“…In this study, the concentration of proline and soluble sugar were increased in shoots under low temperature, and the increase in resistant variety was significantly higher than sensitive variety. Similar results were also found in previous researches (Kushad and Yelenosky, 1987;Patton et al, 2007;Burbulis et al, 2011;Li et al, 2013). Carbohydrate and protein metabolism is the foundation for the rapeseed seedling establishment (Patton et al, 2007;Lutz, 2010).…”

“…Peroxidases are a kind of antioxidant enzymes, which can remove ROS in plant cell (Breusegem et al, 1999). Previous studies mainly focused on SOD, POD and CAT activities, however, due to the material properties and the difference of stress duration and intensity, changes in antioxidant enzymes under low temperature stress were not so regular (Gechev et al, 2003;Zhang et al, 2011;Li et al, 2013). In our experiment, the resistant variety initiated osmotic regulation system firstly and then triggered the antioxidant enzyme system when exposed to low temperature stress for long duration.…”

“…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). These ROS may be signals inducing ROS scavengers and other protective mechanisms, as well as damaging agents contributing to stress injury in plants (Xiong et al, 2002;Airaki et al, 2012;Li et al, 2013;;Farooq et al, 2016)). Diverse plant species tolerate cold stress to a varying degree, which depends on reprogramming gene expression to modify their physiology, metabolism, and growth (Chinnusamy et al, 2010).…”

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.

“…During the course of NaHS treatment and heat stress, antioxidant enzymes CAT, GPX, SOD, GR and APX in maize seedlings were extracted and measured according to our methods described previously (Li et al 2013c). In brief, maize seedlings (0.5 g) were ground in a mortar with a pestle in 5 mL of extraction buffer contained 50 mM Tris-HCl (pH 7.0), 0.1 mM EDTA, 1 mM AsA, 1 mM dithiothreitol (DTT) and 5 mM MgCl2.…”

Hydrogen sulfide (H2S) is a signal molecule that is involved in plant growth, development and the acquisition of stress tolerance including heat tolerance, but the mechanism of H2S-induced heat tolerance is not completely clear. In present study, the effect of sodium hydrosulfide (NaHS), a H2S donor, treatment on heat tolerance of maize seedlings in relation to antioxidant system was investigated. The results showed that NaHS treatment improved survival percentage of maize seedlings under heat stress in a concentration-dependent manner, indicating that H2S treatment could improve heat tolerance of maize seedlings. To further study mechanism of NaHS-induced heat tolerance, catalase (CAT), guaiacol peroxidase (GPX), superoxide dismutase (SOD), glutathione reductase (GR) and ascorbate peroxidase (APX) activities, and glutathione (GSH) and ascorbic acid (AsA) contents in maize seedlings were determined. The results showed that NaHS treatment increased the activities of CAT, GPX, SOD and GR, and GSH and AsA contents as well as the ratio of reduced antioxidants to total antioxidants [AsA/(AsA+DHA) and GSH/(GSH +GSSG)] in maize seedlings under normal culture conditions compared with the control. Under heat stress, antioxidant enzymes activities, antioxidants contents and the ratio of the reduced antioxidants to total antioxidants in control and treated seedlings all decreased, but NaHS-treated seedlings maintained higher antioxidant enzymes activities and antioxidants levels as well as the ratio of reduced antioxidants to total antioxidants. All of above-mentioned results suggested that NaHS treatment could improve heat tolerance of maize seedlings, and the acquisition of this heat tolerance may be relation to enhanced antioxidant system activity.

Stress-Tolerant Feedstocks for Sustainable Bioenergy Production on Marginal Land

Given the mandated increases in fuel production from alternative sources, limited high-quality production land, and predicted climate changes, identification of stress-tolerant biomass crops will be increasingly important. However, existing literature largely focuses on the responses of a small number of crops to a single source of abiotic stress. Here, we provide a much-needed review of several types of stress likely to be encountered by biomass crops on marginal lands and under future climate scenarios: drought, flooding, salinity, cold, and heat. The stress responses of 17 leading biomass crops of all growth habits (e.g., perennial grasses, shortrotation woody crops, and large trees) are summarized, and we identify several that could be considered "all purpose" for multiple stress types. Importantly, we note that some of these crops are or could become invasive in some landscapes. Therefore, growers must take care to avoid dissemination of plants or propagules outside of cultivation.
