressive PEPC-related traits, being the only taxon able to increase its PEPC activation in darkness at high salinity. Spartina densiflora × maritima showed most PEPC-related traits intermediate between its parents. Inheritance types operating differently in reciprocal hybrids determine key functional traits conditioning their ecological performance.
