Cold-active winter rye glucanases with ice-binding capacity.
Extracellular pathogenesis-related proteins, including glucanases, are expressed at cold temperatures in winter rye (Secale cereale) and display antifreeze activity. We have characterized recombinant cold-induced glucanases from winter rye to further examine their roles and contributions to cold tolerance. Both basic beta-1,3-glucanases and an acidic beta-1,3;1,4-glucanase were expressed in Esc...
متن کاملEthylene induces antifreeze activity in winter rye leaves.
Antifreeze activity is induced by cold temperatures in winter rye (Secale cereale) leaves. The activity arises from six antifreeze proteins that accumulate in the apoplast of winter rye leaves during cold acclimation. The individual antifreeze proteins are similar to pathogenesis-related proteins, including glucanases, chitinases, and thaumatin-like proteins. The objective of this study was to ...
متن کاملAntifreeze proteins in winter rye leaves form oligomeric complexes
Antifreeze proteins (AFPs) similar to three pathogenesis-related proteins, a glucanase-like protein (GLP), a chitinase-like protein (CLP), and a thaumatin-like protein (TLP), accumulate during cold acclimation in winter rye (Secale cereale) leaves, where they are thought to modify the growth of intercellular ice during freezing. The objective of this study was to characterize the rye AFPs in th...
متن کاملVariability of winter rye grain yield in a glacial plain catchment — modelling and observation
Crop growth of winter rye (Secale cereale) was simulated on sandy soils in northwest Germany at the meso-scale (6 km2 catchment, 5 year rotation). Based on site-specific soil data, simulated grain yields (YMOD) were compared to observed yields OBS and the results were discussed with respect to the N balance. The mean annual yields simulated for rain-fed (3.8–7.3 t/ha) and irrigated conditions (...
متن کاملPolysomes from winter rye seedlings grown at low temperature : I. Size class distribution, composition, and stability.
We have studied the influence of growth at low temperature on size class distribution, stability and composition of leaf cytoplasmic polysomes from rye seedlings (Secale cereale, cv Puma) grown at 5 degrees C and at 20 degrees C. Leaves of seedlings grown at 5 degrees C contain 2.7 times more cytoplasmic polysomes (expressed on a DNA basis) and the polysome size class distribution is skewed tow...
