keeping constant all agronomic factors except temperature is a way to follow heat shock proteins (hsps) expression. three different sunflower hybrids derived from the cross between an inbred line, cms ha 89, and three different restorer inbred lines, with resistance, susceptible, and normal reactions to drought, were produced. in order to investigate the impact of temperature on protein accumul...

Pinellia ternata is an important traditional Chinese medicinal plant. The growth of P. ternata is sensitive to high temperatures. To gain a better understanding of heat stress responses in P. ternata, we performed a comparative proteomic analysis. P. ternata seedlings were subjected to a temperature of 38 °C and samples were collected 24 h after treatment. Increased relative ion leakage and lip...

Knowledge of the origin and evolution of gene families is critical to our understanding of the evolution of protein function. To gain a detailed understanding of the evolution of the small heat shock proteins (sHSPs) in plants, we have examined the evolutionary history of the chloroplast (CP)-localized sHSPs. Previously, these nuclear-encoded CP proteins had been identified only from angiosperm...

All cells display a response to adverse environmental conditions by inducing the synthesis of a set of proteins, the heat shock proteins (Hsps). Hsp26 belongs to the family of small heat shock proteins (sHsps). The yeast Saccharomyces cerevisiae has three major sHsps: Hsp26 [I], Hspl2 [2] and Hsp30 [3]. Small Hsps have certain common structural and regulatory charactenstics; they are induced by...

Codling moth is a major pest of apples and pears worldwide. Increasing knowledge of how this insect responds to environmental stress will improve field and postharvest control measures used against it. The small heat shock proteins (sHsps) play amajor role in cellular responses to environmental stressors. A degenerate oligonucleotide primer, designed against the conserved α-crystallin domain, w...

sHSP (small heat-shock protein) IbpB (inclusion-body-binding protein B) from Escherichia coli is known as an ATP-independent holding chaperone which prevents the insolubilization of aggregation-prone proteins by forming stable complexes with them. It was found that the chaperone function of IbpB is greatly modulated by the ambient temperature, i.e. when the temperature increases from normal to ...

The small heat shock protein (sHsp) family is thought to play an important role in protein refolding and signal transduction, and thereby protect organisms from stress. However little is known about sHsp function and conservation across phylogenies. In the current study, we provide a comprehensive assessment of small Hsp genes and their stress responses in the oriental fruit moth (OFM), Graphol...

Small heat shock proteins (sHSPs) function as ATP-independent molecular chaperones, and although the production and function of sHSPs have often been described under heat stress, the expression and function of sHSPs in fundamental developmental processes, such as pollen and seed development, have also been confirmed. Seed germination involves the breaking of dormancy and the resumption of embry...

The small heat shock proteins form a large protein family comprising proteins important in the cellular stress response. Their ability to protect cells against heat shock and their increased expression as part of the heat shock response contributed to their assignment as heat shock proteins. As their molecular mass was usually less than 30, 000 the term ‘small’ was incorporated to distinguish t...

Muscle cells are frequently subjected to severe conditions caused by heat, oxidative, and mechanical stresses. The small heat shock proteins (sHSPs) such as alphaB-crystallin and HSP27, which are highly expressed in muscle cells, have been suggested to play roles in maintaining myofibrillar integrity against such stresses. Here, we identified a novel member of the sHSP family that associates sp...
