Abstract In this study, we analyzed the agronomic and physiological indicators of the leaves and roots of 60 hulless barley varieties under low-temperature treatment, identified the crucial indicators that can reflect the ability of hulless barley to tolerate low-temperature, and evaluated the ability of different hulless barley varieties to tolerate low-temperature. The results indicated significant differences in the agronomic and physiological indicators of 60 hulless barley varieties subjected to low-temperature treatment. Most of the agronomic indicators significantly decreased, whereas most of the physiological indicators significantly increased. However, the magnitude of changes in each agronomic and physiological… More >

Abstract Putrescine is reported to be necessary for cold acclimation under low-temperature stress. In this study, the effect of low-temperature on some physiological and biochemical parameters has been investigated using the green algae Chlamydomonas reinhardtii. The lipid peroxidation rate, amount of Rubisco protein, activities of antioxidant enzymes and gene expression of polyamine biosynthesis (odc2, and spd1), heat shock proteins (hsp70c, hsp90a, and hsp90c), and PSII repair mechanisms (psba, rep27, and tba1) were determined to understand the low-temperature response. Exogenous putrescine application significantly increased Rubisco protein concentration and catalase enzyme activities under low-temperature stress. Moreover, real-time RT-PCR results and gene expression analysis… More >

Abstract Since potato cultivars are sensitive to low temperature, cold injury severely affects the geographical distribution and yield of potato. Although some miRNAs have been identified in response to cold stress in plants, there is no report about the role of miRNAs in the response to cold stress in potato. Here, via high throughput sequencing, we described the profiling of cold stress response to miRNA and mRNA in potato. Two small RNA and six mRNA libraries were constructed and sequenced. 296 known and 211 novel miRNAs were identified, in which 34 miRNAs in Cold Group (CG)… More >
