“…However, because this protein shows chaperone activity (Choi et al, 2004), it is possible that acting as a finely tuned sensor of stress, glycinin A1aB1b is efficiently up-regulated to cope with the adverse effects of environmental stressants in general, including heat, salinity and acidity (see text), waterlogging (Alam et al, 2010), Chilling (Cheng et al, 2010, and radioactivity (Danchenko et al, 2009). Reports on other proteins with hexameric structure and chaperone activity, reinforce this idea (Sauer et al, 2004;Lee et al, 2010).…”

“…These proteins are involved in many metabolic pathways, including those related to cell defense, energy, protein synthesis, cell growth/division, storage, transcription, and transport. Cheng et al (2010) found that alcohol dehydrogenase I and RAB21 may contribute in decreasing the effect of the anoxia resulting from water uptake during imbibition, whereas, stress-related proteins, such as LEA and GST24, probably play a pivotal role in reacting to low temperature stress. In addition, enhancements in levels of malate dehydrogenase and phosphoenolpyruvate carboxylase, which are involved in the tricarboxylic acid cycle, are associated with cold tolerance of seeds during germination.…”

“…Limited information is available regarding the proteome response of soybean subjected to cold stress. A differential proteome analysis of soybean seeds exposed to a low temperature (4 °C) during imbibition revealed a total of 40 affected protein spots of which 25 were upregulated and 15 were down-regulated (Cheng et al, 2010) (Table 1). These proteins are involved in many metabolic pathways, including those related to cell defense, energy, protein synthesis, cell growth/division, storage, transcription, and transport.…”

“…Within 20 min of imbibition at 25°C, an extensive reorganization of membrane structures occurs in the outer layers of cells in soybean seeds [10]. Cheng et al (2010) studied the changes in water absorption by changes in soybean seed weight during imbibition at 4°C and 22°C for 24 h. It was observed that the seeds imbibed at 22°C could absorb more water than those at 4°C during the same period. During phase I, seeds absorbed water rapidly, which slowed down in phase II, but it increased again in phase III.…”

Abstract-Germination is a key event in plant life cycle and imbibition temperature is an important factor for the major reorganization processes in the germinating seeds. Sub-physiological temperature at this stage affects virtually all aspects of cellular function including protein folding, kinetic parameters of membrane fluidity, protein assembly, and general metabolic processes. In this article we will review the research which has been carried out to decipher the basic mechanisms of low temperature (LT) stress with special emphasis on germination. With the better understanding of LT tolerance in some plant species we will also discuss how these attributes can be transferred in the important food crops to attain better germination stamina at sub-physiological temperatures. At germination stage, the cellular machinery in the embryo is not at its proper place and is going through reorganisation and any environmental severity has devastating effects on the fragile plant. But LT resistant species have evolved the ability to acclimatise, with the remodelling of cell and tissue structures and the reprogramming of metabolism and gene expression. Metabolic networks are redirected towards the synthesis of cryoprotectant molecules, which in association with other proteins bring about physical and biochemical restructuring of cell membranes through changes in the lipid composition and induction of other non-enzymatic proteins that alter the freezing point of water. Genetic engineering of crops for enhanced seed germination performance will certainly help to achieve optimum agricultural yields.. Germination physiology in low temperatureAll environmental stresses disrupt the normal functioning of a living system. To re-establish metabolic homeostasis, living systems require an adjustment of metabolic pathways in a process usually referred to as acclimation. For temperate plants, low temperature (LT) is a major non-living element of the environmental that affects water and nutrient uptake, membrane fluidity and protein and nucleic acid conformation, drastically influencing cellular metabolism directly by reducing the rates of biochemical reactions [1], accompanied by changes in the transcriptome, proteome and metabolome [2]. Chilling temperatures (0 to 15°C) frequently occur in nature and affect many species of plants, especially those of tropical origin (such as rice, corn, tomato and soybean), by causing wilting, chlorosis, or necrosis, thus restricting their growth and development. Metabolic rates are lowered which create energy imbalance. Freezing (0°C and below) temperatures cause membrane injury [3], decrease the respiration rate and ATP content [4], resulting in poor germination, reduced seedling emergence, decreased seedling vigour, and ultimately severe loss in yield of the food crops of tropical and subtropical origins [5][6][7][8][9]. Embryos, excised from seed coats of soybeans, leak profusely during the first minutes of imbibition. In the embryos imbibed at 10°C or lower, disproportionately more solutes leak ...
