“…The reproductive phase consists of flower initiation, differentiation of male and female floral parts, micro-and mega-sporogenesis, development of male and female gametophytes (pollen grain and embryo sac), pollination, micro-and mega-gametogenesis, fertilization and seed development. All these stages respond differently to cold stress (Staggenborg and Vanderlip, 1996;Verheul et al, 1996) but collectively all responses are negative and reduce net yield.…”

The burgeoning population of world is expected to reach about 9-10 billion by the end of year 2050. Due to this rapidly increasing population, food productivity is decreasing. Temperature induced stress is an important environmental factor that influences the growth and development of plants. Both low and high temperatures affect plant growth and development at whole plant level, tissue and cell level and even at sub-cellular level. Temperature variation may affect morphology, anatomy, phenology and plant biochemistry at all levels of organization. Direct injuries due to high temperatures in plants include protein denaturation and aggregation, and increased fluidity of membrane lipids. Indirect or slower high temperature injuries include inactivation of enzymes in chloroplast and mitochondria, inhibition of protein synthesis, protein degradation and loss of membrane integrity. Low temperature stress during reproductive development induces flower abscission, pollen sterility, pollen tube distortion, ovule abortion and reduced fruit set, which ultimately lowers yield. A number of approaches are being used to alleviate the effect of temperature stress in crop plants. Proper plant nutrition is one of the good strategies to alleviate the temperature stress and in crop plants. Plant nutrients play a greater role in improving the temperature stress tolerance. In this paper we discuss the possible effective techniques to alleviate the temperature stress and the role of some macronutrients (nitrogen, potassium, calcium and magnesium) micronutrients (boron, manganese, and selenium) and salicylic acid in detail as how these nutrients play their role in alleviation of temperature stress in crop plant.

“…Several authors reported that chillingresistant species have more efficient antioxidant systems compared to the sensitive ones (Jahnke et al 1991, Walker and McKersie 1993, Wise 1995. In maize, antioxidant enzymes were not significantly affected by chilling in the dark (Anderson et al 1995).…”

The effects of low growth temperature on the activities of photosystems (PS) 1 and 2 and antioxidant enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione reductase (GR) and catalase (CAT) in leaves of various maize inbred and hybrid genotypes (parental lines, F1 hybrids, F2 and backcross generations) were investigated. Considerable decrease of the PS 2 activity (contrary to the activity of PS 1) due to low-temperature stress was observed in the majority of genotypes/generations examined. The GR, APX and SOD activities markedly increased due to chilling, whereas the activity of CAT showed lesser changes which depended on the genotype/generation analysed. The higher susceptibility of the inbred line 2013 to low temperature was transmitted to further generations in case this line was used as the maternal parent. The intraspecific variability in photosynthetic and antioxidant parameters was caused particularly by the dominance (negative or positive), however, the level of the expression of this effect often changed after low-temperature stress and was probably the cause of the increase in the positive F1 heterosis observed in this case. Other genetic effects (e.g. the additivity, and particularly the additive or dominant maternal effects) were also found to contribute to the intraspecific variability in parameters analyzed. The dominant maternal effects possibly played an important role in maintaining positive heterosis in F2 generation.

“…indentata) inbred line CM109 was used in experiments. This line was used before by several groups as a chilling-sensitive model line in physiological studies (Sowiński 1995;Kocsy et al 1996;Verheul et al 1996;Janda et al 1998;Haldimann 1999;Bilska-Kos et al 2017). Kernels were germinated in wet sand in darkness at 25 °C and seedlings were transferred to pots containing Knop's solution supplemented with Hoagland's micronutrient solution.…”

“…The maize inbred line used in this study, CM109, has been used in several studies before and its reaction to low temperatures under both field and controlled conditions is well characterized (Sowiński 1995;Kocsy et al 1996;Verheul et al 1996;Janda et al 1998;Haldimann 1999;Bilska-Kos et al 2017). Nevertheless, to verify how the plants react to the cold stress under the exact conditions used further to study the transcriptomic response, we performed basic measurements characterizing the photosynthetic efficiency and water potential in the cold.…”

numerous genes lacking circadian rhythm responded to the cold by undergoing up-or down-regulation. Notably, the transcriptome changes preceded major physiological manifestations of cold stress. In silico analysis of metabolic processes likely affected by observed gene expression changes indicated major down-regulation of photosynthesis, profound and multifarious modulation of plant hormone levels, and of chromatin structure, transcription, and translation. A role of trehalose and stachyose in cold stress signaling was also suggested. Meta-analysis of published transcriptomic data allowed discrimination between general stress response of maize and that unique to severe cold. Several cis-and trans-factors likely involved in the latter were predicted, albeit none of them seemed to have a major role. These results underscore a key role of modulation of diel gene expression in maize response to severe cold and the unique character of the cold-response of the maize circadian clock.
