Book ChapterDOI
Salinity Stress and Salt Tolerance
Petronia Carillo,Maria Grazia Annunziata,Giovanni Pontecorvo,Amodio Fuggi,Pasqualina Woodrow +4 more
TL;DR: In this chapter, soil salinity, its effects on plants and tolerance mechanisms which permit the plants to withstand stress are discussed, with particular emphasis on ion homeostasis, Na+ exclusion and tissue tolerance.
Journal ArticleDOI
Spatial and Temporal Profile of Glycine Betaine Accumulation in Plants Under Abiotic Stresses
Maria Grazia Annunziata,Loredana F. Ciarmiello,Pasqualina Woodrow,Emilia Dell’Aversana,Petronia Carillo +4 more
TL;DR: The ability of plants to accumulate high levels of GB in young tissues under abiotic stress, is independent of nitrogen (N) availability and supports the view that plant N allocation is dictated primarily to supply and protect the growing tissues, even under N limitation.
Journal ArticleDOI
Durum wheat seedling responses to simultaneous high light and salinity involve a fine reconfiguration of amino acids and carbohydrate metabolism
Pasqualina Woodrow,Loredana F. Ciarmiello,Maria Grazia Annunziata,Severina Pacifico,Federica Iannuzzi,Antonio Mirto,Luisa D'Amelia,Emilia Dell’Aversana,Simona Piccolella,Amodio Fuggi,Petronia Carillo,Petronia Carillo +11 more
TL;DR: The results showed that the complex interplay seen in durum wheat plants under salinity at LL was simplified: GB and antioxidants did not play a main role and the fine tuning of few specific primary metabolites remodeled metabolism and defense processes, playing a key role in the response to simultaneous stresses.
Journal ArticleDOI
Durum Wheat Roots Adapt to Salinity Remodeling the Cellular Content of Nitrogen Metabolites and Sucrose
Maria Grazia Annunziata,Loredana F. Ciarmiello,Pasqualina Woodrow,Eugenia Maximova,Amodio Fuggi,Petronia Carillo +5 more
TL;DR: Root cells adapt to salinity by sequestering sodium in the vacuole, as a cheap osmoticum, and showing a rearrangement of few nitrogen-containing metabolites and sucrose in the cytosol, thus providing plant viability even at low nitrate levels, which determines an increase of sap osmolality.
Journal ArticleDOI
Trehalose 6-phosphate is involved in triggering axillary bud outgrowth in garden pea (Pisum sativum L.).
Franziska Fichtner,François Barbier,Regina Feil,Mutsumi Watanabe,Maria Grazia Annunziata,Tinashe G. Chabikwa,Rainer Höfgen,Mark Stitt,Christine A. Beveridge,John E. Lunn +9 more
TL;DR: Data show that changes in bud Tre6P levels are correlated with initiation of bud outgrowth following decapitation, suggesting thatTre6P is involved in the release of bud dormancy by sucrose.
