Pale, soft, and exudative (PSE) meat is a growing problem in the turkey industry and has been associated with processing conditions such as slow carcass chilling. The development of PSE meat is caused by protein denaturation resulting from a rapid rate of pH decline early postmortem (PM) while carcass temperatures are still elevated. This research was conducted to determine the relationship of ...

Exposure to non-freezing temperatures below 10 °C causes an increase in the subsequent rate of ion leakage from chilling sensitive tissue (e.g. tomato fruit). The conditions of tissue preparation and conductivity measurements necessary to accurately calculate the rate of ion leakage from excised discs of tomato pericarp tissue were determined. Under the proper conditions, the rate of leakage ex...

Climate warming has forced the distribution of several fish stocks in one of Europe's major fishing grounds many kilometres north or to greater depths to find cooler waters, according to a study by climate change scientists. The distribution of major fish species, including cod and haddock, has shifted in response to an average 1 o C rise in the temperature at the bottom of the North Sea over t...

BACKGROUND Maize (Zea mays) is a C4 tropical cereal and its adaptation to temperate climates can be problematic due to low soil temperatures at early stages of establishment. METHODS In the current study we have firstly investigated the physiological response of twelve maize varieties, from a chilling condition adapted gene pool, to sub-optimal growth temperature during seedling emergence. To...

Information on the spatial distribution of arabinogalactan proteins (AGPs) in plant organs and tissues during plant reactions to low temperature (LT) is limited. In this study, the extracellular distribution of AGPs in banana leaves and roots, and their changes under LT stress were investigated in two genotypes differing in chilling tolerance, by immuno-techniques using 17 monoclonal antibodies...

Endogenous gibberellin (GA)-like substances were examined in suspension cultures of somatic embryos of a hybrid grape (Vitis vinifera x Vitis rupestris) during embryogenesis, and in mature embryos chilled at 4 degrees C, and subsequently incubated at 26 degrees C with and without abscisic acid (ABA). The extract was separated into a nonpolar fraction (would contain GA-precursors); a fraction th...

Chilling injury in cucumber (Cucumis sativus L.) is conditioned by maternal factors, and the sequencing of its chloroplast genome could lead to the identification of economically important candidate genes. Complete sequencing of cucumber chloroplast (cp)DNA was facilitated by the development of 414 consensus chloroplast sequencing primers (CCSPs) from conserved cpDNA sequences of Arabidopsis (A...

Cultivation of chilling-tolerant ornamental crops at lower temperature could reduce the energy demands of heated greenhouses. To provide a better understanding of how sub-optimal temperatures (12°C vs. 16°C) affect growth of the sensitive Petunia hybrida cultivar 'SweetSunshine Williams', the transcriptome, carbohydrate metabolism, and phytohormone homeostasis were monitored in aerial plant par...

Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...
