“…Accumulation and deposition of soluble carbohydrates has been proposed to contribute to cold 269 tolerance (Trischuk et al, 2014). In support of this observation, our results showed that genes 270 involved in carbohydrate storage and RNA-protein complex biogenesis in NO and SN promoted 271 cold tolerance.…”

“…The coping responses of alfalfa to freezing conditions in winter can be divided into three distinct phases: acclimation, freezing, and de-acclimation [1,2]. The initial step of acclimation is growth reduction triggered by the shorter photoperiod and lower temperatures in the fall [3].…”

Background: Alfalfa is a high-quality forage cultivated widely in northern China. Recently, the failure of alfalfa plants to survive the winter has caused substantial economic losses. Water management has attracted considerable attention as a method for the potential improvement of winter survival. The aim of this study was to determine whether and how changes in the water regime affect the freezing tolerance of alfalfa. Results: The alfalfa variety WL353LH was cultivated under water regimes of 80 and 25% of water-holding capacity, and all the plants were subjected to low temperatures at 4/0°C (light/dark) and then − 2/− 6°C (light/dark). The semi-lethal temperatures were lower for water-stressed than well-watered alfalfa. The pool sizes of total soluble sugars, total amino acids, and proline changed substantially under water-deficit and low-temperature conditions. Metabolomics analyses revealed 72 subclasses of differential metabolites, among which lipid and lipid-like molecules (e.g., fatty acids, unsaturated fatty acids, and glycerophospholipids) and amino acids, peptides, and analogues (e.g., proline betaine) were upregulated under water-deficit conditions. Some carbohydrates (e.g., Dmaltose and raffinose) and flavonoids were also upregulated at low temperatures. Finally, Kyoto Encyclopedia of Genes and Genomes analyses revealed 18 significantly enriched pathways involved in the biosynthesis and metabolism of carbohydrates, unsaturated fatty acids, amino acids, and glycerophospholipids. Conclusions: Water deficit significantly enhanced the alfalfa' freezing tolerance, and this was correlated with increased soluble sugar, amino acid, and lipid and lipid-like molecule contents. These substances are involved in osmotic regulation, cryoprotection, and the synthesis, fluidity, and stability of the cellular membrane. Our study provides a reference for improving alfalfa' winter survival through water management.

“…An analysis of morphological traits under low temperature conditions indicated that seedling height, and shoot dry weights decreased as temperature decreased in sorghum (Yu et al, 2004). Higher concentrations of soluble sugars, glucose and proline were positively associated with low temperature stress, which acted as osmotic substances to preserve protein structure and function (Patton et al, 2007;Burbulis et al, 2011;Trischuk et al, 2014;Farooq et al, 2016). Low temperature stress induced the accumulation of reactive oxygen species (ROS) such as superoxide, hydrogen peroxide, and hydroxyl radicals (Suzuki and Mittler, 2006;Farooq et al, 2009).…”

Identifying differentially expressed genes associated with tolerance against low temperature stress in Brassica napus through transcriptome analysis. AbstractUnder direct-seeding method of sowing, seedling survival is adversely affected due to low temperature. The purpose of this study was to understand the morphological, physiological and molecular response of rapeseed resistance to low temperature stress at seedling establishment. Two varieties Qinyou No.7 (resistant biotype) and Fengyou 730 (sensitive biotype) were used for morphological and physiological experiments under low temperature stress and the resistant variety was used for transcriptome analysis based on the Illumina HiSeq 2000 platform. Results showed resistant variety initiated osmotic regulation system firstly and then triggered the antioxidant enzyme system when exposed to low temperature stress for long duration. The MDA content firstly tended to increase and then decreased in resistant variety, but it continued to increase in sensitive variety. Through transcriptome analysis of Qinyou No. 7 under low temperature for 0 h, 24 h, 48 h and 96 h, 2254 differentially expressed unigenes clustering in 7 expression patterns were participated in low temperature stress. Proteinserine/threonine kinases, myo-inositol-1-phosphate synthases and calmodulins, as the members of ABA and IP3/Ca2+ signal transduction pathway, played an important role in the low temperature stress. Different expressed genes dataset provides useful candidate genes for functional analysis of rapeseed resistance to low temperature.
