Lipids in rye seedlings in relation to vernalization.
Increasing the chilling time from 1 to 8 weeks decreased the time to heading of winter rye (Secale cereale var. Sangaste) to approximate that of the spring variety (Prolific). On a dry weight basis, the total phospholipid content of the embryos was higher in Sangaste but declined in both varieties during chilling. The proportions of the individual phospholipid components were similar for both v...
متن کاملVernalization: winter and the timing of flowering in plants.
Plants have evolved many systems to sense their environment and to modify their growth and development accordingly. One example is vernalization, the process by which flowering is promoted as plants sense exposure to the cold temperatures of winter. A requirement for vernalization is an adaptive trait that helps prevent flowering before winter and permits flowering in the favorable conditions o...
متن کاملCold-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...
